Notice of 2024

Annual General Meeting of
Shareholders and Proxy Statement

MAY 1, 2024

MESSAGE FROM OUR BOARD CHAIR

John Cassaday

Chair of the Board

March 22, 2024

Dear Fellow Shareholders,

On behalf of our Board of Directors, we are pleased to invite you to the 2024 Annual General Meeting of Shareholders of Janus Henderson Group plc to be held on Wednesday, May 1, 2024, at 151 Detroit Street, Denver, Colorado 80206, USA, starting at 2:00 p.m. local time. Please read the following Notice of Annual General Meeting and Proxy Statement, as well as our 2023 Annual Report, carefully before you vote.

While 2022 was a year of strategic transition, 2023 was a year of significant progress at Janus Henderson. Throughout a difficult operating environment, your company delivered solid financial results, maintained a strong balance sheet, and generated healthy cash flow, which enabled us to return over $320 million to shareholders through dividends and share repurchases. Of particular importance, 2023 net outflows of $0.7 billion improved markedly from 2022 net outflows of more than $30 billion. As we mentioned last year, the strategy which we articulated in 2022, Protect and Grow, Amplify, and Diversify, is centered on the belief that a combination of relentless focus and disciplined execution across our core business will drive future success as a global active asset manager; our 2023 results demonstrate that we are beginning to realize the benefits of our renewed strategy, the deliberate investments we have made over the past two years in technology and people, and our simplified operating model.

In 2023, we introduced our company-wide Mission, Values, and Purpose, or “MVP.” Our MVP, coupled with our strategy, guides our decision making and prioritization, defines who we are and what we stand for, not just for today but what we want to be in the future. We believe that a deliberate and resonant organizational purpose can lead to higher levels of engagement, retention, and foster greater loyalty from clients. Our purpose, “Investing in a Brighter Future Together,” is a collective commitment to a future that benefits all stakeholders. Our five core values guide our daily operations and align our long-term goals with our purpose: Clients Come First – Always, Execution Supersedes Intention, Together We Win, Diversity Improves Results, and Truth Builds Trust.

This year, we would like to highlight one of those core values and how colleagues living our values have helped us to succeed and achieve our purpose of Investing in a Brighter Future Together with our clients, and their clients. We would like to share with you several examples where your Board has been made aware of associates embracing the core value of Clients Come First – Always. At a high-level, we achieve this through identifying with our clients and anticipating and prioritizing their needs, with a focus of delivering the highest quality, straightforward results. In practice, it means employees going above and beyond to put the client first.

One such collaborative effort where we have seen this exemplified is through the significant regulatory and operational efforts undertaken to address and even surpass client needs within our US Direct channel, including offering direct-to-consumer, tailored investment advice for the first time, meeting our clients as a trusted partner throughout their investing journey. We also enhanced and simplified our Direct website for a more beneficial client experience. Separately, we have expanded our Strategic Account Program, which provides specialized knowledge, amplified day-to-day partnering, and joint problem-solving to some of our largest clients, as we seek to build stronger, deeper, and uniquely differentiated ties with our clients through enhancing their business objectives.

Last year, we launched our first brand awareness advertising campaign in North America, which was tailored to raise awareness of our firm with the Intermediary audience. This campaign was predicated on reintroducing ourselves to the marketplace with credibility-building facts that give clients clear reasons to partner with us. We have also increased global client outreach and awareness of Janus Henderson through sponsoring or attending nearly 250 webcasts, wholesale events, and institutional events, reaching over 70,000 participants. With the world undergoing transformative change, our 2023 Knowledge Exchanges in both Madrid and London provided nearly 250 of our clients with in-depth insights and a dynamic and informative opportunity to share thinking with a wide range of Janus Henderson experts. Another important example of our outreach is our amplified efforts to reinforce our client experience when we have had portfolio management transitions. To demonstrate our commitment to deliberate and in-depth succession planning, clients are assured that we have well-defined career paths, extensive mentoring, and other tools and processes that will help our Investment teams continue to deliver high-quality investment results.

Each of these examples is a recent account of Janus Henderson employees putting the client first, and, as fellow stakeholders, we believe it is important for you to know how your company is embedding these values into every facet of the organization to achieve excellence in all aspects of our business.

In conclusion, in our 90^th anniversary year, we believe we are squarely on the path to achieving our ambitions of organic growth over time and delivering superior outcomes for all our stakeholders. Looking forward, the Board and Janus Henderson leadership will continue to control what we can control, including our effective cost discipline, ongoing investment in the business, world-class client outreach, and solid investment performance. We would also like to take this opportunity to thank Ed Garden, who stepped down from the Board in June 2023, for his significant contributions and valued insight. Also, in June 2023, Josh Frank and Leslie F. Seidman were appointed to the Board, and we appreciate the breadth and depth of their experience in assisting the Board in positioning Janus Henderson for future success.

As a shareholder, it is important that your shares are represented at the 2024 Annual Meeting in person or by proxy. You may vote your shares by internet, telephone, or mail pursuant to the instructions included on the proxy card or voting instruction form. Last year, approximately 85% of all eligible votes were cast by shareholders at the 2023 Annual Meeting, demonstrating the strong engagement and commitment of our shareholders to Janus Henderson.

On behalf of the Board of Directors, we thank you for your share ownership in Janus Henderson and your continued support. We hope you can attend our 2024 Annual Meeting.

Very truly yours,

John Cassaday

Company Strategy and 2023 Performance

Our strategy is focused on helping to define and serve our clients’ needs in a dynamic and competitive asset management landscape. Our strategic framework consists of three pillars: Protect and Grow our core businesses, Amplify our strengths not fully leveraged, and Diversify where clients give us the right to win.

We believe our strategy will deliver consistent organic revenue growth over time and desired results for our clients, shareholders, employees, and other stakeholders.

Progress will be measured in several ways:

■ Financially – We want to deliver consistent annual net new revenue growth with operating margin expansion over time.

■ For our clients – Results will be measured based on investment performance and our clients’ experience with Janus Henderson.

■ Organizationally – We will measure the ability to attract and retain top talent and the level of engagement from employees.

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 8

2023 Accomplishments

In 2023, we continued to make significant progress on repositioning Janus Henderson to better meet the needs of our clients – and their clients – and positioning the Company for future growth.

 

Executed Strategic Progress

We are in the execution phase of our strategy and have made progress across all three strategic pillars:

■ Protect and Grow – Annual net sales were positive for the US Intermediary business, our largest client segment, for the first time in seven years.

■ Amplify – Annual net sales were positive for the Global Institutional business for the first time since 2018. Diversified Alternatives, which includes multi-strategy and enhanced index strategies, generated positive annual net sales and over 35% growth in assets under management in 2023. Annual net sales were positive, in aggregate, for our suite of active exchange-traded funds (“ETFs”), which have increased 65% annually since 2018.

■ Diversify – We established Privacore Capital, a joint venture that aims to take advantage of the democratization of private alternatives into the retail channel.

 

Improved Net Sales

Net sales improved significantly to $(0.7) billion in 2023 from $(37) billion in 2022.

 

Reinforced Culture

We reinforced our culture through introducing our Mission, Values, and Purpose company-wide. It defines who we are and what we stand for as a collection of individuals and a firm, not just for today but what we want to be in the future. It gives us a clear North Star.

 

Achieved Cost Efficiencies

We achieved run rate cost efficiencies of more than $50 million by the end of 2023 compared to our original target of $40 to $45 million by the end of 2024.

 

Simplified Operating Model

We simplified our operating model, including upgrading our order management system to improve our efficiency in delivering for our clients, and we delisted from the Australian Securities Exchange, allowing us to focus on a sole, more active exchange and reduce costs.

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 18

PROPOSAL 1
ELECTION OF DIRECTORS

The Board has nominated 11 directors to serve on the Board until the 2025 Annual General Meeting of Shareholders (the “2025 Annual Meeting") and until their respective successors are duly elected and qualified or their earlier resignation or removal. All of the nominees currently serve on our Board of Directors.

If any nominee becomes unable to serve, proxies will be voted for the election of such other person as the Board may designate, unless the Board chooses to reduce the number of directors. Each of the nominees has consented to serve as a nominee, to be named in this Proxy Statement, and to serve on the Board if elected.

The text of the resolutions in respect of Proposal 1 (which are proposed as ordinary resolutions) is as follows:

RESOLVED,

■ That Brian Baldwin be elected as a director of the Company.

■ That John Cassaday be elected as a director of the Company.

■ That Kalpana Desai be elected as a director of the Company.

THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR EACH DIRECTOR NOMINEE.

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 19

CORPORATE GOVERNANCE

Our Board’s Leadership Structure

The Board is led by Mr. John Cassaday, our independent Chair. At least annually, the Board reviews its leadership structure — including whether the positions of Chair and CEO should be combined or separated — and the responsibilities and composition of its standing committees. The structure and composition of the Board and its committees are intended to promote effective oversight and the best interests of our shareholders.

The Board believes at this time that its current leadership structure, in which the roles of Chair and CEO are separated, best enables the Board to carry out its duties. However, the Board recognizes that the optimal leadership structure may change as circumstances evolve. Should the Board determine to combine the roles of Chair and CEO in the future, the Board’s independent directors will select an independent Lead Director, as required by the Company’s Corporate Governance Guidelines.

Director Independence

Our Corporate Governance Guidelines require that a majority of the Board consist of independent directors and include criteria for determining if a director is independent, consistent with the director independence requirements set forth in the NYSE listing standards. In determining the independence of the directors and director nominees, the Board reviewed and considered all relationships between each director (and any member of his or her immediate family) and the Company in light of these independence criteria. Based on that review, the Board affirmatively determined that, except for Mr. Dibadj, all our current directors and director nominees are independent as defined in the NYSE listing standards. In addition, all members of the Board’s four standing committees are independent as defined in the NYSE listing standards. The Board also previously determined that Ed Garden and Alison Davis, who each served as directors in 2023, satisfied the independence requirements of the NYSE listing standards.

Director Criteria and Nomination Process

The Company seeks a Board with an appropriate balance of skills, knowledge, experience, independence, and diversity of background among its members to enable it to discharge its duties and responsibilities effectively. The Board has delegated the process for identifying and screening potential director candidates to the Governance and Nominations Committee. When the Governance and Nominations Committee determines it is desirable to add a director or fill a vacancy on the Board, it identifies one or more qualified individuals and recommends them to the Board. The Governance and Nominations Committee may engage a third-party search firm to help identify qualified candidates. When engaging a third-party search firm to identify potential director candidates, the Governance and Nominations Committee instructs the search firm to include in its initial candidate list qualified candidates who reflect diverse backgrounds, including diversity of gender and race or ethnicity.

In evaluating candidates for potential membership on the Board, the Governance and Nominations Committee considers the qualifications of each candidate, the collective experience and expertise represented on the existing Board, and the following criteria set forth in our Corporate Governance Guidelines, among others:

■ Candidates should possess fundamental qualities of intelligence, honesty, perceptiveness, good judgment, maturity, high ethics and standards, integrity, fairness, and responsibility.

■ Candidates should demonstrate notable or significant achievement and possess senior-level business, management, or regulatory experience that would benefit the Company.

■ Candidates should be willing to spend the necessary time required to function effectively as a director.

■ Candidates’ other outside involvement and possible conflicts of interest.

■ Candidates should be able to work well with other directors and executives in a team effort with a view to a long-term relationship with the Company as a director.

■ Candidates should represent a diversity of viewpoints, backgrounds, experiences, and other demographics.

■ Candidates should be willing to form and articulate independent opinions in a constructive manner.

Based on that evaluation, the Governance and Nominations Committee recommends to the Board for nomination individuals whom it believes possess experience and expertise that will enhance the Board’s ability to serve our shareholders.

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 20

Process for Shareholder Recommendation and Nomination of Directors

The Governance and Nominations Committee will utilize the same criteria to consider candidates recommended by shareholders as those nominees recommended by management or other Board members. Shareholder nominations for election at the 2025 Annual Meeting must be submitted to the Company by the deadlines found on page 73 of this Proxy Statement.

Leslie F. Seidman, who joined the Board in 2023, was recommended by one of our independent directors. The Board also includes two directors, Brian Baldwin and Josh Frank, each of whom was recommended by, and is a partner of, Trian Fund Management, L.P., the Company’s largest shareholder (“Trian”). The Board has agreed to allow for replacement of these directors with another Trian partner if either Mr. Baldwin or Mr. Frank ceases to serve as a director of the Company before his term expires.

Board Refreshment and Tenure

We recognize the importance of Board refreshment to help ensure that our directors collectively possess the skills, experience, and qualifications necessary for the Board to successfully carry out its duties. Our Board also recognizes the value of having directors with significant Company knowledge and experience. To help ensure the Board’s composition strikes an appropriate balance, our Corporate Governance Guidelines contain director tenure and age limits. In particular, a director may not stand for re-election after serving for 10 years (though any director who was a Board member on May 30, 2017, may serve for 15 years from the date of their original appointment to the board of Henderson Group plc or Janus Capital Group Inc., as applicable). In addition, a director may not stand for re-election after reaching age 75 unless a specific exception is approved by the Board.

Since January 2022, the Board has added seven new directors who currently make up 64% of the Board, including four directors who are women or ethnically diverse. We believe that the fresh perspectives these new directors bring to the Board, combined with the knowledge and experience of longer-tenured directors, provide an appropriate balance of expertise, experience, continuity, diversity, and new viewpoints to our Board to serve the best interests of our shareholders.

Meaningful Refreshment Over the Past Two Years

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 21

The Risk Committee is responsible for assisting the Board in its oversight of risk, including by:

■ helping ensure that the key risks facing the Company are identified in a regular and timely fashion and are covered by either the Risk Committee, the Board, or by one of the other Board committees, including cybersecurity and information technology risks and operational and investment risks related to climate change and other ESG matters;

■ reviewing reports prepared by the Company’s Chief Risk Officer.

All 11 of our then-current directors attended our 2023 Annual General Meeting of Shareholders (the “2023 Annual Meeting”) in person, in accordance with the expectations set forth in the Company’s Corporate Governance Guidelines.

Board Evaluations

The Board believes that a constructive evaluation process is key for maintaining and improving the effectiveness of the Board and its committees. The Board and each of its committees conduct an annual evaluation to assess how they are functioning, and in 2023 the Board also conducted an evaluation of the Board Chair’s performance in his role. Throughout the evaluation process, which is overseen by the Governance and Nominations Committee, each director is given substantial opportunity to provide feedback. In 2023, each director completed a comprehensive annual questionnaire covering a range of topics including Company strategy, management, Board materials and meeting practices, the Board Chair’s performance, Board and committee composition, shareholder engagement, and other areas specific to each committee. A report was prepared for the Board, each committee, and the Board Chair summarizing the questionnaire responses, and the results of the performance evaluation were discussed with the full Board, each standing committee, and the Board Chair.

Director Orientation and Continuing Education

When new directors join the Board, we provide an orientation program to familiarize them with the Company’s business; strategic plans; significant financial, accounting, and risk management issues; compliance programs; conflicts policies; Code of Business Conduct; Corporate Governance Guidelines; principal officers and business leaders; and internal and independent auditors. During Board meetings, the Company’s management team frequently presents on the Company’s goals and strategies and the current competitive environment. Further, the Board frequently receives presentations on various topics, including key industry trends, topical business issues, ESG, DEI, risk management, cybersecurity, and corporate governance. These presentations help our directors understand the Company and its industry and maintain and develop their expertise.

In addition, each director is expected to participate in continuing education programs, at the Company’s expense, to maintain the necessary level of expertise to perform his or her responsibilities.

Shareholder Engagement

We conduct an active investor relations program, maintaining open dialogue with our shareholders and engaging on a range of topics, including corporate governance, our philosophy, and practices relating to ESG, executive compensation, strategic priorities, and financial and business performance.

In 2023, management and the Investor Relations team conducted over 150 individual or group meetings with existing shareholders, representing approximately 55% of our common stock outstanding, and potential investors in the UK, Europe, Asia, and the US. The majority of our shareholder engagement meetings were conducted virtually during the year, but in-person engagement increased in 2023 with a non-deal roadshow in the US, participation in industry conferences, and meetings at investors’ offices.

The Board regularly receives feedback on shareholder sentiment and sell-side analysts’ views of the Company and the wider industry.

The Chair of the Board, each time accompanied by another director, also conducted a number of outreach meetings throughout 2023 with major shareholders representing approximately 46% of our common stock outstanding. Our directors welcomed the opportunity to learn more about shareholders’ interests in the Company and management received updates on shareholder engagement, topics raised, and key discussion points.

Trian Fund Management, L.P. is the Company’s largest shareholder and owns approximately 19.8% of our outstanding common shares. Since February 2022, two directors recommended by Trian have served on our Board. In June 2023, one of these directors, Mr. Garden, resigned from the Board and Josh Frank, Partner and Co-Chief Investment Officer at Trian, was appointed to the Board. We are pleased to have Trian as a major shareholder and to have the opportunity to benefit from the deep industry experience, fresh perspectives, and valuable insights that Messrs. Baldwin and Frank bring to our Board as we continue to help clients define and achieve their desired investment outcomes while delivering significant long-term shareholder value.

The following table provides examples of our engagement efforts and topics discussed with our current and prospective shareholders:

Types of Engagement	Topics Covered

BOARD COMPENSATION

Our Compensation Philosophy for Non-Executive Directors

The Governance and Nominations Committee of our Board is responsible for periodically reviewing non-executive director compensation and benefits and recommending changes, if appropriate, to the full Board. Our non-executive director compensation program is designed to accomplish several objectives:

■ Attract and retain a diverse mix of capable and highly-qualified directors with the ability, integrity, experience, and judgment required to serve on the board of a public company;

■ Provide competitive compensation commensurate with the scope of responsibilities and time commitment required by the Company’s directors, including service on Board committees; and

■ Align the interests of our non-executive directors with those of our shareholders.

Fees and Other Compensation in 2023

The Governance and Nominations Committee conducts a review of non-executive director compensation every other year. The table below shows the annual service fees for the Chair of the Board and other non-executive Board members as well as committee services fees for the period commencing on the 2023 Annual Meeting date through the 2024 Annual Meeting.

Annual Service Fees
Chair of the Board(1)
Cash	$	250,000
Stock	$	285,000
TOTAL	$	535,000
Board Members
Cash	$	100,000
Stock	$	150,000
TOTAL	$	250,000
Cash per each Committee
Audit Chair	$	40,000
Other Committee Chair	$	20,000
Per Committee	$	15,000

(1) The Chair does not receive separate committee fees.

The annual retainer and fees noted above are prorated for the period of time during the calendar year that each director held the position. Annual cash service fees are paid in arrears in quarterly increments. Stock awards are paid in fully vested shares of Company stock, though directors who have met the ownership requirement have the option to receive all or part of their stock awards in cash. The Company also reimburses travel expenses for Board meetings, which are not included in the compensation tables below.

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 27

Stock Ownership Guidelines

To ensure that directors own a meaningful amount of JHG common stock to align their economic interests more closely with those of other shareholders, the Governance and Nominations Committee has set minimum stock ownership guidelines for non-executive directors, which were adopted by the Board in the Corporate Governance Guidelines. Non-executive directors are required to own shares or share equivalents of our common stock with a value of at least $400,000 within five years of joining the Board. Non-executive directors are not permitted to sell shares of the Company’s common stock until they have met the ownership guideline. All our current non-executive directors have satisfied the ownership guidelines as of December 31, 2023, except for John Cassaday, Alison Quirk, Leslie F. Seidman, and Anne Sheehan, each of whom joined the Board within the past five years. In addition, solely for purposes of satisfying the ownership guidelines, all the shares of Company common stock beneficially owned by Trian Fund Management, L.P. are deemed to be owned directly by Brian Baldwin and Josh Frank, so Messrs. Baldwin and Frank have each satisfied the ownership guidelines.

2023 Annual Compensation for Non-Executive Directors

RESPONSIBLE INVESTING

Embedding Responsibility Across Our Business

Companies and society face an array of challenges in the 21^st century. Climate change, pollution, and other environmental crises are compounding existing social issues like access to food, water, and healthcare. The rise of big tech and artificial intelligence could unlock enormous benefits to humanity but could also threaten jobs, cybersecurity, and data privacy. Because these ESG issues are complex, often interlinked, and can pose long-term, financially material* risks – and opportunities – for investors, they demand active and ongoing engagement and we are committed to maintaining our focus on ESG as a foundation for long-term investment returns. At Janus Henderson, our approach to Responsibility is built on three pillars:

■ Corporate Responsibility. Our commitment to Responsibility starts with us. At a corporate level, ESG principles influence our people, our culture, and our choices, helping to make us a better company.

■ ESG Integration. At an investment level, we integrate financially material ESG factors into our analysis and processes for most of our actively managed strategies, as appropriate, to help us identify opportunities and risks and influence positive change to drive long-term performance as we engage with the companies in which we invest.

■ Our JHI Brighter Future Funds. For clients who want to invest for a purpose beyond risk and return, we have, and continue to build, our suite of ESG-focused strategies that have dual objectives – an explicit ESG objective, alongside a financial objective.

To help emphasize the importance of our Responsibility efforts and ensure they are embedded across our entire Company, we enhanced our governance and oversight processes in 2023 around financially material ESG and climate considerations:

■ We appointed a Chief Responsibility Officer, who reports directly to the CEO and is a member of the Strategic Leadership Team, to guide and shape our ESG strategy and governance;

■ Our Board of Directors reinforced its commitment to Corporate Responsibility and Responsible Investing by amending its Committee charters to assign primary oversight of ESG matters to the Governance and Nominations Committee, with assistance on specific aspects of ESG from the Risk and Audit Committees, as described in more detail in the “Committees and Membership” section above; and

■ Our overall risk management framework was enhanced to support our ESG Integration pillar by identifying scenarios where risks to our business and assets under management capture ESG factors and are run through our Risk and Control Self-Assessment process.

In addition to this new governance structure, our ESG Oversight Committee continues to provide oversight across a range of issues at a portfolio and security level, and regular management meetings are organized around various ESG topics. The mandate of our ESG Oversight Committee is to ensure our investment management framework is adequate and effective for managing financially material ESG risks, including credibility of portfolio names and methodologies and effectiveness of internal controls.

Our approach to incorporating these risks and opportunities into our management structure has broadly been to integrate with existing frameworks, rather than creating a parallel structure specifically for ESG. ESG is not something distinct from investing, and we believe that the financial impact of material ESG risks and opportunities should be incorporated at various stages of the research process.

Our Commitment to Clients

Responsible Investing involves considering ESG factors when making portfolio decisions and engaging in stewardship activities. We understand that Responsible Investing continues to evolve and mature. We are committed to maintaining an open dialogue with our clients, shareholders, employees, industry groups, and regional regulators to ensure we continue to meet their expectations and hold true to our values as a steward of our clients’ capital. This includes listening to client needs and developing new products to meet changing requirements.

As part of our commitment to advancing the industry dialogue around ESG, we seek to make the thinking of our Investment teams widely available to our clients, shareholders, and other stakeholders through a variety of content, including white papers, articles, podcasts, videos, and panel debates. As with our ESG research, we aim to publish content that contains thoughtful, practical, research-driven, and forward-looking insights.

In 2023, we generated 28 thought leadership and educational pieces on ESG topics. The insights included portfolio manager-specific views related to sustainable investment themes with key contributions from our Global Sustainable Equities, Global Natural Resources, and Global Technology Leaders teams. This content, as well as our ESG policies, voting records, and our annual ESG engagement and voting review, can be found on our website at ir.janushenderson.com under “Corporate Governance – Corporate Social Responsibility.”

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 29

Our Approach to Responsible Investing

Responsible Investing demands active and ongoing engagement, and our heritage and expertise in fundamental research enable us to target long-term sustainable returns and positive outcomes.

Our Responsible Investing Principles for Long-Term Investment Success
1.	Investment portfolios are built to maximize long-term, risk-adjusted returns for our clients
2.	Evaluation of financially material ESG factors is a fundamental component of our investment processes
3.	Corporate engagement is vital to understanding and promoting business practices that position the companies we invest in for future success
4.	Investment teams should have the freedom to interpret and implement ESG factors in the way best suited to their asset class and strategy objective, as they do for any fundamental investment factor

Our approach to ESG integration at Janus Henderson is thoughtful, practical, research-based, and forward-looking. We identify financially material ESG issues and, leveraging our long-standing focus on deep research, assess the impact of these issues on various outcomes such as cash flows, valuations, and discount rates. Our analysts and portfolio managers are at the heart of this process. They are sector and company experts and are best placed to assess the impact of ESG issues on our clients’ investments.

Our Investment teams are supported throughout the research and client engagement process by our central Responsibility team, an ESG-specialized group that oversees an array of ESG functions, including strategy and operations, client solutions, and Responsible Investment and governance practices across the Company. This partnership leads to enhanced research and decision-making, marrying the sector and industry expertise of the Investment teams with the ESG knowledge of the Responsibility team.

The Responsibility team is led by our Chief Responsibility Officer who reports directly to the CEO and regularly engages with our Board through quarterly updates on established metrics and targets, progress reports on priority initiatives, and various educational sessions.

The Responsibility team is organized around four resource and support functions:

Responsibility Team
ESG Strategy & Operations	Responsible Investment & Governance	ESG Client Solutions	Diversity and Community Relations
Supports our non-Investment teams through strategic initiatives such as Responsible Investment strategy, policy, and partnerships; ESG data and analytics; content and learning; and regulatory and operations matters by collaborating with our Regulatory, Risk, Compliance, and Legal teams.	Partners with the Investment teams to deliver ESG training, support on developing frameworks to identify financially material ESG issues, planning and conducting engagements, supporting research on ESG issues that can impact cash flows or valuation, and advising on proxy voting.	Partners with our Product, Distribution, and Investment teams to enhance existing portfolios and deliver new portfolios to clients with varying levels of ESG needs, from robust integration to ESG-focused strategies.	Partners with our Product, Distribution, and Investment teams on DEI matters, community relations, and oversees the Janus Henderson Foundation.

Stewardship and Engagement

Stewardship is an integral and natural part of our long-term, active approach to investment management. Strong ownership practices through engagement with issuers and voting proxies can help protect and enhance long-term shareholder and bondholder value. We support several stewardship codes, such as the UK and Japanese stewardship codes, and broader initiatives around the world, including the Principles for Responsible Investment, a UN-supported network of investors working to promote sustainable investment through the incorporation of ESG factors, of which Janus Henderson is a founding member.

In general, our Investment teams prefer an engagement-focused approach to a firm-level exclusion or divestment policy, both in sectors with higher environmental risk and for issuers where we have identified financially material sustainability, climate, or ESG risks. We believe this approach is best for maximizing risk-adjusted returns for our clients and for driving positive change at our portfolio companies. Most products and services offered by an issuer play necessary roles for the global economy, including sectors with higher carbon emissions such as oil and gas, mining, industrials, and utilities. Rather than ignoring issuers in these sectors through automatic exclusion or divestment, engagement leads to two benefits:

■ Insight. Our Investment teams can engage for insight – the knowledge gained through engagements with issuers can be leveraged in the investment process to better inform our research, modeling, and investment decisions. Engaging for insight helps us assess the magnitude of any potential risk, how well an issuer is managing that risk, and the potential impact on that issuer’s financial outcomes.

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 30

■ Outcomes. Our teams can also engage for outcomes. Where an issuer may be ignoring or not managing a financially material sustainability, climate, or ESG risk, engaging for outcomes can encourage that issuer to adopt policies or practices that will address that risk and better position it for the future.

Discussions with the issuer’s management or board of directors directly link the sustainability, climate, or ESG consideration to why we believe addressing it makes them a better company, leading to improved cash flows, valuations, cost or capital, or credit ratings.

We have three core themes that all our Investment teams engage companies on:

■ Climate change

■ DEI

■ Corporate governance

In addition to these, we have a wide range of engagement themes and topics chosen by individual Investment teams, supported by the expertise of our Responsible Investment and Governance teams. These range from longstanding engagement themes such as access to medicine and human capital and culture to newer topics such as biodiversity and sustainable design.

Proxy Voting

Corporate governance regimes vary significantly depending on factors such as the relevant legal system, extent of shareholder rights, and level of dispersed ownership. Janus Henderson varies its voting and engagement activities according to the market and pays close attention to local market codes of best practice. However, we consider certain core principles to be universal:

■ Disclosure and transparency

■ Board responsibilities

■ Shareholder rights

■ Audit and internal controls

A key element of our approach to proxy voting is to support these principles and to foster the long-term interests of our clients. We also recognize that, in some instances, joint action by shareholders has the potential to be more effective than acting alone, especially when shareholders have a clear common interest. Where appropriate, we proactively collaborate with other investors on governance and wider environmental and social engagement issues, directly and through industry bodies.

We have a Proxy Voting Committee, which is responsible for positions on major voting issues and creating guidelines to oversee the voting process. The Proxy Voting Committee is comprised of representatives with experience in investment portfolio management, corporate governance, accounting, operations, legal, and compliance. Additionally, the Proxy Voting Committee is responsible for monitoring and resolving possible conflicts of interest with respect to proxy voting. We make our voting records publicly available on our website at ir.janushenderson.com under “Corporate Governance – Corporate Social Responsibility.”

2023 Update

Responsibility is a journey and we continually aim to strengthen our Corporate Responsibility practices and ESG capabilities. In 2023, we made progress in embedding Responsibility at the heart of our investing proposition through further investments in ESG personnel, data, infrastructure, and fund capabilities. Key accomplishments during the year included:

■ Specialist ESG Resources. We further strengthened our in-house Responsibility team which supports and partners with our Investment teams and non-Investment teams across an array of specialist ESG functions.

■ ESG Governance. We enhanced our governance and oversight process around financially material ESG and climate considerations, as described in more detail above.

■ ESG Data and Tools. We took our first steps in a larger initiative and provided some of our Investment teams with access to an ESG and climate dashboard which showed select ESG and climate metrics for portfolio companies. We are in the process of finalizing a new Company-wide proprietary portfolio and issuer ESG data dashboard called ESG Explore that will be available in early 2024. ESG Explore will show portfolio-level analytics for the sustainability factors we believe to be most material for all sectors and companies. We expect that ESG Explore will help us uncover underappreciated risks and opportunities for the companies in which we invest, including by alerting us to changes and drawing attention to leaders and laggards across regions, sectors, and issuers.

■ ESG Fund Developments. Driven by client interest and following regulatory guidance, we expanded and diversified our suite of products that incorporate ESG or sustainability factors. In 2023, we aligned a further seven products with the European Union’s Sustainable Finance Disclosure Regulation (“SFDR”) to Article 8 status, giving us 35 funds with Article 8 status and three funds with Article 9 status (38 funds in total) under this framework. We believe reporting in line with the SFDR is a significant step in providing greater disclosure and transparency on a range of ESG metrics at both entity and product levels, thus allowing our clients and other financial market participants to make more informed investment decisions.

We are also committed to leveraging research-driven, materiality-focused ESG integration, alongside fundamental investment factors. This type of ESG integration is reflected in over 80% of our products. Beyond ESG integration, we also understand that many clients are looking to pursue environmental or social outcomes alongside targeted financial outcomes. For these clients, we continue to develop our suite of JHI Brighter Future Funds, which aim to deliver superior financial outcomes as well as environmental or social outcomes aligned to long-term sustainability themes. In alignment with our goal to offer investments that resonate with our clients’ values, we currently offer various strategies under our JHI Brighter Future Funds and continue to build a pipeline of strategies that address clients’ ESG goals across asset classes and strategies.

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 31

■ ESG Research and Engagement. Our Responsibility team partnered with our Investment teams to develop thematic ESG research covering a wide range of topics in 2023. This includes research on nuclear energy, cybersecurity, regulation of internet mega caps, climate stress tests, and physical climate risks/renewable energy opportunities in real estate. We also advanced stewardship of our holdings by conducting over a thousand company meetings where ESG topics formed part of the discussion.

■ Internal ESG Training. The Responsibility team continued its efforts to upskill our Investment teams’ knowledge and expertise in ESG topics by presenting regular training and research on ESG megatrends and themes. Recent sessions have included:

■ ESG analysis: Financial materiality frameworks, climate data, and conducting outcome-oriented engagements

■ ESG thematic topics: Climate change, DEI, and human capital management

■ Sectoral topics: Utilities, chemicals, gambling, and tobacco

Various members of the Responsibility team completed the Chartered Financial Analyst (“CFA”) Program, the Certificate in ESG Investing from the CFA, and the climate-related Financial Risk Program with the University of Oxford. They also participated in additional training focused on building both ESG and non-ESG related skills, including the Durrell Wildlife Conservatory’s biodiversity course.

Training efforts extend beyond the Responsibility and Investment teams with over 90% of client-facing Distribution personnel now having obtained an external ESG certification. We will continue to develop ESG research insights across a variety of topics and hope to enhance the depth of these insights through a partnership with an academic institution that will provide support on both training and research.

■ ESG Insights. Following our Knowledge Shared approach, we generated 28 thought leadership and educational pieces on a variety of ESG topics, including methane emissions from the oil & gas industry, deforestation, the role of metals in decarbonization, renewable energy, and electric and autonomous vehicles. We also published articles outlining our approach to ESG and natural capital investing. We aim to share these insights more broadly with our clients and other external stakeholders, through more personal and interactive events. One example is an event on the investment implications of the global water crisis that Janus Henderson and the Carbon Disclosure Project (*CDP *), an international non-profit organization, hosted in October 2023.

■ Industry Initiatives. In 2023, we became a participant in Nature Action 100, a global investor engagement initiative focused on driving greater corporate ambition and action to reverse nature and biodiversity loss. Additionally, Janus Henderson has a strong heritage of involvement with other sustainability-related organizations and initiatives. A complete list is available in our most recent Responsibility Report which can be found on our website at the address provided in the “Our Commitment to Clients” section above.

CORPORATE RESPONSIBILITY

Commitment to Diversity, Equity, and Inclusion

We are committed to creating an inclusive environment that promotes equality, cultural awareness, and respect by implementing equitable policies, benefits, training, recruiting, and recognition practices to support our employees. DEI is about valuing our differences, creating equal opportunities, and continually identifying ways to improve our cultural intelligence, which ultimately leads to better decision-making and a more tailored client experience.

We view diversification in our people to be just as important as diversification of our investment portfolios. In 2023, we identified new ways to bring to life our value of Diversity Improves Results. We took calculated and measured steps to ensure we create accountability and leveraged quantitative and qualitative data to measure our overall impact, identified process improvements, and strived to create a workforce that reflects the communities in which we operate.

Our DEI Metrics
20%	11%
Women in senior management positions	Racially and ethnically diverse employees in senior management positions

To measure and drive results, we use activity metrics such as the number of employees that participate in DEI-related events. Process metrics are used to evaluate and determine gaps that could occur in our performance management and recruitment efforts. We leverage lagging and leading indicators such as representation data, employee engagement scores, and talent pipeline to provide insight into our inclusion and equity efforts. In addition to disclosing these measurable objectives for achieving diversity, we also disclose how we support DEI with our leadership and talent development curriculum as well as share the future state of DEI at Janus Henderson in our Responsibility Report, which is available on our website at ir.janushenderson.com under “Corporate Governance – Corporate Social Responsibility.”

Employees value our employee resource groups, which include the Ability Alliance, Gender Diversity Alliance, the Black Professional Network, and Janus Henderson Pride, to name just a few.

KEY DEI ACCOMPLISHMENTS IN 2023:

■ Enhanced our global parental leave coverage and leave pay.

■ Increased the number of employees with disabilities by 1% to 8% compared to 2022.

■ Implemented interview training for hiring managers and reinforced our commitment to having diverse interview panels and candidates for open roles.

■ Streamlined our job descriptions to remove unintended barriers and created them for the skill sets needed for tomorrow.

■ Faciliated over 35 sessions focused on topics such as neurodiversity, allyship, sign language, single parenting, belonging, and mental health support for men in the workplace.

■ Designed and implemented new employee curriculum focused on accent bias and socioeconomic diversity.

■ Achieved a DEI employee engagement score of 85%, which is aligned with the 75^th percentile industry benchmark set by Newmeasures, LLC, a nationally certified women-owned enterprise that designs and executes employee lifecycle survey tools and benchmark data.

■ Sustained our commitment to the CEO Action for Diversity & Inclusion pledge and Women in Finance Charter and continued to partner with the Diversity Project.

■ Recognized for the past five years by the Bloomberg Gender-Equality Index and Human Rights Campaign Index for our inclusive practices and received 100% on the Human Rights Campaign Foundation Index.

■ Received the LGBT Great Gold Standard designation for our inclusive policies.

■ Continued our partnerships with #10000BlackInterns, Investment 2020, and Greenwood Project internship programs.

■ Globally, our base pay gender pay gap has continued to improve year-over-year but our mean bonus gap slightly increased due to outperformance in a specific portion of our investor base with low female representation.

Corporate Sustainability

Climate change, biodiversity loss, and pollution are some of the greatest challenges we, as a society, face today, and we recognize that urgent action is imperative to prevent irreversible consequences to the planet. We are committed to reducing our environmental impact and embedding sustainable practices throughout our business.

Our highlights:

■ In 2021, we reached our target of reducing our carbon footprint by 15% per full-time employee over three years, based on 2018 consumption, on both actual emissions (which were lowered significantly due to the impact of COVID-19) and business-as-usual modeling (which aims to normalize this reduction). In 2022, we set new science-based aligned reduction targets on our global upstream operational emissions using 2019 as a new baseline, as discussed in our Responsibility Report.

■ In 2022, we improved our carbon data collection process by expanding its scope to include fugitive gases, working-from-home emissions, and electricity transmission and distribution losses.

■ In 2023, we procured 100% renewable electricity for all our global offices through energy contracts, renewable energy certificates, and guarantees of origin.

■ We are a signatory to the CDP and have been responding to its Climate Change Questionnaire since 2010. In 2023, we achieved a ‘B’ score, outperforming our peers in over half of the CDP’s scoring categories as well as scoring higher than the global average of ‘C’. A ‘B’ Score is in the CDP’s ‘Management’ band, indicating that we have addressed the environmental impacts of our business and ensure good environmental management.

■ Through our carbon offsetting portfolio, we contributed to high quality, independently verified emission reduction and removal projects and advanced the UN Sustainable Development Goals. Our 2023 Offset Portfolio includes:

■ Domestic Energy Systems, India

■ Seneca Meadows Landfill Gas, USA

■ Solar Water Heating, India

■ Truck Stop Electrification, USA

■ Wind Power Portfolio, Turkey

UN Sustainable Development Goals advanced through our offset portfolio:

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 34

Community Involvement

We are committed to creating a culture of giving, and our commitment to the community and goals align with our purpose of Investing in a Brighter Future Together. Our people are involved, inspired, and invested through our employee-led giving and volunteering efforts. By contributing to communities through local initiatives, as well as through our investment activity and corporate engagement, we are fulfilling what we view as our civic responsibility to set a positive example.

Through financial donations, service projects, and paid volunteer hours, employees are able to positively engage in the areas where we work and live, strengthening our communities and cultivating meaningful partnerships. In 2023, we were able to engage in some of our traditional philanthropic efforts like participating in hunger relief campaigns and community projects, early childhood literacy programs, and teaching financial literacy in the classroom. Our employees volunteered approximately 2,600 hours in the community which was an increase compared to the 2,000 hours recorded in 2022. In addition, they continued to organize fundraising campaigns for those in need.

During our global month of service campaign:

■ Colleagues volunteered with Food for Thought to assemble over 1,500 Power Snacks for children in the Denver Metro area facing greater food insecurity now more than ever.

■ Employees in Denver donated toiletry items to the Delores Project for individuals experiencing a barrier to housing and collected food to donate to FoodBank of the Rockies which provides food and necessities to more than 800 hunger relief partners across Colorado and Wyoming.

■ Janus Henderson’s colleagues across the globe, including Tokyo, Hong Kong, and Singapore offices, donated blood. The Denver office hosted a Children’s Hospital Colorado Mobile Blood Drive and collected donations to help save or enhance up to 85 children’s lives.

■ Colleagues in Japan volunteered at Good Gohan, a part of Good Neighbours, to provide educational support, medical and health assistance, and vocational training. Good Gohan strives to improve children’s lives through education, food, shelter, community development, medical care, advocacy, and emergency relief projects.

■ In the London office, employees donated money, emergency food, and household items to the Hackney Food Bank for local people in crisis.

■ A group of volunteers took part in the FoodCycle Food Challenge. In teams, they had to devise a menu using new food which was judged by the charity before they delivered the dishes to St. Mungo’s Homeless Kitchen in London.

The Janus Henderson Foundation

The Janus Henderson Foundation is the primary charitable giving arm of Janus Henderson Group. The Janus Henderson Foundation’s mission is to Invest in a Brighter Future Together by helping youth achieve their full potential, enhancing educational opportunities in our communities, and supporting the ideas and passions of our employees.

Select 2023 Partnerships:

■	Greenwood Project. The Janus Henderson Foundation is excited to be in year two of our three-year grant with Greenwood Project. Greenwood Project creates career pathways in the financial services industry for Black and Latino students through rigorous training and internships. The $450,000 grant from the Janus Henderson Foundation has allowed high-achieving, underserved students to participate in the program and focus their training in a financial services bootcamp.
	In addition, The Janus Henderson Foundation has helped Greenwood Project to expand its student recruitment efforts beyond the Chicago area by hosting an information session in Denver. Education, business, and non-profit community leaders came together to learn about Greenwood Project and how to partner with the organization.
	In 2023, we provided additional funding to the organization to support a seminar for their college scholars. The seminar featured Nobel Prize winner and Janus Henderson Chief Investment Strategist Myron Scholes, Ph.D. The topics covered included decarbonization, innovation, compound returns, risk management, asset and option valuation, behavioral finance, and more. Dr. Scholes also talked about his background in economics and the significant contributions he’s made to the field.
	The Janus Henderson Foundation is proud to support Greenwood Project and sees natural alignment in the organization’s mission. We are also grateful for our employees who host interns and volunteer their time and resources to support underserved students looking to pursue careers in financial services.
■	Denver Scholarship Foundation. The Janus Henderson Foundation proudly continues its partnership with the Denver Scholarship Foundation (“DSF”). This year, we are pleased to announce that we are inspiring another 14 scholars through the DSF Named Scholarship supported by Janus Henderson Scholarship. DSF is committed to ensuring students can access these necessary resources and maintain forward momentum. Since the partnership’s inception, we have been able to support and provide scholarships to over 60 youth in our community.
■	Causeway Education. Janus Henderson Scholarship has also partnered with Causeway Education to establish a scholarship for youth in the United Kingdom pursuing a degree in finance. Causeway is focused on supporting young people facing barriers to higher education, apprenticeships, and early careers. This scholarship is designed to help create social mobility opportunities so youth can participate in, and gain access to, work experience opportunities while in school.
■	Charity Challenge. The Charity Challenge continues to be the largest employee-led giving initiative at Janus Henderson. This year we saw many compelling entries and contributed $210,000 to employee-nominated charities. Since inception, we have donated over $1,731,816 to 350 charities around the world based on nominations from our employees.

LETTER FROM THE CHAIR OF OUR HUMAN CAPITAL AND COMPENSATION COMMITTEE

Dear Fellow Shareholders,

On behalf of the Human Capital and Compensation Committee and the entire Board of Directors of Janus Henderson Group plc, we are pleased to present our Compensation Discussion and Analysis for 2023. This section of our Proxy Statement provides insights into our compensation program, including the decisions made by the Committee throughout the year.

Progress on our Transformation and 2023 Performance

During 2023 there were several signs of clear progress towards our ambition of achieving organic revenue growth over time:

■ We executed on our three strategic pillars of Protect and Grow, Amplify, and Diversify.

■ Improved net flows significantly to $(0.7) billion compared to net flows of $(30.8) billion in 2022.*

■ Reinforced our culture through articulating our Mission, Values, and Purpose.

■ Achieved cost efficiencies better than target by the end of 2023, higher and sooner than the original target of the end of 2024.

■ Simplified the operating model, including signficantly upgrading our order management system and delisting from the Australian Securities Exchange.

■ Returned $321 million of cash to shareholders through quarterly dividends and the share buyback program while maintaining flexibility to invest in the business.

Additional details on our financial performance can be found in the “2023 Company Highlights” section of this CD&A.

Pay and Performance for 2023

The Committee is focused on aligning the executive team’s interests with those of our shareholders through the design of a performance-based compensation program that focuses on achieving rigorous financial and strategic goals.

Our significant operational and strategic achievements in 2023 resonated with the market as demonstrated by the over 36% in total shareholder return (“TSR”) generated by JHG common stock during the year. Our TSR for 2023 outpaced the S&P US BMI Asset Management & Custody Bank Index by approximately five percentage points. In making our compensation decisions, in addition to focusing on financial and strategic performance, we rewarded outcomes that delivered sustainable results for our shareholders. This required us to differentiate our payouts to reward high-performing employees for their contributions across Janus Henderson as we continue working to transform our business. Accordingly, with respect to the variable compensation levels of our NEOs in 2023:

■ We increased our CEO’s variable compensation based on our favorable stock performance during the year, his considerable contributions to our transformation during his first 18 months as CEO, his performance, and continued growth in the role. The Board believes he is the right CEO to lead this company and the compensation accurately reflects the strategic leadership he provides.

■ While we increased our CEO’s variable compensation, it is important to note that the majority of his pay remains strongly aligned with our longer-term performance. 70% of his incentive compensation deferred into equity, of which 60% was delivered in long-term performance-based share units (“PSUs”) and remains at-risk.

■ For our other NEOs, average variable compensation declined reflecting our operating performance.

Additional details on the Committee’s 2023 compensation decisions for our NEOs can be found on page 43 of this CD&A.

* Net flows exclude Intech, the sale of which was completed March 31, 2022.

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 36

Overview of our Compensation Program

Our program is heavily weighted towards long-term equity incentives and significantly linked to at-risk and performance-based compensation, particularly for our CEO and our other NEOs. We believe that these awards better align our programs with the interests of our shareholders.

The revisions to our 2022 compensation framework received overwhelming support during our shareholder outreach engagements during the year, and we therefore continued these practices in 2023:

■ Continued the use of quantitative and qualitative measures in our scorecard to align variable compensation with Company and individual performance designed to assess financial, client, strategic, and cultural outcomes.

■ Delivered a significant percentage of our variable compensation to our NEOs in long-term, stock-based incentive compensation. For the CEO, 70% of 2023 variable compensation was awarded as long-term incentive awards (“LTI”). For our other NEOs, 60% of 2023 variable compensation was awarded as LTI.

■ Delivered a significant percentage of our LTI in PSUs. For the CEO, the Committee lowered the percentage of LTI awarded in PSUs to 60% (from 70% in 2022) to better align with market practice. For our other NEOs (except our Chief Risk Officer), 50% of their LTI remained awarded in PSUs.

■ We used the same core PSU design for our 2024 - 2026 PSU grants. The PSUs are eligible to vest after three years. The number of shares vesting is based on achievement of annual net new revenue growth and adjusted operating margin. We added relative TSR and net flow modifiers to reward relative outperformance during the performance period. The Committee believes these metrics align best with shareholder outcomes.

Shareholder Engagement

The Company and the Committee view engagement with our shareholders as a top priority and we value shareholder feedback related to our compensation program. This feedback is shared with the Committee and is given significant consideration during the annual review of our program. Last year, shareholders were broadly supportive of our approach to executive compensation as demonstrated by our say-on-pay proposal vote (78.1% in favor) at the 2023 Annual Meeting. However, this was a decline relative to the support we received in 2022 (92.4% in favor). Based on discussions with our shareholders, this decline in support was associated with the one-time transition awards determined by the prior Committee in 2021 to be appropriate to reinforce leadership stability following the former CEO’s retirement. Since the change in Committee leadership, no special awards have been granted or are under consideration for the NEOs.

During 2023, we reached out to our top 15 shareholders, representing 71% of our shares outstanding, and we engaged with all of those who expressed an interest in providing feedback. The feedback we received from our shareholder outreach efforts included support for the following:

■ The design of the executive compensation program implemented last year, most notably awarding a significant portion of our variable compensation awarded in long-term PSUs.

■ The strategy framework implemented by our new Chief Executive Officer.

■ The recent Board refresh and governance oversight, including decision-making around compensation.

In Summary

On behalf of your Board of Directors we would like to thank you for your support of Janus Henderson Group. We are committed to a compensation program that pays for performance, aligns with ongoing shareholder interests, and motivates our leadership team as we continue to deliver value to our shareholders and navigate challenging market conditions.

We thank you again for your feedback and respectfully ask for your continued support at our 2024 Annual Meeting.

Sincerely,

Alison Quirk

Compensation Principles

The Committee oversees our overall compensation program for Company employees. In terms of executive compensation, the Committee is responsible for the program’s overall design, the review and approval of goals and objectives relevant to our CEO’s performance assessment and compensation decisions, and approval of the compensation of our executive officers based on an evaluation of each executive’s performance. Our executive compensation program is designed to:

■ Attract and retain highly-skilled individuals critical to our long-term success;

■ Fully align pay with our strategic priorities and reinforce a strong performance culture through rewards that reflect Company-wide, department, team, and individual performance;

■ Align management, client, and shareholder interests, deferring a significant portion of compensation into JHG stock awards;

■ Manage risk-taking and conflicts of interest in our incentive plans, maintaining an appropriate balance between base salary, short-term cash incentives, and long-term deferred incentives; and

■ Ensure that compensation processes and procedures comply with regulatory requirements, are consistent with market practice, and include effective risk management controls.

2023 Company Highlights

After difficult market returns in 2022, most global markets experienced growth in 2023 as external economic concerns in early 2023 were overshadowed by decreasing inflation and the expectation of the end of interest rate hikes as the year progressed.

Net outflows of $(0.7) billion in 2023 were markedly improved compared to $(30.8) billion of net outflows in 2022 (excluding Intech, the sale of which was completed March 31, 2022). Adjusted operating margin declined compared to 2022. Long-term investment performance remains solid with 60%, 69%, and 71% of assets outperforming benchmarks on a three-, five-, and ten-year basis. Our cash flow generation and strong balance sheet continue to provide us with flexibility to invest in the business—both organically and inorganically—and return cash to shareholders. We continue to focus on our mission of helping clients define and achieve superior financial outcomes through differentiated insights, disciplined investments, and world-class service. Financial results, net flows, investment performance, and several highlights are described below.

Financial Outcomes

Total Shareholder Return (“TSR”)

TSR for JHG in 2023 was 36.0%, compared to a median TSR of 11.1% for the JHG Peer Group (as defined on page 47), 31.4% for the S&P US BMI Asset Management & Custody Banks Index, and 26.3% for the S&P 500. The TSR comparison reflects stock price appreciation during the year and assumes reinvestment of dividends, if any.

Adjusted Revenue*

A 5% decrease in average AUM led to a 3% decrease in adjusted revenue for the year to $1,646 million from $1,705 million in 2022.

Adjusted Operating Margin* (%)

 

Adjusted operating margin of 30.9% decreased 2.9 percentage points from 33.8% in 2022. 

Net Flows

 

Net outflows of $0.7 billion improved significantly compared to 2022 net outflows of $30.8 billion.

* In addition to financial results reported in accordance with GAAP, we report certain financial measures on a non-GAAP basis. These measures are not in accordance with, or a substitute for, GAAP, and our financial measures may differ from the non-GAAP financial measures used by other companies. For additional information, see Annex A, “Reconciliation of Non-GAAP Financial Measures.”

Strategy Progress

We are in the execution phase of our strategic vision that was established during 2022 and our progress is starting to bear fruit. We believe our strategy will lead to consistent organic revenue growth over time. Our three strategic pillars are described below.

■ Protect and Grow our core businesses – We have identified existing opportunities to better align resources to protect and grow our core business.

■ Amplify strengths not fully leveraged – Our research, portfolio management, and client service strengths can be amplified with adjacent products, channels, geographies, and vehicles.

■ Diversify where clients give us the right to win – We have identified significant white spaces in asset management where we can have the right to win, whether that is by filling gaps in Investment teams or capabilities, or within channels or regions.

In connection with our Protect and Grow strategy, 2023 US Intermediary net flows were positive for the first time since 2016 resulting in 1% organic growth, and we are capturing market share in this strategically important market. Under our Amplify strategy, net inflows into our suite of active ETFs was $6 billion and AUM more than doubled to $12 billion. With this growth, Janus Henderson is now the fourth largest provider of active fixed income ETFs in the US. We extended several strategies into new vehicles, including ETFs, Open-Ended Investment Company (“OEIC”), Société d’investissement à Capital Variable (“SICAV”), and Separately Managed Account (“SMA”). Under our Diversify strategy, we announced a joint venture, Privacore, that looks to take advantage of the democratization of private alternatives into the retail channel, and we continue to look actively to buy, build, or partner.

Mission, Values, and Purpose

During 2023, we reinforced our culture through articulating our Mission, Values, and Purpose (“MVP”) company wide. It defines who we are and what we stand for as a collection of individuals and a Company, not just for today, but in the future. Our MVP, coupled with our strategy and a foundation of creating fuel for growth, guides our decision-making and prioritization, and it empowers our employees to move together in the same direction to help us succeed in this competitive landscape.

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 39

Fuel for Growth

Our philosophy has always been to maintain strong financial discipline and invest in the business where it strategically makes sense while looking to operate more efficiently to provide the “fuel for growth”. This fuel for growth, which allows for reinvestment in Janus Henderson’s strategic initiatives on behalf of our clients, was realized at a faster pace than expected and at a higher dollar amount. We obtained cost efficiencies better than target by the end of 2023 and continue to entrench a strategic cost management mindset across all departments.

Alignment of Pay and Performance

For our CEO and other NEOs, the Committee uses a structured scorecard to evaluate performance and determine total variable compensation on an annual basis. The scorecard approach is designed to reflect the Board’s expectations of leadership and to ensure executives are rewarded for strong Company performance and value creation for our shareholders over the long term. The Board believes that strategy and culture are critical foundations to creating client, employee, and shareholder value.

The specific performance measures included in the scorecard are the same measures we use to evaluate our business. The performance categories, measures, and weightings used in the 2023 scorecard include the following:

■ Financial Outcomes (25% weighting). Deliver strong financial results for shareholders measured by revenue growth, cost management, operating margin expansion, and TSR.

■ Client Outcomes (25% weighting). Deliver superior investment performance and client service as measured by investment performance relative to benchmark over various time periods, client satisfaction, and net AUM flows.

■ Strategy (25% weighting). Transform and articulate the Company’s strategy to position the organization for growth.

■ Culture (25% weighting). Embed new Mission, Values, and Purpose, create a high-performance culture focused on delivering positive client outcomes, attract and retain diverse talent, drive cross-functional collaboration and communication, and reinforce our commitment to Corporate Responsibility.

After the end of each year, the Committee uses the scorecard to evaluate the CEO’s performance relative to the specific performance measures established at the beginning of the year. Following this assessment, the Committee determines the total variable compensation award for the CEO. This same scorecard approach is used by the CEO to evaluate the performance of our other NEOs. The CEO recommends total variable compensation awards to the Committee for consideration, which then makes the determination.

Once the amount of total variable compensation is determined, it is apportioned into short-term incentives (“STI”), such as cash bonuses, and deferrals into LTIs, including time-vested restricted stock units (“RSUs”) and PSUs.

CEO and Other NEO Total Variable Compensation Mix

■ For our CEO, 70% of 2023 variable compensation is deferred into LTI, with 60% of the LTI granted in PSUs to better align with market practice, versus 70% granted in PSUs in 2022.

■ For the other NEOs, 60% of 2023 variable compensation is deferred into LTI, and 50% of the LTI is granted in PSUs, consistent with 2022 (with the exception of Ms. Fogo who receives 100% of the LTI granted in RSUs as the Chief Risk Officer).

Time-vested RSUs vest in equal installments over a three-year period. Performance-vested PSUs cliff vest on the third anniversary of the grant date using a matrix-based target, measured at the end of the three-year period, derived by a combination of annual net new revenue growth and adjusted operating margin* with TSR and net flow modifiers. The Committee believes the PSU vesting targets have a strong correlation to relative shareholder returns and align to performance measures that management can directly influence.

* In addition to financial results reported in accordance with GAAP, we report certain financial measures on a non-GAAP basis. These measures are not in accordance with, or a substitute for, GAAP, and our financial measures may differ from the non-GAAP financial measures used by other companies. For additional information, see Annex A, “Reconciliation of Non-GAAP Financial Measures.”

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 40

The scorecard approach used to determine total variable compensation each year, combined with the rigorous PSU vesting conditions, are intended to ensure CEO and other NEO variable compensation is aligned with shareholder interests and linked to performance over the long term.

■ To receive a variable compensation award, executives must first deliver results against the performance measures as outlined in the scorecard; and

■ PSUs are eligible to vest after three years. The number of shares vesting is based on achievement of annual net new revenue growth and adjusted operating margin modified by relative TSR and net flow numbers at the end of the three-year performance period.

These performance measures reinforce the Committee’s dedication to pay-for-performance, establishing rigorous performance standards, and align executive pay with shareholder interests over the short and long term.

Elements of Compensation

The Committee emphasizes performance-based variable incentives as the primary element of compensation paid to our CEO and other NEOs, reinforcing our strong pay-for-performance culture. In the 2023 performance year, 93% of CEO total compensation and 80% of other NEO total compensation consisted of performance-based variable incentives.

The charts below illustrate the mix of total compensation awarded in respect of the 2023 performance year. Total compensation includes base salary plus total variable compensation delivered in the form of STI, such as cash bonuses, and deferrals into LTI, including time-vested RSUs and performance-vested PSUs.

We strive to maintain competitive compensation and benefits for all employees at the Company. Compensation, including an appropriate balance of base salary and variable compensation, is designed to attract and retain highly-skilled and diverse talent, reinforce a strong pay-for-performance culture, and align the interests of management with our clients and shareholders. The table below provides further detail regarding compensation and benefits at Janus Henderson.

Component	Purpose	Pay Type	Pay Element	Details
Base Salary	Provides fixed pay for performing day-to-day job responsibilities	Fixed	Cash	• Constitutes a small portion of total annual compensation. • Reviewed periodically to maintain market competitiveness. • Provides market competitive base salary reflective of the responsibilities and scope of the position, as well as the experience and caliber of our executive talent.

		Long-Term Incentive	Time-Based Restricted Stock Units	A portion of total variable compensation is deferred into RSUs which are typically subject to a three-year ratable, time-based vesting schedule. Cash dividend equivalents are paid on unvested RSUs and are included in taxable compensation.
			Performance-Based Share Units	A portion of total variable compensation is also deferred into PSUs, which are eligible to vest after three years. The number of shares vesting is based on achievement of annual net new revenue growth and adjusted operating margin modified by relative TSR and net flow numbers at the end of the three-year performance period.

2023 Compensation for the CEO and Other NEOs

2023 CEO Variable Compensation

In establishing Mr. Dibadj’s 2023 compensation package, the Committee reviewed a range of information, including key objectives in four categories: (1) Financial Outcomes, (2) Client Outcomes, (3) Strategy, and (4) Culture. Competitive benchmarking data provided by the Committee’s independent compensation consultant, CEO compensation packages disclosed by other public financial services firms, and insights from shareholders and external advisors were also considered in determining his 2023 compensation. Mr. Dibadj’s total compensation of $11.0 million payable for 2023 is comprised of base salary and performance-based variable compensation with a larger portion of our compensation package delivered in PSUs relative to peers.

The Committee used the scorecard approach to assess Mr. Dibadj’s performance. A summary of Mr. Dibadj’s 2023 compensation and scorecard assessment are set forth below.

Ali Dibadj | Chief Executive Officer
		Responsibilities Mr. Dibadj is the Chief Executive Officer and serves as a member of our Board of Directors. He is responsible for the strategic direction and overall day-to-day management of the Company and leads the Executive Committee.
2023 Compensation (in 000s)
Base Salary	$725
Performance-Based Variable Compensation
Annual Cash Bonus	$3,083
JHG Restricted Stock (“RSUs”)	$2,877
Performance-Based Share Units (“PSUs”)	$4,315
Total Variable Compensation	$10,275
Total Annual Compensation	$11,000

Compensation Decisions for Mr. Dibadj

The Committee approved $10.275 million in total variable compensation for Mr. Dibadj. His compensation increased 19% over 2022, which was his first and partial year as Chief Executive Officer, and was part of his new hire package. In 2023, under Mr. Dibadj’s leadership, the Company experienced annual net revenue growth that exceeded targets, improved asset retention rates, strong TSR on JHG common stock, and continued improvements on strategic and cultural initiatives. Based on this strong annual performance, including executing on the Company’s vision and driving financial outcomes, the Committee determined that an increase in Mr. Dibadj’s compensation was warranted to bring his total compensation in line with market median of our US peers.

2023 CEO Scorecard Outcomes

Financial Outcomes (25% weighting)

Despite a challenging and competitive year for the asset management industry, Janus Henderson surpassed its growth targets and delivered positive shareholder returns which reflects the success of its long-term strategic direction and commitment to client service that Mr. Dibadj oversees.

■ Mr. Dibadj led the Company’s efforts in exceeding its annual net new revenue growth target for the year with a strong balance sheet that continues to provide the Company flexibility to invest in the business, both organically and inorganically, and to return cash to shareholders.

■ TSR for JHG common stock in 2023 was +36.0% compared to the median TSR of +11.1% for the JHG Peer Group, +31.4% for the S&P US BMI Asset Management & Custody Banks Index, and +26.3% for the S&P 500 Index (returns of both indices were also calculated on a total return basis).

■ Cost-saving targets were exceeded for the year after an extensive review of operating expenses, including both compensation and non-compensation related expenses.

Client Outcomes (25% weighting)

The Company’s investment performance remained solid, reinforced by Mr. Dibadj’s significant commitment to client engagement, fostering client interactions to build trust, and showcase new products.

■ The majority of our assets under management outperformed their respective benchmarks over the three- and five-year periods ended December 31, 2023, despite a challenging market environment. The Company also saw an improvement in asset retention year-over-year.

■ Worked with our newly appointed Chief Responsibility Officer in advancing the Company’s long-term goal of integrating financially material ESG consderations into appropriate strategies (e.g., excluding passive and enhaced index strategies). As of December 31, 2023, the majority of our assets under management were ESG-integrated.

Strategy (25% weighting)

During the past 18 months, Mr. Dibadj has launched and continued to drive the success of the strategic framework aligned to the Company’s three-pillar strategy of Protect and Grow, Amplify, and Diversify, which has already led to actionable business opportunities and expected long-term revenue growth.

■ Made signficant progress toward the delivery of nine strategic initiatives across our key target client segments which are aligned to the Company’s three-pillar strategy of Protect and Grow, Amplify, and Diversify.

■ Successfully formed a joint venture partnership with Privacore, an open-architecture distributor and trusted consultant for alternative investment products tailored to Private Wealth clients, to provide new avenues to diversify our revenue streams. The firm is expected to become fully operational in the first quarter of 2024.

Mr. Dibadj continues to position the Company for growth by leveraging the strength of the existing cultural foundation with a refined strategy of focused execution and increased collaboration and accountability.

2023 Compensation for Other NEOs

The Committee is responsible for oversight and approval of compensation paid to the other NEOs who are eligible to receive total variable compensation awards from the Company. The scorecard approach for our other NEOs includes the same categories, measures, and outcome weightings as the CEO scorecard described above.

The CEO, in conjunction with the Committee, agreed to apply the same scorecard approach to our other NEOs to drive individual accountability and alignment between Company and business unit outcomes, and to strengthen the link between compensation and performance over the long term. At the end of the year, each of the other NEOs completes a self-assessment, and the CEO uses the scorecard approach to evaluate their performance on a Company, department, and individual level. He then recommends total variable compensation awards for each other NEO to the Committee for consideration.

In determining total variable compensation for the other NEOs, the CEO and the Committee consider:

■ other NEO performance based on the scorecard approach;

■ demonstration of certain behavioral competencies included in the self-assessment;

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 43

■ competitive benchmarking data for similar roles as compared to the JHG Peer Group; and

■ the direction of the Company profit pool, which is funded based on Company profits.

In general, total variable compensation awards to the other NEOs are directionally consistent with the variable compensation awards paid to all employees from the profit pool.

Total annual compensation and performance against the scorecard measures for the other NEOs for the 2023 performance period is summarized below.

The Compensation Process

JHG Peer Group

The Committee, with assistance from its independent compensation consultant, periodically reviews the composition of our peer group to ensure that it continues to serve as an appropriate market reference for executive compensation purposes. In reviewing the composition of our peer group, the Committee considers various factors, including our revenue, total AUM, and business model as compared to a select group of companies in our industry.

The Committee does not determine executive pay levels solely based on those of the JHG Peer Group (the “JHG Peer Group,” as shown below). Rather, the Committee uses data from the JHG Peer Group as one of multiple reasonable reference points for consideration when determining NEO pay. The Committee believes that reference to the JHG Peer Group is useful to ensure that NEO variable compensation is competitive relative to compensation levels at other asset management firms with which we compete for executive talent.

Below is the compensation peer group that we used for 2023:

JHG PEER GROUP
•  Abrdn plc •  Affiliated Managers Group, Inc. •  AllianceBernstein Holding LP •  Ameriprise Financial, Inc. •  Artisan Partners Asset Management, Inc. •  Cohen & Steers, Inc.	•  Federated Hermes, Inc. •  Franklin Resources, Inc. •  Invesco Ltd. •  Lazard Ltd. •  M&G plc	•  Man Group plc •  Schroders plc •  T. Rowe Price Group, Inc. •  Victory Capital Holdings, Inc. •  Virtus Investment Partners, Inc.

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 47

Role of the Independent Compensation Consultant

The Committee has the sole authority to retain and terminate any compensation consulting firm directly assisting it in the evaluation of director or executive compensation. The Committee also has the sole authority to approve fees and other retention terms for its consultant.

The Committee retains Meridian Compensation Partners (“Meridian”) as its independent compensation consultant to provide objective analyses of, and counsel on, our executive compensation program and practices during the year. Throughout the year, the independent consultant is asked to review and comment objectively on management proposals and presentations to the Human Capital and Compensation Committee covering all elements of compensation paid to the NEOs, including an evaluation of the market competitiveness of our executive compensation packages, an assessment of pay in relation to performance, and input into CEO and other executive pay designs. The independent consultant also provides counsel on general market trends and technical developments, as well as input on the amount and structure of pay for the non-executive directors serving on our Board. The independent consultant is required, on an annual basis and upon the reasonable request of the Committee, to report to the Committee on any consulting services performed for management and their related fees. There were no such services provided to management during 2023.

The Committee recognizes that it is essential to receive objective advice from compensation consultants that are independent. In assessing Meridian’s independence, the Committee considered the independence factors for compensations consultants listed in the NYSE listing requirements and determined that there were no conflicts of interest.

Shareholder Outreach

Our executive compensation and other governance matters are informed by shareholder feedback. In 2023, 78.1% of our shareholders supported the Company’s advisory say-on-pay proposal. During 2023, we reached out to our top 15 shareholders, representing 71% of our shares outstanding in 2023, to discuss governance matters, including our executive compensation program, and we engaged with all those who expressed an interest in providing feedback. The feedback we received was broadly supportive of the design of the executive compensation program implemented last year.

Compensation Risk Assessment

On an annual basis, the Company undertakes an assessment of existing compensation programs and practices, including the material terms of our compensation plans, design elements that could potentially encourage excessive risk-taking or are reasonably likely to have a material adverse impact on the Company, and any risk mitigation features in place. The Committee receives the results of this assessment for its review and consideration.

In 2023, the Committee concluded that the Company’s compensation programs and practices discourage excessive risk-taking due to the mix of fixed and variable compensation, use of deferred incentives (including both RSUs and PSUs), and the Committee’s ability to claw back both deferred and previously paid awards.

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 48

Other Compensation Policies

We are committed to ensuring that our executive compensation program and practices reflect principles of good governance as demonstrated by the following key aspects comprising our program and by those practices that we do not engage in.

What We Do		What We Don’t Do
	Incorporate sound risk management and risk avoidance in our incentive plan design, including robust Board and management processes to identify and monitor risk		No change-in-control agreements or single-trigger vesting of award in connection with a change in control of the Company
	Significant majority of NEO compensation is at-risk (93% for the CEO, 80% for other NEOs)		No gross-ups for potential excise taxes
	At least 60% of our NEOs’ total variable compensation consists of long-term incentive awards		No dividends or dividend equivalents paid on unvested or unearned PSUs
	60% of CEO equity awards granted as PSUs, with vesting contingent on a further three-year performance period		No automatic acceleration of vesting on long-term incentive awards on termination of employment, except upon death
	Robust stock ownership guidelines (10x base salary for CEO and 3x for other NEOs)		No short selling, hedging, or pledging of JHG shares
	Regularly review the governance of our programs and revise to align with market best practices		No special executive retirement pension benefits
	Active shareholder engagement program to seek and incorporate feedback		No excessive perquisites
	Malus and clawback policies require us to recapture long-term incentive awards paid to an executive who engages in financial misconduct (including the misstatement of financial results)		No decisions made solely based on market data
			No encouragement of excessive risk-taking

Stock Ownership Guidelines

To ensure our NEOs and other executive officers make a meaningful investment in our common stock to align their economic interests more closely with those of other shareholders, the Committee has set minimum stock ownership guidelines for non-executive directors and members of the Company’s Executive Committee. We believe this commitment to stock ownership will continue to play a significant role in driving our success and creating long-term value, further aligning our senior leaders’ interests with those of our shareholders. Guideline levels are phased in over a period of five years. Shares that count towards this ownership guideline include shares of our common stock owned directly and common stock equivalents (PSUs are excluded). The CEO, other NEOs, and other Executive Committee members must meet these requirements within five years of becoming subject to the ownership requirement. Executives subject to the foregoing guidelines are not permitted to sell shares of our common stock until they have met the applicable ownership guidelines. All our NEOs have satisfied the applicable stock ownership guidelines or are expected to meet the guideline by the conclusion of the five-year time period.

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 49

Hedging and Pledging

Our Share Trading Policy prohibits our employees and directors from engaging in hedging designed to offset or reduce the risk of price fluctuations in our common stock or any other transactions that include the use of derivatives (including contracts for difference, spread betting, prepaid variable forward contracts, equity swaps, collars, or exchange funds) in relation to our common stock or similar transactions with respect to our common stock that would allow them to continue to own the securities without the full risks and rewards of ownership.

In addition, our Share Trading Policy prohibits our employees and directors from trading in options, warrants, puts, calls, and similar instruments linked to the value of our securities. Given the relatively short term of publicly traded options, transactions in options may create the appearance that an employee or director is trading based on material non-public information and focus attention on short-term performance at the expense of the Company’s long-term objectives.

Our directors and employees are also prohibited from engaging in short sales of our common stock. Short sales may reduce a seller’s incentive to seek to improve the Company’s performance and often have the potential to signal to the market that the seller lacks confidence in our prospects. In addition, Section 16(c) of the Exchange Act prohibits officers and directors from engaging in short sales of our common stock.

Because a margin sale or foreclosure sale could occur at a time when the holder is aware of material non-public information or otherwise is not permitted to trade in JHG common stock, our Share Trading Policy prohibits employees and directors from holding shares of our common stock in a margin account or otherwise pledging our stock as collateral for a loan.

Certain aspects of this policy do not apply to Trian Fund Management, L.P. and its affiliates, including the funds and investment vehicles managed by Trian. Trian is our largest shareholder and an institutional investment manager with which two of our non-executive directors – Brian Baldwin and Josh Frank – are affiliated. Mr. Baldwin is Head of Research and a Partner of Trian and Mr. Frank is Co-Chief Investment Officer and a Partner of Trian. However, our Share Trading Policy applies to each of Mr. Baldwin and Mr. Frank in his individual capacity.

Clawback

The Company maintains a clawback policy applicable to long-term incentive awards, including equity-based compensation, granted to our NEOs on or after January 1, 2020, to the extent such individuals were NEOs at the time of grant. Upon a breach of the policy, the Committee (or the Board) may cause such awards to be forfeited or, in the case of previously settled or paid awards, clawed back. The policy applies under the following circumstances: (i) if the NEO is found to have engaged in certain types of material misconduct, (ii) in case of certain situations involving a material misrepresentation (regardless of whether the NEO’s actions caused the misrepresentation) in relation to the financial performance of the Company, its subsidiaries, business units, funds or other investment vehicles managed by a member of the Company group, including upon a misstatement of financial results or other errors or discrepancies, or relating to the performance of the NEO, which formed the basis of certain incentive compensation determinations, (iii) upon significant changes in the overall financial situation of the Company group, and (iv) upon a material failure of risk management.

In addition, in 2023 the Company adopted an additional Clawback Policy for Executive Officers in order to comply with newly effective rules promulgated under the Dodd-Frank Act and NYSE listing standards. This policy applies to all incentive-based compensation (including cash bonus payments) received by our current and former Section 16 officers on or after October 2, 2023, the effective date specified in the NYSE listing standards. Under this policy, “incentive-based compensation” means any compensation that is granted, earned, or vested based wholly or in part upon the attainment of a financial reporting measure. In the event of an accounting restatement that impacts the financial reporting measures on which incentive-based compensation is calculated, this policy will require the clawback of the amount by which the compensation actually received exceeds the amount that otherwise would have been received based on the restated financial results.

EXECUTIVE COMPENSATION TABLES

Summary Compensation Table for Fiscal Year 2023

The Summary Compensation Table below provides information regarding compensation during the years ended December 31, 2023, 2022, and 2021 for each of our NEOs. The information presented in this table differs from the compensation information presented in the “2023 Compensation for the CEO and Other NEOs” section of the CD&A for the following reasons:

■ The CD&A describes compensation decisions made with respect to the 2023 performance year, regardless of when such compensation was actually paid or granted.

■ By contrast and as required by SEC rules, the Summary Compensation Table reports LTI awards in the calendar year in which they were granted. Our annual LTI awards relating to each performance year are granted shortly after year-end. Therefore, in accordance with SEC rules:

■ LTI awards determined based on 2022 performance and granted in 2023 are included in 2023 compensation in the Summary Compensation Table below.

■ LTI awards determined based on 2023 performance and granted in 2024 will be included in 2024 compensation in next year’s Summary Compensation Table.

In accordance with SEC rules, compensation shown in the Summary Compensation Table below includes not only cash compensation awarded for services in the applicable year but, in the case of LTI awards granted in the years reported in the table, compensation awarded for performance in prior years and forward-looking performance-vested compensation.

(1)	Compensation for Messrs. Thompson and Lowry and Ms. Fogo was paid in GBP and has been converted to USD using the average annual exchange rate for the applicable year (for 2023, 1 GBP = 1.2429 USD). Exchange rate differences account for the varying salaries shown for Mr. Thompson and Ms. Fogo from year to year.
(2)	Amounts in this column represent the portion of the annual performance-year bonus paid in cash for the respective fiscal year, as reported in the CEO and other NEO performance descriptions in the “Compensation Discussion and Analysis” section above.
(3)	In accordance with SEC rules, the amounts in this column for 2023 are the aggregate grant date fair values of the RSUs and PSUs granted during 2023, even though the value awarded was based on 2022 performance. The aggregate grant date fair values of the awards shown in this column are computed in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718 (ASC 718). The assumptions made, if any, when calculating the amounts in this column are found in Note 15 to the Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023. The amounts reported in the Summary Compensation Table for the PSUs are the values at the grant date as determined in accordance with ASC 718, which take into account the probable outcome of the performance conditions. Consequently, these values differ from the nominal amounts of the awards made by the Committee, which are divided by the Company’s common stock price as determined on the grant date to yield a target number of PSUs.
(4)	In accordance with SEC rules, the amounts in this column for 2023 represent fund unit awards vesting in 2023 based on the cash value of such awards at the time of vesting (which includes any appreciation in the funds in which the awards were nominally invested following the grant date) even where performance related to prior years. SEC rules require the presentation of such awards that vested during calendar year 2023, not awards made in respect of performance in 2023.

(b)

Amounts in this column represent, where applicable, Company matching charitable contributions under the Janus Henderson Matching Gift programs. For Mr. Dibadj, the amount shown includes tax equalization on foreign tax which is in accordance with the Company’s Tax Equalization policy that applies to all applicable employees. This policy aims to ensure that regardless of location, an employee on a job-related assignment away from their home country should not be worse off had they continued to work for the Company in their home country.

Grants of Plan-Based Awards for Fiscal Year 2023

The table below shows the non-equity incentive and equity award opportunities granted to our NEOs in 2023. These awards were based on 2022 performance and funded from the 2022 total incentive pool.

(1)	Represents the number of PSUs granted in 2023 assuming target performance. The 2023 PSUs vest at the end of the performance period using a matrix-based target, measured at the end of the three-year period, derived from a combination of annual net new revenue growth and adjusted operating margin. There is no guaranteed minimum payment under our plan. More detailed information about the terms of these awards appears on page 41.
(2)	Represents the number of RSUs granted in 2023 in respect of 2022 performance. The 2023 RSUs are eligible to vest ratably over the three-year period after the grant date, generally subject to continued service. More detailed information about the terms of these awards appears on page 41.
(3)	The assumptions used in determining grant date fair value are the same as those set forth in footnote 3 to the Summary Compensation Table. These amounts do not necessarily represent the actual value that may be realized by the NEO.

Potential Payments Upon Termination or Change-in-Control

Service Agreements with Executive Officers

In addition, the Company will provide Mr. Dibadj with 18 months of continued health and welfare coverage. The Severance Rights Agreement further provides that any unvested time- or performance-based restricted stock units held by Mr. Dibadj will remain outstanding and will continue to vest in accordance with their terms. The foregoing severance entitlements are subject to the execution of a general release of claims in favor of the Company and continued compliance with post-termination restrictive covenants, including 12 months’ non-competition and non-solicitation of clients, employees, and contractors.

In addition to the arrangements with Mr. Dibadj, we remain party to a service agreement with Mr. Thompson that was entered into prior to the merger of Janus Capital Group Inc. and Henderson Group plc in 2017, and we entered into a service agreement with Ms. Fogo on March 15, 2018, at the time of hire. Mr. Thompson’s service agreement provides for his employment to continue until terminated by Mr. Thompson on six months’ notice or by the Company on 12 months’ notice. Ms. Fogo’s service agreement provides for her employment to continue until terminated by either party with six months’ notice. In each case, during the notice period, the Company may place Mr. Thompson and Ms. Fogo on garden leave for up to six months with full salary and benefits.

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 55

The tables below describe the potential termination payments for our currently employed NEOs under various termination of employment scenarios. Post-termination compensation and benefits paid to our NEOs are typically addressed by the plan or award agreement relating to each element of compensation. For purposes of estimating the compensation and benefits that would apply to our NEOs, these amounts have been calculated as if each NEO’s employment had been terminated as of December 31, 2023, using the closing value of our common stock on December 29, 2023 ($30.15 per share).

The numbers disclosed in the tables are calculated in USD and are subject to other estimates and assumptions, therefore, the actual amounts the NEO may receive may differ materially from those shown in these tables. Additional information on the calculations for any payments are outlined in the footnotes of each table.

Voluntary Resignation

Upon a voluntary resignation (not constituting a retirement), no NEO is entitled to any compensation or benefit and any unvested LTI awards, including fund unit awards and stock options under the Sharesave program (a UK tax approved plan), will forfeit.

Involuntary Termination

Upon an involuntary termination of employment without cause, the CEO will be entitled to severance in accordance with his Severance Rights Agreement. Payments would include:

■ A lump sum amount equal to three times annual total cash compensation,

■ Any unpaid portion of variable cash compensation from a completed fiscal year,

■ A cash payment equal to the determined cash bonus for the year of termination, prorated through the date of termination,

■ Any unvested LTI awards, including PSUs, would continue to vest subject to achievement of performance criteria, and

■ A cash payment equal to the value of continued benefits for a period of 18 months following date of termination.

Except with respect to Mr. Dibadj, our NEOs will not be entitled to severance in the event of an involuntary termination of employment that is not the result of a role elimination. In the unlikely event that the Company were to eliminate the role of an NEO, he or she would be entitled to the severance benefits in place at the time of the role elimination, and consistent with the severance benefits offered to all other employees in the event of a role elimination. If the termination had occurred on December 31, 2023, severance payments would include:

■ A cash payment equal to a number of months of base salary (determined by tenure), and subject to a minimum of three and a maximum of 12 months,

■ A payment in lieu of notice, if applicable, as described in the service agreements with certain NEOs,

■ A pro-rata portion of total variable compensation based on the previous year’s actual variable compensation (assuming termination after July 1),

■ Any unvested LTI awards including fund unit awards would continue to vest, and he or she will have six months following termination of employment to exercise any stock options under the Company’s Sharesave program (a UK tax approved plan), and

■ Where applicable, a cash payment equal to the value of continued benefits (determined by tenure), and subject to a minimum of three and a maximum of 12 months.

Death, Disability, or Retirement

If an NEO’s employment is terminated due to death or disability, unvested LTI awards including fund unit awards will vest.

If an NEO meets the age and service requirements of retirement or qualifies for retirement following an assessment of the Company’s retirement criteria, his or her unvested LTI awards shall continue to vest subject to certification of the terms of the award agreements.

Change-in-Control

The Company is not party to any individual change-in-control agreements with any of the NEOs. In addition, beginning with LTI incentive grants made in 2020, LTI incentive awards including fund unit awards do not contain change-in-control provisions.

Pay Versus Performance Table for Fiscal Year 2023

The Pay Versus Performance Table below discloses the relationship between the compensation actually paid (“CAP”) to the executive officers and the Company’s financial performance during the years ended December 31, 2020, 2021, 2022, and 2023. The compensation information presented in this table is different from compensation information presented in the CD&A and in the Summary Compensation Table above. The differences can largely be attributed to variation in the treatment of stock awards in each of these tables as described in greater detail below.

■ The compensation presented in the “2023 Compensation for the CEO and Other NEOs” section of the CD&A illustrates compensation paid or granted to NEOs based on their performance during the 2023 performance period as determined by the scorecard approach. The stock awards shown as “JHG RSUs” and “JHG PSUs” in these tables include the portions of 2023 total variable compensation that will be deferred into JHG RSUs and JHG PSUs when they are granted in February 2024.

■ In accordance with SEC rules, the Stock Awards column in the Summary Compensation Table includes the aggregate grant date fair values of the RSUs and PSUs granted during 2023, even though the number of RSUs and PSUs granted was determined based on the 2022 performance of the executive officers.

■ The Pay Versus Performance Table below differs from both the information presented in the CD&A and in the Summary Compensation Table, because it calculates actual compensation based on different methodologies, including the value of outstanding unvested stock awards as of December 31, 2023.

(iv)

2022 NEOs include: Mr. Thompson, Mses. Cain, Fogo, Rosenberg, and Tiphani Krueger, former Global Head of Human Resources. Mr. Thompson served as our Interim Chief Executive Officer from April 1, 2022, until Mr. Dibadj’s appointment on June 21, 2022. In connection with Mr. Thompson’s interim role, he continued to receive the same salary he received in 2022 for his role as Chief Financial Officer. Accordingly, Mr. Thompson’s 2022 compensation has been included in the average compensation column for our non-PEO NEOs.

(v) In 2021, the Compensation Committee considered the uncertainty caused by the former CEO’s retirement, combined with an increase in shareholder activism, and decided to grant one-time Transition Awards to each of the NEOs to reinforce leadership stability. Such awards were granted in February 2022 after the end of the 2021 performance year. An unintended consequence of this timing is that the Transition Awards are included in 2022 compensation, which could be interpreted to suggest that our NEOs received compensation increases for disappointing performance in 2022 rather than the performance year in which the value was determined.

(vi)	2021 NEOs include: Mr. Thompson, Mses. Cain, Fogo, and Rosenberg.
(vii)	2020 NEOs include: Mr. Thompson, Mses. Cain, Fogo, and Rosenberg.

(3)	The companies included in the peer group TSR calculations are the publicly traded companies included in the S&P US BMI Asset Management & Custody Banks Index used by the Company for purposes of disclosing our cumulative TSR in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023. The S&P US BMI Asset Management & Custody Banks Index is a market-value weighted index of 40 asset management companies.
(4)	In addition to financial results reported in accordance with GAAP, we report certain financial measures on a non-GAAP basis. These measures are not in accordance with, or a substitute for, GAAP, and our financial measures may differ from the non-GAAP financial measures used by other companies. For additional information, see Annex A, “Reconciliation of Non-GAAP Financial Measures”.
(5)	Adjusted operating margin is adjusted operating income divided by adjusted revenue for 2023. This measure has been designated as the “Company-Selected Measure” for 2023, in accordance with SEC rules, and represents the most important financial performance measure (that is not otherwise required to be disclosed in the table) used by the Company to link CAP to our NEOs in 2023.

Description of the Relationship Between Pay and Performance

Using the values reflected in the Pay Versus Performance table, below are graphical representations of the relationship for the last four fiscal years:

■ between the CAP to the PEO and each of the Company’s (x) TSR, (y) net income, and (z) the “Company-Selected Measure”;

■ between the average CAP to the other NEOs and each of the Company’s (x) TSR, (y) net income, and (z) the “Company-Selected Measure”; and

■ between the Company’s TSR and the TSR of the peer group for which disclosure is included in the Pay Versus Performance table.

Note:	The SEC requires companies to compare CAP to our NEOs (including the PEO) and net income, however, we do not rely on net income in the determination of NEO compensation.
(1)	The “CAP to PEO” amounts for 2023 and 2022 represent compensation paid to Ali Dibadj. “CAP to PEO” amounts for 2021 and 2020 represent compensation paid to Richard Weil.

Most Important Performance Measures to Determine Compensation Actually Paid

The four items below represent the most important performance measures we used to determine CAP to our NEOs in 2023, as described in the “Compensation Discussion and Analysis” section titled “2023 Compensation for the CEO and Other NEOs”.

Most Important Performance Measures

Adjusted Operating Margin

Annual Net New Revenue

Total Shareholder Return

% Assets Outperforming Benchmarks

CEO Pay Ratio Disclosure

As required by the Dodd-Frank Wall Street Reform and Consumer Protection Act and Regulation S-K of the Exchange Act, we are providing the following information about the relationship of the annual total compensation of Mr. Ali Dibadj, our CEO, and our employees (other than our CEO).

For 2023, our median employee was identified by calculating 2023 compensation for all employees, excluding our CEO, who were employed on December 31, 2023. All active employees were included, whether employed on a full-time or part-time basis. 2023 total compensation included base salary plus variable compensation (including sales commissions if applicable) before deferrals. Variable compensation was annualized for employees who were hired after the start of the 2023 fiscal year. Compensation to our non-US employees was converted to US dollars based on the average monthly exchange rates for the 2023 fiscal year.

Upon identifying the median employee, total compensation was calculated for this individual using the same methodology as used for the CEO (and other NEOs) in the Summary Compensation Table. Accordingly, our median employee’s 2023 annual total compensation was $150,994. In 2023, Mr. Dibadj had an annual total compensation of $10,113,098, as reflected in the Summary Compensation Table. As a result for 2023, the ratio of the annual total compensation of our CEO to the annual total compensation of our median employee (other than our CEO) was 67 to 1.

Compensation Committee Interlocks and Insider Participation

None of our executive officers currently serves as a member of the board of directors or as a member of a compensation committee of any other company that has an executive officer serving as a member of our Board or our Human Capital and Compensation Committee. None of the individuals who served on our Human Capital and Compensation Committee during 2023, and none of our current Human Capital and Compensation Committee members, are current or former officers or employees of the Company. Additionally, none of the individuals who currently serve as members of our Human Capital and Compensation Committee or who served as members of our Human Capital and Compensation Committee during 2023 has had any relationship requiring disclosure by the Company under Item 404 of Regulation S-K.

Equity Compensation Plan Information

The following table presents information, determined as of December 31, 2023, about outstanding awards and shares remaining available for issuance under our equity-based LTI plans:

Plan category	Number of securities to be issued upon exercise of outstanding options, warrants and rights (a)(#)			Weighted-average exercise price of outstanding options, warrants and rights ($)(b)			Number of securities remaining available for future issuance under equity compensation plans (excluding securities reflected in column (a)) (c)(#)
Equity compensation plans approved by shareholders		557,563	(1)		23.14	(2)		9,330,267	(3)
TOTAL		557,563			—			9,330,267

(1)	Includes awards outstanding under the Save as You Earn Plan and performance share units issued under the 2022 Deferred Incentive Plan to the CEO and certain Executive Committee members. There are an additional 3,928 options and 4,884,487 restricted stock units outstanding under the Company’s equity compensation plans, which are not included in column (a) because shares have been purchased on the open market to cover their issuance and such shares are therefore already reflected in the Company’s financial statements as currently outstanding shares of common stock.
(2)	The Save As You Earn Plan had 281,026 shares outstanding with a weighted average exercise price of $23.14 as of December 29, 2023. The performance share units are full value awards and do not have an exercise price, and, therefore, PSUs are not included in the weighted-average exercise price in column (b).
(3)	Includes shares remaining available for future issuance under the 2022 Deferred Incentive Plan as of December 31, 2023. None of the Company’s other shareholder-approved equity plans contain a specified share pool.

PROPOSAL 2
ADVISORY SAY-ON-PAY VOTE ON EXECUTIVE COMPENSATION

In accordance with Section 14A of the Exchange Act and the related SEC rules promulgated thereunder, we are asking our shareholders to cast a non-binding advisory vote to approve the compensation of our Named Executive Officers. This proposal, commonly known as a “say-on-pay” proposal, gives our shareholders the opportunity to express their views on the compensation of our Named Executive Officers.

As described in the “Compensation Discussion and Analysis” section of this Proxy Statement, the primary objectives of our executive compensation program are to attract and retain individuals critical to our long-term success by providing total reward opportunities that, subject to performance:

■ are competitive within our defined markets;

■ fully align pay with our strategic priorities and reinforce a strong performance culture through rewards that reflect Company-wide, department, team, and individual performance;

■ align management, client, and shareholder interests by deferring a significant portion of compensation into Company stock awards;

■ manage risk-taking and conflicts of interest in our incentive plans, maintaining an appropriate balance between base salary, short-term cash incentives, and long-term deferred incentives; and

■ ensure that compensation processes and procedures comply with regulatory requirements, are consistent with market practice, and include effective risk management controls.

We urge our shareholders to review the “Executive Compensation” section of this Proxy Statement, including the compensation tables and related narrative discussion included therein for more information.

The text of the resolution in respect of Proposal 2 (which is proposed as an ordinary resolution) is as follows:

RESOLVED, that the shareholders of the Company hereby approve, on a nonbinding basis, the compensation of our named executive officers as described in the Compensation Discussion and Analysis and in the other tabular and narrative executive compensation disclosures in this Proxy Statement.

Vote Required and Recommendation

As an advisory vote, this proposal is not binding upon us. However, our Human Capital and Compensation Committee values the opinions expressed by shareholders in their vote on this proposal and will consider the outcome of the vote when making future compensation decisions for our Named Executive Officers. This proposal will be approved, on an advisory basis, if the number of votes cast “FOR” exceeds 50% of the total number of votes cast on this matter.

THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE APPROVAL OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.

PROPOSAL 3
RENEWAL OF THE BOARD’S AUTHORITY TO REPURCHASE COMMON STOCK

The Board believes that it is advantageous to renew the authority for the Company to repurchase its own shares in certain circumstances. Under our Articles of Association, the Company may repurchase its own shares subject to and in accordance with the Companies (Jersey) Law 1991 (“Jersey Companies Law”), which generally requires authorization by a special resolution approved by shareholders. Accordingly, the Board proposes to seek this authority in a form consistent with the Jersey Companies Law and US securities laws.

Proposal 3, which will be proposed as a special resolution in accordance with Jersey law, seeks shareholders’ approval of the purchase by the Company of a maximum number of shares which is 16,173,407, representing approximately 10% of the issued share capital of the Company as of February 23, 2024.

The authority sought by this resolution will expire the earlier of (i) the conclusion of the Company’s 2025 Annual Meeting or (ii) November 1, 2025.

The Board will continuously review a possible repurchase of shares, taking into account the Company’s financial position, share price and other investment opportunities. The Board would use this authority only if it believes at the time that such purchase would be in the best interests of shareholders generally.

Any purchases of common stock would be by means of market purchases. The special resolution below sets the maximum and minimum prices for any such purchases. Common stock purchased under this authority may be held as treasury shares. The Jersey Companies Law allows the Company to purchase and hold treasury shares in its issued capital rather than cancelling those shares. Treasury shares do not carry voting rights and have no entitlement to dividends. Treasury shares may be cancelled, sold, or used to meet the Company’s obligations under its employee share plans. Any shares of common stock purchased, but not held as treasury shares, would be cancelled.

As of February 23, 2024, pursuant to the authority approved by shareholders at the 2023 Annual Meeting, the Company repurchased on the open market 5,428,631 shares of common stock since the 2023 Annual Meeting. Purchases include shares repurchased as part of the corporate buyback program and for the purpose of making grants to executives and employees. Such authority will expire at the close of the 2024 Annual Meeting, unless renewed by shareholders.

The text of the resolution in respect of Proposal 3 (which is proposed as a special resolution) is as follows:

RESOLVED, that, pursuant to Article 57 of the Companies (Jersey) Law 1991, the Company be and is hereby generally and unconditionally authorized to make purchases on a stock exchange of its common stock, subject to the following conditions:

■ the maximum number of shares of common stock authorized to be purchased is 16,173,407;

■ the minimum price (exclusive of expenses) that may be paid for a share of common stock is $1.50 par value per share;

■ the maximum price (exclusive of expenses) that may be paid for each share of common stock is an amount that is equal to 105% of the average closing stock price of the preceding five trading days on the New York Stock Exchange;

■ this authority shall expire the earlier of (i) the conclusion of the Company’s 2025 Annual Meeting or (ii) November 1, 2025;

■ a contract to purchase shares under this authority may be made before this authority expires, and concluded in whole or in part after this authority expires; and

■ pursuant to Article 58A of the Companies (Jersey) Law 1991, the Company may hold as treasury shares any shares of common stock of the Company purchased pursuant to the authority conferred in this resolution.

Vote Required and Recommendation

As a special resolution, this proposal will be approved if the number of votes cast “FOR” equals or exceeds two-thirds of the total number of votes cast on this matter. Abstentions and broker non-votes are not considered votes cast and will not impact the outcome of this proposal.

THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE SPECIAL RESOLUTION GRANTING AUTHORITY TO REPURCHASE COMMON STOCK.

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 67

PROPOSAL 4
REAPPOINTMENT AND REMUNERATION OF AUDITORS

The Audit Committee is responsible for the appointment, compensation, retention, and oversight of the Company’s auditors. The Audit Committee evaluates the selection of the Company’s auditors each year and determines whether to reappoint the current auditors or consider other firms. Certain key factors that the Audit Committee considers as part of this evaluation include the quality or service provided, the benefits of tenure versus fresh perspective, business acumen, auditor independence, and the appropriateness of fees relative to both efficiency and audit quality. Based on its annual review, the Audit Committee believes that the continued retention of PricewaterhouseCoopers LLP (“PwC”) as our auditors is in the best interests of the Company and our shareholders. Therefore, the Audit Committee has reappointed PwC, which has served as the Company’s auditors since 2019, to serve as the Company’s auditors.

Pursuant to the Jersey Companies Law, shareholders are required to approve the reappointment of the Company’s auditors each year, and the appointment runs until the conclusion of the next annual general meeting (unless the auditors are removed by resolution of shareholders in a general meeting). Shareholders are also requested to ratify the appointment of PwC as the Company’s independent registered public accounting firm for purposes of US securities laws for the fiscal year ending December 31, 2024, and to authorize the directors to determine the fees to be paid to the auditors.

The text of the resolution in respect of Proposal 4 (which is proposed as an ordinary resolution) is as follows:

RESOLVED, that PricewaterhouseCoopers LLP be appointed as the auditors of the Company from the conclusion of this 2024 Annual Meeting until the conclusion of the Company’s 2025 Annual Meeting, that the appointment of PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm for purposes of United States securities law reporting for the year ending December 31, 2024, be ratified, and that the directors be authorized to determine the fees to be paid to the auditors.

Representatives of PwC are expected to be present at the 2024 Annual Meeting and will have the opportunity to make a statement and to respond to appropriate questions.

Vote Required and Recommendation

As an ordinary resolution, this proposal will be approved if the number of votes cast “FOR” exceeds 50% of the total number of votes cast on this matter. Abstentions and broker non-votes are not considered votes cast and will not impact the outcome of this proposal.

THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR THE REAPPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS OUR AUDITORS, TO RATIFY THEIR APPOINTMENT AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM, AND TO AUTHORIZE THE DIRECTORS TO DETERMINE THE FEES TO BE PAID TO THE AUDITORS.

Pre-Approval Policy

All services performed by PwC were approved in accordance with the approval policy and procedures adopted by the Audit Committee. This policy describes the permitted audit, audit-related, tax and other services that our independent auditor may perform. Under the policy, any service to be provided to the Company by its independent auditor must be pre-approved by the Audit Committee. Generally, pre-approval is provided at regularly scheduled committee meetings, however, the authority to grant specific pre-approval between meetings, as necessary, has been delegated to the Audit Committee Chair. The Audit Committee Chair must update the Audit Committee at the next regularly scheduled committee meeting of any services that were granted specific approval.

The Audit Committee generally approves a narrow range of fees associated with each proposed service to incorporate appropriate oversight and control of the independent auditor relationship.

At each meeting, the Audit Committee reviews the status of services and fees incurred year-to-date against the original approved services and the forecast of remaining services and fees for the fiscal year.

AUDIT COMMITTEE REPORT

The Audit Committee assists the Board in its oversight of the Company’s financial reporting process. The Audit Committee’s responsibilities include, among others: (i) overseeing the integrity of the Company’s financial statements; (ii) evaluating the qualifications, independence, and performance of the Company’s independent auditors; (iii) reviewing the organizational structure and qualifications of the members of the Company’s internal Audit department; and (iv) obtaining reports from management and the independent auditors concerning the Company’s compliance with applicable legal and regulatory standards. Management has the primary responsibility for the Company’s financial statements and the reporting process, including the system of internal controls.

The Audit Committee has received the written disclosures and the letter from its independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm the independent registered public accounting firm’s independence.

Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board, and the Board approved, inclusion of the Company’s audited financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, for filing with the SEC.

We will reimburse brokers and other nominees that are requested to forward soliciting materials to the beneficial owners of the shares they hold of record.

Why did I receive a Notice of Internet Availability of Proxy Materials instead of the proxy materials?

We distribute our proxy materials to most shareholders over the Internet using “Notice and Access” delivery, as permitted by SEC rules. We elected to use this method for most shareholders because it reduces our print and mail costs and the environmental impact of the Meeting. See “Householding” below for additional information.

Where can I find the voting results of the 2024 Annual Meeting?

The preliminary voting results will be announced at the 2024 Annual Meeting. The final voting results will be disclosed by the Company in a Current Report on Form 8-K to be filed with the SEC within four business days following the Meeting and made available on the Company’s website at www.janushenderson.com/AGM2024.

OTHER INFORMATION

This Proxy Statement includes website addresses and references to additional materials found on those websites. The information on our Corporate Governance webpage, the Responsibility Report, and any other information on our website that we may refer to herein is not incorporated by reference into, and does not form any part of, this Proxy Statement. Any targets or goals discussed in our Responsibility Report and in this Proxy Statement may be aspirational, and as such, no guarantees or promises are made that these goals will be met. Furthermore, statistics and metrics disclosed in this Proxy Statement and in the Responsibility Report are estimates and may be based on assumptions that turn out to be incorrect.

Forward-Looking Statements

Certain statements in this Proxy Statement not based on historical facts are “forward-looking statements” within the meaning of the federal securities laws, including the Private Securities Litigation Reform Act of 1995, as amended, Section 21E of the Securities Exchange Act of 1934, as amended, and Section 27A of the Securities Act of 1933, as amended. 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. 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 Proxy Statement include, but are not limited to, risks, uncertainties, assumptions, and factors discussed in our Annual Report on Form 10-K for the year ended December 31, 2023, and in other filings or furnishings made by the Company with the SEC from time to time.

Shareholder Proposals for 2025 Annual Meeting

Shareholders who wish to present a proposal in accordance with SEC Rule 14a-8 under the Exchange Act for inclusion in our proxy materials to be distributed in connection with our 2024 Annual Meeting must submit their proposals in accordance with that rule so they are received by the Company Secretary at the address set forth below no later than the close of business on November 22, 2024. If the date of our 2025 Annual Meeting is more than 30 days before or after May 1, 2025, then the deadline to timely receive such material will be a reasonable time before we begin to print and send our proxy materials. Failure to deliver a proposal in accordance with this procedure may result in it not being deemed timely received. As the rules of the SEC make clear, simply submitting a timely proposal does not guarantee that it will be included in our proxy materials.

Our Articles of Association require that shareholders who intend to propose, outside of Rule 14a-8 under the Exchange Act, any resolution, including nominating candidates for election as directors, at our 2025 Annual Meeting must provide notice of such proposals in writing to our Company Secretary between the close of business on January 14, 2025, and the close of business on January 31, 2025. However, if the date of our 2025 Annual Meeting is more than 30 days before or more than 60 days after May 1, 2025, the shareholder’s notice must be delivered in writing (i) no earlier than the close of business on the 120th day prior to the 2025 Annual Meeting and (ii) no later than the close of business on the later of (a) the 90th day prior to such 2025 Annual Meeting or (b) the 10th day after public announcement of the date of such 2025 Annual Meeting is first made by the Company. The notice must set forth the information required by our Articles of Association.

Such proposals should be sent to our Company Secretary in writing to Janus Henderson Group plc, Attn: Company Secretary, 151 Detroit Street, Denver, Colorado 80206, USA. To be included in the Company’s proxy materials, the proposal must comply with the requirements as to form and substance established by the SEC and our Articles of Association and must be a proper subject for shareholder action under Jersey law.

In addition to satisfying the foregoing requirements, to comply with the SEC’s universal proxy rules, shareholders who intend to solicit proxies in support of director nominees other than our nominees must provide timely notice that sets forth the information required by Rule 14a-19 under the Exchange Act. To the extent any information is required by Rule 14a-19(b) that is not required under our Bylaws, it must be received by March 2, 2025.

JANUS HENDERSON GROUP PLC  ■  2024 Proxy Statement 75

Householding

SEC rules permit companies and intermediaries (such as banks and brokers) to send a single copy of the proxy materials or Notice of Internet Availability of Proxy Materials, as applicable, to two or more shareholders who share the same address, subject to certain conditions. This “householding” rule benefits both the shareholders and the Company by reducing the volume of duplicate information shareholders receive, reducing the Company’s printing and mailing costs, and reducing the environmental impact of our meeting. Accordingly, a single copy of the Notice of Internet Availability of Proxy Materials (or proxy materials) will be delivered to multiple shareholders sharing an address, unless contrary instructions have been received from the affected shareholders.

If one set of these documents was sent to your household for the use of all the Company’s shareholders in your household and one or more of you would prefer to receive additional sets, or if multiple copies of these documents were sent to your household and you want to receive one set, please contact our transfer agent, Computershare, P.O. Box 43078, Providence, RI 02940-3078, USA; toll-free 866-638-5573; or www.computershare.com/investor.

IF A BROKER, BANK, OR OTHER NOMINEE HOLDS YOUR SHARES, PLEASE CONTACT YOUR BROKER, BANK, OR OTHER NOMINEE DIRECTLY IF YOU HAVE QUESTIONS ABOUT DELIVERY OF MATERIALS, REQUIRE ADDITIONAL COPIES OF THE PROXY MATERIALS, OR WISH TO RECEIVE MULTIPLE COPIES OF THE PROXY MATERIALS, WHICH WOULD REQUIRE YOU TO STATE THAT YOU DO NOT CONSENT TO HOUSEHOLDING.

Presentation of Accounts

Under Jersey law, the directors are required to present the accounts of the Company and the reports of the auditors before shareholders at a general meeting. Therefore, the accounts of the Company for the fiscal year ended December 31, 2023, will be presented to the shareholders at the 2024 Annual Meeting.

ANNEX A
RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

The Company presents its financial results in US dollars and in accordance with accounting principles generally accepted in the United States of America (“GAAP”). However, management evaluates our profitability and our ongoing operations using additional non-GAAP financial measures that exclude costs or benefits that are not part of our ongoing operations. Management uses these performance measures to evaluate the business, and adjusted values are consistent with internal management reporting. We have provided a reconciliation below of our non-GAAP financial measures to the most directly comparable GAAP measures.

(1)	We contract with third-party intermediaries to distribute and service certain of our 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 us and passed through to third-party intermediaries who are responsible for performing the applicable services. The majority of distribution and servicing fees we collect 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, we perform the distribution and servicing activities and retain the applicable fees. Revenues for distribution and servicing activities performed by us are not deducted from GAAP revenue.
(2)	Adjustments for all periods presented include rent expense and other rent-related adjustments for subleased office space, and the acceleration of long-term incentive plan expense related to the departure of certain employees. The adjustments for the year ended December 31, 2023, also include a $9.3 million charge related to a separately-managed account trade error. 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. For segregated mandate contracts, the intangible asset is amortized on a straight-line basis over the expected life of the contracts. Adjustments also include impairment charges of our goodwill, certain mutual fund investment management contracts, client relationships and trademarks. JHG management believes these non-cash and acquisition related costs do not represent our ongoing operations.
(4)	Operating margin is operating income divided by revenue.
(5)	Adjusted operating margin is adjusted operating income divided by adjusted revenue.
(6)	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 adjustments related to liquidated JHG entities. Adjustments for the year ended December 31, 2022, primarily relate to accumulated foreign currency translation adjustments related to liquidated JHG entities, rental income from subleased office space and a one-time charge related to the sale of Intech. Adjustments for the year ended December 31, 2021, primarily relate to rental income from subleased office space and a one-time contingent consideration adjustment in relation to the sale of Geneva. JHG management believes these expenses do not represent our ongoing operations.
(7)	The tax impact of the adjustments is calculated based on the US or foreign statutory tax rate as they relate to each adjustment. Certain adjustments are either not taxable or not tax deductible. Adjustments for the year ended December 31, 2023, were also impacted by the change to our state tax rate. As a result, the US deferred tax assets and liabilities were revalued from 23.9% to 23.5%, creating a non-cash deferred tax benefit of $8.8 million. In addition, the 2021 adjustment includes non-cash deferred tax expense resulting from the revaluation of certain UK deferred tax assets and liabilities due to the enactment of the Finance Act 2021, which increased the UK corporation tax rate from 19% to 25% beginning in April 2023.
(8)	Diluted earnings per share is net income attributable to JHG common shareholders divided by weighted average diluted common shares outstanding.
(9)	Adjusted diluted earnings per share is adjusted net income attributable to JHG common shareholders divided by weighted average diluted common shares outstanding.

Pay vs Performance [Table Text Block]

Pay Versus Performance Table for Fiscal Year 2023

The Pay Versus Performance Table below discloses the relationship between the compensation actually paid (“CAP”) to the executive officers and the Company’s financial performance during the years ended December 31, 2020, 2021, 2022, and 2023. The compensation information presented in this table is different from compensation information presented in the CD&A and in the Summary Compensation Table above. The differences can largely be attributed to variation in the treatment of stock awards in each of these tables as described in greater detail below.

■ The compensation presented in the “2023 Compensation for the CEO and Other NEOs” section of the CD&A illustrates compensation paid or granted to NEOs based on their performance during the 2023 performance period as determined by the scorecard approach. The stock awards shown as “JHG RSUs” and “JHG PSUs” in these tables include the portions of 2023 total variable compensation that will be deferred into JHG RSUs and JHG PSUs when they are granted in February 2024.

■ In accordance with SEC rules, the Stock Awards column in the Summary Compensation Table includes the aggregate grant date fair values of the RSUs and PSUs granted during 2023, even though the number of RSUs and PSUs granted was determined based on the 2022 performance of the executive officers.

■ The Pay Versus Performance Table below differs from both the information presented in the CD&A and in the Summary Compensation Table, because it calculates actual compensation based on different methodologies, including the value of outstanding unvested stock awards as of December 31, 2023.

(1) The amounts in the following table represent each of the amounts deducted and added to the equity award values for our Principal Executive Officer (“PEO”), which in our case is the CEO, for the applicable year for purposes of computing the CAP amounts appearing in these columns of the Pay Versus Performance Table:

(2) The amounts in the following table represent each of the amounts deducted and added to the equity award values for the non-PEO NEOs for the applicable year for purposes of computing the CAP amounts appearing in the Pay Versus Performance Table:

(ii)	Represents the total adjustments to the Average Summary Compensation Table Total in respect of equity awards for the applicable year, as reflected in CAP.

(iii)

2023 NEOs include: Messrs. Thompson and Lowry and Mses. Fogo and Rosenberg.

(iv)

2022 NEOs include: Mr. Thompson, Mses. Cain, Fogo, Rosenberg, and Tiphani Krueger, former Global Head of Human Resources. Mr. Thompson served as our Interim Chief Executive Officer from April 1, 2022, until Mr. Dibadj’s appointment on June 21, 2022. In connection with Mr. Thompson’s interim role, he continued to receive the same salary he received in 2022 for his role as Chief Financial Officer. Accordingly, Mr. Thompson’s 2022 compensation has been included in the average compensation column for our non-PEO NEOs.

(v) In 2021, the Compensation Committee considered the uncertainty caused by the former CEO’s retirement, combined with an increase in shareholder activism, and decided to grant one-time Transition Awards to each of the NEOs to reinforce leadership stability. Such awards were granted in February 2022 after the end of the 2021 performance year. An unintended consequence of this timing is that the Transition Awards are included in 2022 compensation, which could be interpreted to suggest that our NEOs received compensation increases for disappointing performance in 2022 rather than the performance year in which the value was determined.

(vi)	2021 NEOs include: Mr. Thompson, Mses. Cain, Fogo, and Rosenberg.
(vii)	2020 NEOs include: Mr. Thompson, Mses. Cain, Fogo, and Rosenberg.

(3)	The companies included in the peer group TSR calculations are the publicly traded companies included in the S&P US BMI Asset Management & Custody Banks Index used by the Company for purposes of disclosing our cumulative TSR in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023. The S&P US BMI Asset Management & Custody Banks Index is a market-value weighted index of 40 asset management companies.
(4)	In addition to financial results reported in accordance with GAAP, we report certain financial measures on a non-GAAP basis. These measures are not in accordance with, or a substitute for, GAAP, and our financial measures may differ from the non-GAAP financial measures used by other companies. For additional information, see Annex A, “Reconciliation of Non-GAAP Financial Measures”.
(5)	Adjusted operating margin is adjusted operating income divided by adjusted revenue for 2023. This measure has been designated as the “Company-Selected Measure” for 2023, in accordance with SEC rules, and represents the most important financial performance measure (that is not otherwise required to be disclosed in the table) used by the Company to link CAP to our NEOs in 2023.

2023 NEOs include: Messrs. Thompson and Lowry and Mses. Fogo and Rosenberg.

(iv)

2022 NEOs include: Mr. Thompson, Mses. Cain, Fogo, Rosenberg, and Tiphani Krueger, former Global Head of Human Resources. Mr. Thompson served as our Interim Chief Executive Officer from April 1, 2022, until Mr. Dibadj’s appointment on June 21, 2022. In connection with Mr. Thompson’s interim role, he continued to receive the same salary he received in 2022 for his role as Chief Financial Officer. Accordingly, Mr. Thompson’s 2022 compensation has been included in the average compensation column for our non-PEO NEOs.

(v) In 2021, the Compensation Committee considered the uncertainty caused by the former CEO’s retirement, combined with an increase in shareholder activism, and decided to grant one-time Transition Awards to each of the NEOs to reinforce leadership stability. Such awards were granted in February 2022 after the end of the 2021 performance year. An unintended consequence of this timing is that the Transition Awards are included in 2022 compensation, which could be interpreted to suggest that our NEOs received compensation increases for disappointing performance in 2022 rather than the performance year in which the value was determined.

(vi)	2021 NEOs include: Mr. Thompson, Mses. Cain, Fogo, and Rosenberg.
(vii)	2020 NEOs include: Mr. Thompson, Mses. Cain, Fogo, and Rosenberg.

[1] The amounts in the following table represent each of the amounts deducted and added to the equity award values for the non-PEO NEOs for the applicable year for purposes of computing the CAP amounts appearing in the Pay Versus Performance Table:

[2] The companies included in the peer group TSR calculations are the publicly traded companies included in the S&P US BMI Asset Management & Custody Banks Index used by the Company for purposes of disclosing our cumulative TSR in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023. The S&P US BMI Asset Management & Custody Banks Index is a market-value weighted index of 40 asset management companies.

[3] Adjusted operating margin is adjusted operating income divided by adjusted revenue for 2023. This measure has been designated as the “Company-Selected Measure” for 2023, in accordance with SEC rules, and represents the most important financial performance measure (that is not otherwise required to be disclosed in the table) used by the Company to link CAP to our NEOs in 2023.

[4] In addition to financial results reported in accordance with GAAP, we report certain financial measures on a non-GAAP basis. These measures are not in accordance with, or a substitute for, GAAP, and our financial measures may differ from the non-GAAP financial measures used by other companies. For additional information, see Annex A, “Reconciliation of Non-GAAP Financial Measures”.

[5] 2023 NEOs include: Messrs. Thompson and Lowry and Mses. Fogo and Rosenberg.

In connection with Mr. Thompson’s interim role, he continued to receive the same salary he received in 2022 for his role as Chief Financial Officer. Accordingly, Mr. Thompson’s 2022 compensation has been included in the average compensation column for our non-PEO NEOs.
