References throughout this report to “AMG,” “we,” “us,” “our,” the “Company” and similar references refer to Affiliated Managers Group, Inc., unless otherwise stated or the context otherwise requires. Item 1. Business AMG is a strategic partner to leading independent investment firms globally. Our strategy is to generate long-term value by investing in a diverse array of high-quality independent partner-owned firms, referred to as “Affiliates,” through a proven partnership approach, and allocating resources across our unique opportunity set to the areas of highest growth and return. With their entrepreneurial, investment-centric cultures and alignment of interests with clients through direct equity ownership by firm principals, independent firms have fundamental competitive advantages in offering unique return streams to the marketplace. Through AMG’s distinctive approach, we enhance these advantages to magnify the long-term success of our Affiliates and actively support their independence. Our innovative model enables each Affiliate’s management team to retain autonomy and significant equity ownership in their firm, while they leverage our strategic capabilities and insight, including growth capital, product strategy and development, capital formation, and incentive alignment and succession planning. As of December 31, 2023, our aggregate assets under management were approximately $673 billion across a diverse range of private markets, liquid alternative, and differentiated long-only investment strategies. We generate long-term value by investing in new and existing Affiliates, and strategic value-add capabilities through which we can leverage our scale and resources on behalf of our Affiliates, and then by returning excess capital to shareholders, primarily through share repurchases. We are focused on investing in areas of secular growth and long-term client demand, including in private markets, liquid alternatives, Asia, wealth management, and sustainable investing; accordingly, we partner with leading independent investment firms managing differentiated strategies in the aforementioned growth areas. Through our partnership approach, we hold meaningful equity interests in each of our Affiliates, and typically each Affiliate’s management team retains a significant equity interest in their own firm. Affiliate management equity ownership (along with our long-term ownership) aligns our interests and preserves Affiliate management equity incentives, including the opportunity for Affiliate management to participate directly in the long-term future growth and profitability of their firms. Our goal in partnering with Affiliates is to be an excellent and engaged partner, and to collaborate with Affiliates to magnify each firm’s long-term success. We take a long-term partnership approach with our Affiliates, which provides stability in facilitating succession planning across generations of Affiliate management principals. We are uniquely able to provide strategic capabilities and expertise across various stages of our Affiliates’ growth. In certain cases, we invest in our Affiliates by providing growth capital or complementing their own marketing resources with our proven product development and distribution capabilities. We also provide succession planning solutions and advice to many of our Affiliates, which can include a degree of liquidity and financial diversification along with incentive alignment for next-generation partners. 1 Table of Contents Our innovative partnership approach enhances our Affiliates’ ability to achieve their long-term strategic objectives while maintaining their independence and autonomy, and therefore, their unique entrepreneurial and investment-centric cultures. We believe that clients recognize these fundamental characteristics of partner-owned firms, as well as the alignment created by direct equity ownership by firm principals, as competitive advantages in achieving client investment goals and objectives. Our investment approach preserves these essential elements of our Affiliates’ success. Independent firms seeking an institutional partner are attracted to our unique partnership approach and our global reputation as a successful strategic partner to independent investment firms around the world. We anticipate that the principal owners of independent investment firms will continue to seek access to an evolving range of growth and succession solutions. We will, therefore, continue to have a significant opportunity to invest in additional high-quality firms across the global investment management industry. In addition, we have the opportunity to make additional equity investments in our existing Affiliates, or invest in their growth by providing seed or other growth capital. We are well-positioned to execute upon these investment opportunities through our: • • • • • established process of identifying and cultivating high-quality prospective Affiliates; broad industry network and proprietary relationships developed with prospects over many years; substantial experience and expertise in structuring and negotiating transactions; global reputation as an excellent partner to our Affiliates, having provided innovative solutions for the strategic needs of independent investment firms across three decades; and successful engagement with our Affiliates to enhance their long-term prospects, including through product development, distribution, and other business development initiatives. Investment Management Operations Our Affiliates provide a diverse range of differentiated return streams through their specialized investment processes. Given their long-term performance records, our Affiliates are recognized as being among the industry’s leaders in their respective investment disciplines. Our Affiliates’ attractive return streams are utilized in client portfolios to address a range of specialized needs for institutional and wealth clients globally; certain Affiliates also provide investment management and customized investment counseling and fiduciary services to high net worth individuals and families and institutional clients. With meaningful earnings contributions from each of private markets, liquid alternatives, and differentiated long-only strategies (which includes global equities, U.S. equities, and multi-asset and fixed income strategies), AMG’s business profile is highly diversified. As of December 31, 2023, our Affiliates managed approximately $673 billion across a broad range of investment styles and geographies, in alternative, equity, and multi-asset and fixed income strategies, as the following chart illustrates. 2 Table of Contents Assets Under Management Our Affiliates currently manage assets for investors in more than 50 countries, including all major developed markets. Our Affiliates distribute their investment services and products to institutional and wealth clients through direct sales efforts and established relationships with consultants and intermediaries around the world through their own business development capabilities. In addition, AMG supports the long-term growth and client diversification of our Affiliates by operating a distribution platform in which each Affiliate may choose to participate. Our distribution capabilities, which provide access to institutional and wealth clients, serve to extend the reach of our Affiliates’ own business development efforts, including strategy, marketing, distribution, and product development, and our Affiliates benefit from the expertise of our senior sales and marketing professionals servicing the U.S., Europe, the UK, the Middle East, Asia, and Australia. Our Partnership Structure and Relationship with Affiliates We believe that Affiliate management equity ownership in their firms (along with our long-term partnership) aligns our and our Affiliates’ interests, enhances Affiliate management equity incentives, and preserves the opportunity for Affiliate management to participate directly in the long-term future growth and profitability of their firm. Although the equity structure of each Affiliate investment is tailored to meet the needs of the management equity owners of the particular Affiliate, we typically maintain a meaningful equity interest in the Affiliate, with a significant equity interest retained by Affiliate management principals. Each of our Affiliates operates through distinct legal entities, which affords us the flexibility to design a separate operating agreement for each Affiliate that reflects customized arrangements with respect to governance, economic participation, equity incentives, and the other terms of our relationship. In each case, the operating agreement provides for a governance structure that gives Affiliate management the authority to manage and operate the business on a day-to-day basis. The operating agreement also reflects the specific terms of our economic participation in the Affiliate, which, in each case, uses a “structured partnership interest” to ensure alignment of our economic interests with those of Affiliate management. The form of our structured partnership interests in our Affiliates differs from Affiliate to Affiliate and ranges from structures where we contractually share in the Affiliate’s revenue without regard to expenses, comprising Affiliates that contribute a majority of our Consolidated revenue, to others where we contractually share in the Affiliate’s revenue less agreed-upon expenses. Further, the structure at a particular Affiliate, or the expenses that we agree to share in, may change during the course of our investment. Where we share in the Affiliate’s revenue without regard to expenses, the Affiliate allocates a specified percentage of its revenue to us and Affiliate management, while using the remainder for operating expenses and additional distributions to Affiliate management. We and Affiliate management, therefore, participate in any increase or decrease in revenue, and only Affiliate management participates in any increase or decrease in expenses. Under these structured partnership interests our contractual share of revenue generally has priority over distributions to Affiliate management. 3 Table of Contents Where we share in the Affiliate’s revenue less agreed-upon expenses, we benefit from any increase in revenue or any decrease in the agreed-upon expenses, but also have exposure to any decrease in revenue or any increase in such agreed-upon expenses. The degree of our exposure to agreed-upon expenses from these structured partnership interests varies by Affiliate, and includes several Affiliates in which we fully share in the expenses of the business. When we own a controlling equity interest in an Affiliate, we consolidate the Affiliate’s financial results into our Consolidated Financial Statements. When we do not own a controlling equity interest in an Affiliate, but have significant influence, we account for our interest in the Affiliate under the equity method. Under the equity method of accounting, we do not consolidate the Affiliate’s results into our Consolidated Financial Statements. Instead, our share of earnings or losses, net of amortization and impairments, is included in Equity method income (net) in our Consolidated Statements of Income, and our interest in these Affiliates is recorded in Equity method investments in Affiliates (net) in our Consolidated Balance Sheets. Whether we consolidate an Affiliate’s financial results or use the equity method of accounting, we maintain the same innovative partnership approach and offer support and assistance in substantially the same manner for all of our Affiliates. From time to time, we may restructure our interest in an Affiliate to better support the Affiliate’s growth strategy, but only if doing so is in the best interest of the Affiliate’s business, management partners, and clients, as well as our stakeholders. Competition Our Affiliates compete with numerous investment management firms globally, as well as with subsidiaries of larger financial organizations. These firms may have significantly greater financial, technological, and marketing resources; access to captive distribution; and assets under management. Many of these firms may offer products and services that our Affiliates may not, in particular investment strategies such as passively-managed products, including exchange traded funds, which typically carry lower fee rates. Certain Affiliates offer their investment management services to the same client types and, from time to time, may compete with each other for clients. In addition, there are relatively few barriers to entry for new investment management firms, especially for those providing investment management services to institutional and high net worth investors. We believe that the most important factors affecting our Affiliates’ ability to compete for clients are the: • • • investment performance, investment styles, and reputations of our Affiliates and their management teams; differentiation of our Affiliates’ investment strategies and products and the continued development of investment strategies and products to meet the evolving needs and demands of investors; depth and continuity of our and our Affiliates’ client relationships and the level of client service offered; • maintenance of strong business relationships by us and our Affiliates with major intermediaries; and • continued success of our and our Affiliates’ distribution efforts. Additionally, our strategy includes investing in independent partner-owned investment firms, and in this area we compete with a number of acquirers and investors, including investment management companies, private equity firms, sovereign wealth funds, and larger financial organizations. We believe that the most important factors on which we compete for future investments are purchase price and liquidity; our partnership investment model, including the equity incentive structures and access to strategic capabilities we offer; and the breadth and depth of our relationships, and our reputation, with investment firm prospects. Government Regulation Our Affiliates offer their investment management services and products around the world, and are subject to complex and extensive regulation by regulatory and self-regulatory authorities and exchanges in various jurisdictions. Virtually all aspects of the asset management business, including the provision of advice, investment strategies and trading, fund sponsorship, and product-related sales and distribution activities, are subject to regulation. These regulations are primarily intended to protect the clients of investment advisers and generally grant regulatory authorities broad administrative and enforcement powers. The majority of our Affiliates are registered with the SEC as investment advisers under the Investment Advisers Act of 1940, as amended (the “Advisers Act”). The Advisers Act imposes numerous obligations on registered investment advisers, including fiduciary duties, compliance and disclosure obligations, and operational and recordkeeping requirements. Our Affiliates operating outside of the U.S. may be subject to the Advisers Act and are also subject to regulation by various regulatory and self-regulatory authorities and exchanges in the relevant jurisdictions, including, for those Affiliates active in the UK, the Financial Conduct Authority (the “FCA”). Many of our Affiliates also sponsor or advise registered and unregistered 4 Table of Contents funds in the U.S. and in other jurisdictions, and are subject to regulatory requirements in the jurisdictions where those funds are sponsored or offered, including, with respect to mutual funds in the U.S., the Investment Company Act of 1940, as amended (the “Investment Company Act”). The Investment Company Act governs the operations of mutual funds and imposes obligations on their advisers, including investment restrictions and other governance, compliance, reporting, and fiduciary obligations relating to the management of mutual funds. Many of our Affiliates are also subject to directives and regulations in the European Union and other jurisdictions relating to funds, such as the Undertakings for the Collective Investment of Transferable Securities (“UCITS”) Directive and the Alternative Investment Fund Managers Directive (“AIFMD”), with respect to depositary functions, remuneration policies and sanctions, among other matters. Our Affiliates’ sales and marketing activities are subject to regulation by authorities in the jurisdictions in which they offer investment management products and services. Our Affiliates’ ability to transact business in these jurisdictions, and to conduct related cross-border activities, is subject to the continuing availability of regulatory authorizations and exemptions. Through our distribution platform, we also engage in sales and marketing activities that extend the reach of our Affiliates’ own business development efforts, and which are subject to regulation in numerous jurisdictions. Our U.S. wealth distribution subsidiary is registered with the SEC under the Advisers Act. This subsidiary sponsors mutual funds registered under the Investment Company Act, and serves as an investment adviser and/or administrator for our fund complex. In the UK, our institutional distribution subsidiary is regulated by the FCA. We also have institutional distribution subsidiaries or branches of subsidiaries regulated by the Dubai Financial Services Authority and the Australian Securities and Investments Commission, and our activities in the European Union are regulated by various regulators in European jurisdictions. Certain of our Affiliates and our U.S. wealth distribution subsidiary are subject to the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), and related regulations, with respect to retirement plan clients. ERISA imposes duties on persons who are fiduciaries under ERISA, and prohibits certain transactions involving related parties to a retirement plan. The U.S. Department of Labor administers ERISA and regulates investment advisers who service retirement plan clients, and has been increasingly active in proposing and adopting additional regulations applicable to the investment management industry. Certain of our Affiliates and our U.S. wealth distribution subsidiary are also members of the National Futures Association and are regulated by the U.S. Commodity Futures Trading Commission (“CFTC”) with respect to the management of funds and other products that utilize futures, swaps or other CFTC-regulated instruments. In addition, certain of our Affiliates and our U.S. wealth broker-dealer subsidiary are registered broker-dealers and members of the Financial Industry Regulatory Authority (“FINRA”), for the purpose of distributing funds or other products. FINRA has adopted extensive regulatory requirements relating to sales practices, registration of personnel, compliance and supervision, and compensation and disclosure. FINRA and the SEC have the authority to conduct periodic examinations of member broker-dealers, and may also conduct administrative proceedings. These broker-dealers are also subject to net capital rules in the U.S. that mandate the maintenance of certain levels of capital, and our Affiliates and our other distribution subsidiaries may also be subject to other regulatory capital requirements imposed by non-U.S. regulatory authorities. Due to the extensive laws and regulations to which we and our Affiliates are subject, we and our Affiliates must devote substantial time, expense and effort to remain current on, and to address, legal and regulatory compliance matters. We have established compliance programs for each of our operating subsidiaries, and each of our Affiliates has established compliance programs to address regulatory compliance requirements for its operations. We and our Affiliates have experienced legal and compliance professionals in place to address these requirements, and have relationships with various legal and regulatory advisers in each of the countries where we and our Affiliates conduct business. See “Item 1A. Risk Factors”. Human Capital Management As of December 31, 2023, we and our Affiliates had approximately 4,000 employees, the substantial majority of which were employed by our Affiliates and not by AMG. Each Affiliate’s management team retains autonomy in managing and operating their business on a day-to-day basis, including with respect to their human capital. Given this, the following is a discussion of AMG’s workforce, or approximately 250 of the total employees, and the policies and cultural initiatives which pertain to our human capital. Our employees and our reputation are our most important assets, and attracting, retaining, and motivating top talent to execute on our strategic business objectives is a fundamental imperative. We support that imperative through our strong values-based culture, commitment to career development and training, employee engagement initiatives, attractive compensation and benefits programs, attention to succession planning, and fostering of organizational diversity at all levels of our organization. 5 Table of Contents Our leadership training and sponsored skills development programs cover a wide range of subject area expertise as well as career development generally, and are anchored on a comprehensive performance review process, which includes a company-wide 360-degree review program. Further, we support employees’ educational pursuits relating to degree programs and certifications through company-supported time off for professional development and flexible work arrangements tailored to individual employees’ educational goals. We regularly conduct company-wide surveys to solicit feedback from our employees on a variety of topics, including corporate culture, philanthropic interests, and general job satisfaction, which help us to enhance employee engagement and retention. Our annual anonymous employee engagement survey reported an employee satisfaction rating of 90% in 2023, which we attribute to our focus and commitment to our employees, our entrepreneurial culture and partnership orientation, and our meaningful involvement with communities surrounding our offices. We prioritize employee engagement through a range of cross-functional, multi-level communication and collaboration mediums through both in- person and virtual forums, including small working group lunches, company-wide gatherings and town halls, management off-sites, and charitable volunteer activities. Through employee participation in our corporate philanthropic initiatives across our global offices, we are committed to giving back to the communities in which we work and live, and we believe that these initiatives also support our efforts to attract and retain employees. We provide company-supported time off to encourage employees in their charitable endeavors. We also offer a formal gift-matching program to match employee donations to eligible non-profit institutions through AMG and The AMG Charitable Foundation, as well as a volunteer-matching program, wherein volunteer hours are matched with philanthropic credits that employees may donate to eligible organizations. Through our matching program as well as through direct grants, AMG and The AMG Charitable Foundation have made donations to more than 800 organizations around the world to date. We believe that organizational diversity results in a highly creative and innovative workforce, and are committed to fostering and promoting an inclusive and diverse work environment. We seek to recruit the best people for the job without regard to gender, ethnicity or other protected traits, and it is our policy to comply fully with all domestic, foreign and local laws relating to discrimination in the workplace. We have achieved gender diversity of 38% across management positions in our workforce, and nearly half (47%) of our employees are women. Further, three of eight (38%) independent members of our Board of Directors are women, and two of eight (25%) independent directors are ethnically diverse, in each case, above the average of S&P 500 companies. In addition, two of our three Board committees are chaired by women. We continually seek to enhance the diversity of our employee base, as our employees around the world contribute their distinct perspectives to improve our business and the communities in which our businesses operate. Our executive management team has responsibility for diversity initiatives, in coordination with our Sustainability Committee, and reviews these initiatives with our Board of Directors at least annually. Our Website Our website is www.amg.com. Our website provides information about us, and, from time to time, we may use it to distribute material company information. We routinely post financial, investment performance, and other important information regarding the Company in the Investor Relations section of our website and we encourage investors to consult that section regularly. The Investor Relations section of our website also includes copies of our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K, including exhibits, and any amendments to those reports filed or furnished with the SEC pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended. We make these reports available through our website as soon as reasonably practicable after our electronic filing of such materials with, or the furnishing of them to, the SEC. The information contained or incorporated on our website is not a part of this Annual Report on Form 10-K. 6 Table of Contents Item 1A. Risk Factors We and our Affiliates face a variety of risks that are substantial and inherent in our businesses. The following are some of the more important factors that could affect our and our Affiliates’ businesses. Investors should carefully consider these risks, along with the other information contained in this Annual Report on Form 10-K, before making an investment decision regarding our common stock or other publicly-listed securities. There may be additional risks of which we are currently unaware, or which we currently consider immaterial. Any of these risks could have a material adverse effect on our financial condition, results of operations, and the market price of our common stock. Certain statements in “Risk Factors” are forward-looking statements. See “Forward-Looking Statements.” RISKS RELATED TO OUR INDUSTRY, BUSINESS AND OPERATIONS Our financial results depend on our Affiliates’ receipt of asset- and performance-based fees, and are impacted by investment performance, as well as changes in fee levels, product mix, and the relative levels of assets under management among our Affiliates. Our financial results depend on our Affiliates’ receipt of asset- and performance-based fees, which may vary substantially from year to year. Our Affiliates’ ability to maintain current fee levels depends on a number of factors, including our Affiliates’ investment performance, as well as competition and trends in the investment management industry, such as investor demand for passively-managed products, including index and exchange traded funds, that typically carry lower fee rates, or preferences for other developing strategies or trends. Further, different types of assets under management can generate different ratios of asset-based fees to assets under management (“asset-based fee ratio”), based on factors such as the investment strategy and the type of client. Thus, a change in the composition of our assets under management, either within an Affiliate or among our Affiliates, could result in a decrease in our aggregate fees even if our aggregate assets under management remains unchanged or increases. Products that use fee structures based on investment performance may also vary significantly from period to period, depending on the investment performance of the particular product. For some of our Affiliates, performance-based fees include a high-watermark provision, which generally provides that if a product underperforms on an absolute basis or relative to its benchmark, it must regain such underperformance before the Affiliate will earn any performance-based fees. In addition, in the ordinary course of business, our Affiliates may reduce or waive fees on certain products for particular time periods, to attract or retain assets or for other reasons. No assurances can be given that our Affiliates will be able to maintain current fee structures or levels. A reduction in the fees that our Affiliates receive could have an adverse impact on our financial condition and results of operations. Additionally, our structured partnership interests are tailored to meet the needs of each Affiliate and are therefore varied, and our earnings may be adversely affected by changes in the relative performance or in the relative levels and mix of assets under management among our Affiliates, independent of our aggregate operating performance measures. Challenging market conditions, volatility or slowdowns affecting a particular asset class, client type, product structure, geographic region, industry or other category of investment could have a significant adverse impact on a specific Affiliate if its investments are concentrated in that area, which could result in lower investment returns and in turn, lower fees earned at that Affiliate. Further, certain Affiliates contribute more significantly to our results than other Affiliates and, therefore, changes in fee levels, product mix, assets under management, or investment performance of such Affiliates could have a disproportionate adverse impact on our financial condition and results of operations. Our financial results could be adversely affected by any reduction in our assets under management, which could reduce the asset- and performance- based fees earned by our Affiliates. Our financial results may be impacted by changes in the total level of our assets under management. The total level of our assets under management generally or with respect to particular products or Affiliates could be adversely affected by conditions outside of our control, including: • • a decline in the market value of our assets under management, due to declines or heightened volatility in the capital markets, fluctuations in foreign currency exchange rates and interest rates, the recent inflationary environment, changes in the yield curve, and other market factors; changes in investor risk tolerance or investment preferences, which could result in investor allocations away from strategies and products offered by our Affiliates; 7 Table of Contents • • • • our Affiliates’ ability to attract and retain client assets and market products and services, which may be impacted by investment performance, client relationships, demand for product and service offerings, their continued development of products to meet the changing demands of investors, and the prices of securities generally; global economic conditions, which may be exacerbated by changes in the equity or debt markets, including impacts from monetary policies of the U.S. Federal Reserve Bank and other global central banks in response to inflation, or instability and liquidity issues in the financial system generally; financial crises, political or diplomatic developments in the U.S. or globally, including rising trade tensions between the U.S. and China, pandemics or other public health crises, trade wars, social or civil unrest, insurrection, war, terrorism, natural disasters, or risks associated with global climate change; and other factors that are difficult to predict. A reduction in our assets under management could adversely affect the fees payable to our Affiliates and, ultimately, our financial condition and results of operations. To the extent any of these conditions or factors adversely affect our or our Affiliates’ operations or global economic conditions generally, they may also have the effect of heightening other risks described below. If our or our Affiliates’ reputations are harmed, we could suffer losses in our business and financial results. The success of our business depends on earning and maintaining the trust and confidence of our Affiliates and our stockholders, our ability to compete for future investment opportunities, and our and our Affiliates’ reputations among existing and potential clients. Our and our Affiliates’ reputations are critical to our business and could be impacted by events that may be difficult or impossible to control, and costly or impossible to remediate, including: • • • • • • • • alleged or actual failures by us, our Affiliates or our respective employees to comply with applicable laws, rules or regulations; errors in our public reports; cyber-attack or data breach incidents; fund liquidity or valuation issues including with respect to non-traded, illiquid assets within funds or products of certain of our Affiliates; threatened or actual litigation against us, any of our Affiliates or our respective employees; perceived or actual conflict between us and any of our Affiliates or among our Affiliates; negative perceptions of our or certain of our Affiliates’ investments or business practices by stakeholder groups who have increasingly expressed divergent views on a range of environmental, social, and governance (“ESG”) matters; or other events and factors that are difficult to predict including those that could impact our Affiliates’ ability to compete effectively with other firms, our ability to successfully pursue our growth strategy, and other risks described elsewhere in this “Risk Factors” section. Any of the foregoing events, or the public announcement and potential publicity surrounding these issues, even if inaccurate, satisfactorily addressed, or if no violation or wrongdoing actually occurred, could adversely impact our Affiliates’ reputations and their relationships with clients, our relationships with our Affiliates, and our ability to negotiate agreements with new independent investment firms, any of which could have an adverse effect on our reputation, our financial condition and results of operations, or the market price of our common stock. The investment management industry is highly competitive. Our Affiliates compete with numerous investment management firms globally, including public, private and client-owned investment advisers; firms managing passively-managed products, including exchange traded funds; firms associated with securities broker-dealers, financial institutions, insurance companies, private equity firms, sovereign wealth funds; and other entities. These firms may have significantly greater financial, technological, and marketing resources, captive distribution and assets under management, and many of these firms may offer products and services that our Affiliates may not in particular investment strategies. These firms may also compete by seeking to capitalize on a trend towards institutions consolidating the 8 Table of Contents number of investment managers they work with. Competition from these firms may reduce the fees that our Affiliates can obtain for investment management services, or could impair our Affiliates’ ability to attract and retain client assets, and any failure by our Affiliates to successfully develop competing new products and services, or effectively manage the associated operational risks, could harm our Affiliates’ reputations and expose them to additional costs or regulatory scrutiny, which could adversely affect our assets under management, financial condition and results of operations. We believe that our Affiliates’ ability to compete effectively with other firms depends upon the performance of our Affiliates’ investment strategies, the applicability of products to meet client objectives and preferences, and the continued development of strategies and products to meet the evolving needs and demands of investors, as well as our Affiliates’ reputations, client relationships, fee structures, client-servicing capabilities, and the marketing and distribution of their investment strategies, among other factors. See “Competition” in Item 1. Our Affiliates may not compare favorably with their competitors in any or all of these categories, and technological developments, including financial applications and services based on artificial intelligence (“AI”), may over time reduce the demand for, or clients’ willingness to pay for, certain products and services. From time to time, our Affiliates may also compete with each other for clients and investment opportunities. Investment management contracts are subject to termination on short notice. Through our Affiliates, we derive almost all of our asset- and performance-based fees from clients pursuant to investment management contracts. While certain of our Affiliates’ private equity and alternative products have long-term commitment periods, many of our Affiliates’ investment management contracts are terminable by the client without penalty upon relatively short notice (typically not longer than 60 days). We cannot be certain that our Affiliates will be able to retain their existing clients or attract new clients. If our Affiliates’ clients terminate their investment management contracts or withdraw a substantial amount of assets, it is likely to harm our results of operations. In addition, investment management contracts with mutual funds or other similar products are subject to annual approval by the fund’s board of directors. Valuation methodologies for assets within private markets funds, liquid alternatives, and similar products of certain of our Affiliates can be subject to significant subjectivity. Certain of our Affiliates offer private markets, liquid alternative, and other strategies that may invest in assets for which there may be no readily ascertainable market prices available on a regular basis or at all. In addition, many of these investments are, or may in the future be, concentrated in industries or sectors that could experience volatility or uncertainties, and may be subject to rapid changes in value caused by company-specific or industry- wide developments. The determination of the net asset values for these funds, therefore, takes a range of factors into consideration in applying valuation methodologies, and may reflect estimates or valuation models of independent third parties. These valuation methodologies require the use of estimates and assumptions, and involve a significant degree of judgment and, accordingly, the fair values of such investments reflected in a particular fund or product’s net asset value do not necessarily reflect the prices that would be obtained if the assets were to be liquidated on the date of the valuation, or on the date when an investor purchases, redeems or otherwise transacts in the fund or product, and may differ significantly from the prices obtained when such investments are ultimately realized. These factors could result in reduced earnings or losses for the applicable Affiliate, fund, or product, increase liquidity management risks for the fund or product, or result in difficulties in raising additional capital or launching similar products, any of which could have an adverse effect on our reputation, our financial condition and results of operations, or the market price of our common stock. We may need to raise additional capital in the future, and existing or future resources may not be available to us in sufficient amounts or on acceptable terms. While we believe that our existing cash resources and cash flow from operations will be sufficient to meet our working capital needs for normal operations for the foreseeable future, our continuing acquisitions of interests in independent investment firms and our other strategic initiatives may require additional capital. Further, we have significant purchase obligations relating to Affiliate equity interests, as well as commitments relating to general partner and seed capital investments, and it is difficult to predict the frequency and magnitude of these purchases or associated capital calls. As of December 31, 2023, the current redemption value relating to Affiliate equity interests was $447.3 million, of which $393.4 million was presented as Redeemable non- controlling interests (including $11.8 million of consolidated Affiliate sponsored investment products primarily attributable to third-party investors), and $53.9 million was included in Other liabilities. See “Liquidity and Capital Resources-Affiliate Equity” in Item 7 and Notes 16 and 17 of the Consolidated Financial Statements. Unfunded commitments relating to general partner and seed capital investments were $187.2 million as of December 31, 2023. See Notes 3 and 7 of the Consolidated Financial Statements. These obligations may require more cash than is then available from our existing cash resources and cash flows from operations. Thus, we may need to raise capital through additional borrowings or by selling shares of our common stock or other equity or debt securities, or otherwise refinance a portion of these obligations. 9 Table of Contents As of December 31, 2023, we had outstanding debt of $2.6 billion. Our level of indebtedness may increase if we fund future investments or other expenses through borrowings. We may also seek to refinance existing indebtedness for the purpose of managing maturity dates, to seek alternative financing terms or for other reasons, which may not be available on similar terms as our existing indebtedness, including with respect to interest rates. Any additional indebtedness could increase our vulnerability to general adverse economic and industry conditions and may require us to dedicate a greater portion of our cash flows from operations to payments on our indebtedness. The financing activities described above could increase our Interest expense, decrease our Net income (controlling interest) or dilute the interests of our existing stockholders. In addition, our access to additional capital, and the cost of capital we are able to access, is influenced by a number of factors, including the state of global credit and equity markets, interest rates, credit spreads and our credit ratings. As a result, we may be unable to enter into new credit facilities or issue debt or equity in the future on attractive terms, or at all. We are currently rated A3 by Moody’s Investors Service and BBB+ by S&P Global Ratings. A reduction in our credit ratings could also increase our borrowing costs under our credit facilities or, in certain cases, give rise to a termination right by the counterparty under our derivative financial instruments. There can be no assurance that we will achieve a particular credit rating or maintain any particular rating in the future. Our debt agreements impose certain covenants relating to the conduct of our business, including financial covenants under our credit facilities, any breach of which could result in the acceleration of the repayment of any amounts borrowed or outstanding thereunder. Our debt agreements contain customary affirmative operating covenants and negative covenants that, among other things, place certain limitations on our and our subsidiaries’ ability to incur debt, merge or transfer assets, and create liens and, in the case of our credit facilities, require us to maintain specified financial ratios, including a maximum leverage ratio and a minimum interest coverage ratio. The breach of any covenant (either due to our actions or omissions or, in the case of financial covenants, due to a significant and prolonged market-driven decline in our operating results) could result in a default under the applicable debt agreement and, in the case of our credit facilities, lenders could refuse to make further extensions of credit to us. Further, in the event of certain defaults, amounts borrowed under our debt agreements, together with accrued interest and other fees, could become immediately due and payable. If any indebtedness were to become subject to accelerated repayment, we may not have sufficient liquid assets to repay such indebtedness in full. We have substantial intangibles on our balance sheet, and any impairment of our intangibles could adversely affect our financial condition and results of operations. As of December 31, 2023, our total assets were $9.1 billion, of which $4.3 billion were intangibles, and $2.3 billion were equity method investments in Affiliates, an amount primarily composed of intangible assets. We cannot be certain that we will realize the value of such intangible assets. Our intangible assets may become impaired as a result of any number of factors, including changes in market conditions, declines in the value of assets under management, client attrition, product performance, reductions in fee rates, and changes in strategic objectives or growth prospects of an Affiliate. An impairment of our intangible assets or an other-than-temporary decline in the value of our equity method investments could adversely affect our financial condition and results of operations. Determining the value of intangible assets, and evaluating them for impairment, requires management to exercise significant judgment. In recent periods, we have recorded expenses to reduce the carrying value to fair value of certain Affiliates and certain acquired client relationships, and may experience similar impairment events in future reporting periods. See “Critical Accounting Estimates and Judgments” in Item 7 and Notes 8 and 9 of the Consolidated Financial Statements. Market risk management activities may adversely affect our liquidity and results of operations. Cash management transactions, capital markets financings, and certain investments or other transactions may create exposure for us or our Affiliates to changes in interest rates, foreign currency exchange rates, marketable securities, and financial markets generally, which we or our Affiliates may seek to offset by entering into derivative financial instruments. The scope of these risk management activities is selective and varies based on the level and volatility of interest rates, foreign currency exchange rates, applicable marketable securities, and other changing market conditions. We and our Affiliates do not seek to hedge exposure to all market risks, which means that exposure to certain market risks is not limited. Further, the use of derivative financial instruments does not entirely eliminate the possibility of fluctuations in the value of the underlying position or prevent losses if the value of the position declines, and also can limit the opportunity for gain if the value of the position increases. There can be no assurance that our or our Affiliates’ derivative financial instruments will meet their overall objective or that we or our Affiliates will be successful in entering into such instruments in the future. Further, while hedging arrangements may reduce certain risks, such arrangements themselves may entail other risks, may generate significant 10 Table of Contents transaction costs, and may require the posting of cash collateral. For example, if our or our Affiliates’ counterparties fail to honor their obligations in a timely manner, including any obligations to return posted collateral, our liquidity and results of operations could be adversely impacted. RISKS RELATED TO OUR STRATEGY AND OUR STRUCTURED PARTNERSHIPS WITH AFFILIATES Our growth strategy depends in part upon our ability to make investments in independent investment firms and to pursue other strategic partnerships. Our continued success in investing in independent investment firms will depend upon our ability to find suitable firms in which to invest or make additional investments in our existing Affiliates, our ability to negotiate agreements with such firms on acceptable terms, maintaining our relationships with prospects and our reputation as a leading partner to these firms, and our ability to raise the capital necessary to finance such transactions. The market for acquisitions of interests in these firms is highly competitive. Many other public and private financial services companies, including commercial and investment banks, private equity firms, sovereign wealth funds, insurance companies, and investment management firms, also invest in independent investment firms and may have significantly greater resources than we do. In addition to direct competition on particular prospects, these firms can also negatively impact the volume and value of transactions more broadly. Further, our innovative partnership approach with our Affiliates is designed to enhance our Affiliates’ ability to achieve their long-term strategic objectives, while preserving their independence and autonomy, and, therefore, their unique entrepreneurial and investment-centric cultures, and the management of some target firms may prefer terms and structures offered by our competitors. We may not be successful in making investments in new firms or maintaining existing investments, and any firms that we do invest in may not have favorable results or performance following our initial investment or any subsequent investment, which could have an adverse effect on our financial condition and results of operations. Our investments involve a number of risks, including the existence of unknown liabilities that may arise after making an investment, some of which may depend upon factors that are not under our control. Further, the consummation of our announced investments is generally subject to a number of closing conditions, contingencies and approvals, including, but not limited to, obtaining certain consents of the independent investment firm’s clients and applicable regulatory approvals. In the event that an announced transaction is not consummated, we may experience a decline in the price of our common stock. Our growth strategy also includes pursuing strategic partnerships and transactions in areas where we can assist our Affiliates in growing and diversifying their businesses to further enhance our competitive position, which may involve new operational areas, product structures or strategies, and expanding the geography and scope of our operations. These initiatives involve risks and uncertainties and may require resources and investment, including the implementation of new operational controls and procedures, compliance with additional regulatory and disclosure requirements, exposure to more volatile market segments and reputational risks, and require complex contractual arrangements and specialized skills, and there is no certainty that such initiatives will deliver the anticipated benefits over the expected time frame or at all, or that our stockholders will react favorably. Any failure to successfully execute on strategic partnerships or transactions, including in connection with our entry into new operational areas or effectively managing associated risks, could harm our reputation and expose us to additional costs, which could adversely affect our assets under management, financial condition, and results of operations. The structure of our partnership interests in our Affiliates may expose us to unanticipated changes in Affiliate revenue, operating expenses, and other commitments, which we may not anticipate and may have limited ability to control. The form of our structured partnership interests in our Affiliates differs from Affiliate to Affiliate, and ranges from structures where we contractually share in the Affiliate’s revenue without regard to expenses, comprising Affiliates that contribute a majority of our Consolidated revenue, to others where we contractually share in the Affiliate’s revenue less agreed-upon expenses. Further, the structure at a particular Affiliate, or the expenses that we agree to share in, may change during the course of our investment. Where we share in the Affiliate’s revenue without regard to expenses, the Affiliate allocates a specified percentage of its revenue to us and Affiliate management, while using the remainder for operating expenses and additional distributions to Affiliate management. In these types of structures, while our distributions generally have priority, our agreed allocations may not anticipate changes in the revenue and operating expense base of the Affiliate, and the revenue remaining after our specified share is allocated to us may not be large enough to cover all of the Affiliate’s operating expenses, which could result in a reduction of the amount allocated to us or could negatively impact the Affiliate’s operations and prospects. 11 Table of Contents Where we share in the Affiliate’s revenue less agreed-upon expenses, we benefit from any increase in revenue or any decrease in the agreed-upon expenses, but also have exposure to any decrease in revenue or any increase in such expenses. The degree of our exposure to agreed-upon expenses from these structured partnership interests varies by Affiliate and includes several Affiliates in which we fully share in the expenses of the business. In these types of structures, we may have limited or no ability to control the level of expenses at the Affiliate, and our distributions generally do not have priority. Further, the impact of Affiliate expenses on our earnings and our stock price could increase if the portion of our earnings derived from such Affiliates increases. As a result of these factors, unanticipated changes in revenue, operating expenses, or other commitments at any of our Affiliates could leave the Affiliate with a shortfall in remaining funds for distribution to us or Affiliate management, or for funding their operations. Changes in the global marketplace in particular could result in rapid changes to our Affiliates’ earnings or expenses, and our Affiliates may be unable to make appropriate expense reductions in a timely manner to respond to such changes. Any of these developments could have an adverse effect on our financial condition generally, and on our results of operations for the applicable reporting period. Additionally, regardless of the particular structure, we may agree to change the structure, or may elect to defer or forgo the receipt of our share of an Affiliate’s revenue or earnings, or adjust expenses allocated to us, to permit the Affiliate to fund expenses in light of unanticipated changes in revenue or operating expenses, with the aim of maximizing the long-term benefits for us and the Affiliate. These types of activities could increase during periods where an Affiliate’s revenues decline rapidly or other events occur that impact the Affiliate’s expenses or operations. We cannot be certain that any such deferral or forbearance would be of any greater long-term benefit to us, and such a deferral or forbearance may have an adverse effect on our near- or long- term financial condition and results of operations. We may reposition or divest our equity interests in our Affiliates, and we cannot be certain that any such repositioning or divestment will benefit us in the near- or long-term. From time to time, we may reposition our relationships with our Affiliates, which could, among other things, include changes to our structured partnership interests, including changes in our ownership level and in the calculation of our share of revenue and/or operating expenses. Such repositioning may be done in order to address an Affiliate’s succession planning, changes in its revenue or operating expense base, our or the Affiliate’s strategic planning, or other developments. Any repositioning of our interest in an Affiliate may result in increased exposure to changes in the Affiliate’s revenue and/or operating expenses, or in additional investments or commitments from us, or could increase or reduce, or change the structure of, our interest in the Affiliate. In some cases, this could result in the full divestment of our interest to Affiliate management or to a third-party, or in our acquisition of all of the equity interests of the Affiliate. In addition, certain of our Affiliates have customary rights in certain circumstances to restructure or sell their interests in their firm to a third-party, which could be through a direct majority or minority sale transaction, a private or public offering, or otherwise, and to cause us to participate in such restructuring or sale, which could be on terms that we view as less favorable than an alternative transaction or to retaining our interest. Any such transactions or changes, or disputes in relation to such transactions or changes which do not resolve in our favor, could have an adverse impact on our reputation, financial condition, and results of operations. We and our Affiliates rely on certain key personnel and cannot guarantee their continued service. We depend on the efforts of our executive officers and our other officers and employees. Our executive officers, in particular, play an important role in the stability and growth of our existing Affiliates and in identifying potential investments in independent investment firms. There is no guarantee that these executive officers will remain with the Company. We do not have employment agreements with our executive officers, although each has a significant deferred equity interest in the Company and is subject to non-solicitation and non-competition restrictions that may be triggered upon their departure. Further, we seek to attract and retain our key officers and employees through a number of initiatives and programs, including developing a strong values- based culture, a commitment to career development, employee engagement, attractive compensation and benefits programs, attention to succession planning, and fostering of diversity and inclusion, any of which may not be successful in contributing to the retention of such employees. Changes in our management team, in particular, may be disruptive to our business, and failure to attract and retain members of our executive or senior management team, or to effectively implement and manage appropriate succession plans, could adversely affect our business, financial condition, and results of operations. In addition, our Affiliates depend heavily on the services of key principals who, in many cases, have managed their firms for many years. These principals often are primarily responsible for their firm’s investment decisions. Although we use a combination of economic incentives, transfer restrictions and, in some instances, non-solicitation, non-competition, and 12 Table of Contents employment agreements in an effort to retain key Affiliate personnel, there is no guarantee that these principals will remain with their firms or refrain from competing with us if they depart their firms. Since certain of our Affiliates contribute more significantly to our results than other Affiliates, the loss of key personnel at these Affiliates could have a disproportionately adverse impact on our business, financial condition, and results of operations. RISKS RELATED TO OUR COMMON STOCK Equity markets and our common stock have been volatile. The market price of our common stock has experienced and may continue to experience volatility, and the broader equity markets have experienced and may continue to experience significant price and volume fluctuations. In addition, announcements of our financial and operating results or other material information, including changes in net client cash flows and assets under management, announcements and activity regarding our share repurchase programs, changes in our financial guidance or our failure to meet such guidance, our new investments activity, changes in general conditions in the economy or the financial markets, perceptions regarding our ESG profile or sustainable investment decisions of our Affiliates, and other developments affecting us, our Affiliates or our competitors, as well as geopolitical, social, regulatory, capital markets, economic, public health, and other factors unrelated to us, could cause the market price of our common stock to fluctuate substantially. The sale or issuance of substantial amounts of our common stock, or the expectation that such sales or issuances will occur, could adversely impact the price of our common stock. The sale or issuance of substantial amounts of our common stock in the public market could adversely impact its price. In connection with our financing activities, we have issued junior convertible trust preferred securities and maintain an equity distribution program, either of which may result in the issuance of our common stock upon the occurrence of certain events. We also have outstanding option and restricted stock awards that have been granted under our share-based incentive plans. Additionally, we have the right to settle certain Affiliate equity purchase obligations with shares of our common stock. Moreover, in connection with future financing activities, we may issue additional convertible securities or shares of our common stock, including through forward equity transactions. Any such issuance of shares of our common stock could have the effect of substantially diluting the interests of our current equity holders. In the event that a large number of shares of our common stock are sold or issued in the public market, or the expectation that such sales or issuances will occur, the price of our common stock may decline as a result. Provisions in our organizational documents, Delaware law, and other factors could delay or prevent a change in control of the Company, or adversely affect our financial results in periods prior to and following a change in control. Provisions in our charter and by-laws and anti-takeover provisions under Delaware law could discourage, delay, or prevent an unsolicited change in control of the Company. These provisions may also have the effect of making it more difficult for third parties to replace our executive officers without the consent of our Board of Directors. These provisions include: • • • the ability of our Board of Directors to issue preferred stock and to determine the terms, rights, and preferences of the preferred stock without stockholder approval; the prohibition on the right of stockholders to call meetings or act by written consent and limitations on the right of stockholders to present proposals or make nominations at stockholder meetings; and legal restrictions on mergers and other business combinations between us and any holder of 15 percent or more of our outstanding common stock. Further, given our long-term innovative partnership approach with our Affiliates, which is designed to maintain their independence and autonomy, and, therefore, their unique entrepreneurial and investment-centric cultures, a change in control may be viewed negatively by our Affiliates, impacting their relationships with us. Additionally, the disposition of certain of our Affiliates following a change in control could result in the immediate realization of taxes owed on any excess proceeds above our tax basis in the relevant Affiliate, which could impact the valuation a third-party may apply to us in a change in control. Any of the forgoing factors may inhibit a change in control in circumstances that could give our stockholders the opportunity to realize a premium over the market price of our common stock, or may result in negative impacts on our financial results in periods prior to and following a change in control. 13 Table of Contents In addition, a change in control of the Company or the acquisition of a large ownership position in shares of our outstanding common stock by a single holder may constitute a change in control for certain of our Affiliates for purposes of the Advisers Act and the Investment Company Act. In that case, absent client consents, the Affiliate’s management agreements may be deemed to be “assigned” in violation of the agreement and, for mutual fund clients, will terminate. We cannot be certain that any required client consents (which the impacted Affiliates would need to be involved in requesting) would be obtained if such a change of control occurs. Any termination, deemed assignment or renegotiation of any of our Affiliates’ management agreements could result in a reduction in our assets under management or the fees payable to our Affiliates and, ultimately, our aggregate fees. Further, certain of our Affiliates operate regulated businesses in jurisdictions outside of the U.S. that, in some cases, require regulatory notifications and other filings if a single stockholder acquires an ownership position in the Company exceeding certain specified thresholds, regardless of whether a change in control has occurred for purposes of the Advisers Act or the Investment Company Act. Such an ownership position could also trigger approvals under FINRA, for Affiliates operating a broker-dealer in the U.S. As a result, a large ownership position in our stock, whether or not resulting in a change of control of the Company, could result in increased regulatory reporting and compliance costs, and potential restrictions on our or our Affiliates’ business activities, and could reduce the fees that our Affiliates receive under investment management contracts, any of which could have an adverse effect on the Company’s financial condition and results of operations. LEGAL AND REGULATORY RISKS Our and our Affiliates’ businesses are highly regulated. Our and our Affiliates’ businesses are subject to complex and extensive regulation by regulatory and self-regulatory authorities and exchanges in various jurisdictions around the world, which, for our Affiliates and our U.S. wealth distribution subsidiary, include those applicable to investment advisers, as detailed in “Government Regulation” in Item 1. Applicable laws, rules and regulations impose requirements, restrictions, and limitations on our and our Affiliates’ businesses, and can result in significant compliance costs. Further, this regulatory environment may be altered without notice by new laws or regulations, revisions to existing laws or regulations, or new or revised interpretations, guidance or enforcement priorities. Any determination of a failure to comply with applicable laws, rules or regulations could expose us, our Affiliates, or our respective employees to civil liability, criminal liability, or disciplinary or enforcement action, with penalties that could include the disgorgement of fees, fines, sanctions, suspensions, termination of adviser status, or censure of individual employees or revocation or limitation of business activities or registration, and may result in monetary losses that are not covered by insurance in adequate amounts or at all, any of which could have an adverse impact on our stock price, financial condition, and results of operations. Further, if we, any of our Affiliates or our respective employees or third-party service providers were to fail to comply with applicable laws, rules, or regulations, or be named as a subject of an investigation or other regulatory action, the public announcement and potential publicity surrounding any such investigation or action could have an adverse effect on our or our Affiliates’ reputations and on our stock price and result in increased costs, even if we, our Affiliates, or our respective employees or third-party service providers were found not to have violated such laws, rules or regulations. Recently implemented and proposed regulations globally have called for more stringent oversight of the financial services industry in which we and our Affiliates operate. In the U.S., the presidential administration has actively pursued an expanded scope of enforcement priorities under existing regulations, and has been pursuing additional rulemaking and disclosure obligations, impacting public companies and the financial services industry, including private and public funds. These and other regulatory developments could adversely affect our and our Affiliates’ businesses, increase compliance costs, require that we or our Affiliates change or curtail operations or investment offerings, or impact our and our Affiliates’ access to capital and the market for our common stock. Further, in recent years, regulators in the U.S., the UK, and other jurisdictions have expanded rules and devoted greater resources and attention to the enforcement of anti-bribery and anti-money laundering laws, and while we and our Affiliates have developed and implemented policies and procedures designed to comply with these rules, such policies and procedures may not be effective in all instances to prevent violations. Our and our Affiliates’ international operations are subject to foreign risks, including political, regulatory, economic, and currency risks. We and certain of our Affiliates conduct business outside the U.S., and a number of our Affiliates are based or have offices outside the U.S. and, accordingly, are subject to risks inherent in doing business internationally. These risks may include difficulties in staffing and managing foreign operations, longer payment cycles, difficulties in collecting investment advisory fees receivable, different (and in some cases less stringent) legal, regulatory and accounting regimes, political instability, 14 Table of Contents exposure to fluctuations in currency exchange rates, expatriation controls, expropriation risks, and potential adverse tax consequences. For example, regulations in the European Union (the “EU”) pertaining to integrating ESG topics may materially impact the investment management industry in member states that have adopted, or may in the future adopt, such legislation. For example, the EU’s Sustainable Finance Disclosure Regulation requires MiFID firms and AIFMs to take ESG factors into account in their organizational, risk and governance arrangements and are designed to, among other things, establish EU labels for green financial products, clarify managers’ duties regarding sustainability in their investment decisions, and increase disclosure requirements relating to ESG matters including those relating to “greenwashing” (i.e., the holding out of a product as having green or sustainable characteristics where this is not, in fact, the case). Similar regulatory measures have been, and may in the future be, introduced in other jurisdictions in which we or our Affiliates currently have investments or plan to invest in the future, including in the U.S. and the UK, as applicable. These types of ESG- related regulations could impact our or our Affiliates’ businesses, increase regulatory and compliance costs, and adversely affect our profitability, which effects could be exacerbated in the event of regulatory uncertainty or conflicting or inconsistent regulatory guidance related thereto. In addition, as a result of operating internationally, certain of our Affiliates and our global capital distribution platform are subject to requirements under foreign regulations to maintain minimum levels of capital. Such capital requirements may be increased from time to time, which may have the effect of limiting withdrawals of capital and the payment of distributions to us or, if there were a significant change in the required capital or an extraordinary loss or charge against net capital at a particular Affiliate, could adversely impact such Affiliate’s ability to expand or maintain operations. These or other risks related to our and our Affiliates’ international operations may have an adverse effect on our business, financial condition, and results of operations. Changes in tax laws or exposure to additional tax liabilities could have an adverse impact on our business, financial condition, and results of operations. We are subject to income taxes as well as non-income based taxes in the U.S. and certain foreign jurisdictions, and our Affiliates are generally subject to taxes in the jurisdictions in which they operate. Tax laws, regulations and administrative practices in these jurisdictions may be subject to significant change, with or without notice, and significant judgment is required in estimating and evaluating tax provisions and accruals. Our and our Affiliates’ effective tax rates could be affected by a change in the mix of earnings with differing statutory tax rates, changes to our or their existing businesses, and changes in relevant tax, accounting or other laws, regulations, administrative practices, and interpretations. If new tax reform proposals are introduced in the U.S., they could materially impact our tax provision, deferred tax assets, tax liabilities, tax credit planning, and effective tax rate, or impact decisions on how to return value to stockholders in the most efficient manner. Further, a portion of our earnings is from outside of the U.S., and the foreign government agencies in jurisdictions in which we and our Affiliates do business continue to focus on the taxation of multinational companies, and could implement changes to their tax laws. For example, in October 2021, the Organization for Economic Co-operation and Development (“OECD”) agreed to a two-pillar approach to global taxation focusing on global profit allocation, referred to as Pillar One, and a global minimum corporate tax rate (“Pillar Two”). In December 2022, the EU agreed to implement the OECD’s global minimum corporate tax rate of 15% under Pillar Two, effective January 2024. Other countries, including jurisdictions in which we or our Affiliates do business, are also considering changes to their tax laws to adopt certain portions of the OECD’s proposals. Any changes to federal, state or foreign tax laws, regulations, accounting standards or administrative practices, or the release of additional guidance, interpretations or other information, including in connection with Pillar Two or otherwise, could impact our estimated effective tax rate and overall tax expense, as well as our earnings estimates, and could result in adjustments to our treatment of deferred taxes, including the realization or value thereof, or in unanticipated additional tax liabilities, any of which could have an adverse effect on our business, financial condition, and results of operations. In addition, we and our Affiliates may be subject to tax examinations by certain federal, state, and foreign tax authorities. We regularly assess the likely outcomes of examinations that we are subject to, in order to determine the appropriateness of our tax provision; however, tax authorities may disagree with certain positions we have taken or may take, and may assess additional taxes and/or penalties and interest. In the U.S., the Inflation Reduction Act included significant budget increases for tax audit and enforcement, and similar trends have developed in foreign jurisdictions. There can be no assurance that we will accurately predict the outcomes of any examinations and the actual outcomes could have an adverse impact on our financial condition and results of operations. We or our Affiliates may be involved in legal proceedings and regulatory matters from time to time, and we may be held responsible for liabilities incurred by certain of our Affiliates. Our operating agreements with our Affiliates provide for governance structures that give Affiliate management the authority to manage and operate their businesses on a day-to-day basis, including investment management operations, marketing, product development, client relationships, employee matters, compensation programs, and compliance activities. As 15 Table of Contents a consequence, our financial condition and results of operations may be adversely affected by problems stemming from the day-to-day operations of our Affiliates that we are not involved in, and where weaknesses or failures in internal processes or systems, legal or regulatory matters, or other operational challenges could lead to a disruption or cessation of our Affiliates’ operations, liability to their clients, exposure to claims or disciplinary action, or reputational harm. Certain of our Affiliates are limited liability companies or limited partnerships (or equivalent non-U.S. forms) of which we, or entities controlled by us, are the managing member or general partner (or equivalent). Consequently, to the extent that any of these Affiliates incur liabilities or expenses that exceed their ability to pay for them, we may be directly or indirectly liable for their payment. Similarly, an Affiliate’s payment of distributions to us may be subject to claims by potential creditors, and an Affiliate may default on distributions that are payable to us. In addition, with respect to each of these Affiliates, we may be held liable in some circumstances as a control person for the acts of the Affiliate or its employees. Further, we also conduct distribution, sales, and marketing activities through our U.S. wealth and global distribution platforms to extend the reach of our Affiliates’ own business development efforts, and any liability arising in connection with these activities, whether as a result of our own actions or the actions of our participating Affiliates or third-party service providers, could result in direct liability to us. Accordingly, we and our Affiliates may face various claims, litigation, or complaints from time to time, and we cannot predict the eventual outcome of such matters, some of which may be resolved in a manner unfavorable to us or our Affiliates, or whether any such matters could become material to a particular Affiliate or us in any reporting period. See “Legal Proceedings” in Item 3. While we and our Affiliates maintain errors and omissions and general liability insurance in amounts believed to be adequate to cover potential liabilities, we cannot be certain that we or our Affiliates will not have claims or related expenses that exceed the limits of available insurance coverage, that the insurers will remain solvent and will meet their obligations to provide coverage, or that insurance coverage will continue to be available to us and our Affiliates with sufficient limits and at a reasonable cost. Any legal proceedings or regulatory matters that we or our Affiliates are subject to could, whether with or without merit, be time consuming and expensive to defend and could divert management attention and resources, and could result in judgments, findings, settlements, or allegations of wrongdoing that could adversely affect our or their reputation, current and future business relationships, and our financial condition and results of operations. Our or our Affiliates’ controls and procedures and risk management policies may be inadequate, fail or be circumvented, and operational risk could adversely affect our or our Affiliates’ reputation and financial position. We and our Affiliates have adopted various controls, procedures, policies, and systems to monitor and manage risk in our and their businesses. While we currently believe that our and our Affiliates’ operational controls are effective, we cannot provide assurance that those controls, procedures, policies, and systems will always be adequate to identify and manage the internal and external risks in our and our Affiliates’ various businesses. Furthermore, we or our Affiliates may have errors in business processes or fail to implement proper procedures in operating our respective businesses, which may expose us or our Affiliates to risk of financial loss or failure to comply with regulatory requirements. Additionally, although we and our Affiliates have systems and practices in place to monitor our respective third-party service providers, such third parties are subject to similar risks. We and our Affiliates, as well as our respective third-party service providers, are also subject to the risk that employees or contractors, or other third parties, may deliberately seek to circumvent established controls to commit fraud or act in ways that are inconsistent with our or their controls, policies, and procedures, and which may be harder to monitor in remote work environments. The financial and reputational impact of control failures can be significant. In addition, our and our Affiliates’ businesses and the markets in which we and our Affiliates operate are continuously evolving. For example, the use of generative AI technologies by us, our Affiliates, or our respective third-party service providers could result in new and expanded risks. If our or our Affiliates’ risk frameworks are ineffective, either because of a failure to keep pace with changes in the financial markets, technological advancements, or regulatory requirements, our or our Affiliates’ businesses, counterparties, clients, or respective third-party service providers, or for other reasons, we or our Affiliates could incur losses, suffer reputational damage, or be out of compliance with applicable regulatory or contractual mandates or expectations. Failure to maintain and properly safeguard an adequate technology infrastructure may limit our or our Affiliates’ growth, result in losses or disrupt our or our Affiliates’ businesses. Our and our Affiliates’ businesses are reliant upon financial, accounting, and technology systems and networks to process, transmit, and store information, including sensitive client and proprietary information, and to conduct many business activities and transactions with clients, advisers, regulators, vendors, and other third parties. The failure to implement, maintain, and safeguard an infrastructure commensurate with the size and scope of our and our Affiliates’ businesses could impede productivity and growth, which could adversely impact our financial condition and results of operations. Further, we and our Affiliates rely on third parties for certain aspects of our respective businesses, including financial intermediaries, providers of 16 Table of Contents technology infrastructure, and other service providers such as broker-dealers, custodians, administrators and other agents, as well as accounting, legal, and other professional advisors, and these parties are susceptible to similar risks. Our computer systems, software, internal and cloud-based networks, and mobile devices are vulnerable to cyber-attacks, data privacy or security breaches, phishing schemes and related fraud attempts, ransomware, social engineering, unauthorized access, theft, misuse, computer viruses, or other malicious code and other events that could have a security impact. Any such cyber-attacks could have a material impact on our financial conditions or results of operations. Further, third parties on whom we and our Affiliates rely, including those providing cloud-based network services, may have similar vulnerabilities and may lack the necessary infrastructure or resources, or may otherwise fail, to adequately protect against or respond to any cyber-attacks, data breaches, or other incidents. If any such events occur, it could jeopardize confidential, proprietary, or other sensitive information of ours, our Affiliates and our respective clients, employees or counterparties that may be stored in, or transmitted through, internal or third-party computer systems, networks, and mobile devices, or could otherwise cause interruptions or malfunctions in our and our Affiliates’ operations or those of our respective clients or counterparties, or in the operations of third parties on whom we and our Affiliates rely. The advancement of AI has given rise to additional vulnerabilities and potential entry points for cyber threats, providing threat actors with additional tools to automate attacks, evade detection, or generate sophisticated phishing emails. Despite efforts to ensure the integrity of systems and networks, it is possible that we, our Affiliates or our respective third-party service providers may not be able to anticipate or to implement effective preventive measures against all threats, especially because the techniques used change frequently and can originate from a wide variety of sources. Further, human errors may occur from time to time at our third-party service providers’ staff or among our or our Affiliates’ employees, which can lead to or exacerbate security vulnerabilities or attacks. The increasing frequency and sophistication of these cyber threats, including in foreign jurisdictions in which we and our Affiliates operate, along with the continued reliance on work-from-home environments, personal mobile and computing technologies, and third-party web conferencing services, have increased exposures to these security-related risks. As a result, we or our Affiliates could experience disruption, significant losses, increased costs, reputational harm, regulatory actions, or legal liability, any of which could have an adverse effect on our financial condition and results of operations. We or our Affiliates may be required to spend significant additional resources to modify protective measures or to investigate and remediate vulnerabilities or other exposures, and may be subject to litigation, regulatory investigations, and potential fines, and financial losses that are either not insured against fully or not fully covered through any insurance that we or our Affiliates maintain. Additionally, given our business model of providing our Affiliates with autonomy in managing their businesses, we do not control, and may have limited involvement in, the design, oversight, and maintenance of their technology systems and networks, as well as in the identification of or response to any cyber-attacks, data breaches, or other incidents. See “Cybersecurity” in Item 1C. Further, government and regulatory oversight of data privacy in particular has become a priority for regulators around the world, including as examples, through the EU’s General Data Protection Regulation and the California Privacy Rights Act, resulting in heightened data security and handling requirements, increased enforcement risk and fines, increased compliance costs, and expanded incident response and reporting obligations. More recently, the SEC has implemented new rules related to cybersecurity risk management for public companies and is expected to implement similar new rules for registered investment advisers, broker-dealers, and funds, which have resulted or may result, as applicable, in increased disclosure requirements, obligations to report certain cybersecurity incidents to the SEC, and liabilities related to our and our Affiliates’ technology systems and networks. Recent well-publicized security breaches at other companies have exemplified security-related vulnerabilities, and may lead to further government and regulatory scrutiny and heightened security requirements both in the U.S. and in other jurisdictions in which we and our Affiliates operate. Item 1B. Unresolved Staff Comments None. Item 1C. Cybersecurity Risk Management and Strategy We regularly assess risks from cybersecurity threats, monitor our information systems for potential vulnerabilities, and test those systems pursuant to our cybersecurity policies, processes, and practices. To protect our information systems from cybersecurity threats, we use various security tools that help us identify, escalate, investigate, resolve, and recover from security incidents in a timely manner. We recognize the importance of protecting information assets such as the personally identifiable information of our employees, and proprietary business information regarding our Affiliates and their clients, and have adopted policies, management oversight, accountability structures, and technology processes designed to safeguard this information. All of our 17 Table of Contents employees are required to attest annually to our information security policies and participate in regular security awareness training to protect their information and the AMG data and systems to which they have access. These trainings also instruct employees on how to report any potential privacy or data security issues. Our information security organization comprises internal and external resources designed to identify, protect, detect, mitigate, resolve, and recover from various threats and attacks by malicious actors. We leverage 24x7x365 monitoring tools and services to address the confidentiality, integrity, and availability of AMG assets and data. Regular internal and third-party reviews are performed on our processes and technologies to validate the effectiveness of our privacy and data security controls and safeguards. We monitor industry best practices and developments in data privacy and security, including increased scrutiny of third-party service providers with access to sensitive AMG data. We also have our own fully documented proprietary security incident response plan, with defined roles and responsibilities that address notification obligations and incident response procedures in the event of a data security breach. We are dedicated to business continuity and resiliency, and have documented strategies, policies, and procedures in place to protect employee, business, Affiliate, and Affiliate client data in the event of an emergency or natural disaster. Although we provide our Affiliates with operational autonomy in managing their businesses and may have limited involvement in the design, oversight, and maintenance of their respective technology systems and networks, we offer ongoing cybersecurity support to Affiliates through our information security program, including with respect to conducting Affiliate program assessments and assisting, as appropriate and practicable, in their identification of, and response to, an actual or suspected cybersecurity incident. Additionally, prior to any investment in a new Affiliate, we conduct a diligence review of its information security program. We work with third-party service providers to proactively assess our information security program and provide us with an industry view of the cyberthreat landscape, in addition to monitoring and supporting our control environment and breach notification and response processes. As of the date of this Annual Report on Form 10-K, cybersecurity threats have not materially affected and we believe are not reasonably likely to materially affect AMG, including our business strategy, results of operations, or financial condition. Refer to the risk factor captioned “Failure to maintain and properly safeguard an adequate technology infrastructure may limit our or our Affiliates’ growth, result in losses or disrupt our or our Affiliates’ businesses” in Part I, Item 1A. “Risk Factors” for more information regarding cybersecurity risks and potential related impacts on AMG. Governance We have a formal information security program, designed to develop and maintain privacy and data security practices to protect AMG assets and sensitive third-party information, including personal and Affiliate information. This program is governed by a committee comprising members of senior management, including our Chief Information Officer (“CIO”), which meets regularly and reports to the Board of Directors at least annually (the “Information Security Governance Committee”). Members of the Information Security Governance Committee oversee communications with the Board of Directors regarding material cybersecurity incidents and provide the Board with a summary of risks from current cybersecurity threats on a regular basis, as well as updates on management’s information security program oversight and maintenance activities, and any material changes to AMG’s information security practices and procedures. The Board of Directors is also regularly provided with cybersecurity educational sessions, including perspectives from external advisors that are invited to present on current cybersecurity topics. We take a risk-based approach to cybersecurity and have implemented policies throughout our operations that are designed to address cybersecurity threats and our response to actual or suspected incidents. In particular, the Information Security Governance Committee is responsible for the ongoing identification and assessment of reasonably foreseeable cybersecurity threats and based on these assessments, evaluating and overseeing the implementation of safeguards for limiting such risks, including employee training and compliance, and detection and prevention mechanisms. If a cybersecurity incident occurs, the Information Security Governance Committee will assemble an incident response team responsible for the identification, remediation, and post-incident review of such incident, engage outside advisors and notify third parties as appropriate, and assess the materiality of the nature, scope, and timing of a given incident and whether public disclosure is required. The CIO, in coordination with the Information Security Governance Committee, is responsible for leading the assessment and management of cybersecurity risks. The current CIO has over 25 years of experience in information security. The CIO reports to the Board of Directors as part of the Information Security Governance Committee’s updates discussed above and regularly communicates with the other members of the Information Security Governance Committee and senior management regarding cybersecurity risks. 18 Table of Contents Item 2. Properties We conduct our operations around the world using a combination of leased and owned facilities. While we believe we have suitable property resources currently, we will continue to evaluate our property needs and will adjust these resources as necessary. Our Affiliates also typically lease office space in the city or cities in which they conduct business, as appropriate for their respective business needs. Item 3. Legal Proceedings Governmental and regulatory authorities in the U.S. and other jurisdictions in which we and our Affiliates operate regularly make inquiries and administer examinations with respect to our and our Affiliates’ compliance with applicable laws and regulations, and from time to time, we and our Affiliates may be parties to various claims, lawsuits, complaints, regulatory investigations, and other proceedings in the ordinary course of business. Currently, there are no such claims, lawsuits, complaints, regulatory investigations, or other proceedings against us or our Affiliates that, in our opinion, would have a material adverse effect on our financial position, liquidity, or results of operations. However, there is no assurance as to whether or not any such matters could arise or have a material effect on our or our Affiliates’ financial position, liquidity, or results of operations in any future reporting period.

Management’s Discussion and Analysis of Financial Condition and Results of Operations The following executive overview, which summarizes the significant trends affecting our results of operations and financial condition, as well as the remainder of this Management’s Discussion and Analysis of Financial Condition and Results of Operations of Affiliated Managers Group, Inc. and its subsidiaries, should be read in conjunction with the “Forward-Looking Statements” section set forth in Part I, the “Risk Factors” section set forth in Item 1A of Part I and with our Consolidated Financial Statements and the notes thereto contained elsewhere in this Annual Report on Form 10-K, and in any more recent filings with the SEC. Our discussion and analysis of the key operating performance measures and financial results for fiscal year 2023 compared to fiscal year 2022 is included herein. For discussion and analysis of fiscal year 2022 compared to fiscal year 2021, please refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7 of Part II in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, which was filed with the SEC on February 17, 2023. Executive Overview AMG is a strategic partner to leading independent investment firms globally. Our strategy is to generate long-term value by investing in a diverse array of high-quality independent partner-owned firms, referred to as “Affiliates,” through a proven partnership approach, and allocating resources across our unique opportunity set to the areas of highest growth and return. With their entrepreneurial, investment-centric cultures and alignment of interests with clients through direct equity ownership by firm principals, independent firms have fundamental competitive advantages in offering unique return streams to the marketplace. Through AMG’s distinctive approach, we enhance these advantages to magnify the long-term success of our Affiliates and actively support their independence. Our innovative model enables each Affiliate’s management team to retain autonomy and significant equity ownership in their firm, while they leverage our strategic capabilities and insight, including growth capital, product strategy and development, capital formation, and incentive alignment and succession planning. As of December 31, 2023, our aggregate assets under management were approximately $673 billion across a diverse range of private markets, liquid alternatives, and differentiated long-only investment strategies. In the third quarter of 2023, we completed a minority investment in Forbion Group Holding B.V., a private markets firm focused on investing in high- quality life sciences companies, and in the fourth quarter of 2023, we completed a minority investment in Ara Partners Group, LLC, a private markets firm specializing in industrial decarbonization. Following the close of the transactions, Affiliate management continues to hold a significant majority of the equity of the businesses and directs the day-to-day operations. In the third quarter of 2023, we completed the sale of our equity interest in Veritable, LP (“Veritable”) (the “Veritable Transaction”). Pursuant to the terms of the agreement, under which a third party acquired 100% of the outstanding equity interests in Veritable, we received $287.4 million in cash, net of transaction costs. Our gain on the transaction was $133.1 million. In the fourth quarter of 2022, we completed the sale of our equity interest in Baring Private Equity Asia (“BPEA”) to EQT AB (“EQT”), a public company listed on Nasdaq Stockholm (EQT.ST), (the “BPEA Transaction”) in connection with the strategic combination of BPEA and EQT. Pursuant to the terms of the Securities Purchase and Merger Agreement with EQT, under which we and each of the other owners agreed to sell our respective equity interests in BPEA, we received $223.6 million in cash, net of transaction costs, and 28.68 million EQT ordinary shares (25% of which were subject to a six-month lock-up, which expired in April 2023), and other investments. Our gain on the transaction was $641.9 million. Operating Performance Measures Under accounting principles generally accepted in the U.S. (“GAAP”), we are required to consolidate certain of our Affiliates and use the equity method of accounting for others. Whether we consolidate an Affiliate or use the equity method of accounting, we maintain the same innovative partnership approach and provide support and assistance in substantially the same manner for all of our Affiliates. Furthermore, all of our Affiliates are investment managers and are impacted by similar marketplace factors and industry trends. Therefore, our key aggregate operating performance measures are important in providing management with a more comprehensive view of the operating performance and material trends across our entire business. The following table presents our key aggregate operating performance measures: 22 Table of Contents (in billions, except as noted) Assets under management Average assets under management Aggregate fees (in millions) As of and for the Years Ended December 31, 2021 2022 % Change 2023 % Change $ 813.8 $ 761.7 5,611.4 650.8 709.4 5,560.5 (20)% $ (7)% (1)% 672.7 660.3 5,066.6 3 % (7)% (9)% Assets under management, and therefore average assets under management, include the assets under management of our consolidated and equity method Affiliates. Assets under management is presented on a current basis without regard to the timing of the inclusion of an Affiliate’s financial results in our operating performance measures and Consolidated Financial Statements. Average assets under management reflects the timing of the inclusion of an Affiliate’s financial results in our operating performance measures and Consolidated Financial Statements. Average assets under management for mutual funds and similar investment products generally represents an average of the daily net assets under management, while for institutional and high net worth clients, average assets under management generally represents an average of the assets at the beginning or end of each month during the applicable period. Aggregate fees consist of the total asset- and performance-based fees earned by all of our consolidated and equity method Affiliates. For certain of our Affiliates accounted for under the equity method, we report the Affiliate’s aggregate fees one quarter in arrears. Aggregate fees are provided in addition to, but not as a substitute for, Consolidated revenue or other GAAP performance measures. Assets Under Management Our Affiliates provide a diverse range of differentiated return streams through their specialized investment processes. We continue to see demand for alternative strategies, as evidenced by our net inflows in this category for the year ended December 31, 2023. At the same time, our equity strategies saw outflows, particularly in global equities, in line with client cash flow trends across the industry. We continue to invest in areas of long-term client demand — including private markets, liquid alternatives, sustainable investment strategies, wealth management, and Asia — through new and existing Affiliates, to better position AMG to benefit from industry growth trends. We also anticipate that independent investment firms will continue to seek access to an evolving range of partnership solutions, and that we have a significant opportunity to invest in additional high-quality firms across the global investment management industry. The following charts present information regarding the composition of our assets under management by strategy as of December 31, 2022 and 2023: Assets Under Management by Strategy ___________________________ (1) Alternatives include private markets strategies, which accounted for 15% and 17% of our assets under management as of December 31, 2022 and 2023, respectively.

The following tables present performance of our investment strategies, where available, measured by the percentage of assets under management ahead of their relevant benchmark: (2) Liquid alternatives Global equity U.S. equity (2) Multi-asset and fixed income (2) (3) Private markets (4) ___________________________ AUM Weight % of AUM Ahead of Benchmark (1) 3-year 5-year 10-year 18 % 28 % 21 % 16 % 85 % 44 % 42 % N/A 95 % 43 % 77 % N/A 84 % 61 % 77 % N/A AUM Weight % of AUM Ahead of Benchmark (1) IRR Latest Vintage IRR Last Three Vintages 17 % 83 % 84 % (1) (2) Past performance is not indicative of future results. Performance and AUM information is as of December 31, 2023 and is based on data available at the time of calculation. Product returns are sourced from Affiliates while benchmark returns are generally sourced via third-party subscriptions. For liquid alternative, global equity, and U.S. equity products, performance is reported as the percentage of assets that have outperformed benchmarks across the indicated periods, and excludes market-hedging products. For purposes of investment performance comparisons, products are an aggregation of portfolios (separate accounts, investment funds, and other products) that each represent a particular investment objective, using the most representative portfolio for the performance comparison. Performance is presented for products with a three-, five-, and/or ten-year track record and is measured on a consistent basis relative to the most appropriate benchmarks. Benchmark appropriateness is generally reviewed annually to reflect any changes in how underlying portfolios/mandates are managed. Product and benchmark performance is reflected as total return and is annualized. Reported product performance is gross-of-fees for institutional and high-net-worth separate accounts, and generally net-of-fees across retail funds and other commingled vehicles such as hedge funds. (3) Multi-asset and fixed income products are mainly our wealth management and solutions offerings. These investment products are primarily customized toward wealth preservation, estate planning, and liability and tax management, and therefore are typically not measured against a benchmark. 25 Table of Contents (4) For private markets products, performance is reported as the percentage of assets that have outperformed benchmarks on a since-inception internal rate of return basis. Benchmarks utilized include a combination of public market equivalents, peer medians, and absolute returns where benchmarks are not available. For purposes of investment performance comparisons, the latest vintage comparison includes the most recent vehicles and strategies (traditional long-duration investment funds, customized vehicles, and other evergreen vehicles and product structures) where meaningful performance is available and calculable. In order to illustrate the performance of our private markets product category over a longer period of history, the last three vintages comparison incorporates the latest vintage vehicles and the prior two vintages for traditional long-duration investment funds, as well as additional vehicles and strategies launched during the equivalent time period as the last three vintages of traditional long-duration investment funds. Due to the nature of these investments and vehicles, reported performance is typically on a three- to six-month lag basis. Aggregate Fees Aggregate fees consist of asset- and performance-based fees of our consolidated and equity method Affiliates. Asset-based fees include advisory and other fees earned by our Affiliates for services provided to their clients and are typically determined as a percentage of the value of a client’s assets under management, generally inclusive of uncalled commitments. Asset-based fees are generally impacted by the level of average assets under management and the composition of these assets across our strategies with different asset-based fee ratios. Our asset-based fee ratio is calculated as asset-based fees divided by average assets under management. In some cases, if product returns exceed certain performance thresholds, we will participate in performance-based fees. Performance-based fees are based on investment performance, typically on an absolute basis or relative to a benchmark or hurdle rate, and are generally recognized when it is improbable that there will be a significant reversal in the amount of revenue recognized. Performance-based fees are generally billed less frequently than asset-based fees and will vary from period to period because they inherently depend on investment performance. As of December 31, 2023, approximately 27% of our total assets under management could potentially earn performance-based fees. These percentages were approximately 12% and 48% of our assets under management for our consolidated Affiliates and Affiliates accounted for under the equity method, respectively. We anticipate performance- based fees will be a recurring component of our aggregate fees; however we do not anticipate these fees to be a significant component of our Consolidated revenue as these fees are predominately earned by our Affiliates accounted for under the equity method. Aggregate fees were $5,066.6 million in 2023, a decrease of $493.9 million or 9% as compared to 2022. The decrease in our aggregate fees was due to a $348.7 million or 6% decrease from asset-based fees and a $145.2 million or 3% decrease from performance-based fees, primarily in our liquid alternative strategies. The decrease in asset-based fees was principally due to a decrease in our average assets under management, primarily in our global equity strategies, and the impact of the BPEA Transaction. These decreases were partially offset by changes in the composition of our assets under management. Financial and Supplemental Financial Performance Measures The following table presents our key financial and supplemental financial performance measures: (in millions) Net income (controlling interest) Adjusted EBITDA (controlling interest) Economic net income (controlling interest) (2) (2) For the Years Ended December 31, 2021 $ 565.7 $ 1,045.6 770.0 2022 1,145.9 1,053.8 797.2 % Change 2023 % Change N.M. (1) $ 1 % 4 % 672.9 935.7 717.8 (41)% (11)% (10)% ___________________________ (1) (2) Percentage change is not meaningful. Adjusted EBITDA (controlling interest) and Economic net income (controlling interest) are non-GAAP performance measures and are discussed in “Supplemental Financial Performance Measures.” Adjusted EBITDA (controlling interest) is an important supplemental financial performance measure for management as it provides a comprehensive view of our share of the financial performance of our business. Adjusted EBITDA (controlling interest) decreased $118.1 million or 11% in 2023, primarily due to a $493.9 million or 9% decrease in aggregate fees. Adjusted EBITDA (controlling interest) decreased more than aggregate fees on a percentage basis primarily due to the recognition of performance-based fees earned by Affiliates in which we hold less of an economic interest. 26 Table of Contents Net income (controlling interest) decreased $473.0 million or 41% in 2023. This decrease was primarily due to a $508.8 million decrease in Affiliate Transaction gains and the impact of a $58.1 million decrease in Equity method income (net). These decreases were partially offset by a $169.1 million decrease in Income tax expense attributable to the controlling interest. We believe Economic net income (controlling interest) is an important supplemental financial performance measure because it represents our performance before non-cash expenses relating to our acquisition of interests in Affiliates and improves comparability of performance between periods. Economic net income (controlling interest) decreased $79.4 million or 10% in 2023 primarily due to a $118.1 million or 11% decrease in Adjusted EBITDA (controlling interest). Results of Operations The following discussion includes the key operating performance measures and financial results of our consolidated and equity method Affiliates. Our consolidated Affiliates’ financial results are included in our Consolidated revenue, Consolidated expenses, and Investment and other income, and our share of our equity method Affiliates’ financial results is reported, net of intangible amortization and impairments, in Equity method income (net). Consolidated Revenue Our Consolidated revenue is derived from our consolidated Affiliates, primarily from asset-based fees from investment management services. For these Affiliates, we typically use structured partnership interests in which we contractually share in the Affiliate’s revenue without regard to expenses. Consolidated revenue is generally determined by the level of our consolidated Affiliates’ average assets under management and the composition of these assets across our consolidated Affiliates’ investment strategies with different asset-based fee ratios and performance-based fees. The following table presents our consolidated Affiliates’ average assets under management and Consolidated revenue: (in millions, except as noted) Consolidated Affiliate average assets under management (in billions) Consolidated revenue For the Years Ended December 31, 2021 2022 % Change 2023 % Change $ $ 445.8 $ 422.2 2,412.4 $ 2,329.6 (5)% $ (3)% $ 393.7 2,057.8 (7)% (12)% Our Consolidated revenue decreased $271.8 million or 12% in 2023, due to a $165.5 million or 7% decrease from asset-based fees and a $106.3 million or 5% decrease from performance-based fees, primarily in our private markets strategies. The decrease in asset-based fees was principally due to a decrease in consolidated Affiliate average assets under management, primarily in our global equity strategies. Consolidated Expenses Our Consolidated expenses are primarily attributable to the non-controlling interests of our consolidated Affiliates. The following table presents our Consolidated expenses: (in millions) Compensation and related expenses Selling, general and administrative Intangible amortization and impairments Interest expense Depreciation and other amortization Other expenses (net) Total consolidated expenses For the Years Ended December 31, 2021 1,047.1 $ 347.1 35.7 111.4 16.6 73.5 1,631.4 $ 2022 1,071.5 385.5 51.6 114.4 15.8 34.7 1,673.5 $ $ % Change 2023 % Change 2 % $ 11 % 45 % 3 % (5)% (53)% 3 % $ 907.5 358.2 48.3 123.8 13.0 45.8 1,496.6 (15)% (7)% (6)% 8 % (18)% 32 % (11)% Compensation and related expenses decreased $164.0 million or 15% in 2023, primarily due to a $161.9 million decrease in compensation correlated to the decrease in Consolidated revenue and a $3.0 million decrease in share-based compensation. 27 Table of Contents Selling, general and administrative expenses decreased $27.3 million or 7% in 2023, primarily due to a $26.0 million decrease in distribution and investment-related expenses principally as a result of a decrease in average assets under management on which these expenses are incurred. There were no significant changes in Intangible amortization and impairments in 2023. Interest expense increased $9.4 million or 8% in 2023, primarily due to a $12.1 million increase resulting from higher interest rates on our senior unsecured term loan facility (the “term loan”). This increase was partially offset by a $2.9 million decrease resulting from repurchases of our junior convertible securities in the first half of 2022. There were no significant changes in Depreciation and other amortization in 2023. Other expenses (net) increased $11.1 million or 32% in 2023, primarily due to a $13.0 million increase in expenses related to changes in the values of contingent payment obligations. Equity Method Income (Net) When we do not own a controlling equity interest in an Affiliate, but have significant influence, we account for our interest in the Affiliate under the equity method. Our share of earnings or losses from Affiliates accounted for under the equity method, net of amortization and impairments, is included in Equity method income (net). For certain of our Affiliates accounted for under the equity method, we report the Affiliate’s financial results in our Consolidated Financial Statements one quarter in arrears. For a majority of these Affiliates, we use structured partnership interests in which we contractually share in the Affiliate’s revenue less agreed-upon expenses. We also use structured partnership interests in which we contractually share in the Affiliate’s revenue without regard to expenses. Our equity method revenue is derived primarily from asset- and performance-based fees from investment management services. Equity method revenue incorporates the total asset- and performance-based fees earned by all of our Affiliates accounted for under the equity method and is generally determined by the level of our equity method Affiliate average assets under management and the composition of these assets across our strategies with different asset-based fee ratios and performance-based fees. Our Affiliates accounted for under the equity method manage a greater proportion of assets subject to performance-based fees than our consolidated Affiliates and, as a result, equity method revenue will generally have more performance-based fees than Consolidated revenue. The following table presents equity method Affiliate average assets under management and equity method revenue, as well as equity method earnings, equity method intangible amortization, and equity method intangible impairments, which in aggregate form Equity method income (net): (in millions, except as noted) Operating Performance Measures Equity method Affiliate average assets under management (in billions) Equity method revenue Financial Performance Measures Equity method earnings Equity method intangible amortization Equity method intangible impairments Equity method income (net) 2021 2022 % Change 2023 % Change For the Years Ended December 31, $ $ $ $ 315.9 $ 287.2 3,199.0 $ 3,230.9 (9)% $ 1 % $ 266.6 3,008.8 417.5 $ (123.0) (52.0) 242.5 $ 497.2 (109.1) (50.0) 338.1 19 % $ (11)% (4)% 39 % $ 375.6 (86.0) (9.6) 280.0 (7)% (7)% (24)% (21)% (81)% (17)% Our equity method revenue decreased $222.1 million or 7% in 2023, due to a $183.2 million or 6% decrease from asset-based fees and a $38.9 million or 1% decrease from performance-based fees, primarily in our liquid alternative strategies. The decrease in asset-based fees was principally due to the impact of the BPEA Transaction, partially offset by changes in the composition of our assets under management. 28 Table of Contents Equity method earnings decreased $121.6 million or 24% in 2023, while equity method revenue decreased $222.1 million or 7%. Equity method earnings decreased more than equity method revenue on a percentage basis primarily due to the recognition of performance-based fees earned by Affiliates in which we hold less of an economic interest. Equity method intangible amortization decreased $23.1 million or 21% in 2023, primarily due to a $22.9 million decrease in amortization expense due to a decrease in actual and expected client attrition for certain definite-lived acquired client relationships and an $8.4 million decrease due to the BPEA Transaction. These decreases were partially offset by an $8.2 million increase in amortization expense due to investments in new Affiliates. Equity method intangible impairments decreased $40.4 million or 81% in 2023. See Note 9 of our Consolidated Financial Statements. Affiliate Transaction gains For the years ended December 31, 2022, and 2023, we recorded gains of $641.9 million on the BPEA Transaction and $133.1 million on the Veritable Transaction, respectively. See Notes 8 and 9 of our Consolidated Financial Statements. Investment and Other Income The following table presents our Investment and other income: (in millions) Investment and other income For the Years Ended December 31, 2021 2022 % Change 2023 % Change $ 117.6 $ 110.3 (6)% $ 117.1 6 % Investment and other income increased $6.8 million or 6% in 2023, primarily due to a $29.2 million net increase in realized and unrealized gains on Other investments and a $21.1 million increase in interest income. These increases were partially offset by a $38.9 million net decrease in realized and unrealized gains on Investments in marketable securities. Income Tax Expense The following table presents our Income tax expense: (in millions) Income tax expense For the Years Ended December 31, 2021 2022 % Change 2023 % Change $ 251.0 $ 358.3 43 % $ 185.3 (48)% Income tax expense decreased $173.0 million or 48% in 2023, primarily due to a decrease in Income before income taxes attributable to the controlling interest and higher discrete foreign and domestic tax benefits realized on our final 2022 tax returns as a result of the change in the mix of foreign and domestic income. See Note 19 of our Consolidated Financial Statements. Net Income The following table presents Net income, Net income (controlling interest) and Net income (non-controlling interest): (in millions) Net income Net income (non-controlling interests) Net income (controlling interest) ___________________________ (1) Percentage change is not meaningful.

These decreases were partially offset by a decrease in Income tax expense attributable to the controlling interest. Supplemental Financial Performance Measures 29 Table of Contents As supplemental information, we provide non-GAAP performance measures of Adjusted EBITDA (controlling interest), Economic net income (controlling interest), and Economic earnings per share. Management utilizes these non-GAAP performance measures to assess our performance before our share of certain non-cash expenses and to improve comparability between periods. In the first quarter of 2023, we updated the definitions of Adjusted EBITDA (controlling interest) and Economic net income (controlling interest) to reflect AMG's strategic evolution, including our increased allocation of capital toward private markets and liquid alternatives. To align with the economic impact of these capital allocation decisions, the updated definitions of Adjusted EBITDA (controlling interest) and Economic net income (controlling interest): (i) include only the realized economic gains and losses on seed capital, general partner commitments, and other strategic investments and (ii) exclude any unrealized gains and losses on strategic investments (consistent with the existing treatment of seed capital and general partner commitments). We have retroactively applied this definition change to prior periods. Adjusted EBITDA (controlling interest) Adjusted EBITDA (controlling interest) is an important supplemental financial performance measure for management as it provides a comprehensive view of our share of the financial performance of our business before interest expense, income and certain non-income based taxes, depreciation, amortization, impairments, gains and losses related to the BPEA and Veritable Transactions, and non-cash items such as certain Affiliate equity activity, gains and losses on our contingent payment obligations, and unrealized gains and losses on seed capital, general partner commitments, and other strategic investments. Adjusted EBITDA (controlling interest) is also adjusted for realized economic gains and losses related to these seed capital, general partner commitments, and other strategic investments. We believe that many investors use this non-GAAP measure when assessing the financial performance of companies in the investment management industry. This non-GAAP performance measure is provided in addition to, but not as a substitute for, Net income (controlling interest) or other GAAP performance measures. The following table presents a reconciliation of Net income (controlling interest) to Adjusted EBITDA (controlling interest): (in millions) Net income (controlling interest) Interest expense Income taxes Intangible amortization and impairments Affiliate Transactions Other items (2) (3) (1) Adjusted EBITDA (controlling interest) ___________________________ For the Years Ended December 31, 2021 565.7 $ 111.4 229.6 199.9 — (61.0) 1,045.6 $ 2022 1,145.9 $ 114.4 347.4 195.0 (743.6) (5.3) 1,053.8 $ 2023 672.9 123.8 185.2 128.5 (162.7) (12.0) 935.7 $ $ (1) Intangible amortization and impairments in our Consolidated Statements of Income include amortization attributable to the non-controlling interests of our consolidated Affiliates. For our Affiliates accounted for under the equity method, we do not separately report intangible amortization and impairments in our Consolidated Statements of Income. Our share of these Affiliates’ amortization and impairments is included in Equity method income (net). The following table presents the Intangible amortization and impairments shown above: (in millions) Consolidated intangible amortization and impairments Consolidated intangible amortization and impairments (non-controlling interests) Equity method intangible amortization and impairments Total For the Years Ended December 31, 2021 2022 2023 $ $ 35.7 $ (10.8) 175.0 199.9 $ 51.6 $ (15.7) 159.1 195.0 $ 48.3 (15.4) 95.6 128.5 (2) The year ended December 31, 2022 includes BPEA Transaction gain of $641.9 million and realized and unrealized gains on EQT ordinary shares of $43.8 million and $57.9 million, respectively. The year ended December 31, 2023 includes Veritable Transaction gain of $133.1 million and realized gains on ordinary shares of EQT of $29.6 million. 30 Table of Contents (3) Other items include certain non-income based taxes, depreciation, and non-cash items such as gains and losses on our contingent payment obligations, certain Affiliate equity activity, unrealized gains and losses on seed capital, general partner commitments, and other strategic investments, and realized economic gains and losses related to these seed capital, general partner commitments, and other strategic investments. Economic Net Income (controlling interest) and Economic Earnings Per Share We believe Economic net income (controlling interest) and Economic earnings per share are important measures because they represent our performance before non-cash expenses relating to the acquisition of interests in Affiliates and improve comparability of performance between periods. Economic net income (controlling interest) and Economic earnings per share are used by our management and Board of Directors as our principal performance benchmarks, including as one of the measures for aligning executive compensation with stockholder value. These non-GAAP performance measures are provided in addition to, but not as substitutes for, Net income (controlling interest) and Earnings per share (diluted) or other GAAP performance measures. We adjust Net income (controlling interest) to calculate Economic net income (controlling interest) by adding back our share of pre-tax intangible amortization and impairments attributable to intangible assets (including the portion attributable to equity method investments in Affiliates) because these expenses do not correspond to the changes in the value of these assets, which do not diminish predictably over time. We also add back the deferred taxes attributable to intangible assets because we believe it is unlikely these accruals will be used to settle material tax obligations. Further, we adjust for gains and losses related to the BPEA and Veritable Transactions, net of tax and other economic items to improve comparability of performance between periods. Economic earnings per share represents Economic net income (controlling interest) divided by the Average shares outstanding (adjusted diluted). In this calculation, we exclude the potential shares issued upon settlement of Redeemable non-controlling interests from Average shares outstanding (adjusted diluted) because we intend to settle those obligations without issuing shares, consistent with all prior Affiliate equity purchase transactions. The potential share issuance in connection with our junior convertible securities is measured using a “treasury stock” method. Under this method, only the net number of shares of common stock equal to the value of these junior convertible securities in excess of par, if any, is deemed to be outstanding. We believe the inclusion of net shares under a treasury stock method best reflects the benefit of the increase in available capital resources (which could be used to repurchase shares of common stock) that occurs when these securities are converted and we are relieved of our debt obligation. This method does not take into account any increase or decrease in our cost of capital in an assumed conversion.

The year ended December 31, 2022 includes BPEA Transaction gain of $641.9 million and realized and unrealized gains on EQT ordinary shares of $43.8 million and $57.9 million, respectively, net of $167.6 million of income tax expense. The year ended December 31, 2023 includes Veritable Transaction gain of $133.1 million and realized gains on EQT shares of $29.6 million, net of $40.6 million income tax expense. Other economic items include gains and losses related to contingent payment obligations, tax windfalls and shortfalls from share-based compensation, certain Affiliate equity activity, unrealized gains and losses on seed capital, general partner commitments, and other strategic investments, and realized economic gains and losses related to these seed capital, general partner commitments, and other strategic investments. For the years ended December 31, 2021, 2022, and 2023, other economic items were net of income tax expense (benefit) of $21.8 million, $(6.4) million, and $5.2 million, respectively. Liquidity and Capital Resources We generate long-term value by investing in new Affiliate partnerships, existing Affiliates, and strategic value-add capabilities through which we can leverage our scale and resources to benefit our Affiliates and enhance their long-term growth prospects. Given our annual cash generation from operations, in addition to investing for growth in our business, we are also able to return excess capital to shareholders primarily through share repurchases. We continue to manage our capital structure consistent with an investment grade company and are currently rated A3 by Moody’s Investors Service and BBB+ by S&P Global Ratings. Cash and cash equivalents were $813.6 million as of December 31, 2023 and were attributable to both our controlling and the non-controlling interests. Our principal uses of cash in 2023 were for investments in new Affiliates, purchases of investment securities, distributions to Affiliate equity holders, and the return of excess capital through share repurchases. In 2023, we met our cash requirements primarily through cash generated by operating activities, proceeds from the Veritable Transaction, and proceeds from the sale of our remaining ordinary shares of EQT. We expect investments in new Affiliates, investments in existing Affiliates, primarily through purchases of Affiliate equity interests and general partner and seed capital investments, the return of capital through share repurchases and the payment of cash dividends on our common stock, repayment of debt, distributions to Affiliate equity holders, payment of income taxes, purchases of marketable securities, and general working capital to be the primary uses of cash on a consolidated basis for the foreseeable future. We anticipate that our current cash balance, cash flows from operations, proceeds from sales of our marketable securities, and borrowings under our senior unsecured multicurrency revolving credit facility (the “revolver”) will be sufficient to support our uses of cash for the foreseeable future. In addition, we may draw funding from the debt and equity capital markets, and our credit ratings, among other factors, allow us to access these sources of funding on favorable terms. The following table presents operating, investing, and financing cash flow activities: (in millions) Operating cash flow Investing cash flow Financing cash flow Operating Cash Flow For the Years Ended December 31, $ 2021 1,259.2 $ (583.7) (798.3) 2022 1,054.7 $ (109.9) (1,402.9) 2023 874.3 264.5 (758.3) Operating cash flows are calculated by adjusting Net income for other significant sources and uses of cash, significant non-cash items, and timing differences in the cash settlement of assets and liabilities. For the year ended December 31, 2023, Cash flows from operating activities were $874.3 million, primarily from Net income of $906.1 million adjusted for $490.8 million of distributions of earnings received from equity method investments and non-cash items of $303.3 million. These items were partially offset by timing differences in the cash settlement of receivables, other assets, and payables, accrued liabilities, and other liabilities of $228.6 million. In 2023, operating cash flows were primarily attributable to the controlling interest. Investing Cash Flow 32 Table of Contents For the year ended December 31, 2023, Cash flows from investing activities were $264.5 million, primarily due to $294.0 million of cash proceeds from the Veritable Transaction and $277.4 million of net maturities and sales of investment securities. These items were partially offset by $294.7 million of investments in Affiliates. In 2023, investing cash flows were primarily attributable to the controlling interest. Financing Cash Flow For the year ended December 31, 2023, Cash flows used in financing activities were $758.3 million, primarily due to $341.9 million of repurchases of common stock (net), $271.3 million of distributions to non-controlling interests, $55.3 million of other financing items, and $54.0 million of Affiliate equity purchases, net of issuances. Affiliate Equity We periodically purchase Affiliate equity from and issue Affiliate equity to our consolidated Affiliate partners and other parties, under agreements that provide us with a conditional right to call and Affiliate equity holders with a conditional right to put their Affiliate equity interests to us at certain intervals. We have the right to settle a portion of these purchases in shares of our common stock. For Affiliates accounted for under the equity method, we do not typically have such put and call arrangements. The purchase price of these conditional purchases is generally calculated based upon a multiple of the Affiliate’s cash flow distributions, which is intended to represent fair value. Affiliate equity holders are also permitted to sell their equity interests to other individuals or entities in certain cases, subject to our approval or other restrictions. As of December 31, 2023, the current redemption value of Affiliate equity interests was $447.3 million, of which $393.4 million was presented as Redeemable non-controlling interests (including $11.8 million of consolidated Affiliate sponsored investment products primarily attributable to third-party investors), and $53.9 million was included in Other liabilities. Although the timing and amounts of these purchases are difficult to predict, we paid $67.4 million for Affiliate equity purchases and received $13.4 million for Affiliate equity issuances in 2023, and we expect net purchases of approximately $100 million of Affiliate equity in 2024. In the event of a purchase, we become the owner of the cash flow associated with the purchased equity. See Notes 16 and 17 of our Consolidated Financial Statements. Share Repurchases Our Board of Directors authorized share repurchase programs in January 2022, October 2022, and October 2023 to repurchase up to 2.0 million, 3.0 million, and 3.3 million shares of our common stock, respectively, and these authorizations have no expiry. Purchases may be made from time to time, at management’s discretion, in the open market or in privately negotiated transactions, including through the use of trading plans, as well as pursuant to accelerated share repurchase programs or other share repurchase strategies that may include derivative financial instruments. For the year ended December 31, 2023, we repurchased 3.0 million shares of our common stock at an average price per share of $132.99. As of December 31, 2023, we had repurchased all of the shares in the repurchase program authorized in January 2022, and there were a total of 4.2 million shares available for repurchase under our share repurchase programs. In December 2022, we entered into an accelerated share repurchase agreement to repurchase shares of our common stock in exchange for an upfront payment of $225.0 million. We received an initial share delivery of 1.1 million shares in December 2022, which represents 80% of the upfront payment based on the closing price of our common stock on the agreement date. In June 2023, we received a final share delivery of 0.4 million shares. Under this agreement we repurchased a total of 1.5 million shares at an average price of $147.29 per share. In August 2022, the Inflation Reduction Act was enacted into law and included a provision for a 1% excise tax on repurchases of our common stock. This provision, which was effective for the Company beginning January 1, 2023, did not have a material impact on our Consolidated Financial Statements for the year ended December 31, 2023. We do not currently expect the excise tax to have a material impact on our financial position or cash flows. We record the excise tax as part of the cost basis of our common stock repurchased. Debt The following table presents the carrying value of our outstanding indebtedness. See Note 6 of our Consolidated Financial Statements. 33 Table of Contents (in millions) Senior bank debt Senior notes Junior subordinated notes Junior convertible securities December 31, 2021 2022 2023 $ 350.0 $ 350.0 $ 1,098.0 765.8 299.5 1,098.7 765.9 341.7 350.0 1,099.4 765.9 341.7 The carrying value of our debt differs from the amount reported in the notes to our Consolidated Financial Statements, as the carrying value of our debt in the table above is not reduced for debt issuance costs. Senior Bank Debt We have a $1.25 billion revolver and a $350.0 million term loan (together, the “credit facilities”). The revolver matures on October 25, 2027 and the term loan matures on October 23, 2026. Subject to certain conditions, we may increase the commitments under the revolver by up to an additional $500.0 million and may borrow up to an additional $75.0 million under the term loan. Under the terms of the credit facilities we are required to meet two financial ratio covenants. The first of these covenants is a maximum ratio of debt to EBITDA (the “bank leverage ratio”) of 3.25x. The second covenant is a minimum EBITDA to cash interest expense ratio of 3.00x (the “bank interest coverage ratio”). For purposes of calculating these ratios, share-based compensation and certain Affiliate equity expenses are added back to Adjusted EBITDA. As of December 31, 2023, our bank leverage and bank interest coverage ratios were 1.3x and 8.3x, respectively, and we were in compliance with all of the terms of our credit facilities. As of December 31, 2023, we had no outstanding borrowings under the revolver and could borrow all capacity and remain in compliance with our credit facilities. Senior Notes As of December 31, 2023, we had senior notes outstanding, the respective principal terms of which are presented below: Issue date Maturity date Par value (in millions) Stated coupon Coupon frequency Potential call date $ 2024 Senior Notes 2025 Senior Notes 2030 Senior Notes February 2014 February 2024 400.0 4.25 % Semi-annually Any time $ February 2015 August 2025 350.0 3.50 % Semi-annually Any time $ June 2020 June 2030 350.0 3.30 % Semi-annually Any time On February 15, 2024, our $400.0 million 4.25% senior notes due 2024 matured and were fully repaid.

The junior convertible securities were issued by AMG Capital Trust II, a Delaware statutory trust, in October 2007. Each of the junior convertible securities represents an undivided beneficial interest in the assets of the trust. The trust’s only assets are junior subordinated convertible debentures issued to it by us, and have substantially the same payment terms as the junior convertible securities. We own all of the trust’s common securities, and have fully and unconditionally guaranteed, on a subordinated basis, the payment obligations on the junior convertible securities. We do not consolidate the trust’s financial results into our Consolidated Financial Statements. Holders of the junior convertible securities have no rights to put these securities to us. Upon conversion, holders will receive cash or shares of our common stock, or a combination thereof, at our election. We may redeem the junior convertible securities, subject to our stock trading at or above certain specified levels over specified times periods, and may also repurchase junior convertible securities in the open market or in privately negotiated transactions from time to time at management’s discretion. The junior convertible securities are considered contingent payment debt instruments under federal income tax regulations, which require us to deduct interest in an amount greater than our reported interest expense. We estimate that these deductions will generate annual deferred tax liabilities of approximately $9 million. For the year ended December 31, 2022, we repurchased a portion of our junior convertible securities for a purchase price of $60.9 million and as a result of these repurchases, we reduced our Deferred income tax liability (net) by $11.4 million. We did not repurchase any of our junior convertible securities during the year ended December 31, 2023. Equity Distribution Program In the second quarter of 2022, we entered into equity distribution and forward equity agreements with several major securities firms under which we may, from time to time, issue and sell shares of our common stock (immediately or on a forward basis) having an aggregate sales price of up to $500.0 million (the “equity distribution program”). This equity distribution program superseded and replaced our prior equity distribution program. As of December 31, 2023, no sales had occurred under the equity distribution program. Commitments See Note 7 of our Consolidated Financial Statements. Other Contingent Commitments See Notes 4 and 7 of our Consolidated Financial Statements. Leases As of December 31, 2023, our lease obligations were $40.0 million through 2024, $61.5 million from 2025 through 2026, $43.9 million from 2027 through 2028, and $68.3 million thereafter. The portion of these lease obligations attributable to the controlling interest were $11.3 million through 2024, $13.6 million from 2025 through 2026, $3.9 million from 2027 through 2028, and $8.0 million thereafter. See Note 10 of our Consolidated Financial Statements. Recent Accounting Developments See Note 1 of our Consolidated Financial Statements. 35 Table of Contents Critical Accounting Estimates and Judgments The preparation of financial statements and related disclosures in conformity with GAAP requires us to make judgments, assumptions, and estimates that affect the amounts reported in our Consolidated Financial Statements and accompanying notes. See Note 1 of our Consolidated Financial Statements for a discussion of our significant accounting policies. The following are our critical accounting estimates and judgments used in the preparation of our Consolidated Financial Statements, and due to their subjectivity, actual results could differ materially from the amounts reported. Fair Value Measurements Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants at the measurement date. These standards establish a fair value hierarchy that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. We make judgments to determine the fair value of certain assets, liabilities, and equity interests when allocating the purchase price of our new investments, when revaluing our contingent payment obligations, when we issue or purchase Affiliate equity interests and when we test our goodwill, indefinite- and definite-lived acquired client relationships, or equity method investments for impairment. In determining fair values that reflect our own assumptions concerning unobservable inputs, we typically use valuation techniques, including probability-weighted discounted cash flow analyses and Monte Carlo simulations, where we make assumptions about growth rates of assets under management, client attrition, asset- and performance-based fee rates, and expenses. In these analyses, we also consider historical and current market multiples, tax benefits, credit risk, interest rates, tax rates, discount rates, volatility, and discounts for lack of marketability. We consider the reasonableness of our assumptions by comparing our valuation conclusions to observed market transactions and, in certain instances, by consulting with third-party valuation firms. Changes in the assumptions used could significantly impact fair values. Goodwill Goodwill represents the future economic benefits arising from assets acquired in a business combination that are not separately recognized. We perform a qualitative impairment assessment at least annually to determine if the carrying value of our single reporting unit is in excess of its fair value. In this qualitative assessment, we typically measure the excess of the fair value of our reporting unit over its carrying value using various qualitative and quantitative factors (including our market capitalization). If there is an indication that the carrying value of the reporting unit is in excess of the fair value under this test, then we must determine if a potential impairment is more-likely-than-not. To determine if a potential impairment is more-likely-than-not, we perform a single step quantitative test with any excess of carrying value over fair value recorded as an expense in Intangible amortization and impairments. We completed our annual qualitative goodwill impairment assessment as of September 30, 2023 and no impairment was indicated. Based on our assessment, the fair value of our reporting unit was substantially greater than its respective carrying amount, including goodwill. Indefinite-Lived Acquired Client Relationships Indefinite-lived acquired client relationships include investment advisory contracts between our Affiliates and their mutual funds and other retail- oriented investment products. Because these contracts are with the investment products themselves, and not with the underlying investors, and the contracts between our Affiliates and the investment products are typically renewed on an annual basis, industry practice under GAAP is to consider the contract life to be indefinite and, as a result, not amortizable. We perform indefinite-lived acquired client relationship impairment assessments annually, or more frequently should circumstances indicate fair value has declined below the related carrying value. For purposes of our assessments, we consider various qualitative and quantitative factors to determine if it is more-likely-than-not that the fair value of each asset group is greater than its carrying amount. If we determine that it is likely that the fair value has declined below our related carrying value, we perform discounted cash flow analyses to determine the fair value of the asset group and record an expense in Intangible amortization and impairments to reduce the carrying value to its fair value. For the year ended December 31, 2023, we completed our annual assessment and only a significant decline in the fair values of these assets would result in an impairment. 36 Table of Contents Equity Method Investments in Affiliates We periodically perform assessments to determine if the fair value of an investment may have declined below its related carrying value for our Affiliates accounted for under the equity method for a period that we consider to be other-than-temporary. We perform these assessments if certain triggering events occur or annually during the fourth quarter. We first consider whether certain qualitative and quantitative factors (including discount rates) indicate an increased likelihood of a decline in the fair value of an Affiliate during the reporting period. If such a decline is identified, and it is likely that an investment’s fair value may have declined below its carrying value, we perform a quantitative assessment to determine if an impairment exists. Impairments are recorded as an expense in Equity method income (net) to reduce the carrying value of the Affiliate to its fair value. When we quantitatively test our equity method investments for impairment, we typically use valuation methods such as discounted cash flow analyses. In these analyses, our most significant assumptions relate to growth rates of projected assets under management, client attrition, asset- and performance- based fees, expenses, and discount rates. We consider the reasonableness of our assumptions by comparing our valuation conclusions to observed market transactions, comparable company valuations, and, in certain instances, by consulting with third-party valuation firms. Changes in these assumptions could significantly impact the respective fair value of an Affiliate. Item 7A. Quantitative and Qualitative Disclosures About Market Risk Assets Under Management Market Price Risk Our Consolidated revenue and equity method revenue are derived primarily from asset-based fees that are typically determined as a percentage of the value of a client’s assets under management. Such values are affected by changes in financial markets (including declines in the capital markets, fluctuations in foreign currency exchange rates, inflation rates or the yield curve, and other market factors) and, accordingly, declines in the financial markets may negatively impact our Consolidated revenue and equity method revenue. As of December 31, 2023, we estimate a proportional 1% change in the value of our assets under management would have resulted in a $16.3 million annualized change in asset-based fees in Consolidated revenue for our consolidated Affiliates and a $14.8 million annualized change in asset-based fees in equity method revenue for our Affiliates accounted for under the equity method. This proportional increase or decrease excludes assets under management on which asset-based fees are charged on committed capital. Interest Rate Risk We have fixed rates of interest on our senior notes, junior subordinated notes, and junior convertible securities. While a change in market interest rates would not affect the interest expense incurred on our fixed rate securities, such a change may affect the fair value of these securities. We estimate that a 1% change in interest rates would have resulted in a $145.7 million net change in the fair value of our fixed rate securities as of December 31, 2023. We pay a variable rate of interest on our credit facilities at specified rates, based either on an applicable term Secured Overnight Financing Rate (“SOFR”) plus a SOFR adjustment of 0.10% or prime rate, plus a marginal rate determined based on our credit rating. As of December 31, 2023, the interest rate for our outstanding borrowings under the term loan was term-SOFR plus a SOFR adjustment of 0.10%, plus the marginal rate of 0.85%. We estimate that a 1% change in interest rates would have changed our annual interest expense on the outstanding balances under our credit facilities by $3.5 million, as of December 31, 2023. Foreign Currency Risk The functional currency of most of our Affiliates is the U.S. dollar. Certain of our Affiliates have the pound sterling, Canadian dollar, or the Euro as their functional currency, and are, therefore, impacted by movements in pound sterling, Canadian dollar, and Euro to U.S. dollar foreign currency exchange rates. In addition, the valuations of our foreign Affiliates with a non-U.S. dollar functional currency change based on fluctuations in foreign currency exchange rates, among other factors. Changes due to fluctuations in foreign currency exchange rates are recorded as a component of stockholders’ equity. To illustrate the effect of possible changes in foreign currency exchange rates, we estimate a 1% change in the pound sterling, Canadian dollar, and Euro to U.S. dollar exchange rates would have resulted in a $8.0 million, $2.1 million, and $1.2 million change to stockholders’ equity, respectively, based on the December 31, 2023 carrying value of Affiliates whose functional currency is the pound sterling, Canadian dollar, or the Euro, and of our and our Affiliates’ pound sterling- and Euro-denominated derivative financial instruments. For the year ended December 31, 2023, we estimate a 1% change in the pound 37 Table of Contents sterling, Canadian dollar, and the Euro to U.S. dollar exchange rates would have resulted in $1.2 million, $0.3 million, and $0.0 million in annual changes to Income before income taxes (controlling interest), respectively. Derivative Risk From time to time, we and our Affiliates seek to offset exposure to changes in interest rates, foreign currency exchange rates, and markets by entering into derivative financial instruments. There can be no assurance that our or our Affiliates’ derivative financial instruments will meet their overall objective or that we or our Affiliates will be successful in entering into such instruments in the future. 38 Table of Contents Item 8. Financial Statements and Supplementary Data Management’s Report on Internal Control Over Financial Reporting Management of Affiliated Managers Group, Inc. (the “Company”) is responsible for establishing and maintaining adequate internal control over financial reporting. The Company’s internal control over financial reporting processes are designed by, or under the supervision of, the Company’s chief executive and chief financial officers and applied by the Company’s Board of Directors, management, and other senior employees to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company’s financial statements for external reporting purposes in accordance with accounting principles generally accepted in the U.S. The Company’s internal control over financial reporting includes policies and procedures that pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of assets; provide reasonable assurances that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the U.S., and that receipts and expenditures are being made only in accordance with authorizations of management and the directors of the Company; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on its financial statements. As of December 31, 2023, management conducted an assessment of the effectiveness of the Company’s internal control over financial reporting based on the framework established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, management has determined that the Company’s internal control over financial reporting as of December 31, 2023 was effective. The Company’s internal control over financial reporting as of December 31, 2023 has been audited by PricewaterhouseCoopers LLP (PCAOB ID 238), an independent registered public accounting firm, as stated in their report appearing in “Report of Independent Registered Public Accounting Firm,” which expresses an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2023. 39 Table of Contents To the Board of Directors and Stockholders of Affiliated Managers Group, Inc. Opinions on the Financial Statements and Internal Control over Financial Reporting Report of Independent Registered Public Accounting Firm We have audited the accompanying consolidated balance sheets of Affiliated Managers Group, Inc. and its affiliates (the “Company”) as of December 31, 2023 and 2022, and the related consolidated statements of income, of comprehensive income, of changes in equity and of cash flows for each of the three years in the period ended December 31, 2023, including the related notes and financial statement schedule listed in the index appearing under Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO. Basis for Opinions The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 8. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. 40 Table of Contents Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Critical Audit Matters The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Impairment Assessment for Certain Equity Method Investments in Affiliates As described in Notes 1 and 9 to the consolidated financial statements, the Company’s equity method investments in affiliates balance was $2,288.5 million as of December 31, 2023, a portion of which related to certain equity method investments. For its affiliates accounted for under the equity method, management periodically performs assessments to determine if the fair value of an investment may have declined below its related carrying value for a period that management considers to be other-than-temporary. Management first considers whether certain qualitative and quantitative factors (including discount rates) indicate an increased likelihood of a decline in the fair value. If such a decline is identified, and it is likely that an investment’s fair value may have declined below its carrying value, management performs a quantitative assessment to determine if an impairment exists. The principal considerations for our determination that performing procedures relating to the impairment assessment for certain equity method investments in affiliates is a critical audit matter are (i) the significant judgment by management in assessing whether there were certain qualitative and quantitative factors indicating an increased likelihood of a decline in the fair value of certain equity method investments in affiliates, (ii) a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating audit evidence related to management’s assessment of indicators of impairment related to the discount rate assumptions, and (iii) the audit effort involved the use of professionals with specialized skill and knowledge. Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management’s impairment assessment for equity method investments in affiliates to assess whether there were certain qualitative and quantitative factors indicating an increased likelihood of a decline in the fair value. These procedures also included, among others, (i) testing management’s process for assessing whether there were certain qualitative and quantitative factors indicating an increased likelihood of a decline in the fair value of certain equity method investments in affiliates, (ii) testing the completeness and accuracy of the underlying data used in management’s assessment of indicators of an increased likelihood of a decline in the fair value, (iii) evaluating the reasonableness of management’s discount rate assumptions by considering whether the assumptions were consistent with evidence obtained in other areas of the audit, (iv) and the involvement of professionals with specialized skill and knowledge to assist in evaluating the reasonableness of management’s discount rate assumptions. /s/ PricewaterhouseCoopers LLP Boston, Massachusetts February 16, 2024 We have served as the Company’s auditor since 1993. 41 Table of Contents Consolidated revenue Consolidated expenses: Compensation and related expenses Selling, general and administrative Intangible amortization and impairments Interest expense Depreciation and other amortization Other expenses (net) Total consolidated expenses Equity method income (net) Affiliate Transaction gains (Notes 8 and 9) Investment and other income Income before income taxes Income tax expense Net income Net income (non-controlling interests) Net income (controlling interest) Average shares outstanding (basic) Average shares outstanding (diluted) Earnings per share (basic) Earnings per share (diluted) AFFILIATED MANAGERS GROUP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. Business and Summary of Significant Accounting Policies (a) Organization and Nature of Operations Affiliated Managers Group, Inc. (“AMG” or the “Company”) is a strategic partner to leading independent investment management firms globally. AMG’s strategy is to generate long-term value by investing in a diverse array of high-quality independent partner-owned firms, referred to as “Affiliates.” The Company’s Affiliates provide a comprehensive and diverse range of differentiated investment strategies designed to assist institutional and wealth clients worldwide in achieving their investment objectives. The Company operates in one segment, global investment management. Each of the Company’s Affiliates operates through distinct legal entities, which affords the Company the flexibility to design a separate operating agreement for each Affiliate. Each operating agreement reflects the specific terms of the Company’s economic participation in the Affiliate, which, in each case, uses a “structured partnership interest.” The form of the Company’s structured partnership interests in Affiliates differs from Affiliate to Affiliate and ranges from structures where the Company contractually shares in the Affiliate’s revenue without regard to expenses, comprising Affiliates that contribute a majority of the Company’s Consolidated revenue, to others where the Company contractually shares in the Affiliate’s revenue less agreed-upon expenses. Further, the structure at a particular Affiliate, or the expenses that the Company agrees to share in, may change during the course of the Company’s investment. Where the Company shares in the Affiliate’s revenue without regard to expenses, the Affiliate allocates a specified percentage of its revenue to the Company and Affiliate management, while using the remainder for operating expenses and additional distributions to Affiliate management. The Company and Affiliate management, therefore, participate in any increase or decrease in revenue and only Affiliate management participates in any increase or decrease in expenses. Under these structured partnership interests, the Company’s contractual share of revenue generally has priority over distributions to Affiliate management. Where the Company shares in the Affiliate’s revenue less agreed-upon expenses, the Company benefits from any increase in revenue or any decrease in the agreed-upon expenses, but also has exposure to any decrease in revenue or any increase in such agreed-upon expenses. The degree of the Company’s exposure to agreed-upon expenses from these structured partnership interests varies by Affiliate, and includes several Affiliates in which the Company fully shares in the expenses of the business. (b) Basis of Presentation and Use of Estimates The Consolidated Financial Statements of the Company have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”). All dollar amounts, except per share data in the text and tables herein, are stated in millions unless otherwise indicated. All intercompany balances and transactions have been eliminated. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from those estimates. (c) Principles of Consolidation In evaluating whether an investment must be consolidated, the Company evaluates the risk, rewards, and significant terms of each of its Affiliates and other investments to determine if an investment is considered a voting rights entity (“VRE”) or a variable interest entity (“VIE”). An entity is a VRE when the total equity investment at risk is sufficient to enable the entity to finance its activities independently, and when the equity holders have the obligation to absorb losses, the right to receive residual returns, and the right to direct the activities of the entity that most significantly impact its economic performance. An entity is a VIE when it lacks one or more of the characteristics of a VRE, which, for the Company, are Affiliate investments structured as partnerships (or similar entities) where the Company is a limited partner and lacks substantive kick-out or substantive participation rights over the general partner. Assessing whether an entity is a VRE or VIE involves judgment. Upon the occurrence of certain events, management reviews and reconsiders its previous conclusion regarding the status of an entity as a VRE or a VIE. The Company consolidates VREs when it has control over significant operating, financial, and investing decisions of the entity. When the Company lacks such control, but is deemed to have significant influence, the Company accounts for the VRE under the equity method. Investments with readily determinable fair values in which the Company does not have rights to exercise significant influence are recorded at fair value on the Consolidated Balance Sheets, with changes in fair value included in Investment and other income on the Consolidated Statements of Income. 48 Table of Contents AFFILIATED MANAGERS GROUP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) The Company consolidates VIEs when it is the primary beneficiary of the entity, which is defined as having the power to direct the activities that most significantly impact the VIE’s economic performance and the obligation to absorb losses of, or the right to receive benefits from, the entity that could potentially be significant to the VIE. Substantially all of the Company’s consolidated Affiliates considered VIEs are controlled because the Company holds a majority of the voting interests or it is the managing member or general partner. Furthermore, an Affiliate’s assets can be used for purposes other than the settlement of the respective Affiliate’s obligations. The Company applies the equity method of accounting to VIEs where the Company is not the primary beneficiary, but has the ability to exercise significant influence over operating and financial matters of the VIE. See Note 5. Investments in Affiliates Substantially all of the Company’s Affiliates are considered VIEs and are either consolidated or accounted for under the equity method. A limited number of the Company’s Affiliates are considered VREs and most of these are accounted for under the equity method. When an Affiliate is consolidated, the portion of the earnings attributable to Affiliate management’s and any co-investor’s equity ownership is included in Net income (non-controlling interests) in the Consolidated Statements of Income. Undistributed earnings attributable to Affiliate management’s and any co-investor’s equity ownership, along with their share of any tangible or intangible net assets, are included in Non-controlling interests on the Consolidated Balance Sheets. Affiliate equity interests where the holder has certain rights to demand settlement are presented, at their current redemption values, as Redeemable non-controlling interests or Other liabilities on the Consolidated Balance Sheets. The Company periodically issues, sells, and purchases the equity of its consolidated Affiliates. Because these transactions take place between entities under common control, any gains or losses attributable to these transactions are required to be included in Additional paid-in capital on the Consolidated Balance Sheets, net of any related income tax effects in the period the transaction occurs. When an Affiliate is accounted for under the equity method, the Company’s share of an Affiliate’s earnings or losses, net of amortization and impairments, is included in Equity method income (net) in the Consolidated Statements of Income and the carrying value of the Affiliate is recorded in Equity method investments in Affiliates (net) in the Consolidated Balance Sheets. The Company periodically performs assessments to determine if the fair value of an investment may have declined below its related carrying value for its Affiliates accounted for under the equity method for a period that the Company considers to be other-than-temporary. The Company performs these assessments if certain triggering events occur or annually during the fourth quarter. The Company first considers whether certain qualitative factors indicate an increased likelihood of a decline in the fair value of an Affiliate during the reporting period. If such a decline is identified, and it is likely that an investment’s fair value may have declined below its carrying value, the Company performs a quantitative assessment to determine if an impairment exists. Impairments are recorded as an expense in Equity method income (net) to reduce the carrying value of the Affiliate to its fair value. Affiliate Sponsored Investment Products The Company’s Affiliates sponsor various investment products where the Affiliate also acts as the investment adviser. These investment products are typically owned primarily by third-party investors; however, certain products are funded with general partner and seed capital investments from the Company and its Affiliates. Third-party investors in Affiliate sponsored investment products are generally entitled to substantially all of the economics of these products, except for the asset- and performance-based fees earned by the Company’s Affiliates or any gains or losses attributable to the Company’s or its Affiliates’ investments in these products. As a result, the Company generally does not consolidate these products. However, for certain products, the Company’s consolidated Affiliates, as the investment manager, have the power to direct the activities of the investment product and have an exposure to the economics of the VIE that is more than insignificant, though generally only for a short period while the product is established and has yet to attract significant third- party investors. When the products are consolidated, the Company retains the specialized investment company accounting principles of the underlying products, and all of the underlying investments are carried at fair value in Investments in marketable securities on the Consolidated Balance Sheets, with corresponding changes in the investments’ fair values included in Investment and other income. Purchases and sales of securities are included in purchases and sales by consolidated Affiliate sponsored investment products in the Consolidated Statements of Cash Flows, respectively, and the third-party investors’ interests are recorded in Redeemable non-controlling interests. When the Company or its consolidated Affiliates no longer control these products, due to a reduction in ownership or other reasons, the products are deconsolidated with only the Company’s or its consolidated Affiliate’s investment in the product reported from the date of deconsolidation. 49 Table of Contents (d) Cash and Cash Equivalents AFFILIATED MANAGERS GROUP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) The Company considers certain highly liquid investments, including money market mutual funds, with original maturities of three months or less to be cash equivalents. Cash equivalents are stated at cost, which approximates market value due to the short-term maturity of these investments. Money market mutual funds with a floating net asset value (“NAV”) would not meet the definition of a cash equivalent if the fund has enacted liquidity fees or redemption gates. (e) Receivables The Company’s Affiliates earn asset- and performance-based fees, which are billed based on the terms of the related contracts. Billed but uncollected asset- and performance-based fees are recorded in Receivables on the Consolidated Balance Sheets and are generally short-term in nature. Certain of the Company’s Affiliates in the UK act as intermediaries between clients and their sponsored investment products. Normal settlement periods on transactions initiated by these clients with the sponsored investment products result in unsettled fund share receivables and payables that are presented on a gross basis within Receivables and Payables and accrued liabilities on the Consolidated Balance Sheets. The gross presentation of these receivables and offsetting payables reflects the legal relationship between the underlying investor, the Company’s Affiliates, and the sponsored investment products. (f) Investments in Marketable Securities Equity securities Realized and unrealized gains or losses on investments in equity securities are recorded in Investment and other income. Realized gains and losses are recorded on the trade date on a specific identified basis, except for consolidated Affiliate sponsored investment products which use an average cost basis. Debt securities Investments in debt securities are classified as either trading, available-for-sale, or held-to-maturity based on the Company’s intent and ability to hold the security to maturity. Securities classified as trading are measured at fair value with unrealized gains and losses recorded in Investment and other income. Securities classified as available-for-sale are measured at fair value with unrealized gains and losses recorded in Accumulated other comprehensive loss as a separate component of stockholders’ equity on the Consolidated Balance Sheets. Securities classified as held-to-maturity are measured at amortized cost. Realized gains and losses on debt securities are recorded in Investment and other income. (g) Fair Value Measurements The Company determines the fair value of certain investment securities and other financial and non-financial assets and liabilities. Fair value is determined based on the price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants in the principal or most advantageous market at the measurement date, utilizing a hierarchy of three different valuation techniques: Level 1 - Unadjusted quoted market prices for identical instruments in active markets; Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs, or significant value drivers, are observable; and Level 3 - Prices that reflect the Company’s own assumptions concerning unobservable inputs to the valuation model. In these valuation models, the Company is required to make judgments about growth rates of assets under management, client attrition, asset- and performance-based fee rates, and expenses. These valuation models also require judgments about tax benefits, credit risk, interest rates, tax rates, discount rates, volatility, and discounts for lack of marketability. These inputs require significant management judgment and reflect the Company’s assumptions that the Company believes market participants would use in pricing the asset or liability. (h) Acquired Client Relationships and Goodwill Each Affiliate in which the Company makes an investment has identifiable assets arising from contractual or other legal rights with their clients (“acquired client relationships”). In determining the value of acquired client relationships, the Company analyzes the net present value of these Affiliates’ existing client relationships based on a number of factors, including: the Affiliate’s historical and potential future operating performance; the Affiliate’s historical and potential future rates of attrition 50 Table of Contents AFFILIATED MANAGERS GROUP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) of existing clients; the stability and longevity of existing client relationships; the Affiliate’s recent, as well as long-term, investment performance; the characteristics of the firm’s products and investment styles; the stability and depth of the Affiliate’s management team; and the Affiliate’s history and perceived franchise or brand value. The Company has determined that certain of its acquired client relationships meet the criteria to be considered indefinite-lived assets because the Company expects the contracts to be renewed annually and, therefore, the cash flows generated by these contracts to continue indefinitely. Accordingly, the Company does not amortize these intangible assets, but instead assesses these assets annually or more frequently whenever events or circumstances occur indicating that the recorded indefinite-lived acquired client relationship may be impaired. Each reporting period, the Company assesses whether events or circumstances have occurred that indicate that the indefinite life criteria are no longer met. The Company has determined that certain of its acquired client relationships meet the criteria to be considered definite-lived assets, including investment advisory contracts between its Affiliates and their underlying investors, and are amortized over their expected period of economic benefit. The expected period of economic benefit of definite-lived acquired client relationships is a judgment based on the historical and projected attrition rates of each Affiliate’s existing clients, and other factors that may influence the expected future economic benefit the Company will derive from these relationships. The expected lives of definite-lived acquired client relationships are analyzed annually or more frequently whenever events or circumstances have occurred that indicate the expected period of economic benefit may no longer be appropriate. The Company assesses for the possible impairment of indefinite- and definite-lived acquired client relationships annually or more frequently whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. If such indicators exist, the Company considers various qualitative and quantitative factors (including market multiples) to determine if the fair value of each asset is greater than its carrying value. If the carrying value is greater than the fair value, an expense would be recorded in Intangible amortization and impairments in the Consolidated Statements of Income to reduce the carrying value of the asset to fair value. Goodwill represents the future economic benefits arising from assets acquired in a business combination that are not separately recognized. Goodwill is not amortized, but is instead reviewed for impairment. The Company performs an impairment assessment annually or more frequently whenever events or circumstances occur indicating that the carrying value of its single reporting unit is in excess of its fair value. In this assessment, the Company typically measures the fair value of its reporting unit using various qualitative and quantitative factors (including the Company’s market capitalization and market multiples for asset management businesses). If a potential impairment is more-likely-than-not, then the Company will perform a single step assessment with any excess of carrying value over fair value recorded as an expense in Intangible amortization and impairments. (i) Fixed Assets Fixed assets are recorded at cost and depreciated using the straight-line method over their estimated useful lives. The estimated useful lives of office equipment and furniture and fixtures range from two years to ten years and three years to ten years, respectively. Computer software developed or obtained for internal use is amortized over the estimated useful life of the software, generally two years to five years. Leasehold improvements are amortized over the shorter of their estimated useful lives or the term of the lease. Buildings are amortized over their expected useful lives, generally not to exceed 39 years. The costs of improvements that extend the life of a fixed asset are capitalized, while the cost of repairs and maintenance are expensed as incurred. Land and artwork are not depreciated; artwork is included in Other assets on the Consolidated Balance Sheets. (j) Leases Leases are classified as either operating leases or finance leases. The Company and its Affiliates currently lease office space and equipment primarily under operating lease arrangements. As these leases expire, it is expected that, in the normal course of business, they will be renewed or replaced. Whether a lease is classified as an operating lease or a finance lease, the Company and its Affiliates must record a right-of-use asset and a lease liability at the commencement date of the lease, other than for leases with an initial term of 12 months or less. As permitted under Accounting Standard Update (“ASU”) 2016-02 Leases (and related ASUs), the Company and its Affiliates elect not to record short-term leases with an initial lease term less than 12 months on the Consolidated Balance Sheets. Right-of-use assets and lease liabilities are included in Other assets and Other liabilities, respectively. A lease liability is initially and subsequently reported at the present value of the outstanding lease payments determined by discounting those lease payments over the remaining lease term using the incremental borrowing rate of the legal entity entering into the lease as of the commencement date. A right-of-use asset is initially reported at the present value of the corresponding lease liability plus any prepaid lease payments and initial direct costs of entering into the 51 Table of Contents AFFILIATED MANAGERS GROUP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) lease, and reduced by any lease incentives. Subsequently, a right-of-use asset is reported at the present value of the lease liability adjusted for any prepaid or accrued lease payments, remaining balances of any lease incentives received, unamortized initial direct costs of entering into the lease, and any impairments of the right-of-use asset. The Company and its Affiliates test for possible impairments of right-of-use assets annually or more frequently whenever events or changes in circumstances indicate that the carrying value of a right-of-use asset may exceed its fair value. If the carrying value of the right-of-use asset exceeds its fair value, then the carrying value of the right-of-use asset is reduced to its fair value and the expense is recorded in Other expenses (net) in the Consolidated Statements of Income. Subsequent to an impairment, the carrying value of the right-of-use asset is amortized on a straight-line basis over the remaining lease term. Lease liabilities and right-of-use assets based on variable lease payments that depend on an index or rate are initially measured using the index or rate at the commencement date with any subsequent changes in variable lease payments recorded in Other expenses (net) as incurred. Most lease agreements for office space that are classified as operating leases contain renewal options, rent escalation clauses, or other lease incentives provided by the lessor. Lease expense is accrued to recognize lease escalation provisions and renewal options that are reasonably certain to be exercised, as well as lease incentives provided by the lessor, on a straight-line basis over the lease term and is recorded in Other expenses (net). If a right-of-use asset is impaired, the lease expense is subsequently recorded in Other expenses (net) as the straight-line amortization of the right-of-use asset and the accretion of the lease liability, thereby transitioning to a front-loaded expense recognition profile for the associated lease. The Company and its Affiliates combine lease and non-lease components for their office space leases and separate non-lease components for their equipment leases in calculating their lease liabilities. Sublease income is recorded in Investment and other income. (k) Debt The Company’s debt instruments are carried at amortized cost. Unamortized discounts and debt issuance costs associated with its debt instruments, with the exception of the Company’s senior unsecured multicurrency revolving credit facility (the “revolver”), are presented on the Consolidated Balance Sheets as an adjustment to the carrying value of the associated debt. The carrying value of the debt is accreted to the principal amount at maturity over the remaining life of the underlying debt. The accretion of the debt and the amortization of debt issuance costs, are recorded in Interest expense in the Consolidated Statements of Income, using the effective interest method. Unamortized issuance costs associated with the revolver are recorded in Other assets and amortized over the remaining term of the revolver to Interest expense. Gains and losses on repurchases or settlement of debt are recorded in Interest expense. (l) Derivative Financial Instruments The Company and its Affiliates may use derivative financial instruments to offset exposure to changes in interest rates, foreign currency exchange rates, and markets. The Company records derivatives on the Consolidated Balance Sheets at fair value. The Company assesses hedge effectiveness at derivative inception and on a quarterly basis. Changes in fair value of a hedging instrument that are excluded from the assessment of hedge effectiveness, also known as excluded components, are recorded in earnings on a straight-line basis over the respective period of the contracts. For derivative financial instruments designated as cash flow hedges, the Company uses a qualitative method of assessing hedge effectiveness by comparing the notional amounts, timing of payments, currencies (for forward foreign currency contracts), and interest rates (for interest rate swaps). The effective portion of the unrealized gain or loss is recorded in Other comprehensive income (loss), net of tax as a separate component of stockholders’ equity and reclassified to earnings with the hedged item. If the qualitative assessment indicates ineffectiveness, then the Company performs a quantitative assessment which is generally measured by comparing the present value of the cumulative change in the expected future cash flows of the hedged contract with the present value of the cumulative change in the expected future cash flows of the hedged item. Upon termination of these instruments or the repayment of the Company’s outstanding Secured Overnight Financing Rate (“SOFR”)-based borrowings, any gain or loss recorded in Accumulated other comprehensive loss will be reclassified into earnings. Changes in the fair values of cash flow hedges are recorded in Change in net realized and unrealized gain (loss) on derivative financial instruments in the Consolidated Statements of Comprehensive Income. For net investment hedges, hedge effectiveness is measured using the spot rate method. The effective portion of the unrealized gain or loss is recorded in Other comprehensive income (loss) as a separate component of stockholders’ equity and 52 Table of Contents AFFILIATED MANAGERS GROUP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) reclassified to earnings with the hedged item. Changes in the fair values of the effective net investment hedges are recorded in Foreign currency translation gain (loss) in the Consolidated Statements of Comprehensive Income. Upon the sale or liquidation of the underlying investment, any gain or loss remaining in Accumulated other comprehensive loss will be reclassified to earnings. If the Company’s or its Affiliates’ derivative financial instruments do not qualify as effective hedges, changes in the fair value of the derivatives are recorded as a gain or loss in Investment and other income. (m) Revenue Recognition Consolidated revenue primarily represents asset- and performance-based fees earned by the Company and its consolidated Affiliates for managing the assets of clients. Substantially all of the Company’s and its Affiliates’ contracts contain a single performance obligation, which is the provision of investment management services. Investment management, broker-dealer, and administrative services are performed and consumed simultaneously and, therefore, the Company recognizes these asset-based fees ratably over time. Substantially all the Company’s asset-based fees for services are based on the value of client assets over time, which are typically determined using observable market data, or on committed capital. Services may be invoiced in advance or in arrears and are payable upon receipt. Any asset-based fees collected in advance are deferred and recognized as the services are performed and consumed. Consolidated revenue recognized by the Company is adjusted for any expense reimbursement arrangements. The Company’s Affiliates may periodically either waive or reduce fees in order to attract or retain client assets or for other reasons. Fee waivers or reductions are presented as a reduction to Consolidated revenue in the Consolidated Statements of Income. Performance-based fees, including carried interests, are recognized upon the satisfaction of performance obligations, the resolution of any constraints, which include exceeding performance benchmarks or hurdle rates that may extend over one or more reporting periods, and when it is improbable that there will be a significant reversal in the amount of revenue recognized. As a result, any performance-based fees or carried interest recognized in the current reporting period may relate to performance obligations satisfied in a previous reporting period. The Company and its Affiliates have contractual arrangements with third-parties to provide distribution-related services. Fees received and expenses incurred under these arrangements are primarily based on the value of client assets over time. Distribution-related fees are recorded in Consolidated revenue gross of any related expenses when the Company and its consolidated Affiliates are the principal in their role as primary obligor under their distribution-related services arrangements. Distribution-related expenses are recorded in Selling, general and administrative expenses in the Consolidated Statements of Income. The Company and its Affiliates may enter into contracts for which the costs to obtain or fulfill the contract are based upon a percentage of the value of a client’s future assets under management. The Company records these variable costs when incurred because they are subject to market volatility and are not estimable upon the inception of a contract with a client. Any expenses paid in advance are capitalized and amortized on a systematic basis, consistent with the transfer of services, which is the equivalent of recognizing the costs as incurred. (n) Contingent Payment Obligations The Company periodically enters into contingent payment obligations in connection with its investments in Affiliates. In these obligations, the Company agrees to pay additional consideration to the sellers to the extent that certain specified financial targets are achieved. For consolidated Affiliates, the Company estimates the fair value of these potential future obligations at the time the investment in an Affiliate is consummated and records a liability in Other liabilities. The Company then accretes the obligation to its expected payment amount over the period until the arrangement is measured. If the Company’s expected payment amount subsequently changes, the obligation is reduced or increased in the current period resulting in a gain or loss, respectively. Gains and losses resulting from changes to expected payments are included in Other expenses (net) and the accretion of these obligations to their expected payment amounts are included in Interest expense. For Affiliates accounted for under the equity method, the Company records a liability in Other liabilities when a payment becomes probable, with a corresponding increase to the carrying value of the Affiliate in Equity method investments in Affiliates (net). (o) Income Taxes The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of differences between the financial reporting bases of assets and liabilities and their respective tax bases, using tax rates in effect for the year in which the differences are expected to 53 Table of Contents AFFILIATED MANAGERS GROUP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recorded in Income tax expense in the period when the change is enacted. The Company regularly assesses the recoverability of its deferred income tax assets to determine whether these assets are more-likely-than-not to be realized. In making such a determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies, and results of recent operations. If the Company determines it would not be able to realize its deferred tax assets, it records a valuation allowance to reflect the deferred tax assets at their current value. The recording of adjustments to the valuation allowance will increase or decrease Income tax expense. The Company records unrecognized tax benefits based on whether it is more-likely-than-not that the uncertain tax positions will be sustained on the basis of the technical merits of the position. If it is determined that an uncertain tax position is more-likely-than-not to be sustained, the Company records the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority in Income tax expense. Interest and penalties related to unrecognized tax benefits are also recorded in Income tax expense. The Company has elected to treat taxes due on U.S. inclusions in taxable income related to Global Intangible Low Taxed Income (“GILTI”) as a current period expense when incurred (the “period cost method”). (p) Foreign Currency Translation Assets and liabilities denominated in a functional currency other than the U.S. dollar are translated into U.S. dollars using exchange rates in effect as of the balance sheet date. Revenue and expenses denominated in a functional currency other than the U.S. dollar are translated into U.S. dollars using average exchange rates for the relevant period. Because of the long-term nature of the Company’s investments in its Affiliates, net translation exchange gains and losses resulting from foreign currency translation are recorded in Accumulated other comprehensive loss. Foreign currency transaction gains and losses are included in Investment and other income. (q) Concentration of Credit Risk Financial instruments that potentially subject the Company to significant concentrations of credit risk consist principally of cash investments and derivative financial instruments. The Company and its Affiliates maintain cash and cash equivalents, investments, and, at times, certain derivative financial instruments with various high credit-quality financial institutions. These financial institutions are typically located in countries in which the Company and its Affiliates operate. For the Company and certain of its Affiliates, cash deposits at a financial institution may, from time to time, exceed insurance limits (similar to Federal Deposit Insurance Corporation insurance limits). (r) Earnings Per Share The calculation of Earnings per share (basic) is based on the weighted average number of shares of the Company’s common stock outstanding during the period. Earnings per share (diluted) is similar to Earnings per share (basic), but adjusts for the dilutive effect of the potential issuance of incremental shares of the Company’s common stock. The Company had share-based compensation awards outstanding during the periods presented with vesting provisions subject to certain performance conditions. These awards are excluded from the calculation of Earnings per share (diluted) if the performance condition has not been met as of the end of the reporting period. The Company has agreements with Affiliate equity holders that provide the Company a conditional right to call and holders a conditional right to put their interests to the Company at certain intervals. These arrangements are presented at their current redemption value as Redeemable non-controlling interests. The Company may settle these interests in cash or, subject to the terms of the applicable agreement, shares of its common stock, or other forms of consideration, at its option. Prior to 2022, the Company excluded any potential dilutive effect from possible share settlements of Redeemable non- controlling interests as the Company currently intends to settle in cash. Upon adoption of ASU 2020-06, the Company must assume the settlement of all of its Redeemable non-controlling interests using the maximum number of shares permitted under its arrangements. Purchases are assumed to occur at the beginning of the reporting period. The Company acquires the rights to the underlying Affiliate equity when purchased, and therefore, the earnings that would be acquired (net of tax) are assumed to increase Net income (controlling interest) in the computation of Earnings per share (diluted). The issuance of shares and the related income acquired are excluded from the calculation if an assumed purchase of Redeemable non-controlling interests would be anti- dilutive to diluted earnings per share. 54 Table of Contents AFFILIATED MANAGERS GROUP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) The Company had junior convertible securities outstanding during the periods presented and is required to apply the if-converted method to these securities in its calculation of Earnings per share (diluted). Under the if-converted method, shares that are issuable upon conversion are deemed outstanding, regardless of whether the securities are contractually convertible into the Company’s common stock at that time. For this calculation, the interest expense (net of tax) attributable to these dilutive securities is added back to Net income (controlling interest), reflecting the assumption that the securities have been converted. Issuable shares for these securities and related interest expense are excluded from the calculation if an assumed conversion would be anti-dilutive to diluted earnings per share. (s) Share-Based Compensation Plans The Company recognizes expenses for all share-based compensation arrangements based on the number of awards expected to vest. The expense for awards without performance conditions is recognized on a straight-line basis over the requisite service period, including grants that are subject to graded vesting. The Company recognizes expenses for all other arrangements on a straight-line basis for each separately vesting portion of the award. Tax windfalls or shortfalls are recorded in Income tax expense and have been classified as operating activities in the Consolidated Statements of Cash Flows. Taxes paid by the Company when it withholds shares to satisfy tax withholding obligations are classified as a financing activity in the Consolidated Statements of Cash Flows. (t) Recent Accounting Developments In June 2022, the Financial Accounting Standards Board (“FASB”) issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, which clarifies the guidance in Topic 820 on the fair value measurement of an equity security that is subject to a contractual sale restriction and requires specific disclosures related to such an equity security. The standard is effective for interim and annual periods beginning after December 15, 2023 for the Company, and is effective for interim and annual periods beginning after December 15, 2024 for the Company’s Affiliates. The Company does not expect the adoption to have a material impact on its Consolidated Financial Statements. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires disclosure of incremental segment information on an annual and interim basis for all public entities to enable investors to develop more decision- useful financial analyses. The standard is effective for annual periods beginning after December 15, 2023 and for interim periods beginning after December 15, 2024. The Company does not currently expect the adoption to have a material impact on its Consolidated Financial Statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires greater disaggregation of income tax disclosures related to the income tax rate reconciliation and income taxes paid. The standard is effective for annual periods beginning after December 15, 2024. The Company does not currently expect the adoption to have a material impact on its Consolidated Financial Statements. 2. Investments in Marketable Securities Equity Securities The following table summarizes the cost, gross unrealized gains, gross unrealized losses, and fair value of investments in equity securities: Cost Unrealized gains Unrealized losses Fair value December 31, 2022 2023 $ $ 394.4 $ 59.9 (6.4) 447.9 $ 35.3 2.6 (0.0 ) 37.9 As of December 31, 2022, investments in equity securities include ordinary shares of EQT AB (“EQT”), a public company listed on Nasdaq Stockholm (EQT.ST), with fair value of $405.1 million. The Company received the EQT shares through the sale of its equity interest in Baring Private Equity Asia (“BPEA”), in connection with the strategic combination of BPEA and EQT, which was completed in the fourth quarter of 2022. 55 Table of Contents AFFILIATED MANAGERS GROUP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) As of December 31, 2022 and 2023, investments in equity securities include consolidated Affiliate sponsored investment products with fair values of $23.5 million and $15.8 million, respectively. For the years ended December 31, 2022 and 2023, the Company recognized net unrealized gains on equity securities still held as of December 31, 2022 and 2023 of $35.5 million and $2.9 million, respectively. Debt Securities The following table summarizes the cost, unrealized gains, unrealized losses, and fair value of investments in U.S. Treasury securities classified as available-for-sale, all of which mature in 2024, and consolidated Affiliate sponsored investment products classified as trading: Cost Unrealized gains Unrealized losses Fair value Available-for-Sale Trading December 31, 2022 December 31, 2023 December 31, 2022 December 31, 2023 $ $ 252.3 $ — (1.3) 251.0 $ 405.4 $ 0.0 (0.1) 405.3 $ 19.7 $ — (1.7) 18.0 $ 17.9 — (0.1) 17.8 For the year ended December 31, 2022, there were no maturities or sales of available-for-sale securities. For the year ended December 31, 2023, the Company received $511.1 million of proceeds from the maturity of available-for-sale securities. For the years ended December 31 2022 and 2023, the Company recognized net unrealized gains (losses) on debt securities classified as trading still held as of December 31, 2022 and 2023 of $(2.2) million and $0.8 million, respectively. 3. Other Investments Other investments consists primarily of investments in funds advised by the Company’s Affiliates that are carried at NAV as a practical expedient and other investments without readily determinable fair values. Any gain or loss related to these investments is recorded in Investment and other income. Investments Measured at NAV as a Practical Expedient The Company’s Affiliates sponsor funds in which the Company and its Affiliates may make general partner and seed capital investments. These funds operate in partnership form and apply the specialized fair value accounting for investment companies. The Company accounts for its interests in these funds using the equity method of accounting and is required to retain the specialized accounting of the investment companies. Because the funds’ investments do not have readily determinable fair values, the Company uses the NAV of these investments as a practical expedient for their fair values. The following table summarizes the fair values of these investments and any related unfunded commitments: Private equity funds Investments in other strategies (1) (2) Total (3) ___________________________ December 31, 2022 December 31, 2023 Fair Value Unfunded Commitments Fair Value Unfunded Commitments $ $ 356.4 $ 14.8 371.2 $ 158.3 $ — 158.3 $ 424.4 $ 6.1 430.5 $ 187.2 — 187.2 (1) (2) The Company accounts for the majority of its interests in private equity funds one quarter in arrears (adjusted for current period calls and distributions). These funds primarily invest in a broad range of third-party funds and direct investments. Distributions will be received as the underlying assets are liquidated over the life of the funds, which is generally up to 15 years. These are multi-disciplinary funds that invest across various asset classes and strategies, including equity and credit. Investments are generally redeemable on a daily, monthly, or quarterly basis. 56 Table of Contents AFFILIATED MANAGERS GROUP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) (3) Fair value attributable to the controlling interest was $275.1 million and $324.9 million as of December 31, 2022 and 2023, respectively. Investments Without Readily Determinable Fair Values The Company made an investment in a private corporation where it does not exercise significant influence. Because this investment does not have a readily determinable fair value, the Company has elected to measure this investment at its cost minus impairments, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments in the private corporation. The following table summarizes the cost, cumulative unrealized gains, and carrying amount of investments without readily determinable fair values: Cost Cumulative unrealized gains Carrying amount For the year ended December 31, 2023, the Company recorded no gains or losses on the underlying investment. The following table presents the changes in Other investments: December 31, 2022 2023 $ $ 8.5 $ 41.9 50.4 $ 8.5 41.9 50.4 For the Years Ended December 31, 2022 2023 Measured at NAV as a Practical Expedient Without Readily Determinable Fair Values Total Measured at NAV as a Practical Expedient Without Readily Determinable Fair Values Total $ $ 324.8 $ 1.7 104.3 (59.6) 371.2 $ 50.4 $ — — — 50.4 $ 375.2 $ 1.7 104.3 (59.6) 421.6 $ 371.2 $ 34.2 82.5 (57.4) 430.5 $ 50.4 $ — — — 50.4 $ 421.6 34.2 82.5 (57.4) 480.9 Balance, beginning of period Net realized and unrealized gains Additions and commitments Sales and distributions (1) Balance, end of period ___________________________ (1) Recorded in Investment and other income. 4.

Contingent payment obligations represent the fair value of the expected future settlement amounts related to the Company’s investments in its consolidated Affiliates. Changes to assumed volatility and discount rates change the fair value of contingent payment obligations. Increases to the volatility rates used would result in higher fair values, while increases to the discount rates used would result in lower fair values. Affiliate equity purchase obligations include agreements to purchase Affiliate equity. As of December 31, 2023, there were no changes to growth or discount rates that had a significant impact to Affiliate equity purchase obligations recorded in prior periods. Other Financial Assets and Liabilities Not Carried at Fair Value The following table summarizes the Company’s other financial liabilities not carried at fair value: Senior notes Junior subordinated notes Junior convertible securities December 31, 2022 December 31, 2023 Carrying Value Fair Value Carrying Value Fair Value $ 1,098.7 $ 765.9 341.7 1,024.6 $ 552.3 346.9 1,099.4 $ 765.9 341.7 1,049.8 612.0 340.9 Fair Value Hierarchy Level 2 Level 2 Level 2 The Company has other financial assets and liabilities that are not required to be carried at fair value, but are required to be disclosed at fair value. The carrying amount of Cash and cash equivalents, Receivables, Payables and accrued liabilities, and certain Other liabilities approximates fair value because of the short-term nature of these instruments. The carrying value of the credit facilities (as defined in Note 6) approximates fair value because the credit facilities have variable interest based on selected short-term rates. 5. Investments in Affiliates and Affiliate Sponsored Investment Products Investments in Affiliates The Company’s Affiliates are consolidated or accounted for under the equity method, depending upon the underlying structure of and relationship with each Affiliate. Substantially all of the Company’s consolidated Affiliates are considered VIEs. The unconsolidated assets, net of liabilities and non-controlling interests of Affiliates accounted for under the equity method considered VIEs, and the Company’s carrying value and maximum exposure to loss, were as follows: Affiliates accounted for under the equity method $ 1,273.5 $ 2,051.6 $ 1,492.4 $ 2,198.2 December 31, 2022 December 31, 2023 Unconsolidated VIE Net Assets Carrying Value and Maximum Exposure to Loss Unconsolidated VIE Net Assets Carrying Value and Maximum Exposure to Loss 59 Table of Contents AFFILIATED MANAGERS GROUP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) As of December 31, 2022 and 2023, the carrying value and maximum exposure to loss for all of the Company’s Affiliates accounted for under the equity method was $2,139.5 million and $2,288.5 million, respectively, including Affiliates accounted for under the equity method considered VREs of $87.9 million and $90.3 million, respectively. Affiliate Sponsored Investment Products The Company’s carrying value and maximum exposure to loss from unconsolidated Affiliate sponsored investment products, is its or its consolidated Affiliates’ interests in the unconsolidated net assets of the respective products. The net assets of unconsolidated VIEs attributable to Affiliate sponsored investment products, and the Company’s carrying value and maximum exposure to loss, were as follows: Affiliate sponsored investment products $ 4,878.6 $ 15.3 $ 5,788.3 $ 29.8 December 31, 2022 December 31, 2023 Unconsolidated VIE Net Assets Carrying Value and Maximum Exposure to Loss Unconsolidated VIE Net Assets Carrying Value and Maximum Exposure to Loss 6.

The revolver matures on October 25, 2027 and the term loan matures on October 23, 2026. Subject to certain conditions, the Company may increase the commitments under the revolver by up to an additional $500.0 million and may borrow up to an additional $75.0 million under the term loan. The Company pays interest on any outstanding obligations under the credit facilities at specified rates, currently based either on an applicable term- SOFR plus a SOFR adjustment of 0.10%, or prime rate, plus a marginal rate determined based on its credit rating. As of December 31, 2023, the interest rate for the Company’s outstanding borrowings under the term loan was term-SOFR plus a SOFR adjustment of 0.10%, plus the marginal rate of 0.85%. The credit facilities contain financial covenants with respect to leverage and interest coverage, as well as customary affirmative and negative covenants, including limitations on priority indebtedness, asset dispositions, and fundamental corporate changes, and certain customary events of default. As of December 31, 2022 and 2023, the Company had no outstanding borrowings under the revolver. As of December 31, 2022 and 2023, the Company had outstanding borrowings under the term loan of $350.0 million, and the weighted average interest rate on outstanding borrowings was 5.27% and 6.31%, respectively. The Company pays commitment fees on the unused portion of its revolver. For the years ended December 31, 2022 and 2023, these fees amounted to $1.3 million. Senior Notes As of December 31, 2023, the Company had senior notes outstanding, the respective principal terms and effective interest rates of which are presented below: 60 Table of Contents Issue date Maturity date Par value (in millions) Stated coupon Coupon frequency Potential call date Call price Effective interest rate AFFILIATED MANAGERS GROUP, INC.

Junior Convertible Securities 61 Table of Contents AFFILIATED MANAGERS GROUP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) As of December 31, 2023, the Company had $341.7 million of principal outstanding in its 5.15% junior convertible trust preferred securities (the “junior convertible securities”), maturing in 2037. The junior convertible securities bear interest at a rate of 5.15% per annum, payable quarterly in cash. As of December 31, 2022 and 2023, the unamortized issuance costs related to the junior convertible securities were $3.1 million and $2.9 million, respectively. The following table presents interest expense recorded in connection with the junior convertible securities: Contractual interest expense Amortization of debt issuance costs Amortization of debt discount Total Effective interest rate For the Years Ended December 31, 2021 2022 2023 $ $ 22.2 0.4 3.1 25.7 $ $ 18.3 0.2 — 18.5 $ $ 17.6 0.2 — 17.8 5.99 % 5.21 % 5.21 % Holders of the junior convertible securities have no rights to put these securities to the Company. The holder may convert the securities to 0.2558 shares of common stock per $50.00 junior convertible security, equivalent to an adjusted conversion price of $195.47 per share. The conversion rate is subject to adjustments as described in the Amended and Restated Declaration of Trust of AMG Capital Trust II and the related indenture, both dated October 17, 2007 and filed as exhibits to this Annual Report on Form 10-K. Upon conversion, holders will receive cash or shares of the Company’s common stock, or a combination thereof, at the Company’s election. The Company may redeem the junior convertible securities if the closing price of its common stock for 20 trading days in a period of 30 consecutive trading days exceeds 130% of the then prevailing conversion price, and may also repurchase junior convertible securities in the open market or in privately negotiated transactions from time to time at management’s discretion. The junior convertible securities are considered contingent payment debt instruments under federal income tax regulations, which require the Company to deduct interest in an amount greater than its reported interest expense. The Company estimates that these deductions will generate annual deferred tax liabilities of approximately $9 million. For the year ended December 31, 2022, the Company repurchased a portion of its junior convertible securities for a purchase price of $60.9 million and as a result of these repurchases, the Company reduced its Deferred income tax liability (net) by $11.4 million. The Company did not repurchase any of its junior convertible securities during the year ended December 31, 2023. 7. Commitments and Contingencies From time to time, the Company and its Affiliates may be subject to claims, legal proceedings, and other contingencies in the ordinary course of their business activities. Any such matters are subject to various uncertainties, and it is possible that some of these matters may be resolved in a manner unfavorable to the Company or its Affiliates. The Company and its Affiliates establish accruals, as necessary, for matters for which the outcome is probable and the amount of the liability can be reasonably estimated. The Company has committed to co-invest in certain Affiliate sponsored investment products. As of December 31, 2023, these unfunded commitments were $187.2 million and may be called in future periods. As of December 31, 2023, the Company was obligated to make deferred payments and was contingently liable to make payments in connection with certain of its consolidated Affiliates, which are included in Other liabilities, as follows: Deferred payment obligations Contingent payment obligations (1) ___________________________ Controlling Interest $ 43.3 $ 12.3 Co-Investor Total 2024 2025 — $ 2.4 43.3 $ 14.7 21.7 $ 9.5 21.6 5.2 Earliest Payable (1) Fair value as of December 31, 2023.

Deferred payment obligations are included in Other liabilities. As of December 31, 2023, the Company was contingently liable to make payments of $237.1 million related to the achievement of specified financial targets by certain of its Affiliates accounted for under the equity method, of which $89.5 million may become payable in 2024 and $147.6 million may become payable from 2025 through 2029. As of December 31, 2023, the Company agreed to provide one of its Affiliates accounted for under the equity method up to $50.0 million of contingent financing. In the event that certain financial targets are not met, the Company may receive payments from one of its Affiliates accounted for under the equity method of up to $12.5 million and also has the option to reduce its ownership interest and receive an incremental payment of $25.0 million. Affiliate equity interests provide holders at consolidated Affiliates with a conditional right to put their interests to the Company over time. See Note 17. The Company and certain of its consolidated Affiliates operate under regulatory authorities that require the maintenance of minimum financial or capital requirements. The Company’s management is not aware of any significant violations of such requirements. 8.

The Company recorded amortization expense in Intangible amortization and impairments for these relationships of $35.7 million, $49.1 million, and $48.3 million for the years ended December 31, 2021, 2022, and 2023, respectively. Based on relationships existing as of December 31, 2023, the Company estimates that its consolidated amortization expense will be approximately $30 million in 2024 and approximately $25 million in each of 2025, 2026, 2027, and 2028. As of December 31, 2023, no impairments of definite-lived acquired client relationships were indicated. As of December 31, 2023, no impairments of indefinite-lived acquired client relationships were indicated. Veritable Transaction In the third quarter of 2023, the Company completed the sale of its equity interest in Veritable, LP (“Veritable”), one of the Company’s consolidated Affiliates, (the “Veritable Transaction”). Pursuant to the terms of the agreement, under which a third party acquired 100% of the outstanding equity interests in Veritable, the Company received $287.4 million in cash, net of transaction costs. Veritable is included in the Company’s results through the closing date, and the Company’s gain on the transaction was $133.1 million, which is recorded in Affiliate Transaction gains in the Consolidated Statements of Income. 9. Equity Method Investments in Affiliates In the third quarter of 2023, the Company completed a minority investment in Forbion Group Holding B.V., a private markets firm focused on investing in high-quality life sciences companies, and in the fourth quarter of 2023, the Company completed a minority investment in Ara Partners Group, LLC (“Ara Partners”), a private markets firm specializing in industrial decarbonization. The majority of the consideration paid for Ara Partners will be deductible for U.S. tax purposes over a 15-year life. The Company’s provisional purchase price allocation for each investment was measured using financial models that include assumptions of expected market performance, net client cash flows, and discount rates. The financial results of certain Affiliates accounted for under the equity method are recognized in the Consolidated Financial Statements one quarter in arrears. Equity method investments in Affiliates (net) consisted of the following: Goodwill Definite-lived acquired client relationships (net) Indefinite-lived acquired client relationships (net) Undistributed earnings and tangible capital Equity method investments in Affiliates (net) The following table presents the change in Equity method investments in Affiliates (net): 64 December 31, 2022 2023 1,262.4 $ 479.4 119.0 278.7 2,139.5 $ 1,323.3 652.5 122.6 190.1 2,288.5 $ $ Table of Contents AFFILIATED MANAGERS GROUP, INC.

Definite-lived acquired client relationships at the Company’s Affiliates accounted for under the equity method are amortized over their expected period of economic benefit. The Company recorded amortization expense for these relationships of $123.0 million, $109.1 million, and $86.0 million for the years ended December 31, 2021, 2022, and 2023, respectively. Based on relationships existing as of December 31, 2023, the Company estimates the amortization expense attributable to its Affiliates will be approximately $65 million in 2024, approximately $62 million in 2025, approximately $55 million in each of 2026 and 2027, and approximately $50 million in 2028. For the year ended December 31, 2022, the Company recorded a $50.0 million expense to reduce the carrying value of an Affiliate to fair value. The decline in the fair value was a result of a decline in assets under management and a reduction in projected margin, which decreased the forecasted income associated with the investment. The fair value of the investment was determined using a probability-weighted discounted cash flow analysis, a Level 3 fair value measurement that included a projected compounded growth in assets under management over the first five years of 2%, long-term growth rate of 5%, discount rates of 11% and 20% for asset- and performance-based fees, respectively, and a market participant tax rate of 25%. Based on the discounted cash flow analysis, the Company concluded that the fair value of its investment had declined below its carrying value and that the decline was other-than- temporary. For the year ended December 31, 2023, the Company recorded $9.6 million of expenses to reduce the carrying values of certain of its Affiliates because it concluded that the fair value of its investments had declined below their carrying values and that the declines were other-than-temporary. For the year ended December 31, 2023, the Company completed its annual assessment of its investments in Affiliates accounted for under the equity method and no other impairments were indicated. The Company had 20 and 22 Affiliates accounted for under the equity method as of December 31, 2022 and 2023, respectively. The majority of these Affiliates are partnerships with structured interests that define how the Company will participate in Affiliate earnings, typically based upon a fixed percentage of revenue reduced by, in some cases, certain agreed-upon expenses. The partnership agreements do not define a fixed percentage for the Company’s ownership of the equity of the Affiliate. These percentages would be subject to a separate future negotiation if an Affiliate were to be sold or liquidated. The following table presents summarized financial information for Affiliates accounted for under the equity method: 65 Table of Contents AFFILIATED MANAGERS GROUP, INC.

Pursuant to the terms of the Securities Purchase and Merger Agreement with EQT, under which the Company and each of the other owners agreed to sell their respective equity interests in BPEA, the Company received $223.6 million in cash, net of transaction costs, and 28.68 million EQT ordinary shares (25% of which were subject to a six- month lock-up, which expired in April 2023), and other investments. BPEA is included in the Company’s results through the closing date, and the Company’s gain on the transaction was $641.9 million, which is recorded in Affiliate Transaction gains. 10.

The Company may invest from time to time in funds or products advised by its Affiliates. The Company’s executive officers and directors may invest from time to time in funds advised or products offered by its Affiliates, or receive other investment services provided by its Affiliates, on substantially the same terms as other participating investors. In addition, the Company and its Affiliates earn asset- and performance-based fees and incur distribution and other expenses for services provided to Affiliate sponsored investment products. Affiliate management owners and the Company’s officers may serve as trustees or directors of certain investment vehicles from which the Company or an Affiliate earns fees. Also, from time to time, the Company may enter into ordinary course engagements for capital markets, banking, brokerage, and other services with beneficial owners of 5% or more of the Company’s voting securities. The Company has related party transactions in association with its deferred and contingent payment obligations, and Affiliate equity transactions, as more fully described in Notes 7, 9, 16, and 17. 14. Stockholders’ Equity Common Stock The Company is authorized to issue up to 150.0 million shares of voting common stock and 3.0 million shares of class B non-voting common stock. 67 Table of Contents AFFILIATED MANAGERS GROUP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) The Company’s Board of Directors authorized share repurchase programs in January 2022, October 2022, and October 2023 to repurchase up to 2.0 million, 3.0 million, and 3.3 million shares of its common stock, respectively, and these authorizations have no expiry. Purchases may be made from time to time, at management’s discretion, in the open market or in privately negotiated transactions, including through the use of trading plans, as well as pursuant to accelerated share repurchase programs or other share repurchase strategies that may include derivative financial instruments. As of December 31, 2023, the Company had repurchased all of the shares in the repurchase program authorized in January 2022, and there were a total of 4.2 million shares available for repurchase under the Company’s share repurchase programs. In December 2022, the Company entered into an accelerated share repurchase agreement to repurchase shares of its common stock in exchange for an upfront payment of $225.0 million. The Company received an initial share delivery of 1.1 million shares in December 2022, which represented 80% of the upfront payment based on the closing price of the Company’s common stock on the agreement date. In the second quarter of 2023, the Company received a final share delivery of 0.4 million shares. Under this agreement, the Company repurchased a total of 1.5 million shares at an average price of $147.29 per share. The following is a summary of the Company’s share repurchase activity: Year 2021 2022 2023 Equity Distribution Program Shares Repurchased Average Price 3.5 $ 4.5 3.0 146.54 144.45 132.99 In the second quarter of 2022, the Company entered into equity distribution and forward equity agreements with several major securities firms under which it may, from time to time, issue and sell shares of its common stock (immediately or on a forward basis) having an aggregate sales price of up to $500.0 million (the “equity distribution program”). This equity distribution program superseded and replaced the Company’s prior equity distribution program. As of December 31, 2023, no sales had occurred under the equity distribution program. Preferred Stock The Company is authorized to issue up to 5.0 million shares of preferred stock. Any such preferred stock issued by the Company may rank prior to common stock as to dividend rights, liquidation preference or both, may have full or limited voting rights, and may be convertible into shares of common stock. Financial Instruments The Company’s junior convertible securities contain an embedded right for holders to receive shares of the Company’s common stock under certain conditions. These arrangements, as well as the equity distribution program, meet the definition of equity and are not required to be accounted for separately as derivative financial instruments. 15. Share-Based Compensation Share-Based Incentive Plans The Company has established various plans under which it is authorized to grant restricted stock, restricted stock units, stock options, and stock appreciation rights. The Company may also grant cash awards that can be notionally invested in one or more specified measurement funds, including the Company’s common stock. Awards granted under the Company’s share-based incentive plans typically participate in any dividends declared, but such amounts are deferred until delivery of the shares and are forfeitable if the requisite service is not satisfied. Dividends may accrue in cash or may be reinvested in the Company’s common stock. Share-Based Compensation The following table presents share-based compensation expense: 68 Table of Contents Year 2021 2022 2023 AFFILIATED MANAGERS GROUP, INC.

As of December 31, 2022, the Company had unrecognized share-based compensation expense of $64.7 million. As of December 31, 2023, the Company had unrecognized share-based compensation of $54.4 million, which will be recognized over a weighted average period of approximately two years (assuming no forfeitures). Restricted Stock The following table summarizes transactions in the Company’s restricted stock units: Unvested units–December 31, 2022 Units granted Units vested Units forfeited Performance condition changes Unvested units–December 31, 2023 Restricted Stock Units Weighted Average Grant Date Value 1.1 0.3 (0.5) (0.0 ) 0.0 0.9 $ $ 106.88 159.51 85.07 132.81 129.15 138.51 The Company granted restricted stock units with fair values of $32.3 million, $47.1 million, and $49.3 million for the years ended December 31, 2021, 2022, and 2023, respectively. These restricted stock units were valued based on the closing price of the Company’s common stock on the grant date and the number of shares expected to vest. Restricted stock units containing vesting conditions generally require service over a period of three years to four years and may also require the satisfaction of certain performance conditions. For awards with performance conditions, the number of restricted stock units expected to vest may change over time depending upon the performance level achieved. The total fair value of shares vested was $51.7 million, $54.6 million, and $86.2 million for the years ended December 31, 2021, 2022, and 2023, respectively. As of December 31, 2023, the Company had 2.4 million shares available for grant under its plans.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued) The Company granted stock options with fair values of $2.0 million and $1.8 million for the years ended December 31, 2021 and 2022, respectively. The Company did not grant any stock options for the year ended December 31, 2023. Stock options generally vest over a period of three years to five years and expire seven years after the grant date. All stock options have been granted with exercise prices equal to the closing price of the Company’s common stock on the grant date. Substantially all of the Company’s outstanding stock options contain both service and performance conditions. For awards with performance conditions, the number of stock options expected to vest may change over time depending upon the performance level achieved. The Company generally uses treasury stock to settle stock option exercises. The total intrinsic value of stock options exercised for the years ended December 31, 2021, 2022, and 2023 was $13.4 million, $1.2 million, and $0.2 million, respectively. The cash received for stock options exercised was $3.6 million, $2.6 million, and zero for the years ended December 31, 2021, 2022, and 2023, respectively. As of December 31, 2023, the intrinsic value of exercisable stock options outstanding was $1.9 million, and 1.1 million options were available for grant under the Company’s option plans. The weighted average fair value of stock options granted was $54.19 and $47.84 per option for the years ended December 31, 2021 and 2022, respectively. The Company uses the Black-Scholes option pricing model to determine the fair value of options. The weighted average grant date assumptions used to estimate the fair value of stock options granted were as follows: (1) Dividend yield Expected volatility Risk-free interest rate Expected life of stock options (in years) Forfeiture rate (2) (3) For the Years Ended December 31, 2021 2022 0.0 % 37.1 % 1.0 % 5.7 0.0 % 0.0 % 36.8 % 1.7 % 5.7 0.0 % ___________________________ (1) (2) (3) Expected volatility is based on historical and implied volatility. Risk-free interest rate is based on the U.S. Treasury yield curve in effect at the date of grant. Expected life of options (in years) is based on the Company’s historical and expected exercise behavior. 16. Redeemable Non-Controlling Interests Affiliate equity interests provide holders with an equity interest in one of the Company’s Affiliates, consistent with the structured partnership interests in place at the respective Affiliate. Affiliate equity holders generally have a conditional right to put their interests to the Company at certain intervals (between five years and 15 years from the date the equity interest is received by the Affiliate equity holder or on an annual basis following an Affiliate equity holder’s departure). Prior to becoming redeemable, the Company’s Affiliate equity is included in Non-controlling interests. Upon becoming redeemable, these interests are reclassified to Redeemable non-controlling interests at their current redemption values. Changes in the current redemption value are recorded to Additional paid-in capital. When the Company has an unconditional obligation to purchase Affiliate equity interests, the interests are reclassified from Redeemable non-controlling interest to Other liabilities at current fair value. Changes in fair value are recorded to Other expenses (net). The following table presents the changes in Redeemable non-controlling interests: 70 Table of Contents AFFILIATED MANAGERS GROUP, INC.

Affiliate Equity Affiliate equity interests are allocated income in a manner that is consistent with the structured partnership interests in place at the respective Affiliate. The Company’s Affiliates generally pay quarterly distributions to Affiliate equity holders. Distributions paid to non-controlling interest Affiliate equity holders were $334.3 million, $341.9 million, and $271.3 million for the years ended December 31, 2021, 2022, and 2023, respectively. Affiliate equity interests provide the Company a conditional right to call (following an Affiliate equity holder’s departure) and Affiliate equity holders have a conditional right to put their interests at certain intervals (including on an annual basis following an Affiliate equity holder’s departure). The Company has the right to settle a portion of these purchases in shares of its common stock. For Affiliates accounted for under the equity method, the Company does not typically have such put and call arrangements. The purchase price of these conditional purchases are generally calculated based upon a multiple of cash flow distributions, which is intended to represent fair value. Affiliate equity holders are also permitted to sell their equity interests to other individuals or entities in certain cases, subject to the Company's approval or other restrictions. The Company, at its option, may pay for Affiliate equity purchases in cash, shares of its common stock, or other forms of consideration, and can consent to the transfer of these interests to other individuals or entities. The Company periodically purchases Affiliate equity from and issues Affiliate equity to the Company’s consolidated Affiliate partners and other parties. The amount of cash paid for purchases was $150.5 million, $61.5 million, and $67.4 million for the years ended December 31, 2021, 2022, and 2023, respectively. The total amount of cash received for issuances was $117.7 million (including $99.6 million from a co-investor), $15.2 million, and $13.4 million for the years ended December 31, 2021, 2022, and 2023, respectively. Sales and purchases of Affiliate equity generally occur at fair value; however, the Company also grants Affiliate equity to its consolidated Affiliate partners and other parties as a form of compensation. If the equity is issued for consideration below the fair value of the equity, or purchased for consideration above the fair value of the equity, the difference is recorded as compensation expense in Compensation and related expenses in the Consolidated Statements of Income over the requisite service period. The following table presents Affiliate equity compensation expense: Controlling interest Non-controlling interests Total The following table presents unrecognized Affiliate equity compensation expense: 71 For the Years Ended December 31, 2021 2022 2023 $ $ 17.4 $ 45.9 63.3 $ 5.0 $ 46.4 51.4 $ 13.6 39.1 52.7 Table of Contents Year 2021 2022 2023 AFFILIATED MANAGERS GROUP, INC.

The total receivable was $11.6 million and $5.9 million as of December 31, 2022 and 2023, respectively, and was included in Other assets. The total payable was $24.5 million and $53.9 million as of December 31, 2022 and 2023, respectively, and was included in Other liabilities. Effects of Changes in the Company’s Ownership in Affiliates The Company periodically acquires interests from, and transfers interests to, Affiliate equity holders. Because these transactions do not result in a change of control, any gain or loss related to these transactions is recorded to Additional paid-in capital, which increases or decreases the controlling interest’s equity. No gain or loss related to these transactions is recorded in the Consolidated Statements of Income or the Consolidated Statements of Comprehensive Income. While the Company presents the current redemption value of Affiliate equity within Redeemable non-controlling interests, with changes in the current redemption value increasing or decreasing the controlling interest’s equity over time, the following table presents the cumulative effect that ownership changes had on the controlling interest’s equity related only to Affiliate equity transactions that occurred during the applicable periods: Net income (controlling interest) Decrease in controlling interest paid-in capital from Affiliate equity issuances Decrease in controlling interest paid-in capital from Affiliate equity purchases Net income (controlling interest) including the net impact of Affiliate equity transactions 18. Benefit Plans For the Years Ended December 31, 2021 2022 2023 $ $ 565.7 $ (17.5) (63.2) 485.0 $ 1,145.9 $ (0.2) (38.2) 1,107.5 $ 672.9 (13.5) (50.4) 609.0 The Company has a defined contribution plan that is a qualified employee profit-sharing plan, covering substantially all of its employees. Under this plan, the Company is able to make discretionary contributions for the benefit of its employees that are qualified plan participants, up to Internal Revenue Service (“IRS”) limits. The Company’s consolidated Affiliates generally have their own qualified defined contribution retirement plans covering their respective employees or, for several Affiliates, had their employees covered under the Company’s plan until February or March 2023, as applicable. In each case, the relevant Affiliate was able to make discretionary contributions for the benefit of its employees, as applicable, that were qualified plan participants, up to IRS limits. Consolidated expenses related to these plans were $19.1 million, $20.9 million, and $24.8 million for the years ended December 31, 2021, 2022, and 2023, respectively. The controlling interest’s portion of expenses related to these plans were $3.0 million, $3.4 million, and $3.6 million for the years ended December 31, 2021, 2022, and 2023, respectively. 19. Income Taxes The Company’s consolidated income tax provision includes taxes attributable to the controlling interest and, to a lesser extent, taxes attributable to the non-controlling interests.

The Company’s effective tax rate (controlling interest) in 2021 is higher than the marginal tax rate, primarily due to non-deductible compensation expense and an increase in deferred tax expense resulting from the revaluation of certain deferred tax liabilities due to an increase in the UK tax rate enacted during 2021. The effective tax rate (controlling interest) in 2022 is lower than the marginal rate primarily due to the tax benefits of foreign operations and a state tax benefit related to the BPEA Transaction. The effective tax rate (controlling interest) in 2023 is lower than the marginal rate primarily due to discrete benefits from foreign operations. Deferred income tax liability (net) reflects the expected future tax consequences of temporary differences between the financial reporting bases and tax bases of the Company’s assets and liabilities. The significant components of the Company’s Deferred income tax liability (net) are as follows: 74 Table of Contents AFFILIATED MANAGERS GROUP, INC.

As of December 31, 2023, the Company had available state net operating loss carryforwards of $228.2 million, a majority of which will expire over six years to 11 years. As of December 31, 2023, the Company had foreign loss carryforwards of $74.8 million, of which $57.5 million will expire over nine years to 16 years and $17.3 million will carry forward indefinitely. As of December 31, 2023, the Company had foreign tax credit carryforwards of $16.0 million, a majority of which will expire over five years to eight years. The Company believed it was more-likely-than-not that the benefit from certain state and foreign loss carryforwards and foreign tax credit carryforwards would not be fully realized, and, as of December 31, 2023, had valuation allowances of $14.6 million, $17.0 million, and $16.0 million on the state and foreign loss carryforwards and the foreign tax credit carryforwards, respectively. For the years ended December 31, 2022 and 2023, the Company increased its valuation allowance $4.2 million and $0.5 million, respectively. The Company’s estimates and assumptions regarding the realization of its state and foreign loss carryforwards do not contemplate certain changes in ownership of the Company’s stock which could limit the utilization of these carryforwards. The Company provides for U.S. income taxes on all foreign earnings. The Company does not provide for U.S. income taxes on the portion of the excess of the financial reporting bases over tax bases in the Company’s investments in foreign subsidiaries considered permanent in duration. Such amount would generally become taxable upon the repatriation of assets from, or a sale or liquidation of, the foreign subsidiaries. While a determination of the potential amount of unrecognized deferred U.S. income tax liability related to these amounts is not practicable because of the numerous assumptions associated with this hypothetical calculation, as of December 31, 2023, the estimated amount of such difference was $347.7 million. A reconciliation of the changes in unrecognized tax benefits is as follows: 75 Table of Contents AFFILIATED MANAGERS GROUP, INC.

As of December 31, 2023 certain of these benefits, if realized, would be offset by the utilization of indirect tax benefits, for which the Company has accrued deferred tax assets of $10.0 million. The Company records accrued interest and penalties, if any, related to unrecognized tax benefits in Income tax expense. For the years ended December 31, 2021, 2022, and 2023 interest and penalties related to unrecognized tax benefits were $(0.4) million, $2.6 million, and $0.8 million, respectively. As of December 31, 2022 and 2023, the Company accrued interest and penalties related to unrecognized tax benefits of $13.6 million and $14.4 million, respectively. The Company is subject to U.S. federal, state and local, and foreign income tax in multiple jurisdictions and is periodically subject to tax examinations in these jurisdictions. The completion of examinations may result in the payment of additional taxes and/or the recognition of tax benefits. The Company is generally no longer subject to income tax examinations by U.S. federal, state and local, or foreign taxing authorities for periods prior to 2017. In August 2022, the Inflation Reduction Act was enacted into law and included provisions for a 15% corporate alternative minimum income tax and a 1% excise tax on repurchases of the Company’s common stock. These provisions, which were effective for the Company beginning January 1, 2023, did not have a material impact on the Company’s Consolidated Financial Statements for the year ended December 31, 2023. The Company records the excise tax as part of the cost basis of its common stock repurchased. 20. Earnings Per Share The calculation of Earnings per share (basic) is based on the weighted average number of shares of the Company’s common stock outstanding during the period. Earnings per share (diluted) is similar to Earnings per share (basic), but adjusts for the dilutive effect of the potential issuance of incremental shares of the Company’s common stock. The following is a reconciliation of the numerator and denominator used in the calculation of basic and diluted earnings per share available to common stockholders: 76 Table of Contents AFFILIATED MANAGERS GROUP, INC.

Changes in and Disagreements with Accountants on Accounting and Financial Disclosure None. Item 9A. Controls and Procedures As required by Rule 13a-15 of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”), as of December 31, 2023, we carried out an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures are effective in ensuring that (i) information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and (ii) such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, we recognize that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management necessarily was required to apply its judgment in evaluating and implementing possible controls and procedures. Our disclosure controls and procedures were designed to provide reasonable assurance of achieving their stated objectives, and our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level. We review on an ongoing basis and document our disclosure controls and procedures, and our internal control over financial reporting, and we may from time to time make changes in an effort to enhance their effectiveness and ensure that our systems evolve with our business. See “Management’s Report on Internal Control over Financial Reporting” in Item 8. Our independent registered public accounting firm, PricewaterhouseCoopers LLP, has issued an audit report on our internal control over financial reporting, which is included in Item 8. No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the fiscal quarter ended December 31, 2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

(the “Company”) hereby grants to the Grantee named above, who is a non-executive member of the Board of Directors of the Company (a “Director” and the “Board”) as of the date hereof, an Award (the “Award”) of restricted stock units (each a “Unit”, and collectively, the “Units”), consisting of the right to receive a distribution of the number of shares of common stock, par value $0.01 per share, of the Company (the “Shares”) specified on the attached Exhibit A, which is hereby incorporated by reference (“Exhibit A”), to be issued and distributed to the Grantee according to the terms set forth herein and in the Plan. 1. Vesting. Except as set forth below, and subject to the discretion of the Administrator to accelerate the vesting schedule hereunder, the Units shall vest in the amounts and on the date(s) indicated on Exhibit A; provided that, Grantee’s service as a Director is through the applicable vesting date set forth on Exhibit A. 2. Vesting and Distribution. The Units shall be distributed only in Shares, such that the Grantee shall be entitled to receive one Share for each vested Unit. The Shares subject to this Award shall be issued and distributed to the Grantee pursuant to Section 1 hereof, and the vesting schedule set forth on Exhibit A, with such issuance and distribution of the Shares (whether the Shares are to be held by the Company on the Grantee’s behalf pursuant to Section 6(b) hereof or issued directly to the Grantee) to occur, in all cases, no later than March 15 of the year following the year in which the Units vest, in accordance with the short-term deferral exception under Code Section 409A and the regulations and guidance thereunder. Any sales of Shares subject to this Award are subject to the Company’s insider trading policy, equity ownership guidelines, and other Company policies as may be in effect from time to time or otherwise established by the Administrator. 3. Dividend Equivalent Rights. If the Company makes any cash dividends or other cash distributions to the holders of Shares of the Company’s common stock, the Grantee shall have the right to receive payments in lieu thereof in respect of the Units subject to this Award (“Dividend Equivalent Rights”). If the Company makes such a cash dividend or other cash distribution prior to the issuance and distribution of the Shares subject to this Award or prior to termination of the Award, the Company shall credit a bookkeeping account of the Dividend Equivalent Rights on behalf of the Grantee as of the record date of such cash dividend or other cash distribution. The amount credited shall be equal to the per-Share cash dividend or other cash distribution paid by the Company multiplied by the total number of then outstanding Units. Such amounts shall be subject to the same vesting, payment (without interest), issuance, distribution, and other terms and conditions of the Units to which they relate as provided in this Agreement. References in this Agreement to Units shall, as appropriate, include any Dividend Equivalent Rights described in this Section 3. 4. Termination of Service. If the Grantee ceases to be a Director, this Award may be subject to earlier termination, accelerated vesting, or post-termination vesting, as set forth below. (a) Termination by Reason of Death or Disability; Retirement. If the Grantee ceases to be a Director by reason of (i) death or disability, the Units subject to this Award shall automatically fully vest at the time of such termination, or (ii) the Grantee’s retirement at the end of the applicable term or other voluntary cessation of service [and the Grantee has completed seven (7) years of service on the Board] (“Retirement”), this Award shall, to the extent unvested as of the effective date of such Retirement, remain outstanding and shall continue to vest in accordance with the original vesting schedule set forth set forth on Exhibit A. (b) Other Termination. If the Grantee ceases to be a Director for any reason other than (i) death or disability or (ii) Retirement, this Award shall, to the extent not already vested as described herein, terminate immediately and be of no further force or effect. The Administrator’s determination of the reason that the Grantee has ceased to be a Director shall be conclusive and binding on the Grantee and the Grantee’s representatives, legal guardians, or legatees. 5. Transferability. This Agreement is personal to the Grantee, is non-assignable and is not transferable in any manner, by operation of law or otherwise, other than by will or the laws of descent and distribution or as permitted by the Administrator (or its delegee). The Grantee may transfer, without consideration for the transfer, the Award to members of the Grantee’s immediate family, to trusts for the benefit of such family members, or to partnerships in which such family members are the only partners, provided that the transferee (and, as required by the Administrator, the beneficiaries or members of such transferee) agrees in writing with the Company to be bound by all of the terms and conditions of the Plan and this Agreement. 6. Miscellaneous. (a) The Units are subject to adjustment in accordance with the provisions of Section 7 of the Plan. (b) The Company shall maintain an account on its books in the name of the Grantee which shall reflect the number of Units awarded to the Grantee and the number of Shares the Grantee is eligible to receive thereunder. The Grantee acknowledges and agrees that the Company, in its sole discretion, may (i) hold all vested Units and all Shares issued and distributed in respect thereof pursuant to this Award on behalf of the Grantee, until such time as the Grantee submits a request for delivery, and in such case, will exercise voting rights and take all other corporate actions for any Shares issued pursuant to this Award for such time as such Shares may be held by the Company on behalf of the Grantee, unless the Grantee provides written notice to AMG Human Resources to the contrary, or (ii) release any such Shares issued and distributed in respect hereof pursuant to this Award to the Company’s designated broker, and such broker may hold such Shares until such time as they are distributed to the Grantee. The Grantee further agrees to follow such administrative procedures as may be established from time to time by the Company and/or its designated broker. (c) Notice hereunder shall be given to the Company at its principal place of business, and shall be given to the Grantee at the address on file in the Company’s records, or in either case at such other address as one party may subsequently furnish to the other party in writing. (d) Pursuant to Section 10 of the Plan, the Administrator may at any time amend or cancel any outstanding portion of this Award for any purpose that may at the time be permitted by law, but no such action may be taken that materially and adversely affects the Grantee’s rights under this Agreement without the Grantee’s consent. 2 (e) This Award shall not be interpreted to bestow upon the Grantee any equity interest or ownership in the Company or any subsidiary or Affiliate prior to the dates on which the Company delivers Shares to the Grantee. The Grantee shall have no rights as a stockholder with respect to the Units, and shall have the rights of a stockholder only as to those Shares, if any, that are actually delivered under this Award. (f) If the Grantee is resident outside of the United States, to the extent permitted by applicable law, the Grantee hereby consents to the holding, processing, and transfer of data relating to the Grantee (including sensitive personal data as defined in the UK Data Protection Act 1998) by: (i) the Company; (ii) any person providing services to the Company (including, but not limited to, any third party broker, registrar, or administrator); and (iii) any trustee appointed by the Company for all purposes relating to the administration or operation of the Plan, including the grant, holding, or vesting of an Award and the delivery, holding, or sale of Stock and, to the extent permitted by applicable law, this consent includes consent to the transfer of such data to countries outside the European Economic Area even if the country in question does not maintain adequate data protection standards. (g) The provisions of this Agreement and all claims or disputes arising out of or based upon this Agreement or relating to the subject matter hereof or thereof will be governed by and construed in accordance with the domestic substantive laws of the State of Delaware without giving effect to any choice or conflict of laws provision or rule that would cause the application of the domestic substantive laws of any other jurisdiction. (h) Notwithstanding anything herein to the contrary, this Award shall be, and the Grantee hereby acknowledges that it is, subject to and governed by all the terms and conditions of the Plan. Except as otherwise expressly provided, all terms used herein shall have the same meaning as in the Plan, as applicable and as may be amended from time to time.

(the “Company”) hereby grants to the optionee named on Exhibit A hereto (the “Optionee”) an option (the “Stock Option”) to purchase on or prior to the Expiration Date specified on Exhibit A all or part of the number of shares of common stock, par value $0.01 per share, of the Company (such stock, the “Stock”, and such shares, the “Option Shares”) specified on Exhibit A at the Option Exercise Price per Share specified on Exhibit A, to be issued and distributed to the Optionee according to the terms set forth herein and in the Plan, and the vesting schedule and performance requirements (if any) set forth herein. This Stock Option is intended to be an “incentive stock option” within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), to the extent permitted by Section 6(b)(viii) of the Plan and is granted to the Optionee in connection with the Optionee’s Employment by the Company or a “subsidiary” corporation of the Company, as such term is defined in Section 424 of the Code. 1. Vesting; Exercisability and Performance Measure. (a) Vesting. Except as set forth below, and subject to the discretion of the Administrator to accelerate the vesting schedule, this Stock Option shall become vested with respect to the number of Option Shares on the dates indicated on Exhibit A; provided that, Optionee’s Employment is through the applicable vesting date or this Stock Option qualifies as a Retirement Eligible Award, in each case, as set forth on Exhibit A. In addition, if this Stock Option is subject to a Performance Measure (but not otherwise), Section 1(b) shall apply. For the avoidance of doubt, the vesting of this Stock Option may be accelerated automatically in certain circumstances described herein. (b) Exercisability and Performance Measure. No portion of this Stock Option may be exercised unless such portion has vested. Further, if this Stock Option is subject to a Performance Measure (as defined herein), vested portions of this Stock Option shall be exercisable only if the Compensation Committee has certified the attainment of the Performance Measure with respect to all or any portion thereof, and following such certification shall be exercisable into the number of Option Shares set forth on Exhibit A; it being understood that if vesting of this Stock Option is accelerated or continued post-termination, as the case may be, pursuant to Sections 1(c)(y), 4(a)(ii), 4(b), or 4(c) hereof, such Stock Option shall remain subject to the attainment of the Performance Measure, and this Stock Option shall not be exercisable unless and until the Compensation Committee has certified that the Performance Measure has been attained with respect to all or any portion thereof and following such certification shall be exercisable into the number of Option Shares set forth on Exhibit A. If such Performance Measure remains in effect and the Compensation Committee certifies that it has not been attained with respect to all or any portion of this Stock Option (including any portion of this Stock Option that has vested pursuant to Sections 1(c)(y), 4(a)(ii), 4(b), or 4(c) hereof), this Stock Option shall terminate immediately and be of no further force or effect with respect to all of the Option Shares or such portion thereof, as applicable. (c) Change of Control. Notwithstanding anything to the contrary herein or in the Plan, in the event of termination of the Optionee’s Employment (i) by the Company without Cause or (ii) by the Optionee for Good Reason, in either case occurring within the two-year period following a Change of Control, this Stock Option shall automatically fully vest at the time of such termination; provided that, if subject to a Performance Measure, this Stock Option shall only be exercisable pursuant to this Section 1(c) if (x) the Compensation Committee has certified that the Performance Measure has been attained with respect to all or any portion thereof on or before the date of termination, and in such case shall vest at the time of such termination and shall be exercisable into the number of Option Shares set forth on Exhibit A, or (y) the attainment of the Performance Measure is not yet determinable as of such date, and in such case shall fully vest at the time of such termination but the vested Stock Option shall remain subject to the attainment of the Performance Measure and shall not be exercisable unless and until the Compensation Committee has certified that the Performance Measure has been attained with respect to all or any portion thereof, and following such certification shall be exercisable into the number of Option Shares set forth on Exhibit A. (For the avoidance of doubt, if this Stock Option (including any portion thereof that vested pursuant to sub-clause (y) above) is subject to a Performance Measure that the Compensation Committee has certified has not been attained with respect to all or any portion thereof, this Stock Option shall terminate with respect to all of the Option Shares or such portion thereof, as applicable, in accordance with Section 1(b) hereof.) 2. Manner of Exercise. (a) The Optionee may exercise this Stock Option only in the following manner: from time to time on or prior to the Expiration Date of this Stock Option, the Optionee may give written notice to the Chief Administrative Officer or General Counsel and/or principal legal officer of the Optionee’s election to purchase some or all of the vested Option Shares purchasable at the time of such notice. Such notice shall specify the number of Option Shares to be purchased. Payment of the purchase price for the Option Shares may be made by one or more of the following methods: (i) in cash or by certified or bank check or other instrument acceptable to the Administrator; (ii) through the delivery of previously acquired unrestricted shares of Stock, or the withholding of unrestricted shares of Stock otherwise deliverable upon exercise, in either case, that have an aggregate Fair Market Value equal to the exercise price; (iii) by the Optionee delivering to the Company a properly executed exercise notice in a form acceptable to the Company together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company to pay the option purchase price; provided that, in the event the Optionee chooses to pay the option purchase price as so provided, the Optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as the Administrator shall prescribe as a condition of such payment procedure and shall comply with all applicable laws, which laws may in certain cases restrict the availability of this method; or (iv) a combination of (i), (ii), and (iii) above. Payment instruments will be received subject to collection. Stock Option exercises and any sales of Option Shares will be subject to the Company’s insider trading policy, equity ownership guidelines, and other Company policies as may be in effect from time to time or otherwise established by the Administrator. (b) The issuance of Stock representing the Option Shares will be contingent upon the Company’s receipt from the Optionee of full payment for the Option Shares, as set forth above, and any agreement, statement, or other evidence that the Company and/or the Administrator may require to satisfy itself that the issuance of Stock to be purchased pursuant to the exercise of this Stock Option and any subsequent resale of the shares of Stock will be in compliance with all applicable laws and regulations and with the requirements hereof and of the Plan.

The amount of the Liquidated Damages represents a reasonable estimate of the damages expected to be suffered by the Company and its subsidiaries and Affiliates as a result of the Optionee’s default and, in any such event, in addition to (and not in limitation of) such other remedies as the Company may have against the Optionee, until the Liquidated Damages are recovered in their entirety, (x) the 11 Company shall be entitled to withhold any payments to which the Optionee otherwise would be entitled (whether pursuant to this Agreement or any other agreement, plan, or policy, including without limitation distributions hereunder), and (y) the Optionee, at the request of the Company, shall return all or some incentive compensation (which shall include any compensation distributed or awarded to the Optionee other than base compensation); provided that, any amounts so withheld or returned shall be promptly released to the original payee to the extent it is determined (whether by settlement, judgment, or arbitral decision) that such amounts are required to be so released, together with interest thereon as may be agreed or determined in connection with such settlement, judgment, or decision. The Optionee agrees that the remedies provided in this Section 6 are reasonably related to anticipated losses that the Company and/or any of its subsidiaries or Affiliates would suffer upon a breach of such provisions by the Optionee. The Optionee recognizes and agrees that the Company’s remedies at law for any breach, or threatened breach, of the provisions of this Agreement would be inadequate, and that for any breach or threatened breach of such provisions by the Optionee, the Company shall, in addition to such other remedies as may be available to it at law or in equity or as provided in this Agreement, be entitled to injunctive relief and enforcement of its rights by an action for specific performance to the extent permitted by law (and without having to post bond), and to an award of reasonable attorneys’ fees and costs incurred in connection with securing any of its rights hereunder. Notwithstanding the foregoing, the Optionee recognizes and agrees that if this Stock Option qualifies as a Retirement Eligible Award, as set forth on Exhibit A, the Retirement Policy, to the extent applicable, may provide for alternative remedies upon any breach of the terms and conditions set forth therein. 7. (a) Notice of Termination. The Optionee’s Employment may be terminated at any time by the Company or, if different, any subsidiary or Affiliate of the Company that is the Optionee’s employer (the “Optionee’s employer”), or by the Optionee; provided that, the Optionee (but not the Company or, if different, the Optionee’s employer) shall be required to provide at least six (6) months advance written notice of such termination. For the avoidance of doubt, for purposes of Section 5 of this Agreement, termination of Employment shall be deemed to occur upon delivery of notice of termination by the Optionee. (b) Where notice of termination has been delivered by the Optionee, the Company and, if different, the Optionee’s employer shall be under no obligation to provide any activities to Optionee to carry out on behalf of the Company or its subsidiaries or Affiliates, and may require the Optionee (i) not to attend any premises of the Company or any subsidiary or Affiliate thereof, (ii) to resign with immediate effect from any offices the Optionee holds with the Company or any subsidiary or Affiliate thereof (or any Client thereof), (iii) to refrain from any business contact with any Clients, partners, or employees of the Company or any subsidiary or Affiliate thereof, and (iv) to take any leave time the Optionee has accrued under the policies of the Company (or any of its subsidiaries or Affiliates, as applicable). (c) Notwithstanding the foregoing, if the Optionee is a party to an employment agreement with the Company or any subsidiary or Affiliate thereof, and/or if this Stock Option qualifies as a Retirement Eligible Award, as set forth on Exhibit A, any applicable terms of such employment agreement and/or the Retirement Policy, as applicable, shall supersede and apply in precedence to the provisions of clauses (a) and (b) of this Section 7, and clauses (a) and (b) of this Section 7 shall not be taken to amend the related terms of such employment agreement and/or the Retirement Policy, as applicable. (d) In connection with the termination of the Optionee’s Employment, the Optionee shall reasonably cooperate with the Company and, if different, the Optionee’s employer, to prepare a communication plan regarding the Optionee’s departure, and the Optionee shall not make any other public statement regarding the Optionee’s departure without the prior written consent of the Company. 12 8. Nondisparagement. In exchange for the consideration herein, the Optionee agrees not to make any disparaging, derogatory, damaging, and/or critical statements concerning the Company or any subsidiaries or any of their respective affiliates, partners, officers, directors, employees, services, products, and/or activities. 9. Third-Party Agreements and Rights. (a) The Optionee hereby confirms that the Optionee is not bound by the terms of any agreement with any previous employer or other party which restricts in any way the Optionee’s use or disclosure of information or the Optionee’s engagement in any business. In the Optionee’s work for the Company or any of its subsidiaries or Affiliates, the Optionee will not disclose or use any information in violation of any rights of any such previous employer or other party. (b) The Optionee’s employer, if different than the Company, is an intended third-party beneficiary under this Agreement and may enforce the terms of Sections 5, 6, 7, 8, 11, and 12 of this Agreement. This right is subject to (i) the rights of the parties hereto to rescind or vary this Agreement without the consent of any such subsidiary or Affiliate and (ii) the other terms and conditions of this Agreement and the Plan. 10. Transferability. This Agreement is personal to the Optionee, is non-assignable and is not transferable in any manner, by operation of law or otherwise, other than by will or the laws of descent and distribution or as permitted by the Administrator (or its delegee). This Stock Option is exercisable, during the Optionee’s lifetime, only by the Optionee or the Optionee’s legal guardian, if any, and thereafter, only by the Optionee’s legal representative or legatee. Notwithstanding anything to the contrary, to the extent that the Administrator, in its sole discretion, determines that all or any portion of this Stock Option does not qualify as an “incentive stock option” under Section 422 of the Code, whether pursuant to Section 6(b)(viii) of the Plan or otherwise, the Optionee may transfer, without consideration for the transfer, such part of this Stock Option to members of the Optionee’s immediate family, to trusts for the benefit of such family members, or to partnerships in which such family members are the only partners, provided that the transferee (and, as required by the Administrator, the beneficiaries or members of such transferee) agrees in writing with the Company to be bound by all of the terms and conditions of the Plan and this Agreement. Following such a permitted transfer, the provisions of this Agreement providing for the exercise of this Stock Option by the Optionee shall be deemed to permit exercises by a permitted transferee to whom all or a part of this Stock Option has been permissibly transferred. 11. Status of the Stock Option; Certain Tax Matters. (a) While all or a portion of this Stock Option may be intended to qualify as an “incentive stock option” under Section 422 of the Code, the Company does not represent or warrant that this Stock Option qualifies as such, and none of the Company, any of its Affiliates, the Administrator or any person acting on behalf of the Company, any of its Affiliates or the Administrator, will be liable to the Optionee or to the estate or beneficiary of the Optionee or to any person by reason of the failure of the Stock Option to satisfy the requirements of Section 422 of the Code. The Optionee should consult with the Optionee’s own tax advisors regarding the tax effects of this Stock Option and the requirements necessary to obtain favorable income tax treatment under Section 422 of the Code, including, but not limited to, holding period and exercise requirements. The Optionee acknowledges and agrees that the Company or the Administrator may take any action permitted under the Plan without regard to the effect such action may have on the status of the Stock Option as an incentive stock option and that such actions may cause the Stock Option to fail to be treated as an incentive stock option. 13 (b) With respect to any portion of this Stock Option that is intended to qualify as an “incentive stock option” under Section 422 of the Code, if the Optionee intends to dispose or does dispose (whether by sale, gift, transfer, or otherwise) of any shares of Stock underlying this Stock Option within the one-year period beginning on the date after the transfer of such shares to the Optionee, or within the two-year period beginning on the day after the grant of this Stock Option, the Optionee will notify the Company in writing within fifteen (15) days after such disposition. (c) To the extent that the aggregate Fair Market Value (determined at the time of grant) of the Option Shares subject to the portion of the Stock Option, if any, intended to qualify as an incentive stock option, and all other incentive stock options the Optionee holds that are exercisable for the first time during any calendar year (under all plans of the Company and its subsidiaries), exceeds $100,000, the Stock Options held by the Optionee or portions thereof that exceed such limit (according to the order in which they were granted in accordance with the regulations under Section 422 of the Code) shall be treated as Non- Qualified Stock Options. (d) With respect to any portion of this Stock Option that is intended to qualify as an incentive stock option under Section 422 of the Code, this Stock Option shall continue to be treated as an incentive stock option to the extent it is exercised within ninety (90) days from the termination of the Optionee’s Employment. To the extent this Stock Option is exercised after ninety (90) days from the termination of the Optionee’s Employment, such Stock Option shall be treated as a Non- Qualified Stock Option. (e) If at the time this Stock Option is exercised the Company determines that under applicable law and regulations it could be liable for the withholding of any federal, state, or local tax or employee’s social security contributions upon such exercise or with respect to a disposition of any shares of Stock acquired upon such exercise, the Optionee expressly acknowledges and agrees that the Optionee’s rights hereunder, including the right to be issued shares of Stock upon exercise, are subject to the Optionee promptly paying to the Company in cash (or by such other means as may be acceptable to the Administrator in its discretion, including, if the Administrator so determines, by the delivery of previously acquired shares of Stock or Option Shares acquired hereunder or by the withholding of amounts from any payment hereunder) all such taxes, at a rate up to the maximum applicable withholding rate, and employee’s social security contributions, in any case, as determined by the Administrator in its discretion. No shares of Stock will be transferred pursuant to the exercise of this Stock Option unless and until the person exercising this Stock Option has remitted to the Company an amount in cash sufficient to satisfy any federal, state, or local withholding tax and employee’s social security contributions requirements, or has made other arrangements satisfactory to the Company with respect to such taxes and employee’s social security contributions. The Optionee authorizes the Company and its subsidiaries to withhold such amount from any amounts otherwise owed to the Optionee, but nothing in this sentence shall be construed as relieving the Optionee of any liability for satisfying the Optionee’s obligation under the preceding provisions of this Section 11(e). 12. Miscellaneous. (a) This Stock Option is subject to adjustment in accordance with the provisions of Section 7 of the Plan. (b) Notice hereunder shall be given (i) to the Company at its principal place of business, and (ii) to the Optionee at the address on file in the Company’s records, or in either case at such other address as one party may subsequently furnish to the other party in writing. (c) The Optionee hereby acknowledges and agrees to the following: (i) this Stock Option is offered to the Optionee at the complete discretion of the Company; (ii) the Plan, this Stock Option and the Retirement Policy do not form part of any contract of employment (or 14 other provision of services) between the Optionee and the Company or any of its subsidiaries or Affiliates and do not confer upon the Optionee any rights with respect to continuance as an employee (or other service provider) of the Company or any of its subsidiaries or Affiliates; (iii) this Stock Option will not affect any right the Company or any of its subsidiaries or Affiliates may have under any employment agreement with the Optionee or under applicable law to terminate the Employment of the Optionee at any time with or without Cause; (iv) this Stock Option is not part of the Optionee’s base salary or wages and will not be taken into account in determining any other employment-related rights that the Optionee may have, such as any rights the Optionee may have to pension or severance pay; and (v) this Stock Option does not confer on the Optionee any implied right or entitlement to the exercise of any discretion in the Optionee’s favor with respect to any discretionary terms in this Stock Option. (d) The Optionee hereby waives all and any rights to compensation or damages in consequence of the termination of Optionee’s Employment with the Company, or any of its subsidiaries or Affiliates, for any reason whatsoever (whether lawfully or unlawfully) insofar as those rights arise or may arise from the Optionee ceasing to have rights under or be entitled to this Stock Option as a result of such termination or from the loss or diminution in value of such rights or entitlements. In the event of any conflict between the terms of this Section 12(d) and the Optionee’s terms of employment, this Section 12(d) shall take precedence (except as required by applicable legislation). (e) Pursuant to Section 10 of the Plan, the Administrator may at any time amend or cancel any outstanding portion of this Stock Option for any purpose that may at the time be permitted by law, but no such action may be taken that materially and adversely affects the Optionee’s rights under this Agreement without the Optionee’s consent. (f) If the Optionee is resident outside of the United States, to the extent permitted by applicable law, the Optionee hereby consents to the holding, processing and transfer of data relating to the Optionee (including sensitive personal data as defined in the UK Data Protection Act 1998) by: (i) the Company and any of its subsidiaries and Affiliates; (ii) any person providing services to the Company, its subsidiaries or Affiliates (including, but not limited to, any third party broker, registrar, or administrator); and (iii) any trustee appointed by the Company, its subsidiaries or Affiliates, in each case for all purposes relating to the administration or operation of the Plan, including the grant, holding, vesting, or exercise of a Stock Option and the delivery, holding, or sale of Stock and, to the extent permitted by applicable law, this consent includes consent to the transfer of such data to countries outside the European Economic Area even if the country in question does not maintain adequate data protection standards. (g) The provisions of this Agreement and all claims or disputes arising out of or based upon this Agreement or relating to the subject matter hereof or thereof will be governed by and construed in accordance with the domestic substantive laws of the State of Delaware without giving effect to any choice or conflict of laws provision or rule that would cause the application of the domestic substantive laws of any other jurisdiction. Notwithstanding the foregoing or anything to the contrary herein, if the Optionee is a resident of, or employed in, the Commonwealth of Massachusetts for at least 30 days prior to the termination of the Optionee’s Employment with the Company or any of its subsidiaries or Affiliates, Section 5(a) and all claims or disputes arising out of or based upon such section or relating to the subject matter thereof will be governed by and construed in accordance with the domestic substantive laws of the Commonwealth of Massachusetts without giving effect to any choice or conflict of laws provision or rule that would cause the application of the domestic substantive laws of any other jurisdiction. (h) The Optionee hereby acknowledges that the Optionee (i) has read thoroughly this Agreement, including, without limitation, Section 5(a), and if this Stock Option qualifies as a Retirement Eligible Award, the Retirement Policy, (ii) is satisfied that the Optionee 15 understands completely this Agreement, and to the extent applicable, the Retirement Policy, and (iii) and agrees to be bound by the terms and conditions set forth herein and, to the extent applicable, in the Retirement Policy. The Optionee understands that the Optionee has the right to consult an attorney before signing this Agreement.

CLAWBACK POLICY The Compensation Committee (the “Committee”) of the Board of Directors (the “Board”) of Affiliated Managers Group, Inc. (the “Company”) believes that it is appropriate for the Company to adopt this Clawback Policy (the “Policy”) to be applied to the Executive Officers of the Company and adopts this Policy to be effective as of the Effective Date. 1. Definitions For purposes of this Policy, the following definitions shall apply: a) “Company Group” means the Company and each of its Subsidiaries, as applicable. b) “Covered Compensation” means any Incentive-Based Compensation granted, vested or paid to a person who served as an Executive Officer at any time during the performance period for the Incentive-Based Compensation and that was Received (i) on or after October 2, 2023, (ii) after the person became an Executive Officer and (iii) at a time that the Company had a class of securities listed on a national securities exchange or a national securities association. c) “Effective Date” means October 16, 2023. d) “Erroneously Awarded Compensation” means the amount of Covered Compensation granted, vested or paid to a person during the fiscal period when the applicable Financial Reporting Measure relating to such Covered Compensation was attained that exceeds the amount of Covered Compensation that otherwise would have been granted, vested or paid to the person had such amount been determined based on the applicable Restatement, computed without regard to any taxes paid (i.e., on a pre-tax basis). For Covered Compensation based on stock price or total shareholder return, where the amount of Erroneously Awarded Compensation is not subject to mathematical recalculation directly from the information in a Restatement, the Committee will determine the amount of such Covered Compensation that constitutes Erroneously Awarded Compensation, if any, based on a reasonable estimate of the effect of the Restatement on the stock price or total shareholder return upon which the Covered Compensation was granted, vested or paid and the Committee shall maintain documentation of such determination and, to the extent required, provide such documentation to the NYSE. e) “Exchange Act” means the Securities Exchange Act of 1934, as amended. f) “Executive Officer” means each “officer” of the Company as defined under Rule 16a-1(f) under Section 16 of the Exchange Act, which shall be deemed to include any individuals identified by the Company as executive officers pursuant to Item 401(b) of Regulation S-K under the Exchange Act. Both current and former Executive Officers are subject to the Policy in accordance with its terms. g) “Financial Reporting Measure” means (i) any measure that is determined and presented in accordance with the accounting principles used in preparing the Company’s financial statements, and any measures derived wholly or in part from such measures and may consist of GAAP or non-GAAP financial measures (as defined under Regulation G of the Exchange Act and Item 10 of Regulation S-K under the Exchange Act), (ii) stock price or (iii) total shareholder return. Financial Reporting Measures may or may not be filed with the SEC and may be presented outside the Company’s financial statements, such as in Managements’ Discussion and Analysis of Financial Conditions and Result of Operations or in the performance graph required under Item 201(e) of Regulation S-K under the Exchange Act. h) “Home Country” means the Company’s jurisdiction of incorporation. i) “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. j) “Lookback Period” means the three completed fiscal years (plus any transition period of less than nine months that is within or immediately following the three completed fiscal years and that results from a change in the Company’s fiscal year) immediately preceding the date on which the Company is required to prepare a Restatement for a given reporting period, with such date being the earlier of: (i) the date the Board, a committee of the Board, or the officer or officers of the Company authorized to take such action if Board action is not required, concludes, or reasonably should have concluded, that the Company is required to prepare a Restatement, or (ii) the date a court, regulator or other legally authorized body directs the Company to prepare a Restatement. Recovery of any Erroneously Awarded Compensation under the Policy is not dependent on if or when the Restatement is actually filed with the SEC. k) “NYSE” means the New York Stock Exchange. l) “Received”: Incentive-Based Compensation is deemed “Received” in the Company’s fiscal period during which the Financial Reporting Measure specified in or otherwise relating to the Incentive-Based Compensation award is attained, even if the grant, vesting, payment, or Committee action to approve the amount granted or certify the level of achievement of the Incentive-Based Compensation occurs after the end of that period. m) “Restatement” means a required accounting restatement of any Company financial statement due to the material noncompliance of the Company with any financial reporting requirement under the securities laws, including (i) to correct an error in previously issued financial statements that is material to the previously issued financial statements (commonly referred to as a “Big R” restatement) or (ii) to correct an error in previously issued financial statements that is not material to the previously issued financial statements but that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period (commonly referred to as a “little r” restatement). Changes to the Company’s financial statements that do not represent error corrections under the then- current relevant accounting standards will not constitute Restatements. Recovery of any Erroneously Awarded Compensation under the Policy is not dependent on fraud or misconduct by any person in connection with the Restatement. n) “SEC” means the United States Securities and Exchange Commission. o) “Subsidiary” means any domestic or foreign corporation, partnership, association, joint stock company, joint venture, trust or unincorporated organization “affiliated” with the Company, that is, directly or indirectly, through one or more intermediaries, “controlling”, “controlled by” or “under common control with”, the Company. “Control” for this purpose means the possession, direct or indirect, of the power to direct or cause the direction of the management and policies of such person, whether through the ownership of voting securities, contract or otherwise. 2. Recoupment of Erroneously Awarded Compensation In the event of a Restatement, any Erroneously Awarded Compensation Received during the Lookback Period prior to the Restatement (a) that is then-outstanding but has not yet been paid shall be automatically and immediately forfeited and (b) that has been paid to any person shall be subject to reasonably prompt repayment to the Company Group in accordance with Section 3 of this Policy. The Committee must pursue (and shall not have the discretion to waive) the forfeiture and/or repayment of such Erroneously Awarded Compensation in accordance with Section 3 of this Policy, except as provided below. Notwithstanding the foregoing, the Committee (or, if the Committee is not a committee of the Board responsible for the Company’s executive compensation decisions and composed entirely of independent directors, a majority of the independent directors serving on the Board) may determine not to pursue the forfeiture and/or recovery of Erroneously Awarded Compensation from any person if the Committee determines that such forfeiture and/or recovery would be impracticable due to any of the following circumstances: (i) the direct expense paid to a third party (for example, reasonable legal expenses and consulting fees) to assist in enforcing the Policy would exceed the amount to be recovered (following reasonable attempts by the Company Group to recover such Erroneously Awarded Compensation, the documentation of such attempts, and, to the extent required, the provision of such documentation to the NYSE), (ii) pursuing such recovery would violate the Company’s Home Country laws adopted prior to November 28, 2022 (provided that the Company obtains an opinion of Home Country counsel acceptable to the NYSE that recovery would result in such a violation and, to the extent required, provides such opinion to the NYSE), or (iii) recovery would likely cause any otherwise tax-qualified retirement plan, under which benefits are broadly available to employees of Company Group, to fail to meet the requirements of 26 U.S.C. 401(a)(13) or 26 U.S.C. 411(a) and regulations thereunder. 3. Means of Repayment In the event that the Committee determines that any person shall repay any Erroneously Awarded Compensation, the Committee shall provide written notice to such person by email or certified mail to the physical address on file with the Company Group for such person, and the person shall satisfy such repayment in a manner and on such terms as required by the Committee, and the Company Group shall be entitled to set off the repayment amount against any amount owed to the person by the Company Group and/or by requiring the forfeiture of any award granted by the Company Group to the person, or to take any and all necessary actions to reasonably promptly recoup the repayment amount from the person, in each case, to the fullest extent permitted under applicable law, including without limitation, Section 409A of the Internal Revenue Code and the regulations and guidance thereunder. 4. No Indemnification No person shall be indemnified, insured or reimbursed by the Company Group in respect of any loss of compensation by such person in accordance with this Policy, nor shall any person receive any advancement of expenses for disputes related to any loss of compensation by such person in accordance with this Policy, and no person shall be paid or reimbursed by the Company Group for any premiums paid by such person for any third-party insurance policy covering potential recovery obligations under this Policy. For this purpose, “indemnification” includes any modification to current compensation arrangements or other means that would amount to de facto indemnification (for example, providing the person a new cash award which would be cancelled to effect the recovery of any Erroneously Awarded Compensation). 5. Miscellaneous This Policy generally will be administered and interpreted by the Committee, provided that the Board may, from time to time, exercise discretion to administer and interpret this Policy, in which case, all references herein to “Committee” shall be deemed to refer to the Board. Any determination by the Committee with respect to this Policy shall be final, conclusive and binding on all interested parties. Any discretionary determinations of the Committee under this Policy, if any, need not be uniform with respect to all persons, and may be made selectively amongst persons, whether or not such persons are similarly situated. This Policy is intended to satisfy the requirements of Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, as it may be amended from time to time, and any related rules or regulations promulgated by the SEC or the NYSE, including any additional or new requirements that become effective after the Effective Date which upon effectiveness shall be deemed to automatically amend this Policy to the extent necessary to comply with such additional or new requirements. The provisions in this Policy are intended to be applied to the fullest extent of the law. To the extent that any provision of this Policy is found to be unenforceable or invalid under any applicable law, such provision will be applied to the maximum extent permitted and shall automatically be deemed amended in a manner consistent with its objectives to the extent necessary to conform to applicable law. The invalidity or unenforceability of any provision of this Policy shall not affect the validity or enforceability of any other provision of this Policy. Recoupment of Erroneously Awarded Compensation under this Policy is not dependent upon the Company Group satisfying any conditions in this Policy, including any requirements to provide applicable documentation to the NYSE. The rights of the Company Group under this Policy to seek forfeiture or reimbursement are in addition to, and not in lieu of, any rights of recoupment, or remedies or rights other than recoupment, that may be available to the Company Group pursuant to the terms of any law, government regulation or stock exchange listing requirement or any other policy, code of conduct, employee handbook, employment agreement, equity award agreement, or other plan or agreement of the Company Group. This Policy does not broaden any rights or obligations of any non-wholly owned Subsidiary that are not otherwise applicable to such Subsidiary. 6. Amendment and Termination To the extent permitted by, and in a manner consistent with applicable law, including SEC and NYSE rules, the Committee may terminate, suspend or amend this Policy at any time in its discretion. 7. Successors This Policy shall be binding and enforceable against all persons and their respective beneficiaries, heirs, executors, administrators or other legal representatives with respect to any Covered Compensation granted, vested or paid to or administered by such persons or entities.
