PART I
Item 1. Business.
Overview
We are a holding company that operates a systematic investment management business through our majority owned subsidiary, Acadian Asset Management LLC (“Acadian LLC”). With approximately $178 billion of assets under management as of December 31, 2025, Acadian LLC offers institutional investors across the globe access to a diversified array of systematic investment strategies designed to meet a range of risk and return objectives. The ownership structure of Acadian LLC provides incentives for growth and prudent business management across multiple generations of Acadian LLC partners, who retain meaningful levels of equity in their own business to preserve strong alignment of interests between us, Acadian LLC, their clients, and our stockholders. Our profit-sharing model enables us to participate directly in margin expansion as Acadian LLC grows. Acadian LLC comprises our Quant & Solutions reportable segment.
Acadian LLC
Acadian LLC, founded in 1986, is a leading systematic investment manager with approximately $178 billion in AUM as of December 31, 2025. Acadian LLC pursues a fundamentally grounded, data-rich, and highly structured approach to investing that seeks to identify and exploit systematic and structural inefficiencies in the markets. Acadian LLC applies a range of investment and risk considerations to a universe of 65,000-plus securities taken from over 150 global markets. Acadian LLC manages strategies in developed and developing markets. Notable product lines and capabilities include Emerging Equity, Non-U.S. Equity, Global Equity, Small Cap Equity, Enhanced Equity, Equity Extensions, Systematic Credit, and Alternatives.
Acadian LLC predominantly invests on behalf of a wide range of institutional clients across the globe, including public and private funds, endowments and foundations. The firm’s clients were domiciled in more than 40 countries across the globe as of December 31, 2025. The firm has over 100 investment and research professionals and manages numerous investment products and strategies.
Competitive Strengths
Experience. As a pioneer in systematic investing, we have been managing systematic equity portfolios since the 1980s. This experience affords us a broad perspective and data history. Guided by the economic intuition and insights of a talented, experienced, and diverse investment team, we have been at the forefront of systematic research, signal development, and portfolio construction for nearly 40 years.
Objectivity. We use a disciplined and objective process, underpinned by rich data and powerful technological tools. An extensive data repository, continually supplemented by an active alternative scouting effort, provides an extensive source for exploring new investment ideas. Given the size, breadth, and complexity of global markets, we believe that such an empirical approach is essential to exploiting behaviorally based mispricings and delivering superior risk-adjusted returns for our clients.
Research. We are a research-focused firm. Our scientific approach to innovation is driven by research across signal generation, portfolio construction, implementation, and risk management. Research is data-dependent, and our process benefits from its objectivity, breadth, and computational power. We recognize that markets are dynamic and that a robust culture of investment research is essential to maintaining a competitive edge.

Capital Management
Our business generates significant, recurring free cash flow that can be used to return capital to stockholders through share repurchases and dividends, repay outstanding debt, and more broadly create value for our stockholders. In particular, we believe we can generate strong returns on allocated capital by, among other things, (i) providing seed capital to fund new products and strategies; (ii) providing investment capital to support strategic growth initiatives; and (iii) implementing opportunistic share repurchases. Management undertakes detailed business case analyses with respect to all growth opportunities, and only considers those that yield an acceptable return while operating within the parameters of our risk appetite. For the period January 1, 2020 to December 31, 2025, we repurchased approximately 58% of our shares.
Distribution and Client Base
Our distribution is focused on the institutional, sub-advisory, and wealth/other channels. The institutional channel accounts for over 80% of our AUM. Within this channel, we have strong relationships in the public/government pension market and the corporate plan market, which comprise a substantial portion of the institutional investment market overall, particularly in the U.S. Our institutional marketplace clients are highly diverse across industry segments and geographies and have various growth characteristics. Our institutional clients are from across the globe, including, but not limited to, pension funds, state and local governments; sovereign wealth funds, employee benefit plans and foundations and endowments. We offer our investment products to institutional clients directly and by marketing our services to the investment consultants and advisors that advise them. We maintain relationships with a number of insurance companies, private banks, Outsourced Chief Investment Officers (“OCIOs”) and Fund of Funds (“FoFs”). While we market primarily to institutional investors, we also participate in the individual investor market via the sub-advisory and wealth/other channels, which together represent almost 20% of our AUM. Clients within these channels include registered investment advisors, private banks, high net-worth clients, family offices, and defined contribution clients on certain platforms.
Our clients can access our investment strategies through a range of investment vehicles:
•Separate Account: We manage separate account assets within most of our investment strategies. Our separate account clients span the broad spectrum of institutional investors. The fees we charge on separate accounts vary by client, investment strategy and the size of the account.
•Funds: We also offer access to our strategies through commingled funds both within and outside the U.S. Investors that do not meet our minimum account size for a separate account, or who otherwise prefer to invest through a fund, can invest in our pooled funds.
The goal of our marketing, distribution and client service efforts is to grow and maintain a diversified client base. We focus our distribution and marketing efforts on sophisticated investors and asset allocators. Our client service and distribution teams comprise knowledgeable, seasoned professionals, experienced in working across the investment spectrum of investors.
Our client base is diverse without significant concentration. As of December 31, 2025, our top five client relationships represented approximately 14% of total run rate gross management fee revenue, and our top 25 clients represented approximately 33% of run rate gross management fee revenue. The below graphic shows the breakdown of our assets under management as of December 31, 2025 by client type and client location.

Products and Investment Performance
Product Mix
We offer leading strategies in developed and developing markets.
The chart below presents our wide range of offerings. These offerings are designed to provide a balanced earnings stream to our business. We believe our offerings are well-positioned in areas of investor demand and the diversity of investment style and asset class can enable us to participate in growing segments of the industry, through a range of investing environments.
Our notable product lines and capabilities include Emerging Equity, Non-U.S. Equity, Global Equity, Small Cap Equity, Enhanced Equity, Equity Extensions, Systematic Credit, and Alternatives. Enhanced strategies offer attractive risk-adjusted returns with comparatively lower active risk relative to standard active offerings. Extension portfolios are a form of high conviction investing which leverage both long and short positions to increase active views, such as 130/30 products.

Investment Performance
Our mission is to produce strong risk-adjusted returns for our clients. We have competitive near- and long-term track records and are well-positioned for continued growth.
In addition to analyzing our performance on a revenue-weighted basis, which gives us a perspective on product performance with respect to our existing client base, we also consider the number of our at-scale product strategies (defined as strategies with greater than $100 million of AUM) beating benchmarks. This latter measure, labeled as “equal-weighted,” indicates the opportunity we have to generate sales in a variety of market environments. For instance, strong performance in a newer, smaller product may not affect revenue-weighted performance, but it can have a meaningful effect on revenue growth given client demand for this higher fee product. We also present our performance by showing the percentage of our assets beating their benchmarks over the same time periods.
The charts below reflect performance versus benchmark on a revenue-weighted basis on a trailing three-, five-, and ten-year basis over each of the last five years. Performance figures for all periods are calculated using gross of fee strategy composite returns. Our long-term performance has been strong since 2021. Past performance is no guarantee of future results. This is not investment advice and may not be construed as sales or marketing material for any financial product or service sponsored or provided by Acadian LLC.
Data as of December 31 for the years 2021 to 2025
*Assets representing 89%, 88%, 80%, 91% and 57% of revenue were outperforming benchmarks on a 1- year basis as of December 31, 2021, 2022, 2023, 2024 and 2025, respectively.

Competition
The industry in which we operate is highly competitive. In order to be successful and grow our business, we must be able to compete effectively for AUM. We compete globally with international and domestic investment management firms, hedge funds, and other subsidiaries of financial institutions for institutional assets.
Many of the organizations we compete with offer investment strategies similar to those offered by us, and these organizations may have greater financial resources and distribution capabilities than we offer. Some of these firms offer other products and services—in particular investment strategies such as passively managed products, including exchange traded funds, that typically carry lower fee rates. Additionally, there are limited barriers to entry for new investment managers. We compete with these organizations to attract and retain institutional clients and their assets based on the following primary factors:
•the investment performance records of our strategies;
•the breadth of active investment strategies and vehicle options that we offer;
•the alignment of our investment strategies to the current market conditions and investment preferences and needs of potential clients;
•the quality, depth, and reputation of the investment teams that execute our strategies;
•the continuity of our investment and distribution teams;
•the caliber of service we provide our clients; and
•our brand recognition and reputation within the investment community
Our History and Organizational Structure
The predecessor of AAMI was formed in 1980. We were incorporated on May 29, 2014 as a private limited company under the laws of England and Wales and completed a redomestication process to become a Delaware corporation on July 15, 2019. Effective as of January 1, 2025, we changed our name from BrightSphere Investment Group Inc. to Acadian Asset Management Inc.

Regulation
We are subject to U.S. federal securities laws, state securities and corporate laws, and the rules and regulations of U.S. regulatory and self-regulatory organizations.
Acadian LLC (including its subsidiaries) is also subject to regulation in the U.S. through its primary regulator, the SEC, under the Investment Advisers Act of 1940, as amended. To the extent Acadian LLC acts as investment adviser or sub-adviser to registered investment companies, it must also comply with the terms of the Investment Company Act of 1940, as amended and the rules thereunder. The Advisers Act of 1940 imposes numerous obligations on registered investment advisers, including fiduciary, record keeping, advertising and operational requirements, disclosure obligations, and prohibitions on fraudulent activities. The Investment Company Act of 1940 regulates the structure and operations of registered investment companies and imposes additional obligations on advisers to registered investment companies, including detailed disclosure and regulatory requirements applicable to the registered investment companies and additional compliance responsibilities which must strictly be adhered to by the funds and their advisers. Acadian LLC is also subject to the rules and regulations adopted by the Commodity Futures Trading Commission, under the Commodity Exchange Act; and may also be subject to the rules and regulations adopted by the Department of Labor, under ERISA; the Financial Industry Regulatory Authority, Inc., or FINRA; and state regulators. Acadian LLC and its subsidiaries may also be registered from time to time in jurisdictions outside of the U.S. and will be subject to applicable regulation in those jurisdictions. Acadian LLC is also subject to regulation relating to the offer and sale of financial products in each of the European Union countries in which Acadian LLC and its subsidiaries operate. As we expand distribution efforts into non-U.S. jurisdictions, including other member countries of the European Union, Latin America, the Middle East and Asian countries, we may be required to register with additional foreign regulatory authorities or otherwise comply with non-U.S. rules and regulations that currently are not applicable to our business.
Through wholly owned subsidiaries, Acadian LLC is also subject to the regulatory environments of the non-U.S. jurisdictions in which Acadian LLC operates. Acadian LLC’s U.K. subsidiary is subject to regulation by the Financial Conduct Authority, or FCA. Acadian LLC’s Singapore subsidiary is subject to regulation by the Monetary Authority of Singapore. Acadian LLC Australia is subject to regulation by the Australian Securities and Investment Commission. Each regulatory body imposes a comprehensive system of regulation on investment advisers and the manner in which we conduct our business in that country.
Employees and Human Capital
We believe our ability to attract and retain employees is a key to our success. Accordingly, we strive to offer competitive compensation and employee benefits and monitor compensation and benefits to the competitive market. Our total rewards philosophy includes competitive compensation, talent development and a comprehensive benefits package that includes extensive health and welfare benefits. In addition, we provide a Profit Sharing and 401(k) Plan for all employees and contribute a percentage of compensation to this plan on a discretionary basis, subject to regulatory limits.
We recognize the value of a diverse and skilled workforce and are committed to creating and maintaining an inclusive and collaborative workplace culture that leverages the unique contributions of people with diverse backgrounds, experiences, and perspectives. We are committed to pay equity for employees doing similar work, regardless of gender, race or ethnicity and comply with applicable local regulations.
As of December 31, 2025, we had 396 full-time equivalent employees, of which 20 are at Hold Co. None of these employees are represented by any collective bargaining agreements.
10
Operations and Technology
Our advanced technological capabilities are one of our core strengths. Our investment process is systematically driven and is supported by a sophisticated systems environment, including the use of artificial intelligence. A key tenet of our investment philosophy is that it is crucial to examine as much relevant information about as many companies as possible. Our systems allow us to evaluate a broad array of investment opportunities on a daily basis. Important aspects of our systems environment include powerful servers that receive fundamental data on a continuous basis; proprietary software that transforms the data into stock-specific, macro, and peer forecasts; portfolio optimization software that assists in the creation of customized client portfolios; and a fully automated trading and compliance system. Beyond the investment process infrastructure, we use a number of sophisticated systems to help maximize back-office efficiencies across functions such as operations, accounting, and client reporting.

Item 1A. Risk Factors
You should carefully consider the following risk factors in addition to the other information included or incorporated by reference in this Annual Report on Form 10-K before investing in our common stock. Any of the following risks could have a material adverse effect on our business, financial condition, results of operations or cash flow. If any of the following risks and uncertainties actually occurs, you may lose all or part of your investment. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also adversely affect our business.
Risks Related to Operations
Our overall financial results are dependent on the ability of Acadian LLC to generate earnings.
Substantially all of our revenue generation is dependent on Acadian LLC, which receives the majority of its fees based on the values of assets under management. Substantially all of our cash flows consist of distributions received from Acadian LLC. As a result, our cash flows and ability to fund operations are largely dependent upon the profitability of Acadian LLC.
Acadian LLC is required to make certain cash distributions to us under its operating agreement. Distributions to us from Acadian LLC may be subject to Acadian LLC maintaining sufficient working capital, regulatory requirements, claims of creditors of Acadian LLC and applicable bankruptcy and insolvency laws. Any material decrease in profits at, or material reduction in distributions from, Acadian LLC could negatively impact our business and results of operations.
Acadian LLC operates under ownership, governance and economic arrangements that we and Acadian LLC negotiated either at inception or during the course of our relationship. Any renegotiation of the economic arrangement could reduce the economic benefits derived by us from Acadian LLC.
Our ability to attract and retain assets under management and generate earnings is dependent on maintaining competitive investment performance, as well as market, economic and other factors.
Our financial performance is dependent upon our ability to minimize outflows and increase inflows through sound relative investment performance over measured periods of time compared to relevant benchmarks and peer performance results. The performance of our investment strategies, which can be impacted by factors within and/or outside our control, including general market and economic conditions, is critical to retaining existing client assets and investors, including in funds we advise or sub-advise, and attracting new client and investor assets. Poor performance can be caused by our choices in investing in sectors, industries, companies or assets that do not perform as well as others. Additionally, companies in which we invest may incur negative changes in their financial conditions or suffer other adverse events that could reduce the values of investments in those companies.
Net flows related to our investment strategies can be affected by investment performance relative to other competing investment strategies or to established benchmarks. Investment management strategies may be rated, ranked or assessed by independent third parties, distribution partners, and industry periodicals and services. These assessments often influence the investment decisions of our clients and investors in funds we advise or sub-advise. If the performance or assessment of our investment strategies is seen as underperforming relative to peers, it could, among other things, result in an increase in the withdrawal of assets by existing clients and investors and the inability to attract additional investments. If a significant portion of clients or investors decides to withdraw their investments or terminate their investment management agreements or sub-advisory agreements, our ability to generate earnings would decline and our results of operations and financial condition would be affected.
In addition, assets could be withdrawn for any number of reasons other than poor absolute or relative investment performance, including macro-economic factors unrelated to investment performance, a reduction in market demand
12
for the asset classes, products or strategies we offer, the loss of key personnel, price declines in the securities markets generally, price declines in those assets in which client assets are concentrated or changes in investment patterns of clients, a failure by us to comply with applicable client and regulatory investment guidelines, or factors wholly unrelated to us.
Our investment strategies are materially affected by market and economic conditions throughout the world, including conditions relating to interest rates, availability of credit, inflation rates, economic uncertainty and growth (or contraction), changes in laws (including laws relating to taxation), trade barriers, commodity prices, currency exchange rates, and liquidity conditions in equity and debt capital markets. Although decelerating, inflation remains above the U.S. Federal Reserve’s target levels. Despite multiple federal fund rate decreases since 2024, interest rates remain elevated, and the pace of future rate decreases remains uncertain. Periods of elevated inflation and high interest rates can contribute to significant volatility in debt and equity markets and economic deceleration, which may adversely impact the value of our clients' investments and our ability to attract and retain assets under management. Any of these factors could have a negative impact on our results of operations and financial conditions.
We derive a substantial portion of our revenue from a limited number of investment strategies.
A significant portion of our assets are invested in a limited number of investment strategies. As of December 31, 2025, $81 billion, or 46%, of our assets under management were concentrated across five investment strategies: Acadian Emerging Markets Equity ($21 billion, or 12%) Acadian Enhanced Global Equity ($18 billion, or 10%), Acadian All-Country World ex-U.S. Equity ($17 billion, or 10%), Acadian Non-U.S. Small-Cap Equity ($14 billion, or 8%), and Acadian Non-U.S. Equity ($12 billion, or 6%). Consequently, our results of operations are dependent upon our ability to minimize the risk of outflows from these strategies through relatively strong performance over measured periods of time compared to relevant benchmarks and peer performance results. Also, certain investors may evaluate us on the basis of the asset-weighted performance of our assets under management. A relatively small change in the relative performance of one of our largest strategies, such as Acadian Emerging Markets Equity, could have a significant impact on the asset-weighted performance of our assets under management. Such volatility could adversely affect our results of operations and investors’ perception of us.
Investments in non-U.S. markets, in securities of non-U.S. companies and utilization of currency forward contracts and options on currency may involve foreign currency exchange risk, and tax, political, social and economic uncertainties, and a reduction in assets under management associated with investments in non-U.S. equities could have a disproportionately adverse impact on our results of operations.
A significant amount of our assets under management is represented by strategies that invest in securities of non-U.S. companies. As of December 31, 2025, approximately 70% of our AUM is in non-US denominated currencies. Fluctuations in foreign currency exchange rates could negatively impact the account values and the investment returns of clients who are invested in these strategies, with a corresponding reduction in management fee income. In addition, an increase in the value of the U.S. dollar relative to non-U.S. currencies could result in a decrease in the U.S. dollar value of assets under management that are denominated in non-U.S. currencies, which in turn would result in lower revenues.
Many non-U.S. financial markets are not as developed or as efficient as the U.S. financial markets and, as a result, have limited liquidity and greater price volatility and may lack established regulations. Liquidity in such markets also may be adversely impacted by political or economic events, government policies, expropriation, volume trading limits by foreign investors, and social or civil unrest. The ability to dispose of an investment and its market value may be adversely impacted by any of these factors. In addition, non-U.S. legal and regulatory financial accounting standards and practices may be different from those of the U.S., and there may be less publicly available information about non-U.S. companies and non-U.S. markets. Governments of foreign jurisdictions may assert their abilities to tax local gains and/or income of foreign investors, including our clients, which could adversely impact the economics associated with investing in foreign jurisdictions or non-U.S. based companies. These risks also could impact the performance of strategies that invest in such markets and, in particular, strategies that concentrate investments in emerging market companies and countries.

We rely on certain key personnel, and our results are dependent upon our ability to retain and attract key personnel.
We depend on the skills and expertise of our key investment and management personnel, and our success and growth depends on our ability to attract and retain key personnel. We rely heavily upon the services of certain key investment and management personnel. The loss of key investment and management personnel for any reason could have an adverse impact upon our business, results of operations and financial condition. Any of our key investment or management personnel could resign at any time, join a competitor or form a competing company. We have entered into non-competition agreements with some, but not all, of our investment and management personnel, but these agreements may not be enforceable or may not be enforceable to their full extent. Additionally, key employees receive equity awards that limit a recipient’s right to provide competitive services to our clients or solicit our employees for prescribed periods. However, we may agree to waive restrictive covenants applicable to investment or management personnel in light of the circumstances of our relationship with that person.
We rely upon the contributions of our senior management team to establish and implement our strategy and to manage the future growth of our business. The amount and structure of compensation and opportunities for equity ownership we offer are key components of our ability to attract and retain qualified management personnel. There is no assurance that we will be successful in designing and implementing an attractive compensation model to attract and retain qualified personnel.
Our business operations are complex, and a failure to properly perform operational tasks or maintain infrastructure could have an adverse effect on our revenues and income.
In addition to providing investment management services, we must have the necessary operational capabilities to manage our business effectively in accordance with client expectations and applicable law. The required non-investment management functions include sales, marketing, portfolio recordkeeping and accounting, security pricing, trading activity, investor reporting, corporate governance, compliance, net asset value computations, account reconciliations and calculations of required distributions to accounts. Some of these functions are performed either independently or with the support of or in conjunction with us or third-party service providers that we oversee. Also, we may be highly dependent on specially developed proprietary systems, including proprietary computer code. Any material failure to properly develop, update, review, test or maintain sufficient technological infrastructure, including applicable controls, or perform and monitor non-investment management functions and operations, or adequately oversee the entities that provide the services, could result in potential liability to clients, regulatory sanctions, investment losses, loss of clients and damage to our reputation. Our or our third-party service providers’ use of artificial intelligence (“AI”) technologies could result in new and expanded risks, particularly as the use of AI applications increases in prevalence and scope. Our failure to effectively manage the development and use of AI, our competitors' development or use of AI, and an evolving AI regulatory environment could have an adverse effect on our growth prospects, reputation, or business and results of operations.
Reputational harm could result in a loss of assets under management and revenues.
The integrity of our brand and reputation is critical to our ability to attract and retain clients, business partners and employees and maintain relationships with consultants. We operate within the highly regulated financial services industry and various potential scenarios could result in harm to our reputation. They include internal operational failures, failure to follow investment or legal guidelines in the management of accounts, instances of financial criminal activity by our employees, intentional or unintentional misrepresentation of our products and services in offering or advertising materials, public relations information, social media or other external communications, employee misconduct or investments in businesses or industries that are controversial to certain special interest groups. Such factors could potentially result in regulatory actions and litigation. The negative publicity associated with any of these factors could harm our reputation and adversely impact relationships with existing and potential clients, third-party distributors, consultants and other business partners and subject us to regulatory sanctions. Damage to our brand or reputation would negatively impact our standing in the industry and result in loss of business in both the short term and the long term.
14
We may not always successfully manage actual or potential conflicts of interests that may arise in our business.
As we continue to expand the scope of our business, we continue to confront actual, potential and perceived conflicts of interest relating to our activities. Conflicts may arise with respect to decisions regarding, among other things, the allocation of specific investment opportunities among accounts in which we may receive an allocation of profits and accounts in which we do not receive such an allocation or among client accounts that have overlapping investment objectives yet different fee structures, including certain accounts which may pay performance-based fees.
Certain client accounts have similar investment objectives and may engage in transactions in the same types of securities and instruments. These transactions could impact the prices and availability of the securities and instruments in which a client account invests and could have an adverse impact on an account’s performance.
The SEC and other regulators have increased their scrutiny of conflicts of interest. We have implemented procedures and controls to identify, manage, mitigate (where possible) and disclose actual, potential or perceived conflicts of interest, but it is possible that the procedures adopted may not be effective in identifying, managing or mitigating all conflicts which could give rise to the dissatisfaction of, or litigation by, investors or regulatory enforcement actions. Appropriately dealing with conflicts of interest is complex and difficult, and our reputation could be damaged if we fail, or appear to fail, to deal appropriately with one or more potential or actual conflicts of interest. Regulatory scrutiny, litigation or reputational risk incurred in connection with conflicts of interest would adversely impact our business in a number of ways, including by making counterparties reluctant to do business with us, impeding our ability to retain or increase our assets under management, subjecting us to potential litigation and adversely impacting our results of operations.
Equity ownership by our employees may be at Acadian LLC or at the holding company level. There may be instances where the interests of equity-holders of Acadian LLC may not align with our stockholders in effecting a desired outcome.
There is no assurance that a resolution of any conflicts of interest may be possible or the interests of all parties can be taken into account.
Impairment of our relationships with clients and/or consultants may negatively impact our business and our results of operations.
We believe we have strong client and consultant relationships in our core institutional marketplaces, and we depend upon these relationships to successfully market our existing products and strategies and to introduce new products and strategies. As of December 31, 2025, our top five client relationships represented approximately 14% of total run rate gross management fee revenue, and our top 25 clients represented approximately 33% of run rate gross management fee revenue. Total run rate gross management fee revenue reflects the sum for each account at Acadian LLC, of the product of (a) assets under management in each account at December 31, 2025, multiplied by (b) the relevant management fee rate on that account. Any negative changes in these relationships that reduce the number of client or consultant contacts, restrict access to existing or potential clients, or result in negative statements by a consultant, could have an adverse impact on ourbusiness and negatively impact our results of operations.
Our business is dependent upon investment advisory agreements that are subject to negotiation, non-renewal, or termination, including termination upon assignment.
We derive substantially all of our revenue from the fees charged to our clients under investment advisory agreements with those clients. The agreements generally provide for fees to be paid on the basis of the value of assets under management, although a portion also provide for performance-based fees to be paid on the basis of investment performance against stated benchmarks.
15
Acadian LLC is a U.S. registered investment adviser. Acadian LLC may provide investment advisory services to investment companies registered under the Investment Company Act pursuant to the terms of an investment advisory agreement between Acadian LLC and the applicable U.S. registered investment company. Acadian LLC may also be retained by U.S. registered investment advisers to certain U.S. registered investment companies to provide investment sub-advisory services to U.S. registered investment companies pursuant to the terms of an investment sub-advisory agreement between Acadian LLC and the relevant U.S. registered investment adviser. An investment advisory agreement may be terminated by a client without penalty upon relatively short notice (typically no more than 30 days). In addition, the investment advisory agreements and sub-advisory agreements with respect to registered investment companies generally may be terminated by the registered investment company or, in those instances where Acadian LLC serves as a sub-adviser, the registered investment company’s adviser, without penalty, upon 60 days’ notice and are subject to annual approval by the registered investment company’s board of directors or trustees. Clients may decide to terminate or not renew an agreement for poor investment performance or any variety of reasons which may be beyond our control. A decrease in revenues resulting from termination of an investment advisory agreement or sub-advisory agreement for any reason could have a material adverse effect on our revenue and profits and a negative effect on our results of operations.
Pursuant to the Advisers Act, investment advisory agreements between Acadian LLC, which is a U.S. registered investment advisers and its clients are not assignable without the consent of the client. As required by the Investment Company Act of 1940, (the “Investment Company Act”), investment advisory agreements and sub-advisory agreements between Acadian LLC and investment company clients and/or the investment advisers to those investment companies terminate upon their assignment. Assignment, as generally defined, includes direct assignments as well as assignments that may be deemed to occur, under certain circumstances, upon the direct or indirect transfer of a “controlling block” of the voting securities of Acadian LLC. A transaction is not deemed an assignment under the Advisers Act or the Investment Company Act, however, if it does not result in a change of actual control or management of Acadian LLC.
If anyone acquires, or is deemed to have acquired, a controlling block of our voting securities in the future, the contractual anti-assignment and termination provisions of the investment advisory and sub-advisory agreements between Acadian LLC and its clients may be implicated. If an assignment of an investment advisory or sub-advisory agreement is deemed to occur, and clients do not consent to the assignment or, with respect to investment company clients, enter into a new agreement with Acadian LLC, which may require the approval of the investment company’s stockholders in addition to its board of directors or trustees, our results of operations could be materially and adversely affected.
Pressure on fee levels and changes to mix of assets could impact our results of operations.
Our profit margins and net income are dependent on our ability to maintain current fee levels for the products and services we offer. The competitive nature of the asset management industry has led to a trend toward lower fees in certain segments of the asset management market, and there can be no assurance that we will be able to maintain our current pricing structures. We also may be required to restructure our fees due to regulatory changes. These factors also could inhibit the ability to increase fees for certain products. A reduction in the fees, or limited opportunities to increase fees, will reduce or limit our revenues and could reduce or limit our net income.
The fees charged on our assets under management vary by asset class and produce different revenues per dollar of assets under management based on factors such as the type of assets being managed, the applicable investment strategy, the type of client and the client fee schedule. Institutional clients may have significant negotiating leverage in establishing the terms of an advisory relationship, particularly with respect to the level of fees paid, and the competitive pressure to attract and retain institutional clients may impact the level of fee income we earn. In order for us to maintain our fee structure in a competitive environment, we may elect to decline to manage additional assets from potential clients who demand lower fees even though our revenues may be adversely affected in the short term.
16
Furthermore, a shift in the mix of assets under management from asset classes or products that generate higher fees to those that generate lower fees may result in a decrease in revenues while aggregate assets under management remain unchanged or increase. Such shifts can occur as various investment strategies go in and out of favor due to competition in the industry or as a result of movements between asset classes or certain products no longer being available to investors. In addition, in the event Acadian LLC has or develops a focus on strategies that generate lower fees, a decrease in revenues may result. A decrease in revenues without a reduction in expenses will result in reduced net income.
Changes in how clients choose to access asset management services may also exert downward pressure on fees. Some investment consultants, for example, are implementing programs in which the consultant provides a range of services, including selection, in a fiduciary capacity, of asset managers to serve as sub-adviser at lower fee rates than the manager’s otherwise applicable rates, with the expectation of a larger amount of assets under management through that consultant. The expansion of those and similar programs could, over time, make it more difficult for us to maintain our fee rates.
If our techniques for managing risk are ineffective, we may be exposed to material unanticipated losses.
In order to manage the significant risks inherent in our business, we must maintain effective policies, procedures and systems that enable us to identify, monitor and control our exposure to operational, legal and reputational risks. Our risk management methods may prove to be ineffective due to their design or implementation, or as a result of the lack of adequate, accurate or timely information or otherwise. If our risk management efforts are ineffective, we could suffer losses that could have a material adverse effect on our financial condition or results of operations. The potential for some types of operational risks, including, for example, trading errors, may be increased or amplified in periods of increased volatility, which can magnify the cost of an error. We may experience operational errors, including trading errors, in the future. Additionally, we could be subject to litigation, particularly from our clients, and investigations and enforcement proceedings by and sanctions or fines from regulators. Ourtechniques for managing operational, legal and reputational risks in client portfolios may not fully mitigate the risk exposure in all economic or market environments, including exposure to risks that we might fail to identify or anticipate.
In addition, the development and use of various technologies based on machine learning and AI is expanding rapidly in our industry. Our use, directly or indirectly, of these technologies could result in new or expanded risks to our business, including but not limited to legal and regulatory risk and the risk that information generated using such technologies is inaccurate, misleading, incomplete or otherwise flawed. To the extent that we do not anticipate or effectively mitigate these risks through policies, controls and procedures, and systems, there could be a material adverse effect on our financial condition and results of operations.
17
We may be exposed to potential liability as a general partner or a controlling person.
Acadian LLC may serve as general partner, managing member or their equivalents for investment products that are organized as partnerships or other commingled vehicles. As such, we may be exposed to liability in the limited liability company, partnership or investment vehicle or required to undertake certain obligations under applicable law that we or they otherwise would not be required to undertake as a holding company or investment adviser. In addition, we may be deemed to be a control person of Acadian LLC as that term is defined in various U.S. federal and state statutes and, as such, potentially liable for the acts of Acadian LLC or its employees. Consequently, if under such circumstances Acadian LLC incurs liabilities or expenses that exceed its ability to pay, we may be directly or indirectly liable for its payment to the extent provided in the governing documents of the limited liability company, partnership or investment vehicle or under applicable law. While we maintain errors and omissions and general liability insurance in amounts believed to be adequate to cover certain potential liabilities, we cannot be certain that claims will not be made against us that exceed the limits of available insurance coverage, that the insurers will remain solvent and will meet their obligations to provide coverage or that an adequate amount of insurance coverage will continue to be available to us at a reasonable cost. A judgment against us in excess of available insurance coverage could have a material adverse impact on our business and financial condition.
Our expenses are subject to fluctuations that could materially impact our results of operations.
Our results of operations are dependent upon the level of our expenses, which can vary from period to period. We have certain fixed expenses that we incur as a going concern, and some of those expenses are not subject to adjustment. If our revenues decrease, without a corresponding decrease in expenses, our results of operations would be negatively impacted. While we attempt to project expense levels in advance, there is no guarantee that an unforeseen expense will not arise or that we will be able to adjust our variable expenses quickly enough to match a declining asset base. Consequently, either event could have either a temporary or permanent negative impact on our results of operations.
Losses on our seed capital could adversely impact our results of operations or financial condition.
As of December 31, 2025, we had approximately $90 million committed to seed capital, which is currently invested in seven products. The amount we commit to, or invest in, seed capital could change materially from time to time in our discretion based on the needs of the business. The capital utilized in the seed portfolios may be subject to liquidity constraints over certain time periods and is subject to market conditions. A decline in the value of our seed capital would adversely impact our results of operations or financial condition.
The cost of insuring our business is meaningful and may increase.
Our insurance costs are meaningful and can fluctuate significantly from year to year. In addition, certain insurance coverage may not be available or may only be available at prohibitive costs. As we renew our insurance coverage, we may be subject to additional costs caused by premium increases, higher deductibles, co-insurance liability, changes in the size of our business or nature of our operations, litigation or acquisitions or dispositions. Higher insurance costs and incurred deductibles, as with any expense, would reduce our net income. In addition, we may obtain additional liability insurance for our directors and officers. There have been historical periods in which directors’ and officers’ liability insurance and errors and omissions insurance have been available only with limited coverage amounts, less favorable terms or at prohibitive cost, and these conditions could recur.
18
Our growth initiatives, including the development and introduction of new products and/or capabilities, may be unsuccessful, may expose us to risks and may not facilitate the growth of our business.
Our continued growth depends in part on our effectiveness in developing and introducing new products and/or capabilities. Such innovation may require significant time and resources, including upfront and ongoing expenses, as well as expose us to additional risks, including but not limited to legal and regulatory risks. There can be no assurances that we will correctly identify the strongest areas for growth, or that we will effectively develop and introduce products and/or capabilities in such areas and mitigate any additional risk related thereto. To the extent that our revenues associated with such products and/or capabilities do not increase as much as our related expenses, our profitability could be adversely affected.
Our outstanding indebtedness may impact our business and may restrict our growth and results of operations.
As of December 31, 2025, we had $200.0 million of long-term debt outstanding. For additional information regarding our long-term debt, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Capital Resources and Liquidity—Borrowings and Debt.”
We may incur additional indebtedness in the future for a variety of business reasons, including in relation to our share repurchases, for seed or co-investment capital, or for other strategic reasons. The level of our indebtedness has important consequences to investors in our securities. For example, our level of indebtedness may require us to use a substantial portion of our cash flow from operations to pay interest and principal on our debt, which would reduce the funds available to us for working capital, capital expenditures and other general corporate purposes and may limit our ability to pay future dividends. Too much debt may limit our ability to implement our business strategy; heighten our vulnerability to downturns in our business, the financial services industry or in the general economy and limit our flexibility in planning for, or reacting to, changes in our business and the financial services industry; limit our access to additional debt; or prevent us from taking advantage of business opportunities as they arise or successfully carrying out our plans to expand our business and our product offerings. Any of these consequences could have a material adverse effect on our financial condition or results of operations.
We may be unable to obtain sufficient capital and liquidity to meet the requirements of our business.
Our ability to finance our operations, strategic initiatives and maturing obligations is dependent on our future operating performance and other financing options. Any future inability to obtain financing on reasonable terms and with reasonable restrictions on the operation of our business could impair our liquidity, have a negative impact on our growth and negatively impact our financial condition.
Our business involves risks of potential litigation that could harm our business.
We may be named as defendants or co-defendants in lawsuits, or may be involved in disputes that include the threat of lawsuits seeking substantial damages. Any such legal action, whether threatened or actual, could result in reputational damage, loss of clients and assets, increased costs and expenses in resolving a claim, diversion of employee resources and resulting financial losses.
We make investment decisions on behalf of our clients that could result in substantial losses to those clients. If our clients suffer significant losses or otherwise are dissatisfied with our service, we could be subject to the risk of legal liability or actions alleging, among other theories, negligent misconduct, breach of fiduciary duty, breach of contract, unjust enrichment and/or fraud. These risks often are difficult to assess or quantify and their existence and magnitude often remain unknown for substantial periods of time, even after an action has been commenced. We may incur substantial legal expenses in defending against litigation commenced by a client or regulatory authority. Substantial legal liability levied on us could have a material adverse effect on our business, financial condition, or results of operations and could cause significant reputational harm.
19
Any significant limitation on the use of our facilities or the failure or security breach of our software applications or operating systems and networks, including the potential risk of cyber-attacks, could result in the accidental or unlawful destruction, loss, alteration, unauthorized disclosure of, or access to, confidential client information or personal data, damage to our reputation, additional costs, regulatory penalties and financial losses.
We depend upon our various centers of operation, including our information technology systems and those of our vendors, contractors, and other third-party partners who process information on our behalf, for the continued operations of our business. A disruption in the infrastructure that supports our business or prevents our employees from performing their job functions, including communication failures, natural disasters, terrorist attacks, third party cyber-attacks including ransomware, and international hostilities, may have a material impact on our ability to continue business operations without interruption. Insurance and other safeguards might not be available or might only partially reimburse us for our losses.
Although we have back-up systems and disaster recovery programs in place and test their uses periodically, there can be no assurance that the recovery programs will be sufficient to mitigate any harm that may result from a disruption or disaster. Additionally, it is possible that any such disruption or disaster could have a significant impact on the general economy, domestic and local financial and capital markets or specific industries, including the financial services industry.
A significant portion of our operations relies heavily on the secure processing, storage and transmission of confidential and other information as well as the monitoring of a large number of complex transactions. Like many other financial institutions, we have been subject to cyber-attacks and will continue to be subject to an increasing risk of cyber incidents from these activities. Cyber-attacks are growing in sophistication and come from a variety of sources, including criminal hackers, activists, state-sponsored intrusions, industrial espionage, and insider threats. We are required to expend significant resources in an effort to protect against security incidents and may be required or choose to spend additional resources or modify our business activities, particularly where required by applicable data privacy and security laws or regulations or industry standards. While we have implemented security measures, our technology systems, and those of our vendors, contractors, and other third-party partners who process information on our behalf, may still be vulnerable to security incidents, disruptions, cyber-attacks or similar events such as unauthorized access, computer malware, phishing attacks and other forms of social engineering, denial-of-service attacks, ransomware attacks, or other events that have a security impact, such as an authorized employee or vendor inadvertently causing the release of confidential information or third-party unauthorized access or account takeovers, which could materially damage our operations or cause the disclosure or modification of sensitive or confidential information. Breach of our technology systems through cyber-attacks, or failure to manage and secure our technology environment, could result in interruptions or malfunctions in the operations of our business, loss of valuable information, liability for stolen assets or information, remediation costs to repair damage caused by a breach, additional costs to mitigate against future incidents and litigation costs resulting from an incident. Moreover, accidental or unlawful destruction, loss, alteration, unauthorized disclosure of, or access to, personal data and confidential client information could harm our reputation and subject us to liability under the laws that protect personal data and confidential information, resulting in increased costs or loss of revenues. A successful attack could result in significant adverse consequences, including regulatory inquiries or litigation, increased costs and expenses including costs related to insurance and remediation of any security vulnerabilities, reputational damage, lost revenue, and fines or penalties.
20
We are subject to data protection laws including in the European Union (“EU”), United Kingdom (“U.K.”), United States (“U.S.”) and other jurisdictions, and any failure to comply with such legislation could adversely affect our business, reputation, results of operations and financial condition.
We are subject to privacy and security laws in the various jurisdictions in which we operate, obtain or store personally identifiable information. The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an increasing focus on privacy and data protection issues with the potential to affect our business. For example, certain of our processing activities are subject to the General Data Protection Regulation (EU) 2016/679 (“GDPR”), and also as it forms part of the law of England and Wales, Scotland and Northern Ireland by virtue of section 3 of the European Union (Withdrawal) Act 2018 and as amended by the Data Protection, Privacy and Electronic Communications (Amendments etc.) (EU Exit) Regulations 2019 (SI 2019/419) (“U.K. GDPR”), along with the Data Protection Act 2018 and the Data (Use and Access) Act in the U.K. (together “EU/U.K. Data Protection Laws”). The EU/U.K. Data Protection Laws have a wide territorial reach and apply to data controllers and data processors which have an establishment in the EU/U.K., or which offer goods or services to, or monitor the behavior of, data subjects in the EU and U.K. The EU/U.K. Data Protection Laws impose stringent operational requirements on data controllers and data processors. These include (i) accountability and transparency obligations which require organizations to demonstrate and record compliance with the EU/U.K. Data Protection Laws and to provide detailed information to data subjects regarding the processing of their personal data, (ii) obligations to consider data privacy as any new products or services are developed and to limit the amount of information they collect, process and store, (iii) ensuring and maintaining an appropriate level of security for personal data, and (iv) reporting breaches to data protection authorities and, in some cases, affected individuals. The EU/U.K. Data Protection Laws give strong enforcement powers to data protection authorities in the EU/U.K., and introduce significant penalties for non-compliance, with fines of up to 4% of total annual worldwide turnover or €20 million/£17.5 million (as applicable) (whichever is higher), depending on the type and severity of the breach.
In the United States, we are subject to rules adopted pursuant to the Gramm Leach Bliley Act and an ever-increasing number of state laws and regulations, such as the California Consumer Privacy Act, as amended by the California Privacy Rights Act (together, the “CCPA”). The CCPA regulates companies’ use and disclosure of the personal information of California residents and grants California residents several rights with respect to their personal information. The CCPA also provides for civil penalties for violations, including statutory fines for noncompliance, as well as a limited private right of action in connection with certain data breaches, and establishes a new regulatory agency to implement and enforce the law. Moreover, comprehensive privacy laws similar to the CCPA are either in effect, have been enacted or are being considered in multiple other states. All of these new privacy laws and others that we expect to be developed and enacted going forward may impose additional data protection obligations and potential liability on companies such as ours doing business in those states. The evolving patchwork of differing state and federal privacy and data security laws increases the cost and complexity of operating our business and increases our exposure to liability, including from third-party litigation and regulatory investigations, enforcement, fines and penalties. In addition, the interpretation of EU/U.K. Data Protection Laws, the CCPA, and other privacy laws to which we are subject around the world can be uncertain, and as business practices are challenged by regulators, data subjects and consumer protection agencies, it is possible that these laws may be interpreted and applied in a manner that is inconsistent with our data protection practices. Compliance with data privacy and security regulations can require allocation of significant resources as well as changes in operations and non-compliance can result in substantial fines. Any failure or perceived failure by us or our employees, representatives, contractors, consultants, collaborators, or other third parties to comply with such requirements or adequately address privacy and security concerns, even if unfounded, could result in additional cost and liability to us, damage our reputation, and adversely affect our business and results of operations.
21
The failure of a counterparty to meet its obligations could affect our business adversely.
We routinely execute transactions with counterparties in the financial industry and for the provision of services that are important to the business, and we may engage in transactions with counterparties as part of our corporate finance management function and for the provision of services, including insurance protection. As a result, we and our clients have exposure to the credit, operational and other risks posed by such counterparties, including the risk of default by or bankruptcy of a counterparty. The failure of a counterparty to meet its obligations or provide the services or insurance protection we depend on for these or other reasons could adversely affect our ability to conduct our business and result in loss of client assets and potential liability.
We are subject to the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and other anti-corruption laws, as well as export control laws, customs laws, sanctions laws, anti-facilitation of tax evasion laws and other laws governing our operations. If we fail to comply with these laws, we could be subject to civil or criminal penalties, other remedial measures, and legal expenses, which could adversely affect our business, results of operations and financial condition.
Our operations are subject to anti-corruption laws, including the U.S. Foreign Corrupt Practices Act, (the “FCPA”), the U.K. Bribery Act 2010 (the “Bribery Act”), and other anti-corruption laws that apply in countries where we do business. The FCPA, the Bribery Act and other applicable anti-corruption laws generally prohibit us and our employees and intermediaries from paying bribes, receiving bribes or making other prohibited payments to government officials or other persons to obtain or retain business or gain some other business advantage. We and our commercial partners operate in a number of jurisdictions that may pose an elevated risk of corruption, and we participate in collaborations and relationships with third parties whose actions could potentially subject us to liability under FCPA, the Bribery Act or local anti-corruption laws.
We are also subject to other laws and regulations governing our international operations, including applicable export control regulations, economic sanctions on countries or persons, customs requirements currency exchange regulations, and anti-facilitation of tax evasion rules, or collectively Trade Control Laws. As with anti-corruption laws, misconduct by third parties could potentially subject us to liability under Trade Control Laws.
There is no assurance that we will be completely effective in ensuring our compliance with all applicable anti-corruption laws or Trade Control Laws. In addition, we cannot predict the nature, scope or effect of future regulatory requirements to which our internal operations might be subject or the manner in which existing laws might be administered or interpreted. If we are not in compliance with anti-corruption laws or Trade Control Laws, we may be subject to criminal and civil penalties, disgorgement and other sanctions and remedial measures, and legal expenses, which could have an adverse impact on our business, financial condition, results of operations and liquidity. Likewise, any investigation of any potential violations of anti-corruption laws or Trade Control Laws by U.K., U.S. or other authorities could also have an adverse impact on our reputation, business, results of operations and financial condition.
Risks Related to Our Industry
We operate in a competitive environment.
The investment management industry is highly competitive, with competition based on a variety of factors, including investment performance, investment management fee rates, continuity of investment professionals and client relationships, the quality of services provided to clients, reputation and the strategies offered. We compete against a broad range of domestic and international asset management firms, broker-dealers, hedge funds, investment banking firms and other financial institutions. We directly compete against these organizations with respect to investment products, distribution channels, opportunities to acquire other investment management firms and retention and recruitment of talent. The capital resources, scale, name recognition and geographic footprints of many of these organizations are greater than ours. The recent trend toward consolidation in the investment management industry, and the financial services industry in general, has served to increase the size and strength of a number of our competitors. Some investors may prefer to invest with an investment manager that is not publicly
22
traded based on the perception that a publicly traded asset manager may focus on the manager’s own growth to the detriment of investment performance for clients. Some competitors may operate in a different regulatory environment than we do, which may give them certain competitive advantages in the investment products and portfolio structures that they offer.
Furthermore, the development and use of various technologies based on machine learning and AI is expanding rapidly in our industry. To the extent we do not effectively avail ourselves of new technologies, others in our industry may have a competitive advantage over us, which could have a material adverse effect on our financial condition and results of operations.
Our ability to attract assets also is dependent upon our ability to offer a mix of products and services that meet client demand and our ability to maintain investment management fees at competitive levels. When asset classes or products that we do not offer are in favor with either existing or potential clients, we will miss the opportunity to attract and manage these assets and face the risk of assets being withdrawn in favor of competitors who manage the asset classes and/or provide these products. If we are unable to compete effectively in the market, our results of operations and potential business growth could be adversely affected.
Our sole business is asset management. As a result, we may be more impacted by trends and issues and more susceptible to negative events impacting us and the asset management industry than other more diversified asset managers or other financial services companies that provide asset management and other financial services.
We operate in a highly regulated industry, and continually changing federal, state, local and foreign laws and regulations could materially adversely affect our business, financial condition and results of operations.
The investment management business is highly regulated and, as a result, we are required to comply with a wide array of domestic and international laws and regulations. The requirements imposed by our regulators are designed to ensure the integrity of the financial markets and to protect customers and other third parties who deal with us, and are not designed to protect our stockholders. Accordingly, these regulators often serve to limit our activities, including through client protection and market conduct requirements.
Acadian LLC is subject to extensive regulation in the U.S. through its primary regulator, the SEC, under the Advisers Act. To the extent Acadian LLC acts as investment adviser or sub-adviser to registered investment companies, it must also comply with the terms of the Investment Company Act and the rules thereunder. The Advisers Act imposes numerous obligations on registered investment advisers, including fiduciary, record keeping, advertising and operational requirements, disclosure obligations, and prohibitions on fraudulent activities. The Investment Company Act regulates the structure and operations of registered investment companies and imposes additional obligations on advisers to registered investment companies, including detailed disclosure and regulatory requirements applicable to the registered investment companies and additional compliance responsibilities which must strictly be adhered to by the funds and their advisers. Acadian LLC may also be subject to the rules and regulations adopted by the Commodity Futures Trading Commission, under the Commodity Exchange Act; by the Department of Labor, under ERISA; the Financial Industry Regulatory Authority, Inc. and state regulators.
23
We also are subject to the regulatory environments of the non-U.S. jurisdictions in which we operate, some of which also recently implemented or are in the process of implementing changes in regulations. In the U.K., we are subject to regulation by the Financial Conduct Authority, which imposes a comprehensive system of regulation on investment advisers and the manner in which we conduct our business. We may also be registered from time to time in jurisdictions outside of the United States and will be subject to applicable regulation in those jurisdictions. We additionally are subject to regulation relating to the offer and sale of financial products in each of the EU countries in which we operate. The system of financial regulation outside the United States continues to develop and evolve and, as a result, the rules to which we are subject (including rules relating to the remuneration of staff) are and will continue to be subject to change. As we execute on our growth strategy and continue to expand our distribution efforts into non-U.S. jurisdictions, including other member countries of the EU, Latin America, the Middle East and Asian countries, we may be required to register with additional foreign regulatory authorities or otherwise comply with non-U.S. rules and regulations that currently are not applicable to our business and with respect to which we may have limited or no compliance experience. Our lack of experience in complying with any such non-U.S. or non-English laws and regulations may increase our risk of becoming a party to litigation or subject to regulatory actions. Additionally, one or more of the jurisdictions in which we operate may require our stockholders to seek the approval of, or provide notice to, an applicable regulator before acquiring a substantial amount of our outstanding shares.
Developments in applicable regulatory environments may include heightened and additional examinations and inspections by regulators and the imposition of additional reporting and disclosure obligations. Regulators also may take a more aggressive posture on bringing enforcement proceedings which could result in fines, penalties and additional remedial activities.
Policy and legislative changes in the U.S. and in other countries are affecting many aspects of financial regulation. Our business, results of operations and financial condition may be adversely affected as a result of new or revised legislation or regulations or by changes in the interpretation or enforcement of existing laws and regulations in any of the jurisdictions in which we conduct business. Our ability to function in this legislative and regulatory environment will depend on our ability to monitor and promptly react and adapt to legislative and regulatory changes, including situations where such changes in regulatory requirements may be driven by internal factors. It is impossible to determine the extent of the impact of any new laws, regulations or initiatives that may be proposed, or whether any of the proposals will become law. Any new laws or regulations could make compliance more difficult and expensive and affect the manner in which we conduct business.
Failure to comply with applicable laws or regulations could result in fines, suspension or revocation of Acadian LLC’s registration as an investment adviser, suspensions of individual employees, revocation of licenses to operate in certain jurisdictions or other sanctions, which could materially adversely affect our business, financial condition and results of operations. Even if an investigation or proceeding did not result in a fine or sanction, or the fine or sanction imposed against us or our respective employees by a regulator were small in monetary amount, the adverse publicity relating to an investigation, proceeding or imposition of a fine or sanction could cause us to suffer financial loss, harm our reputation and cause us to lose business or fail to attract new business which would have a direct adverse impact on our business, financial condition and results of operations.

Risks Related to Our Ownership Structure and Governance
Paulson has meaningful ability to influence our business.
As of December 31, 2025, Paulson & Co. Inc. (“Paulson”) and related parties thereof held 21.8% of our common stock. This concentration of ownership may have the effect of delaying or preventing a change in control of us or discouraging others from making tender offers for our common stock. It also may make it difficult for other stockholders to replace management and may adversely impact the trading price of our common stock because investors often perceive disadvantages in owning common stock in companies with significant stockholders. Additional repurchases of our common stock could, without any action by Paulson, further increase Paulson’s concentration of ownership. Additionally, Paulson has the right to appoint one director so long as it holds at least 7% of our outstanding common stock. Paulson also has the right to transfer this appointment right to a transferee that acquires from Paulson the foregoing percentage of our common stock, at which point such unknown third party may have a meaningful ability to influence our business.
Future sales of our common stock by us, Paulson or other stockholders could cause our share price to decline.
If we, Paulson or other stockholders sell, or indicate an intention to sell, or there is a perception that we or they might sell, a substantial number of shares of our common stock in the public market or in privately negotiated transactions, the trading price of our common stock could decline below the current trading level.
Sales by Paulson or other stockholders or the possibility that these sales may occur also may make it more difficult for us to raise additional capital by selling equity securities in the future, at a time and price that we deem appropriate.
We cannot predict the size of future issuances or sales of our common stock or the effect, if any, that future issuances and sales of our common stock may have on the market price of our common stock. Sales or distributions of substantial amounts of our common stock, including shares issued in connection with an acquisition, or the perception that such sales or distributions could occur, may cause the market price of our common stock to decline.
Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or agents.
Our amended and restated certificate of incorporation provides that, unless we consent in writing to an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, employees or agents to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law or (iv) any action asserting a claim that is governed by the internal affairs doctrine, in each case subject to the Court of Chancery having personal jurisdiction over the indispensable parties named as defendants therein and the claim not being one which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery or for which the Court of Chancery does not have subject matter jurisdiction. Any person purchasing or otherwise acquiring any interest in any shares of our capital stock shall be deemed to have notice of and to have consented to this provision of our amended and restated certificate of incorporation. This choice of forum provision may limit our stockholders’ ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and our directors, officers, employees and agents. Alternatively, if a court were to find this provision of our restated certificate of incorporation inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business and financial condition. The exclusive forum provision described above does not impact the Federal courts’ exclusive jurisdiction over Exchange Act claims or the Federal and state courts’ concurrent jurisdiction over Securities Act claims.
25
There can be no assurance that we will repurchase shares of our common stock or that we will repurchase shares of our common stock at favorable prices.
Our Board of Directors may from time to time authorize us to repurchase shares of our common stock. The amount and timing of share repurchases are subject to market conditions, stock price and other factors, including compliance with all respective laws and our applicable agreements. The amount, timing and execution of repurchase shares of our common stock will depend upon, among other factors, our cash balances and potential future capital requirements for strategic transactions, our results of operations, our financial condition, tax laws and other factors that we may deem relevant. A reduction in repurchases under, or the completion of, our share repurchase program could have a negative effect on our stock price. We can also provide no assurance that we will repurchase shares of our common stock at favorable prices, if at all.
Risks Related to Our Tax Matters
Our global effective tax rate is subject to a variety of different factors, which could create volatility in that rate, expose us to greater than anticipated tax liabilities and cause us to adjust previously recognized tax assets and liabilities.
We are subject to income taxes in the U.S., the U.K. and many other jurisdictions. As a result, our global effective tax rate from period to period can be affected by many factors, including our global mix of earnings, the tax characteristics of our income and changes in tax legislation. Significant judgment is required in determining our worldwide provision for income taxes, and our determination of our tax liability is always subject to review by applicable tax authorities.
We cannot provide any assurances as to what our tax rate will be in any period because of, among other things, uncertainty regarding the nature and extent of our business activities in any particular jurisdiction in the future and the tax laws of such jurisdictions, as well as changes in U.S. and other tax laws, treaties and regulations. Our actual global tax rate may vary from our expectation and that variance may be material.
Failure to comply with the tax laws of the U.S., the U.K. or other jurisdictions, which laws are subject to potential legislative, judicial or administrative change and differing interpretations, possibly on a retroactive basis, may result in erroneous filings, adjustments to previously recognized tax assets and liabilities, negative impact to income and reputational damage.
We are subject to a range of taxes and tax audits and may be subject to future audits and examinations by both foreign and domestic taxing authorities. Tax and other regulatory authorities may disagree with tax positions taken by us based on our, or their, interpretations of the relevant tax laws, including, for example, with respect to our tax positions related to the redomestication or to prior reorganizations, which could result in erroneous filings, retroactive adverse impact on income, the loss of tax benefits and reputational damage. The resolution of such audits and examinations could impact our tax rate in future periods, as would any reclassification or other matter (such as changes in applicable accounting rules) that increases the amounts we have provided for income taxes in our Consolidated Financial Statements. We will regularly assess the likelihood of favorable or unfavorable outcomes resulting from these audits and examinations to determine the adequacy of our provision for income taxes, which will require estimates and judgments. Although we will make these tax estimates and judgments on a reasonable basis, there can be no assurance that the tax authorities will agree with such estimates and judgments. From time to time, we may have to engage in litigation to attempt to achieve the results reflected in our estimates, which may be time-consuming and expensive and may have other adverse impacts. There can be no assurance that we will be successful in any such litigation or other attempts to mitigate adverse effects resulting from such audits or examinations or that any final determination of our tax liability will not be materially different from the historical treatment reflected in our historical income tax provisions and accruals. Our inability to mitigate the negative consequences of any resolution of audits and examinations could cause our global tax rate to increase, our use of cash to increase and our financial condition and results of operations to suffer.
26
Changes in tax laws could have an adverse impact on our business, financial condition, and results of operations.
We are subject to income taxes in the U.S., the U.K. and many other jurisdictions. Changes to income tax laws and regulations, or the interpretation of such laws, in any of the jurisdictions in which we operate could significantly increase our effective tax rate and ultimately reduce our cash flows from operating activities and otherwise have a material adverse effect on our financial condition, results of operations and cash flows. The U.S. Congress, the Organization for Economic Co-operation and Development (“OECD”), and other government agencies in jurisdictions in which we conduct business have maintained a focus on the taxation of multinational companies. The OECD has recommended changes to numerous long-standing international tax principles through its base erosion and profit shifting (“BEPS”) project, and many jurisdictions have begun codifying those recommendations into law. These and other changes to tax laws and related regulations, to the extent adopted, may increase tax uncertainty and/or our effective tax rate, result in higher compliance cost and adversely affect our provision for income taxes, results of operations and/or cash flows.
General Risk Factors
The market price of our common stock and the broader equity markets have been, and may continue to be, volatile.
The market price of our common stock has been and may continue to be volatile, and equity markets have experienced and may continue to experience significant price and volume fluctuations. Among the factors that may affect our stock price are the following:
•public health emergencies;
•speculation in the investment community or the press about, or actual changes in, our competitive position, organizational structure, executive team, operations, financial condition, financial reporting and results, ability to maximize shareholder returns or plans to engage in strategic transactions by us or others in our industry;
•the announcement of mergers, acquisitions, dispositions or new products or services by us or others in our industry;
•announcements of our financial results, including changes in net client cash flows and assets under management, changes in earnings estimates by the investment community, and variations between estimated financial results and actual financial results; and
•the pricing structure for products offered by us or our competitors.
Changes in general conditions and volatility in the economy, the financial markets and our industry, and other developments affecting us or our competitors, as well as geopolitical, regulatory, economic, and business factors unrelated to us, could cause the market price of our common stock to fluctuate substantially. Declines in the market price of our common stock or failure of the market price to increase could also harm our ability to retain key employees, reduce our access to capital and otherwise harm our business.
The carrying value of goodwill and other intangible assets on our balance sheet could become impaired, which would adversely affect our financial condition and results of operations.
We have recorded goodwill and intangible asset impairments in the past and could incur such charges in the future if acquisitions occur and we take on more goodwill. We review the carrying value of goodwill and intangible assets not subject to amortization on an annual basis, or more frequently if indications exist suggesting that the fair value of our intangible assets may be below their carrying values. We test the values of intangible assets subject to amortization whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Should such review indicate impairment, a write-down of the carrying value of goodwill or the intangible asset could occur, resulting in a non-cash charge that may, in turn, affect our reported results of operations, financial condition and shareholders’ equity.
27
Our ability to pay regular dividends to our stockholders is subject to the discretion of our Board of Directors and may be limited by our structure and applicable provisions of Delaware law.
Any declaration of dividends will be at the discretion of our Board of Directors, and will depend on our financial condition, earnings, cash needs, regulatory constraints, capital requirements and any other factors that our Board of Directors deems relevant in making such a determination. However, our ability to make such distributions will be subject to our operating results, which are impacted by the ability of Acadian LLC to make distributions to us, cash requirements and financial condition, the applicable provisions of Delaware law that may limit the amount of funds available for distribution, our compliance with covenants and financial ratios related to existing or future indebtedness, including under our notes and our credit facilities, and our other agreements with third parties. In addition, we are dependent upon the ability of Acadian LLC to generate earnings and cash flows and distribute them to us so that we may pay dividends to our stockholders. As a consequence of these various limitations and restrictions, we may not be able to make, or may have to reduce or eliminate, the payment of dividends on our common stock.
Our management devotes substantial time to compliance with our public company legal and reporting obligations.
We are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, (the “Exchange Act”), and are required to implement specific corporate governance practices and adhere to a variety of reporting requirements under the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley”), and the related rules and regulations of the SEC, as well as the rules of the NYSE. The Exchange Act requires us to file annual, quarterly and current reports with respect to our business and financial condition. Our management and other personnel devote substantial time to compliance with our public company obligations. Moreover, these rules and regulations increase our legal and financial compliance costs and make some activities more time-consuming and costly.
In addition, Sarbanes-Oxley requires, among other things, that we maintain effective internal control over financial reporting and disclosure controls and procedures. In particular, we perform system and process evaluations and we have tested our internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting, as required by Section 404 of Sarbanes-Oxley, and obtain an auditor attestation as to the effectiveness of our internal controls.
Testing may reveal material weaknesses or other deficiencies in our internal control over financial reporting. Our compliance with Section 404 has required that we incur additional accounting expense and expend additional management time on compliance-related issues. Moreover, if at any time we are not able to comply with the requirements of Section 404 in a timely manner, or if we identify material weaknesses or other deficiencies in our internal control over financial reporting, the market price of our common stock could decline, and we could be subject to sanctions or investigations by the NYSE, the SEC or other regulatory authorities, which would require additional financial and management resources.
28
Item 1B. Unresolved Staff Comments.
There are no unresolved written comments that were received from the Securities and Exchange Commission staff 180 days or more before the end of our fiscal year relating to our periodic or current reports under the Securities Exchange Act of 1934, as amended.
Item 1C. Cybersecurity.
Risk management and strategy
We have adopted processes designed to identify, assess and manage material risks from cybersecurity threats. Those processes include response to and an assessment of internal and external threats to the security, confidentiality, integrity and availability of our data and systems along with other material risks to our operations, at least annually or whenever there are material changes to our systems or operations.
Our Management Risk Committee (MRC) collaborates with our Chief Technology Officer (CTO) and Chief Information Security Officer (CISO) along with the IT Department to evaluate and address cybersecurity risks in alignment with our business objectives and operational needs. Our CTO and CISO along with the IT Department implement processes and technologies to provide security monitoring and vulnerability management. We have an incident response plan in place with designated roles and responsibilities for responding to and escalating cybersecurity events and incidents.
As part of our risk management process, we engage outside providers to conduct periodic penetration testing and vulnerability assessments.
We maintain a third-party risk management program that includes vendor due diligence at onboarding, periodic assessments, and continuous risk monitoring. Assessments include reviews of security controls and cybersecurity questionnaires or other technical evaluations. In addition, we maintain a vendor risk register and review risk ratings semi-annually.
As of the date of this report, we have not experienced a cybersecurity incident that resulted in a material effect on our business strategy, results of operations, or financial condition.
Governance
Our Board of Directors provides oversight of the Company’s cybersecurity risk management program.The Audit Committee of our Board of Directors has primary responsibility for oversight of cybersecurity and is briefed on cybersecurity risks quarterly and following any material cybersecurity incidents.
Our cybersecurity program is managed by our CTO and CISO, who have served in this role since 2025.Our CISO has over 25 years of industry experience in information technology and maintains industry certifications such as the ISC2 CISSP.
Reporting to the Audit Committee of our Board of Directors, our CTO and CISO may address overall assessment of the Company’s compliance with our cybersecurity policies and procedures, risk management, service provider arrangements, testing results and security incident response and makes recommendations for changes and updates to policies, procedures, and technologies related to cybersecurity and IT risk management.
29
Item 2. Properties.
Our principal executive office is located at 200 State Street, Suite 601A, Boston, Massachusetts 02109. Acadian LLC has its own primary office in Boston, MA where core investment management activities take place. In addition, Acadian LLC has leased secondary offices to support research, distribution and client servicing. Key locations for secondary offices include (but are not limited to) London, Singapore and Sydney. We believe existing facilities are appropriate in size, location and functionality to meet current and future business requirements.
Item 3. Legal Proceedings.
From time to time, we may be party to various claims, suits and complaints in the ordinary course of our business. Although the amount of liability that may result from these matters cannot be ascertained, we do not currently believe that, in the aggregate, they will result in liabilities material to our consolidated financial condition, future results of operations or cash flow.
Item 4. Mine Safety Disclosures.
Not applicable.

References to Hold Co refer to AAMI and its subsidiaries excluding Acadian Asset Management LLC (“Acadian LLC”). Unless we state otherwise or the context otherwise requires, references in this Annual Report on Form 10-K to “OM plc” refer to Old Mutual plc, our former parent. None of the information in this Annual Report on Form 10-K constitutes either an offer or a solicitation to buy or sell Acadian LLC’s products or services, nor is any such information a recommendation for Acadian LLC’s products or services.
The following discussion of our financial condition and results of operations should be read in conjunction with our Consolidated Financial Statements and related notes which appear in this Annual Report on Form 10-K in Item 8, Financial Statements and Supplementary Data.
This discussion contains forward-looking statements that involve risks and uncertainties. See “Forward-Looking Statements” for more information. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including those discussed below and elsewhere in this Annual Report on Form 10-K.
This Management’s Discussion and Analysis of Financial Condition and Results of Operations, or MD&A, is designed to provide a reader of our financial statements with a narrative from the perspective of our management on our financial condition, results of operations, liquidity and certain other factors that may affect our future results.
Our MD&A is presented in five sections:
•Overview provides a brief description of our business. It includes information on our reporting segment, a summary of The Economics of Our Business and an explanation of How We Measure Performance using a non-GAAP measure which we refer to as economic net income, or ENI. This section also provides a Summary Results of Operations and information regarding our Assets Under Management by strategy, client type and client location, and net flows by segment, client type and client location.
•U.S. GAAP Results of Operations for the years ended December 31, 2025, 2024 and 2023 includes an explanation of changes in our U.S. GAAP revenue, expense and other items over the last three years as well as key U.S. GAAP operating metrics.
•Non-GAAP Supplemental Performance Measure—Economic Net Income and Segment Analysis includes an explanation of the key differences between U.S. GAAP net income and ENI, the key measure management uses to evaluate our performance. This section also provides a reconciliation between U.S. GAAP net income attributable to controlling interests and ENI for the years ended December 31, 2025, 2024 and 2023, as well as a reconciliation of key ENI operating items including ENI revenue and ENI operating expenses. This section also provides key non-GAAP operating metrics. In addition, this section provides segment analysis for our business segment.
•Capital Resources and Liquidity discusses our key balance sheet data. This section discusses Cash Flows from the business; Working Capital and Long-Term Debt; Borrowings and Debt; Other Compensation Liabilities; Adjusted EBITDA; Future Capital Needs; and Commitments, Contingencies and Off-Balance Sheet Obligations. The discussion of Adjusted EBITDA includes an explanation of how we calculate Adjusted EBITDA and a reconciliation of U.S. GAAP net income attributable to controlling interests to Adjusted EBITDA.
33
•Critical Accounting Policies and Estimates provides a discussion of the key accounting policies and estimates that we believe are the most critical to an understanding of our results of operations and financial condition. These accounting policies and estimates require complex management judgment regarding matters that are highly uncertain at the time the policies were applied and estimates were made.
Overview
We are a holding company that operates a systematic investment management business through our majority owned subsidiary, Acadian LLC. Acadian LLC offers institutional investors across the globe access to a diversified array of systematic investment strategies designed to meet a range of risk and return objectives. Acadian LLC is a leading systematic investment manager of active equity products. Notable product lines and capabilities include Emerging Equity, Non-U.S. Equity, Global Equity, Small Cap Equity, Enhanced Equity, Equity Extensions, Systematic Credit, and Alternatives. Acadian LLC comprises our Quant & Solutions reportable segment:
•Quant & Solutions—incorporates strategies that utilize advanced technology to collect and analyze data, aiming to identify mispriced assets and generate attractive risk-adjusted returns for investors; portfolios include Emerging Equity, Non-U.S. Equity, Global Equity, Small Cap Equity, Enhanced Equity, Equity Extensions, and Systematic Credit. This segment consists of our ownership interest in Acadian LLC.
Hold Co is included within the Unallocated Corporate expenses category.
Under U.S. GAAP, Acadian LLC is consolidated into our financial statements. We may also be required to consolidate Acadian LLC’s sponsored investment entities, or Funds, due to the nature of our decision-making rights, our economic interests in these Funds or the rights of third-party clients in those Funds.
34
The Economics of Our Business
Our profitability is affected by a variety of factors including the level and composition of our average assets under management, or AUM, fee rates charged on AUM and our expense structure. We earn management fees based on assets under management. The majority of our management fees are calculated based on average AUM (calculated on either a daily or monthly basis) with the remainder of our management fees calculated based on period-end AUM. Changes in the levels of our AUM are driven by market investment performance and net client cash flows. We may also earn performance fees when certain accounts differ in relation to relevant benchmarks or exceed required returns. As of December 31, 2025, approximately $23 billion, or 13%, of our AUM was in accounts with incentive fee features in which we participate in the performance fee. The majority of these performance fees are calculated based on value added over the relevant benchmarks on a rolling one-year basis.
Our largest expense item is compensation and benefits paid to our employees, which consists of both fixed and variable components. Fixed compensation and benefits represents base salaries and wages, payroll taxes and the costs of our employee benefit programs. Variable compensation is comprised of variable compensation at both Hold Co and Acadian LLC. Hold Co variable compensation includes discretionary annual bonuses and may be paid in the form of cash or AAMI equity. Acadian LLC variable compensation, calculated as described below, may be awarded in cash, equity, or profit interests.
The arrangement in place with Acadian LLC results in the sharing of economics between us and key management personnel using a profit-sharing model. Profit sharing affects two elements within our earnings: (i) the calculation of variable compensation and (ii) the level of Acadian LLC’s equity or profit interests distribution to its employees.
Variable compensation includes the portion of earnings that is contractually allocated to Acadian LLC employees as a bonus pool, typically representing a percentage of earnings before variable compensation, which is measured as revenues less fixed compensation and benefits and other operating and administrative expenses. Profits after variable compensation are shared between us and Acadian LLC key employee equity holders according to our respective equity or profit interests ownership. The sharing of profits in this manner ensures that the economic interests of Acadian LLC key employees and ours are aligned, both in terms of generating strong annual earnings as well as investing those earnings back into the business in order to generate growth over the long term. We view profit sharing as an attractive operating model, as it allows us to share in the benefits of operating leverage as the business grows, and ensures all equity and profit interests holders are incentivized to achieve that growth.
Equity or profit interests owned by Acadian LLC key employees are awarded as part of their variable compensation arrangement. Over time, Acadian LLC key employee-owned equity or profit interests are recycled from one generation of employee-owners to the next, either by the next generation purchasing equity or profit interests directly from retiring principals, or by key employees forgoing cash bonuses in exchange for the equivalent value in Acadian LLC equity or profit interests. The recycling of equity or profit interests is often facilitated by Hold Co; see “—U.S. GAAP Results of Operations—U.S. GAAP Expenses—Compensation and Benefits Expense” for a further discussion. Employee equity is valued at a fixed multiple of profits, so employees have transparency into both their earning potential in any year from the bonus pool and share of profits, as well as the current value of their equity and the long-term potential to realize value from its growth.
In this structure, key employees who are managing the business have incentives to manage for profit, but also to manage the business prudently, in the interest of their clients, and invest for growth, since they will benefit over the long term as both employees and equity holders. In this way, key employees are aligned with the public stockholders to generate profits and growth over time.
35
How We Measure Performance
We manage our business based on one segment, reflecting how our management assesses the performance of our business.
In measuring and monitoring the key components of our earnings, our management uses a non-GAAP financial measure, ENI, to evaluate the financial performance of, and to make operational decisions for, our business. We also use ENI to make resource allocation decisions, determine appropriate levels of investment or dividend payout, manage balance sheet leverage, determine variable compensation and Acadian LLC equity distributions, and incentivize management. It is an important measure in evaluating our financial performance because we believe it most accurately represents our operating performance and cash generation capability.
ENI differs from net income determined in accordance with U.S. GAAP as a result of both the reclassification of certain income statement items and the exclusion of certain non-cash or non-recurring income statement items. In particular, ENI excludes non-cash charges representing the changes in the value of Acadian LLC equity and profit interests held by key employees, the results of discontinued operations which are no longer part of our business, restructuring costs, capital transaction costs, seed capital and co-investment gains, losses and related financing costs and that portion of consolidated Funds which are not attributable to our stockholders.
ENI revenue is primarily comprised of the fee revenues paid to us by our clients for our advisory services. Revenue included within ENI differs from U.S. GAAP revenue in that it excludes amounts from consolidated Funds which are not attributable to our stockholders.
ENI expenses are calculated to reflect all usual expenses from ongoing continuing operations attributable to our stockholders. Expenses included within ENI differ from U.S. GAAP expenses in that they exclude amounts from consolidated Funds which are not attributable to our stockholders, revaluations of Acadian LLC key employee owned equity and profit interests, amortization and impairment of acquired intangibles and other acquisition-related items, and certain other non-cash expenses.
“Non-controlling interests” is a concept under U.S. GAAP that identifies net components of revenues and expenses that are not attributable to our stockholders. For example, the portion of the net income (loss) of any consolidated Fund that is attributable to the outside investors or clients of the consolidated Fund is included in “Non-controlling interests” in our Consolidated Financial Statements. Conversely, “controlling interests” is the portion of revenue or expense that is attributable to our stockholders.
For a more detailed discussion of the differences between U.S. GAAP net income and economic net income, see “—Non-GAAP Supplemental Performance Measure — Economic Net Income and Segment Analysis.”

Assets Under Management
In the first quarter of 2025, we changed the presentation of our AUM. The new presentation reflects better alignment of our view on the business and distribution channels. We made certain reclassifications between strategies, client type and client location groupings to better reflect the underlying AUM. In the AUM tables below, all periods have been reclassified to conform to the new presentation.
Our total assets under management were $177.5 billion, $117.3 billion and $103.7 billion as of December 31, 2025, December 31, 2024 and December 31, 2023, respectively.
The following table presents our assets under management by strategy as of each of the dates indicated:

At December 31, 2025, our total assets under management were $177.5 billion, an increase of $60.2 billion or 51.3%, compared to $117.3 billion at December 31, 2024. The assets under management at December 31, 2024 represented an increase of $13.6 billion or 13.1% compared to $103.7 billion at December 31, 2023. The change in assets under management during the year ended December 31, 2025 reflects net market appreciation of $30.8 billion and net flows of $29.4 billion, including reinvested income and distributions of $3.6 billion. The change in assets under management during the year ended December 31, 2024 reflects net market appreciation of $11.8 billion and net flows of $1.8 billion, including reinvested income and distributions of $3.3 billion. The change in assets under management during the year ended December 31, 2023 reflects net market appreciation of $12.4 billion and net flows of $(2.3) billion, including reinvested income and distributions of $3.6 billion. Market appreciation or depreciation reported in current and prior periods includes changes in equity prices, as well as the impact from exchange rate fluctuations on our foreign denominated AUM. Given a substantial portion of our AUM is denominated in foreign currencies, foreign exchange rate movements during the period can impact AUM when the strength of the U.S. dollar changes relative to other currencies.
41
For the year ended December 31, 2025, our net inflows were highest in company history at $29.4 billion compared to net inflows of $1.8 billion for the year ended December 31, 2024 and net outflows of $(2.3) billion for the year ended December 31, 2023. The change in net flows for the year ended December 31, 2025 was primarily driven by strong gross inflows, which increased to $55.0 billion for the year ended December 31, 2025. The change in net flows for the year ended December 31, 2024 was primarily driven by gross sales, which increased to $21.2 billion for the year ended December 31, 2024. The change in net flows for the year ended December 31, 2023 was primarily due to lower outflows in certain strategies, partly as a result of client-driven asset re-allocations. Reinvested income and distributions of $3.6 billion, $3.3 billion, and $3.6 billion are reflected in the net flows for the years ended December 31, 2025, 2024 and 2023, respectively.

Net income attributable to controlling interests $ 80.0 $ 85.0 $ 65.8
Pre-tax income attributable to controlling interests $ 116.6 $ 123.9 $ 95.2
U.S. GAAP Revenues
Our U.S. GAAP revenues principally consist of:
i.management fees earned based on our overall weighted average fee rate charged to our clients and the level of assets under management;
ii.performance fees earned when our investment performance over agreed time periods for certain clients has differed from predetermined hurdles; and
iii.revenue from consolidated Funds, a portion of which is attributable to the holders of non-controlling interests in consolidated Funds.
Management Fees
Our management fees are a function of the fee rates charged to our clients, which are typically expressed in basis points, and the levels of our assets under management. Our effective management fee rate will vary from period to period based on several factors, including changes in the mix of assets under management caused by market movements and client flows.
Average basis points earned on average assets under management were 35.9 bps for the year ended December 31, 2025, 38.4 bps for the year ended December 31, 2024 and 37.9 bps for the year ended December 31, 2023. The greatest driver of increases or decreases in the average fee rate are changes in the mix of our assets under management caused by net inflows or outflows in certain asset classes, and disproportionate market movements.
Year ended December 31, 2025 compared to year ended December 31, 2024: Management fees increased $86.6 million, or 20.1%, from $431.1 million for the year ended December 31, 2024 to $517.7 million for the year ended December 31, 2025. The increase was mainly driven by higher levels of average assets under management, partly offset by a lower blended fee rate on assets under management due to the change in asset mix in the years ended December 31, 2025 and 2024. Average assets under management increased 28.5%, from $112.3 billion for the year ended December 31, 2024 compared to $144.3 billion for the year ended December 31, 2025, driven by both record net flows and positive equity market in the year ended December 31, 2025. Net flows were mainly driven by gross sales in the lower fee Enhanced strategy. The change in overall blended fee rate was primarily due to the Enhanced strategy, as total Enhanced AUM increased 13% to 23% at the end of 2025.
Year ended December 31, 2024 compared to year ended December 31, 2023: Management fees increased $57.9 million, or 15.5%, from $373.2 million for the year ended December 31, 2023 to $431.1 million for the year ended December 31, 2024. The increase was mainly driven by higher levels of average assets under management and an improvement in blended average basis points on assets under management, due to fee rates on inflows being higher than fee rates on outflows in the years ended December 31, 2024 and 2023. Average assets under management increase 14.1%, from $98.4 billion for the year ended December 31, 2023 compared to $112.3 billion for the year ended December 31, 2024, mainly due to the positive equity market in the year ended December 31, 2024.
44
Performance Fees
Approximately $23 billion, or 13% of our AUM at December 31, 2025, were in accounts with performance fee features in which we participate. Performance fees are typically shared with key employees through various contractual compensation and profit-sharing arrangements.
Year ended December 31, 2025 compared to year ended December 31, 2024: Performance fees decreased $(40.0) million, or (56.0)%, from $71.4 million for the year ended December 31, 2024 to $31.4 million for the year ended December 31, 2025, primarily due to a change in performance relative to benchmarks in certain strategies. Performance fees are variable and are contractually triggered based on investment performance results over agreed upon time periods.
Year ended December 31, 2024 compared to year ended December 31, 2023: Performance fees increased $21.0 million, or 41.7%, from $50.4 million for the year ended December 31, 2023 to $71.4 million for the year ended December 31, 2024, primarily due to strong performance relative to benchmarks in certain strategies. Performance fees are variable and are contractually triggered based on investment performance results over agreed upon time periods.
U.S. GAAP Expenses
Our U.S. GAAP expenses principally consist of:
i.compensation paid to our investment professionals and other employees, including base salary, benefits, sales-based compensation, variable compensation, Acadian LLC key employee distributions, and revaluation of key employee-owned Acadian LLC equity and profit interests;
ii.general and administrative expenses;
iii.depreciation and amortization charges; and
iv.expenses of consolidated Funds, a portion of which is attributable to the holders of non-controlling interests in consolidated Funds.
Compensation and Benefits Expense
Our most significant category of expense is compensation and benefits awarded to our employees. The following table presents the components of U.S. GAAP compensation expense for the years ended December 31, 2025, 2024 and 2023:
Years ended December 31,
Fixed compensation and benefits(1) $ 102.1 $ 97.8 $ 93.1
Acadian LLC key employee distributions(4) 21.4 9.7 5.1
Non-cash Acadian LLC key employee equity revaluations(5) 47.7 23.2 (0.1)
Total U.S. GAAP compensation and benefits expense $ 313.9 $ 265.5 $ 217.9
(1)Fixed compensation and benefits includes base salaries, payroll taxes and the cost of benefit programs provided.
45
(2)Sales-based compensation is paid to our sales and distribution teams and represents compensation earned by our sales professionals, paid over a multi-year period, related to revenue earned on new sales. Its variability is based upon the structure of sales-based compensation due on inflows of assets under management and market-based movement in both current and prior periods.
(3)Variable compensation includes the portion of earnings that is contractually allocated to Acadian LLC employees as a bonus pool, plus Hold Co bonuses. Variable compensation may be paid in the form of cash or non-cash equity or profit interests awards. We have a contractual split of performance fees between Acadian LLC employees and AAMI. Acadian LLC’s share of performance fees, which ranges between 60%-75% of the total, is allocated entirely to variable compensation. The variable compensation earned on performance fees vests over three-years and compensation expense is recognized over that service period. Hold Co variable compensation includes cash and our equity. Equity-based compensation awards typically vest over several years and are recognized as compensation expense over that service period.
Years ended December 31,
Amortization of equity-based awards 5.9 6.9 6.3
(a)For the year ended December 31, 2025, $126.7 million of variable compensation expense (of the $125.7 million above) is included within economic net income, which excludes the variable compensation associated with restructuring of $(1.0) million. For the year ended December 31, 2024, $122.8 million of variable compensation expense (of the $122.7 million above) is included within economic net income, which excludes the variable compensation associated with restructuring of $(1.0) million and costs associated with the wind-down of the MACS business in the standalone format of $0.9 million. For the year ended December 31, 2023, $104.9 million of variable compensation expense (of the $112.2 million above) is included within economic net income, which excludes the variable compensation associated with restructuring of $7.3 million.
(4)Acadian LLC key employee distributions represent the share of Acadian LLC profits after variable compensation that is attributable to key employee equity and profit interests holders, according to their ownership interests. Acadian LLC key employee distribution ratio is calculated as Acadian LLC key employee distributions divided by ENI operating earnings. Within Acadian LLC we have a tiered equity structure, where AAMI and other classes of employee equity holders are entitled to an initial proportionate preference over profits after variable compensation, structured such that before a preference threshold is reached, there would be no required key employee distributions to the tiered equity holders, whereas for profits above the threshold, the key employee distribution amount to the tiered equity holders would be calculated based on the tiered key employee ownership percentages.
(5)Non-cash Acadian LLC key employee equity revaluations represent changes in the value of Acadian LLC equity and profit interests held by key employees. These ownership interests may in certain circumstances be repurchased by Hold Co at a value based on a pre-determined fixed multiple of twelve-month earnings and as such a liability is carried on our balance sheet based on the expected cash to be paid. However, any equity or profit interests repurchased by Hold Co can be used to fund a portion of future variable compensation awards, resulting in savings in cash variable compensation that offset the negative cash effect of repurchasing the equity. The Acadian LLC equity and profit interest plans have been designed to ensure Hold Co is not required to repurchase more equity than we can reasonably recycle through variable compensation awards in any given twelve-month period.
46
Fluctuations in compensation and benefits expense for the periods presented are discussed below.
Year ended December 31, 2025 compared to year ended December 31, 2024: Compensation and benefits expense increased $48.4 million, or 18.2%, from $265.5 million for the year ended December 31, 2024 to $313.9 million for the year ended December 31, 2025. Fixed compensation and benefits increased $4.3 million, or 4.4%, from $97.8 million for the year ended December 31, 2024 to $102.1 million for the year ended December 31, 2025, primarily reflecting cost of living increases and an increase in the cost of employee benefits. Variable compensation increased $3.0 million, or 2.4%, from $122.7 million for the year ended December 31, 2024 to $125.7 million for the year ended December 31, 2025. The increase was primarily attributable to higher pre-bonus profits in the year ended December 31, 2025, partially offset by lower deferred bonus earned on performance fee revenues in the current year. The deferred nature of the bonus earned on performance fee revenues can result in compensation expense variability that is uncorrelated to current period earnings. Sales-based compensation increased $4.9 million, or 40.5%, from $12.1 million for the year ended December 31, 2024 to $17.0 million for the year ended December 31, 2025, driven by the increase in asset inflows. Acadian LLC key employee distributions increased $11.7 million, or 120.6%, from $9.7 million for the year ended December 31, 2024 to $21.4 million for the year ended December 31, 2025. Acadian LLC key employee distributions for certain tiers of equity are calculated after an earnings threshold is met, whereby no distributions are made to these equity holders when earnings are below the threshold. The change in Acadian LLC key employee distributions during the current period is driven by higher operating earnings and the leveraged nature of this distribution share. Revaluations of Acadian LLC key employee equity changed by $24.5 million in 2025, reflecting revaluations of key employee ownership interests at Acadian LLC, as the value of the equity plan liability increased $23.2 million for the year ended December 31, 2024, and increased $47.7 million for the year ended December 31, 2025. For certain tiers of Acadian LLC equity, revaluations are calculated based on earnings above a threshold. The change in the revaluation in the current period is driven by higher earnings period over period, including earnings over the threshold for certain Acadian LLC equity, as well as changes in inputs used in the valuation model, including market risk assumptions and discount rates.
Year ended December 31, 2024 compared to year ended December 31, 2023: Compensation and benefits expense increased $47.6 million, or 21.8%, from $217.9 million for the year ended December 31, 2023 to $265.5 million for the year ended December 31, 2024. Fixed compensation and benefits increased $4.7 million, or 5.0%, from $93.1 million for the year ended December 31, 2023 to $97.8 million for the year ended December 31, 2024, primarily reflecting the cost of new hires supporting our growth initiatives and cost of living increases, partially offset by cost savings realized from restructuring at Acadian LLC in late 2023. Variable compensation increased $10.5 million, or 9.4%, from $112.2 million for the year ended December 31, 2023 to $122.7 million for the year ended December 31, 2024. The increase was primarily attributable to higher pre-bonus profits in the year ended December 31, 2024, partially offset by lower restructuring expenses. Sales-based compensation increased $4.5 million, or 59.2%, from $7.6 million for the year ended December 31, 2023 to $12.1 million for the year ended December 31, 2024, driven by higher gross sales in 2024. Acadian LLC key employee distributions increased $4.6 million, or 90.2%, from $5.1 million for the year ended December 31, 2023 to $9.7 million for the year ended December 31, 2024. Acadian LLC key employee distributions for certain tiers of equity are calculated after an earnings threshold is met, whereby no distributions are made to these equity holders when earnings are below the threshold. The change in Acadian LLC key employee distributions during the year ended December 31, 2024 was driven by higher operating earnings and the leveraged nature of this distribution share. Revaluations of Acadian LLC key employee equity changed by $23.3 million, reflecting revaluations of key employee ownership interests at Acadian LLC, as the value of the equity plan liability decreased $(0.1) million for the year ended December 31, 2023, and increased $23.2 million for the year ended December 31, 2024. For certain tiers of Acadian LLC equity, revaluations are calculated based on earnings above a threshold. The change in the revaluation in the year ended December 31, 2024 was driven by higher earnings period over period, including earnings over the threshold for certain Acadian LLC equity.
47
General and Administrative Expense
Year ended December 31, 2025 compared to year ended December 31, 2024: General and administrative expense increased $6.8 million, or 8.0%, from $85.2 million for the year ended December 31, 2024 to $92.0 million for the year ended December 31, 2025. The increase was primarily due to higher system, recruiting, portfolio administrative, and consulting costs, partially offset by the impact of foreign currency changes.
Year ended December 31, 2024 compared to year ended December 31, 2023: General and administrative expense increased $2.6 million, or 3.1%, from $82.6 million for the year ended December 31, 2023 to $85.2 million for the year ended December 31, 2024. The increase was primarily due to higher systems, outside services and portfolio administrative costs, our continued investment in growth initiatives and capabilities, partially offset by lower consultant costs.
Depreciation and Amortization Expense
Year ended December 31, 2025 compared to year ended December 31, 2024: Depreciation and amortization expense decreased $(1.9) million, or (10.3)%, from $18.5 million for the year ended December 31, 2024 to $16.6 million for the year ended December 31, 2025. The decrease was primarily attributable to the effect of certain software becoming fully depreciated.
Year ended December 31, 2024 compared to year ended December 31, 2023: Depreciation and amortization expense increased $1.2 million, or 6.9%, from $17.3 million for the year ended December 31, 2023 to $18.5 million for the year ended December 31, 2024. The increase was primarily attributable to additional software and technology investments in the business.
