&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We derive a substantial portion of our revenue from a limited number of investment strategies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Investments in non-U.S. markets and in securities of non-U.S. companies 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our expenses are subject to fluctuations that could materially impact our results of operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our outstanding indebtedness may impact our business and may restrict our growth and results of operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

**PART I**

**Item 1.&nbsp;&nbsp;&nbsp;&nbsp;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.&nbsp;&nbsp;&nbsp;&nbsp;***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.&nbsp;&nbsp;&nbsp;&nbsp;***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.***&nbsp;&nbsp;&nbsp;&nbsp;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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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.

**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.

**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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the investment performance records of our strategies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the breadth of active investment strategies and vehicle options that we offer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the alignment of our investment strategies to the current market conditions and investment preferences and needs of potential clients;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the quality, depth, and reputation of the investment teams that execute our strategies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the continuity of our investment and distribution teams;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the caliber of service we provide our clients; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

------

**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

------

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.

------

***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 our business 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.

------

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.

------

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. Our techniques 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.

------

***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.

------

***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.

------

***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.

------

***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.

------

***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

------

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.

------

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.

------

***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.

------

***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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• public health emergencies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the announcement of mergers, acquisitions, dispositions or new products or services by us or others in our industry;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

------

***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.

**Item 1B.&nbsp;&nbsp;&nbsp;&nbsp;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.&nbsp;&nbsp;&nbsp;&nbsp;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.

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.&nbsp;&nbsp;&nbsp;&nbsp;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.

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• 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.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• 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.

------

**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.

**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."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)U.S. GAAP operating margin equals operating income divided by total revenue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)Economic net income is a non-GAAP measure we use to evaluate the performance of our business. For a reconciliation to U.S. GAAP financial information and a further discussion of economic net income refer to "Non-GAAP Supplemental Performance Measure — Economic Net Income and Segment Analysis."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)Excludes severance-related items of $(1.0) million for the year ended December 31, 2025. Excludes severance-related items of $(1.0) million, costs associated with the transfer of an insurance policy from our former parent of $1.3 million, and costs associated with the wind-down of the Multi-Asset Class Strategy, or "MACS" business in the standalone format of $1.3 million for the year ended December 31, 2024. Excludes severance costs of $7.3 million, legal-related restructuring costs at the Hold Co of $0.9 million and costs associated with the transfer of an insurance policy from our former parent of $1.3 million for the year ended December 31, 2023.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4)ENI revenue is the ENI measure which corresponds to U.S. GAAP revenue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5)Pre-tax economic net income is the ENI measure which corresponds to U.S. GAAP pre-tax income attributable to controlling interests.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6)ENI operating margin is a non-GAAP efficiency measure, calculated based on ENI operating earnings divided by ENI revenue. ENI operating earnings is calculated as ENI revenue, less ENI operating expense, less ENI variable compensation. The ENI operating margin is most directly comparable to our U.S. GAAP operating margin (excluding the effect of consolidated Funds).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7)Economic net income is the non-GAAP measure which is most directly comparable to U.S. GAAP net income attributable to controlling interests.

**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.

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.

------

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.

**U.S. GAAP Revenues**

Our U.S. GAAP revenues principally consist of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.management fees earned based on our overall weighted average fee rate charged to our clients and the level of assets under management;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.performance fees earned when our investment performance over agreed time periods for certain clients has differed from predetermined hurdles; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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:*&nbsp;&nbsp;&nbsp;&nbsp;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:*&nbsp;&nbsp;&nbsp;&nbsp;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.

------

***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:*&nbsp;&nbsp;&nbsp;&nbsp;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:*&nbsp;&nbsp;&nbsp;&nbsp;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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.general and administrative expenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii.depreciation and amortization charges; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;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,** | **Years ended December 31,** | **Years ended December 31,** |
| **($ in millions)** | **2025** | **2024** | **2023** |
| Fixed compensation and benefits<sup>(1)</sup> | $102.1 | $97.8 | $93.1 |
| Sales-based compensation<sup>(2)</sup> | 17.0 | 12.1 | 7.6 |
| Variable compensation<sup>(3)</sup> | 125.7 | 122.7 | 112.2 |
| Acadian LLC key employee distributions<sup>(4)</sup> | 21.4 | 9.7 | 5.1 |
| Non-cash Acadian LLC key employee equity revaluations<sup>(5)</sup> | 47.7 | 23.2 | (0.1) |
| **Total U.S. GAAP compensation and benefits expense** | $**313.9** | $**265.5** | $**217.9** |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)Fixed compensation and benefits includes base salaries, payroll taxes and the cost of benefit programs provided.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(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.

------

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:*&nbsp;&nbsp;&nbsp;&nbsp;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.

***General and Administrative Expense***

*Year ended December 31, 2025 compared to year ended December 31, 2024:*&nbsp;&nbsp;&nbsp;&nbsp;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:*&nbsp;&nbsp;&nbsp;&nbsp;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:*&nbsp;&nbsp;&nbsp;&nbsp;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:*&nbsp;&nbsp;&nbsp;&nbsp;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.

**U.S. GAAP Income Tax Expense**

Our effective tax rate has been impacted by state and local tax obligations, changes in liabilities for uncertain tax positions, tax effects of stock-based compensation, limitations on executive compensation, and the mix of income earned in the United States versus foreign jurisdictions. Our effective tax rate could be impacted in the future by these items as well as further changes in tax laws and regulations in jurisdictions in which we operate.

The American Rescue Plan Act of 2021 ("ARPA"), among other things, includes provisions to expand the IRC Section 162(m) disallowance for deduction of certain compensation paid by publicly held corporations. Effective for tax years starting after December 31, 2026, ARPA expands the limitations to cover the next five most highly compensated employees. On July 4, 2025, H.R.1, commonly referred to as the One Big Beautiful Bill Act (the "OBBBA"), was enacted in the United States. The OBBBA includes a broad range of tax reform provisions, including extensions and modifications of certain provisions of the Tax Cuts and Jobs Act, with various effective dates beginning in 2025 through 2027. The OBBBA includes amendments to Internal Revenue Code Section 162(m) that expand the scope of entities and employees considered in determining "covered employees" subject to the limitation on the deductibility of compensation. The OBBBA and ARPA did not have a material impact to the income tax expense during the current period. The Company continues to evaluate the impact of IRC Section 162(m) amendments under the OBBBA and ARPA on future periods, including potential changes in covered employees, compensation structures and related deferred tax balances as additional guidance becomes available.

*Year ended December 31, 2025 compared to year ended December 31, 2024:*&nbsp;&nbsp;&nbsp;&nbsp;Income tax expense decreased $(2.3) million, from $38.9 million for the year ended December 31, 2024 to $36.6 million for the year ended December 31, 2025. The decrease in income tax expense is primarily related to the decrease in pre-tax income from controlling interests for the year ended December 31, 2025.

*Year ended December 31, 2024 compared to year ended December 31, 2023:*&nbsp;&nbsp;&nbsp;&nbsp;Income tax expense increased $9.5 million, from $29.4 million for the year ended December 31, 2023 to $38.9 million for the year ended December 31, 2024. The increase in income tax expense is primarily related to the increase in pre-tax income from controlling interests for the year ended December 31, 2024.

**U.S. GAAP Consolidated Funds**

The net income or loss of all consolidated Funds, excluding any income or loss attributable to seed capital or co-investments we make in the Funds, is included in non-controlling interests in our Consolidated Financial Statements and is not included in net income attributable to controlling interests or in management fees.

*Year ended December 31, 2025 compared to year ended December 31, 2024:* Consolidated Funds' revenue increased $11.5 million, from $3.1 million for the year ended December 31, 2024 to $14.6 million for the year ended December 31, 2025. Consolidated Funds' expense increased $8.2 million, from $0.9 million for the year ended December 31, 2024 to $9.1 million for the year ended December 31, 2025. These movements relate to the underlying activity of our consolidated Funds.

*Year ended December 31, 2024 compared to year ended December 31, 2023:* Consolidated Funds' revenue increased $0.1 million from $3.0 million for the year ended December 31, 2023 to $3.1 million for the year ended December 31, 2024. Consolidated Funds' expense decreased $(1.9) million from $2.8 million for the year ended December 31, 2023 to $0.9 million for the year ended December 31, 2024. These movements relate to the underlying activity of our consolidated Funds.

**Non-GAAP Supplemental Performance Measure—Economic Net Income and Segment Analysis**

As supplemental information, we provide a non-GAAP performance measure that we refer to as economic net income, or ENI, which represents our management's view of the underlying economic earnings generated by us. We define economic net income as ENI revenue less (i) ENI operating expenses, (ii) variable compensation, (iii) key employee distributions, (iv) net interest and (v) taxes, each as further discussed in this section. ENI adjustments to U.S. GAAP include both reclassifications of U.S. GAAP revenue and expense items, as well as adjustments to U.S. GAAP results, primarily to exclude non-cash, non-economic expenses, or to reflect cash benefits not recognized under U.S. GAAP.

ENI is an important measure to investors because it is used by us to make resource allocation decisions, determine appropriate levels of investment or dividend payout, manage balance sheet leverage, determine variable compensation and equity distributions, and incentivize management. It is also an important measure because it assists management in evaluating our operating performance and is presented in a way that most closely reflects the key elements of our profit share operating model with Acadian LLC. For a further discussion of how we use ENI and why ENI is useful to investors, see "—Overview—How We Measure Performance."

To calculate economic net income, we re-categorize certain line items on our Consolidated Statements of Operations to reflect the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We exclude the effect of Funds' consolidation by removing the portion of Fund revenues, expenses and investment return which were not attributable to our stockholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We include within management fee revenue any fees paid to the Company by consolidated Funds.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We treat sales-based compensation as a general and administrative expense, rather than part of fixed compensation and benefits.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We identify separately from operating expenses variable compensation and Acadian LLC key employee distributions, which represent Acadian LLC earnings shared with key employees.

------

We also make the following adjustments to U.S. GAAP results to more closely reflect our economic results:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.We exclude non-cash expenses representing 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 trailing earnings and as such this value is carried on our balance sheet as a liability. Non-cash movements in the value of this liability are treated as compensation expense under U.S. GAAP. 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. Our equity and profit interest plans have been designed to ensure Hold Co is never required to repurchase more equity than we can reasonably recycle through variable compensation awards in any given twelve-month period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;ii.We exclude non-cash amortization or impairment expenses related to acquired goodwill and other intangibles as these are non-cash charges that do not result in an outflow of tangible economic benefits from the business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iii.We exclude capital transaction costs, including the costs of raising debt or equity, gains or losses realized as a result of redeeming debt or equity and direct incremental costs associated with acquisitions of businesses or assets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;iv.We exclude seed capital and co-investment gains, losses, and related financing costs. The net returns on these investments are considered and presented separately from ENI because ENI is primarily a measure of our earnings from managing client assets, which therefore differs from earnings generated by our investments, which can be variable from period to period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;v.We include cash tax benefits associated with deductions allowed for acquired intangibles and goodwill that may not be recognized or have timing differences compared to U.S. GAAP.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;vi.We exclude the results of discontinued operations attributable to controlling interests since they are not part of our ongoing business and restructuring costs incurred in continuing operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;vii.We exclude deferred tax resulting from changes in tax law and expiration of statutes, adjustments for uncertain tax positions, deferred tax attributable to intangible assets and other unusual items not related to current operating results to reflect ENI tax normalization.

We also adjust our income tax expense to reflect any tax impact of our ENI adjustments.

**Limitations of Economic Net Income**

Economic net income is the key measure our management uses to evaluate the financial performance of, and make operational decisions for, our business. Economic net income is not audited and is not a substitute for net income or other performance measures that are derived in accordance with U.S. GAAP. Furthermore, our calculation of economic net income may differ from similarly titled measures provided by other companies.

Because the calculation of economic net income excludes certain ongoing expenses, including amortization expense and certain compensation costs, it has certain material limitations and should not be viewed in isolation or as a substitute for U.S. GAAP measures of earnings.

**ENI Operating Expenses**

The largest difference between U.S. GAAP operating expense and ENI operating expense relates to compensation. As shown in the following reconciliation, we exclude the impact of key employee equity revaluations. Variable compensation and Acadian LLC key employee distributions are also segregated out of U.S. GAAP operating expense in order to align with the manner in which these items are contractually calculated.

**Key Non-GAAP Operating Metrics**

The following table shows our key non-GAAP operating metrics for the years ended December 31, 2025, 2024 and 2023. We present these metrics because they are the measures our management uses to evaluate the profitability of our business and are useful to investors because they represent the key drivers and measures of economic performance within our business model. Please see the footnotes below for an explanation of each ratio, its usefulness in measuring the economics and operating performance of our business, and a reference to the most closely related U.S. GAAP measure:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)The year ended December 31, 2025 includes $(1.0) million of severance-related items. The year ended December 31, 2024 includes $(1.0) million of severance-related items, $1.3 million associated with the transfer of an insurance policy from our former parent and $1.3 million of costs associated with the wind-down of the MACS business in the standalone format. The year ended December 31, 2023 includes $7.3 million of severance costs, $0.9 million of legal-related restructuring costs at the Hold Co and $1.3 million associated with the transfer of an insurance policy from our former parent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)The year ended December 31, 2025 excludes $(1.0) million of severance-related items that are included within restructuring costs. The year ended December 31, 2024 excludes $(1.0) million of severance-related items that is included within restructuring costs and $0.9 million of costs associated with the wind-down of the MACS business in the standalone format that is included within restructuring costs. The year ended December 31, 2023 excludes $7.3 million of severance costs that are included within restructuring costs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)The ENI operating margin, which is calculated before Acadian LLC key employee distributions, is used by management and is useful to investors to evaluate the overall operating margin of the business. The ENI operating margin is most comparable to our U.S. GAAP operating margin. Our U.S. GAAP operating margin, excluding the effect of consolidated Funds, was 23.1% for the year ended December 31, 2025, 26.5% for the year ended December 31, 2024 and 25.0% for the year ended December 31, 2023.

The ENI operating margin is important because it gives investors an understanding of the profitability of the total business relative to revenue, irrespective of the ownership position which we have in Acadian LLC. Management and investors use this ratio when comparing our profitability relative to our peer group and evaluating our ability to manage the cost structure and profitability of our business under different operating environments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)ENI management fee revenue corresponds to U.S. GAAP management fee revenue.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4)The ENI operating expense ratio is used by management and is useful to investors to evaluate the level of operating expense as measured against our recurring management fee revenue. We have provided this ratio since many operating expenses, including fixed compensation and benefits and general and administrative expense, are generally linked to the overall size of the business. We track this ratio as a key measure of scale economies because in our profit-sharing economic model, scale benefits both the Acadian LLC employees and our stockholders. The ENI operating expense ratio is most comparable to the U.S. GAAP operating expense / management fee revenue ratio.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5)ENI earnings before variable compensation is calculated as ENI revenue, less ENI operating expense.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6)The ENI variable compensation ratio is used by management and is useful to investors to evaluate consolidated variable compensation as measured against our ENI earnings before variable compensation. Variable compensation is primarily comprised of a contractual percentage of Acadian LLC's ENI earnings before variable compensation and may be paid in the form of cash or non-cash Acadian LLC equity or profit interests. Hold Co variable compensation includes cash and AAMI equity. Non-cash variable compensation awards typically vest over several years and are recognized as compensation expense over that service period. The variable compensation ratio is calculated as variable compensation divided by ENI earnings before variable compensation. The ENI variable compensation ratio is most comparable to the U.S. GAAP variable compensation ratio.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7)The ENI Acadian LLC key employee distribution ratio is used by management and is useful to investors to evaluate Acadian LLC key employee distributions as measured against our ENI operating earnings. Acadian LLC key employee distributions represent the share of profits after variable compensation that is attributable to Acadian LLC key employee equity and profit interests holders, according to their ownership interests. It 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. The ENI Acadian LLC key employee distributions ratio is most comparable to the U.S. GAAP Acadian LLC key employee distributions ratio.

**Segment Analysis**

We operate our business through the following reportable segment:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• 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.

The corporate holding company ("Hold Co") is included within the *Unallocated Corporate expense* category. The Hold Co expenses are not allocated to the Company's business segment, but the CODM does consider the cost structure of the corporate head office when evaluating the financial performance of our segment. The CODM is the Company's Chief Executive Officer.

The primary measure used by the CODM in measuring performance and allocating resources to the segment is ENI. ENI is used to make resource allocation decisions, determine appropriate levels of investment or dividend payout, manage balance sheet leverage, determine variable compensation and equity distributions, and incentivize management. We define economic net income for the segment as ENI revenue less ENI operating expenses. The ENI adjustments to U.S. GAAP include both reclassifications of U.S. GAAP revenue and expense items, as well as adjustments to U.S. GAAP results, primarily to exclude non-cash, non-economic expenses recognized under U.S. GAAP.

ENI revenue includes management fees, performance fees and other revenue under U.S. GAAP, adjusted to include management fees paid to the Company by consolidated Funds.

Significant segment ENI expenses include fixed compensation and benefits, variable compensation, Acadian LLC key employee distributions, depreciation and amortization, and general and administrative expense under U.S. GAAP, adjusted to exclude non-cash expenses representing changes in the value of Acadian LLC equity and profit interests held by Acadian LLC key employees, capital transaction costs, and restructuring costs.

ENI segment results are also adjusted to exclude consolidated Funds' revenues, consolidated Funds' expenses and investment return recorded under U.S. GAAP.

Refer to the reconciliations of U.S. GAAP revenue to ENI revenue, U.S. GAAP Operating expense to ENI Operating expense, variable compensation and Acadian LLC key employee distributions disclosed previously within this section.

Quant & Solutions ENI variable compensation expense is based on contractual percentage of earnings before variable compensation and also includes a formulaic split of performance fee revenue that gets deferred and recognized as variable compensation expense over a three-year vesting period. The deferred nature of the bonus earned on performance fee revenues can result in compensation expense variability that is uncorrelated to current period earnings. Quant & Solutions ENI variable compensation expense increased 17.3%, primarily as a result of higher earnings before variable compensation. 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 is driven by higher operating earnings and the leveraged nature of this distribution share.

*Year ended December 31, 2025 compared to year ended December 31, 2024:* Unallocated corporate expense decreased $(1.1) million, or (5.7)%, from $19.4 million for the year ended December 31, 2024 to $18.3 million for the year ended December 31, 2025. The decrease was driven by lower general and administrative expense, slightly offset by higher compensation and benefits expense.

*Year ended December 31, 2024 compared to year ended December 31, 2023:* Unallocated corporate expenses increased $0.3 million, or 1.6%, from $19.1 million for the year ended December 31, 2023 to $19.4 million for the year ended December 31, 2024. The increase was driven by higher compensation and benefits expense due to cost of living and payroll tax increases, partially offset by lower general and administrative expenses due to a decrease in legal costs.

**Capital Resources and Liquidity**

**Cash Flows**

The following table summarizes certain key financial data relating to cash flows. All amounts presented exclude consolidated Funds:

| Operating activities | $129.8 | $108.9 | $77.7 |
| Investing activities | 5.3 | (50.1) | (31.4) |
| Financing activities | (129.2) | (110.4) | (8.1) |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)Excludes consolidated Funds.

Our most significant uses of cash include repayment of third-party borrowings and revolving credit facility, share repurchases, third-party interest payments, tax payments, seed capital investments, dividends and compensation and general and administrative expenses.

***Comparison for the Years Ended December 31, 2025, 2024 and 2023***

Net cash provided by operating activities excluding consolidated Funds increased $20.9 million, from net cash provided of $108.9 million during the year ended December 31, 2024 to net cash provided of $129.8 million during the year ended December 31, 2025. The increase was driven by changes in net income offset by changes in operating asset and liabilities period-over-period, including changes in investment advisory fees receivable and accrued incentive compensation balances.

Net cash provided by operating activities excluding consolidated Funds increased $31.2 million, from net cash provided of $77.7 million during the year ended December 31, 2023 to net cash provided of $108.9 million during the year ended December 31, 2024. The increase was driven by changes in net income offset by changes in operating asset and liabilities period-over-period.

Net cash provided by (used in) investing activities, excluding consolidated Funds, was $5.3 million, $(50.1) million and $(31.4) million for the years ended December 31, 2025, 2024 and 2023, respectively. Fluctuations are driven by the timing of investments and redemptions of seed capital. Net cash received from (used in) the sale and (purchase) of investments was $17.2 million, $(40.2) million and $(17.6) million for the years ended December 31, 2025, 2024 and 2023, respectively.

------

Net cash used in financing activities, excluding consolidated Funds, consists of share repurchases, third-party borrowings, payments made to OM plc, withholding tax payments on stock option exercises and dividend payments. Net cash used in financing activities was $(129.2) million, $(110.4) million and $(8.1) million for the years ended December 31, 2025, 2024 and 2023, respectively. Share repurchases, revolving credit facility borrowing activity and third party borrowing activity were the drivers of the changes in financing activities year over year. We paid $(48.8) million for share repurchases in 2025 compared to $(96.7) million in 2024 and $(3.3) million in 2023. In 2025, we paid down net $(76.1) million against third-party and revolving credit facility borrowings compared to $0.0 million in 2024 and 2023.

**Working Capital and Long-Term Debt**

The following table summarizes certain key financial data relating to our capital resources and liquid net assets. All amounts presented exclude the non-controlling interest portion of consolidated Funds:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)Includes income taxes receivable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)Includes the short-term portion of our lease liability and accrued income taxes payable. Excluded from other short-term liabilities for each of the years presented is an income tax reserve relating to net operating losses that does not represent a current obligation of the Company. Puts related to Acadian LLC equity and profits interests are also excluded on a short-term basis because they are funded through recycling.

Working capital is defined as current assets less current liabilities, excluding the non-controlling interest portion of consolidated Funds. Our net working capital has been positive over the past several years and was $196.7 million at December 31, 2025. Our most significant current liabilities have been accounts payable, accrued compensation expense and the short-term portion of our third-party debt. Accrued compensation expense has primarily consisted of variable compensation accruals made throughout the year based on contractual arrangements. Our cash management practices generally require that working capital be maintained at an appropriate level to meet short-term operational needs at both Acadian LLC and Hold Co. Periodic distributions of Acadian LLC earnings to Hold Co and Acadian LLC key employee equity holders are made according to our distribution policies, with Hold Co having the ability to access surplus cash at Acadian LLC as necessary during interim periods.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)On October 28, 2025, Acadian LLC's $140 million revolving credit facility was terminated and replaced with a new $175 million revolving credit facility.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)On December 1, 2025, we completed the full redemption of the $275 million aggregate principal amount outstanding of our 4.80% Senior Notes due 2026. As a result of this transaction, we recorded $(1.4) million of loss on extinguishment of debt within the Consolidated Statements of Operations for the year ended December 31, 2025.

**The Delayed Draw Term Loan Credit Agreement and Revolving Credit Agreement**

On October 28, 2025 (the "Closing Date), Acadian LLC entered into a Delayed Draw Term Loan Credit Agreement among Acadian LLC, the Lenders from time to time party thereto, and Bank of America, N.A. ("Bank of America"), as the Administrative Agent (the "DDTL Credit Agreement") and a Revolving Credit Agreement among Acadian LLC, the Lenders from time to time party thereto, Bank of America, as the Administrative Agent and a L/C Issuer and the other L/C Issuers from time to time party thereto (the "Revolving Credit Agreement").

The DDTL Credit Agreement provides for a delayed draw term loan facility in an aggregate principal amount, as of the Closing Date, of up to $200 million (the "Term Facility"). The term loans mature on October 28, 2028. Subject to certain conditions, Acadian LLC may increase the size of the Term Facility to an aggregate maximum principal amount of $275 million. None of the lenders under the Term Facility are obligated to provide such additional commitments to Acadian LLC.

Loans under the DDTL Credit Agreement bear interest, at Acadian LLC's option, at a rate per annum equal to (i) Term SOFR for the applicable interest period plus an applicable margin equal to a range of 1.5% to 2.0% depending on Acadian LLC's consolidated leverage ratio or (ii) an alternate base rate (defined as a rate equal to the highest of (i) the Federal Funds Rate plus 0.5%, (ii) Bank of America's published "prime rate" and (iii) Term SOFR plus 1.0%) plus an applicable margin equal to a range of 0.5% to 1.0% depending on Acadian LLC's consolidated leverage ratio.

Financial covenants under the Term Facility include the quarterly maintenance by the Acadian LLC of (i) a maximum Consolidated Net Leverage Ratio (as defined in the DDTL Credit Agreement) of not greater than 2.5x and (ii) a minimum Consolidated Interest Coverage Ratio (calculated as the ratio of Acadian LLC Consolidated EBITDA (as defined in the DDTL Credit Agreement), divided by Acadian LLC interest expense for the four consecutive

------

fiscal quarters ended on or immediately prior to the date of determination) of not less than 4.0x. For purposes of calculating the Consolidated Net Leverage Ratio, the DDTL Credit Agreement refers to Consolidated Funded Indebtedness (as defined in the DDTL Credit Agreement) minus unrestricted cash at Acadian LLC. At December 31, 2025, Acadian LLC's Leverage Ratio was 0.6x and Acadian LLC's Interest Coverage Ratio was 85.7x.

The Revolving Credit Agreement provides for senior unsecured revolving credit commitments as of the Closing Date in an aggregate principal amount, as of the Closing Date, of up to $175 million (the "Revolving Facility"). The revolving commitments mature on October 28, 2028. Subject to certain conditions, Acadian LLC may increase the size of the Revolving Facility to an aggregate maximum principal amount of $275 million, which may be established in the form of revolving commitments or term loan commitments. None of the lenders under the Revolving Facility are obligated to provide such additional commitments to Acadian LLC.

Borrowings under the Revolving Credit Agreement bear interest, at Acadian LLC's option, at a rate per annum equal to (i) Term SOFR (as defined in the Revolving Credit Agreement) for the applicable interest period plus an applicable margin equal to a range of 1.5% to 2.0% depending on Acadian LLC's Consolidated Leverage Ratio (as defined in the Revolving Credit Agreement) or (ii) an alternate base rate (defined as a rate equal to the highest of (i) the Federal Funds Rate plus 0.5%, (ii) Bank of America's published "prime rate" and (iii) Term SOFR plus 1.0%) plus an applicable margin equal to a range of 0.5% to 1.0% depending on Acadian LLC's Consolidated Leverage Ratio. The Company is required to pay a commitment fee at a per annum rate ranging from 0.25% to 0.375%, with such amount based on Acadian LLC's Consolidated Leverage Ratio on the daily undrawn amount of the revolving commitments, and customary letter of credit participation and fronting fees.

As of December 31, 2025, Acadian LLC had unused lines of credit of $172.5 million comprised of undrawn commitments on the Revolving Credit Facility of $175 million less a $2.5 million letter of credit with Bank of America related to one of the Acadian LLC's current office spaces.

As of December 31, 2025, we were in compliance with the required covenants related to borrowings and debt facilities.

**Other Compensation Liabilities**

Other compensation liabilities principally consist of cash-settled Acadian LLC equity and profit interests liabilities held by key employees, and voluntary deferred compensation plans. The following table summarizes our other compensation liabilities:

---

| | | |
|:---|:---|:---|
| | **Years ended December 31,** | **Years ended December 31,** |
| **($ in millions)** | **2025** | **2024** |
| Share-based payments liability | $37.0 | $25.4 |
| Profit interests liability | 54.0 | 18.7 |
| &nbsp;&nbsp;&nbsp;Employee equity | 91.0 | 44.1 |
| Voluntary deferral plan liability | 37.9 | 48.4 |
| &nbsp;&nbsp;&nbsp;**Total** | $**128.9** | $**92.5** |

---

------

Share-based payments liability represents the value of Acadian LLC key employee-owned equity that may under certain circumstances be repurchased by us that is considered an equity award under U.S. GAAP based on the terms and conditions attached to these interests. Acadian LLC profit interests liability represents the value of Acadian LLC key employee-owned equity that may under certain circumstances be repurchased by us that is not considered an equity award under U.S. GAAP, but rather a form of compensation arrangement, based on the terms and conditions attached to these interests. Our obligation in any given period in respect of funding these potential repurchases of Acadian LLC equity is limited to only that portion that may be put to us by Acadian LLC key employees, which is typically capped annually under the terms of these arrangements such that we are not required to repurchase more than we can reasonably recycle by re-granting the interests in lieu of cash variable compensation owed to Acadian LLC key employees.

Certain of our employees are eligible to participate in our voluntary deferral plan, or VDP, which provides our senior personnel the opportunity to voluntarily defer a portion of their compensation. There is a voluntary deferral plan investment balance included in investments on the Consolidated Balance Sheets that corresponds to this deferral liability.

Additionally, we have recorded accrued incentive compensation of $129.9 million and $119.6 million on the Consolidated Balance Sheets as of December 31, 2025 and 2024, respectively. Included within the accrued incentive compensation balance is the vested portion of our deferred compensation pool. The majority of the deferred compensation pool is based on a contractual percentage of Acadian LLC performance fee revenues and post-bonus profits, and is subject to a three-year vesting period. Compensation expense is recognized over the requisite service period. Unamortized compensation expense related to the unvested portion of the deferred compensation pool of $23.5 million and $9.7 million is expected to be recognized in the years ending December 31, 2026 and 2027, respectively.

For additional discussion of our compensation programs, please refer to the compensation discussions contained within our definitive proxy statement for our 2026 annual meeting of stockholders incorporated herein by reference.

**&nbsp;&nbsp;&nbsp;&nbsp;Supplemental Liquidity Measure—Adjusted EBITDA**

As supplemental information, we provide information regarding Adjusted EBITDA, which we define as economic net income before net interest, income taxes, depreciation and amortization. Adjusted EBITDA is a non-GAAP liquidity measure that we provide in addition to, but not as a substitute for, cash flows from operating activities. It should be noted that our calculation of Adjusted EBITDA may not be consistent with Adjusted EBITDA as calculated by other companies. We believe Adjusted EBITDA is a useful liquidity metric because it indicates our ability to make further investments in our business, service debt and meet working capital requirements.

The following table reconciles our U.S. GAAP net income attributable to controlling interests to EBITDA to Adjusted EBITDA to economic net income for the years ended December 31, 2025, 2024 and 2023:

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)Included in restructuring for the year ended December 31, 2025 are $(1.0) million of severance-related items. Included in restructuring for the year ended December 31, 2024 are $(1.0) million of severance-related items, $0.9 million costs associated with the wind-down of the MACS business in the standalone format and $1.3 million costs associated with the transfer of an insurance policy from our former parent. Included in restructuring for the year ended December 31, 2023 are $7.3 million of severance costs, $0.9 million of legal-related restructuring costs at the Hold Co and $1.3 million of costs associated with the transfer of an insurance policy from our former parent.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)Includes non-cash equity-based award amortization expense.

For a full discussion regarding the items excluded from Adjusted EBITDA above and the calculation of economic net income, refer to "—Non-GAAP Supplemental Performance Measure—Economic Net Income and Segment Analysis."

***Limitations of Adjusted EBITDA***

As a non-GAAP, unaudited liquidity measure and derivation of EBITDA, Adjusted EBITDA has certain material limitations. It does not include cash costs associated with capital transactions and excludes certain U.S. GAAP expenses that fall outside the definition of EBITDA. Each of these categories of expense represents costs to us of doing business, and therefore any measure that excludes any or all of these categories of expense has material limitations.

**Future Capital Needs**

We believe that our available cash and cash equivalents to be generated from operations, supplemented by short-term and long-term financing, as necessary, will be sufficient to fund current operations and capital requirements for at least the next twelve months, as well as our day-to-day operations and future investment requirements. Our ability to secure short-term and long-term financing in the future will depend on several factors, including our future profitability, our relative levels of debt and equity and the overall condition of the credit markets.

------

**Commitments, Contingencies and Off-Balance Sheet Obligations**

***Indemnifications***

In the normal course of business, we occasionally enter into contracts that contain a variety of representations and warranties and which provide general indemnifications. Our maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against us that have not yet occurred.

***Off-Balance Sheet Obligations***

Off-balance sheet arrangements, as defined by the SEC, include certain contractual arrangements pursuant to which a company has an obligation, such as certain contingent obligations, certain guarantee contracts, retained or contingent interests in assets transferred to an unconsolidated entity, certain derivative instruments classified as equity or material variable interests in unconsolidated entities that provide financing, liquidity, market risk or credit risk support. Disclosure is required for any off-balance sheet arrangements that have, or are reasonably likely to have, a material current or future effect on our financial condition, results of operations, liquidity or capital resources. We generally do not enter into off-balance sheet arrangements, other than those described in "Contractual Obligations" as well as Note 5 and Note 14 to our Consolidated Financial Statements included in Item 8 herein, "Variable Interest Entities" and "Commitments and Contingencies", respectively.

***Contractual Obligations***

We have material future cash requirements from contractual and other obligations relating primarily to third party borrowings, operating lease obligations, and equity and profits interests repurchase obligations.

As of December 31, 2025, we had third party borrowing obligations totaling $200.0 million. This balance consists of the entire principal amount of our Delayed Draw Term Loan, which will become due October 28, 2028. See Note 12 to the Consolidated Financial Statements for additional disclosures pertaining to our third party borrowings.

As of December 31, 2025, we had operating lease payment obligations of $69.8 million. See Note 7 to the Consolidated Financial Statements for a summary of future maturities and additional disclosures pertaining to our operating lease obligations.

As of December 31, 2025, we had contractual obligations with respect to the funding of Acadian LLC equity and profits interests repurchases. Our actual funding of these potential repurchases of Acadian LLC equity and profits interests is limited to only that portion that may be put to us by Acadian LLC key employees or that we decide to call to facilitate succession planning at Acadian LLC, which is typically capped annually such that we do not repurchase more than we can reasonably recycle by re-granting the interests in lieu of cash variable compensation owed to Acadian LLC key employees. Any equity or profits interests repurchased by us are used to fund a portion of variable compensation awards resulting in savings in cash variable compensation that offset the negative cash effect of repurchasing the equity. We expect to pay $2.9 million in the next 12 months for these obligations. See Note 11 to the Consolidated Financial Statements for additional information about the Company's equity and profit interest compensation obligations. Historically, repurchases of Acadian LLC equity and profits interests have been funded entirely by the variable compensation pool, resulting in a neutral impact to our cash position.

------

**Critical Accounting Policies and Estimates**

Our significant accounting policies are disclosed in Item 8, Financial Statements and Supplementary Data - Note 2, "Significant Accounting Policies." The accounting policies and estimates that we believe are the most critical to an understanding of our results of operations and financial condition are those that require complex management judgment regarding matters that are highly uncertain at the time policies were applied and estimates were made. These accounting policies and estimates are discussed below; however, the additional accounting policy detail in the footnote previously referenced is important to the discussion of each of the topics. Different estimates reasonably could have been used in the current period that would have had a material effect on these Consolidated Financial Statements, and changes in these estimates are likely to occur from period-to-period in the future.

**Share-based compensation plans**

We recognize the cost of all share-based payments to directors, senior management and employees, including grants of restricted stock and stock options, as compensation expense in the Consolidated Statements of Operations over the respective vesting periods.

Awards made under our equity plans are accounted for as equity-settled, and the grant date fair value is recognized as compensation expense over the requisite service period, with a corresponding contribution to additional paid-in capital. Valuation of restricted stock awards ("RSAs") and restricted stock units ("RSUs") is determined based on our closing share price as quoted on the New York Stock Exchange on the measurement date. For RSU awards with a performance vesting condition, grant date fair value is determined based on our closing share price as quoted on the New York Stock Exchange on the measurement date, and compensation expense is adjusted each period to reflect the probability of achievement of the performance condition throughout the vesting period. For stock options and RSU awards with a market vesting condition, a Monte-Carlo simulation model is used to determine the fair value. Key inputs for the model include: assumed reinvestment of dividends, risk-free interest rate and expected volatility. All excess tax benefits and deficiencies on share-based payment awards are recognized as income tax expense or benefit in the Consolidated Statements of Operations. In addition, the tax effects of exercised or vested awards are treated as discrete items in the reporting period in which they occur and excess tax benefits or deficiencies are classified with other income tax cash flows as an operating activity in the Consolidated Statements of Cash Flows. We recognize forfeitures as they occur.

We have compensation arrangements Acadian LLC whereby in exchange for continued service, Acadian LLC equity is either purchased by or granted to key employees and may be repurchased either by Acadian LLC key employees or by us at a future date, subject to service requirements having been met. Awards of equity made to key employees are accounted for as cash-settled, with the fair value recognized as compensation expense over the requisite service period, with a corresponding liability carried within other compensation liabilities on the Consolidated Balance Sheets until the award is settled by us. The fair values of the liabilities are determined with the assistance of third party valuation specialists using discounted cash flow analyses which incorporate assumptions for the forecasted earnings information, growth rates, market risk adjustments, discount rates, when award holders maximize value and post-vesting restrictions. While we believe all assumptions used in determining the fair value of the liabilities are reasonable and appropriate, certain assumptions are subjective and changes in these assumptions could result in different fair value amounts.

**Taxation** 

We file tax returns directly with the U.S., U.K., state tax authorities and in other foreign jurisdictions. These tax returns represent our filing positions within each jurisdiction and settle our tax liabilities. Each jurisdiction has the right to audit those tax returns and may take different positions with respect to income and expense allocations and taxable earnings determinations. Because the determinations of our annual provisions are subject to judgments and estimates, it is possible that actual results will vary from those recognized in our Consolidated Financial Statements. As a result, it is likely that additions to, or reductions of, income tax expense will occur each year for prior reporting periods as actual tax returns and tax audits are settled.

------

Deferred tax assets, net of any associated valuation allowance, have been recognized based on management's belief that taxable income of the appropriate character, more likely than not, will be sufficient to realize the benefits of these assets over time. In the event that actual results differ from our expectations, or if our historical trends of positive operating income changes, we may be required to record a valuation allowance on some or all of these deferred tax assets, which may have a significant effect on our financial condition and results of operations. In assessing whether a valuation allowance should be established against a deferred tax asset, we consider the nature, frequency and severity of recent losses, forecasts of future profitability, the duration of statutory carryback and carry forward periods, among other factors.

We utilize a specific recognition threshold and measurement attribute for the Consolidated Financial Statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The prescribed two-step process for evaluating a tax position involves first determining whether it is more likely than not that a tax position will be sustained upon examination by the appropriate taxing authorities. If it is, the second step then requires a company to measure this tax position benefit as the largest cumulative amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Unrecognized tax benefits and related interest and penalties are adjusted periodically to reflect changing facts and circumstances.

**Recent Accounting Developments**

See discussion of Recent Accounting Developments in Note 2 of the accompanying Consolidated Financial Statements.

**Item 7A.&nbsp;&nbsp;&nbsp;&nbsp;Quantitative and Qualitative Disclosures About Market Risk**

**Market Risk**

Our exposure to market risk is directly related to our role as an asset manager. Substantially all of our investment management revenues are derived from our agreements with our clients. Under these agreements, the revenues we receive are based on the value of our assets under management or the investment performance on client accounts for which we earn performance fees. Accordingly, our revenues and net income may decline as a result of our assets under management decreasing due to depreciation of our investment portfolios. In addition, such depreciation could cause our clients to withdraw their funds in favor of investments offering higher returns or lower risk, which would cause our revenues and net income to decline further.

Our model for assessing the impact of market risk on our results uses December 31, 2025 ending AUM and management fee rates as the basis for management fee revenue calculations. With respect to performance fee revenue, we assume that relative investment performance remains the same as it was on December 31, 2025. Therefore, market-driven changes in performance fees, which are typically based on relative performance versus market indices, reflect changes in the underlying AUM used in the calculation rather than differences in relative performance as a result of a changed market environment. The impact that market changes have on performance fee eligible accounts varies due to high-water marks and other measurement hurdles which are not factored in this analysis. Changes in performance fee revenues could be significant in each period. The basis for the analysis is performance fees earned for the twelve months ended December 31, 2025.

------

Our profit sharing economic structure, described more fully in "Management's Discussion and Analysis of Financial Condition and Results of Operation—The Economics of Our Business," results in a sharing of market risk between us and our employees. Approximately 39% of our ENI cost structure is variable, representing variable compensation and Acadian LLC key employee distributions. These variable expenses generally are linked in a formulaic manner to the profitability of the business after covering operating expenses, which include base compensation and benefits, general and administrative expenses, and depreciation and amortization. In modeling the impact of market risk, we assume that these operating expenses remain unchanged, but the resulting impact on profit driven by increases or decreases in revenue will change variable compensation and Acadian LLC key employee distributions in line with their formulaic calculations. Any change in pre-tax profit is tax-affected to calculate profit after tax.

The value of our assets under management was $177.5 billion as of December 31, 2025. A 10% increase or decrease in the value of our assets under management, if proportionally distributed over all of our investment strategies, asset classes and client relationships, would cause an annualized increase or decrease in our gross management fee revenues of approximately $61 million based on our effective weighted average fee rate of approximately 34 basis points in the most recent quarter. Approximately $23 billion, or 13%, of our AUM, are in accounts subject to performance fees. Of these assets, the majority are in accounts for which performance fees are calculated based on investment return that differs from the relative benchmark returns. Assuming the market change does not impact our relative performance, a 10% increase or decrease in AUM would have a $3 million impact to our gross performance fees based on our trailing twelve-month performance fees of $31 million as of December 31, 2025. The combined impact on our management fees and performance fees would have a direct impact on our earnings and result in an annual change of approximately $25 million in our post-tax economic net income. The analysis is based on our operating model, effective cost and fee structure in the quarter ended December 31, 2025.

Equity market risk, interest rate risk, and foreign currency risk are the market risks that could have the greatest impact on our management fees, performance fees and our business profitability. Impacts on our management and performance fees can be calculated based on the percentage of AUM constituting equity investments, or foreign currency denominated investments, respectively, multiplied by the relevant weighted average management fee and performance fee attributable to that asset class.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our equity markets-based AUM includes U.S., global, non-U.S. and emerging markets equities (including small cap through large cap securities). A 10% increase or decrease in equity markets would cause our approximately $177 billion of long-only equity assets under management to increase or decrease by $18 billion, resulting in a change in annualized management fee revenue of $60 million and an annual change in post-tax economic net income of approximately $23 million, given our current cost structure, operating model, and weighted average equity fee rates of 34 basis points at the current mix of strategies as of December 31, 2025. Approximately $23 billion, or 13%, of our equity markets-based AUM are in accounts subject to performance fees. Of these assets, the majority are in accounts for which performance fees are calculated based on investment return in excess of the relative benchmark returns. Assuming the market change does not impact our relative performance, a 10% change in equity markets would have an approximate incremental $1 million impact from performance fees on our post-tax economic net income. The analysis is based on our operating model, effective cost and fee structure in the quarter ended December 31, 2025.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Foreign currency AUM includes equity assets denominated in foreign currencies. Assuming that all other factors remain constant, including client activity and asset flows and pricing, we estimate that a 10% increase or decrease in foreign exchange rates against the U.S. dollar would cause our $125 billion of foreign currency denominated AUM to increase or decrease by $13 billion, resulting in a change in annualized management fee revenue of $48 million and an annual change in post-tax economic net income of $19 million, based on effective weighted average fees earned on our foreign currency denominated AUM of 39 basis points at the mix of strategies as of December 31, 2025. Approximately $16 billion, or 13%, of our foreign currency denominated AUM are in accounts subject to performance fees. Of these assets, the majority are in accounts for which performance fees are calculated based on investment return that differs from the relative benchmark returns. Assuming the market change does not impact our relative performance, a 10% change in foreign currency exchange rates would have an approximate incremental $1 million impact from performance fees on our post-tax economic net income. The analysis is based on our operating model, effective cost and fee structure in the quarter ended December 31, 2025.

While the analysis above assumes that market changes occur in a uniform manner across the relevant portfolio, because of our declining fee rates for larger relationships and differences in our fee rates across asset classes, a change in the composition of our assets under management, in particular an increase in the proportion of our total assets under management attributable to strategies, clients or relationships with lower effective fee rates, could have a material negative impact on our overall weighted average fee rate.

As is customary in the asset management industry, clients invest in particular strategies to gain exposure to certain asset classes, which exposes their investment to the benefits and risks of such asset classes. We have not adopted a corporate-level risk management policy regarding client assets, nor have we attempted to hedge at the corporate level or within individual strategies the market risks that would affect the value of our overall assets under management and related revenues. Any reduction in the value of our assets under management would result in a reduction in our revenues.

**Interest Rate Risk**

We are exposed to interest rate risks primarily through borrowings under Acadian LLC's revolving credit facility and Delayed Draw Term Loan. Interest on borrowings under the revolving credit facility and Delayed Draw Term Loan are based upon variable interest rates. There was no balance drawn on our revolving credit facility as of December 31, 2025. We currently do not hedge against interest rate risk. As of December 31, 2025, a hypothetical 10% change in interest rates would have resulted in an immaterial change to our interest expense during the twelve months ended December 31, 2025.

**Report of Independent Registered Public Accounting Firm**

To the Stockholders and Board of Directors

Acadian Asset Management Inc.:

*Opinion on the Consolidated Financial Statements*

We have audited the accompanying consolidated balance sheets of Acadian Asset Management Inc. and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive income, changes in stockholders' equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025 based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 27, 2026 expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting.

*Basis for Opinion*

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

*Critical Audit Matter*

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

*Assessment of the fair value measurement of the cash-settled subsidiary awards liability*

As discussed in Notes 2, 11 and 18 to the consolidated financial statements, the Company has issued cash-settled equity awards to certain key employees of the subsidiary which are liability classified. The total liability

------

for these awards was $37.0 million at December 31, 2025. The liability is remeasured each reporting period to its fair value. The fair value is determined using discounted cash flow analysis which incorporate assumptions for the forecasted earnings information, growth rates, market risk adjustments, discount rates, and when award holders maximize value subject to post-vesting restrictions.

We identified the assessment of the fair value measurement of the cash-settled awards liability as a critical audit matter. Complex and subjective auditor judgment was required in evaluating the methodology and key assumptions used in determining the fair value of the liability related to the cash-settled awards. The significant assumptions that required complex and subjective auditor judgment include forecasted earnings, growth rates, market risk adjustments, discount rates, and adjustments to reflect the impact of post-vesting restrictions and when award holders will maximize value. Changes to these assumptions could have had an effect on the Company's determination of the fair value of the cash-settled awards liability.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company'sprocess to determine the fair value of the cash-settled awards liability, including controls over the significant assumptions noted above. We compared forecasted earnings and growth rates to internal financial forecasts and historical results. We also compared certain inputs used in developing the forecasted earnings and growth rates to third party data. We held discussions with finance personnel of the Company to further evaluate the forecasted earnings used in the discounted cash flow models. We evaluated adjustments to reflect the impact of post-vesting restrictions on awards by comparing the restrictions to underlying plan documents and also assess that puts occur when award holders maximize value. We involved valuation professionals with specialized skills and knowledge, who assisted in:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• evaluating whether the methodology used to calculate the fair value of the awards was appropriate

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• performing calculations of market risk adjustments using data that was independently obtained or otherwise corroborated

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• evaluating the discount rates used by the Company by comparing them against discount rates that were developed using publicly available market data

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• performing calculations of the fair value of the liability using the Company's forecasted earnings and a combination of independent assumptions and Company assumptions and comparing the result to the amount recorded by the Company.

**Report of Independent Registered Public Accounting Firm**

To the Stockholders and Board of Directors

Acadian Asset Management Inc.:

*Opinion on Internal Control Over Financial Reporting*

We have audited Acadian Asset Management Inc. and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive income, changes in stockholders' equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements), and our report dated February 27, 2026 expressed an unqualified opinion on those consolidated financial statements.

*Basis for Opinion*

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report of Management on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

*Definition and Limitations of Internal Control Over Financial Reporting*

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

**1) Organization and Description of the Business**

Acadian Asset Management Inc. ("Acadian", "AAMI" or the "Company"), is a holding company that operates a systematic investment management business through its majority owned subsidiary, Acadian Asset Management LLC ("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 the Company's 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.

Acadian LLC is organized as a limited liability company. Fees for services are largely asset-based and, as a result, revenues fluctuate based on the performance of financial markets and investors' asset flows in and out of Acadian LLC's products. The Company utilizes a profit-sharing model in structuring its compensation and ownership arrangements with Acadian LLC. Variable compensation is based on the firm's profitability. The Company and Acadian LLC key employees share in profits after variable compensation according to their respective ownership interests. The profit-sharing model results in the alignment of the Company and Acadian LLC key employee economic interests, which is critical to the Company's talent management strategy and long-term growth of the business.

Prior to 2014, the Company was a wholly-owned subsidiary of Old Mutual plc ("OM plc"), an international long-term savings, protection, and investment group, listed on the London Stock Exchange. On October 15, 2014, the Company completed the initial public offering (the "Offering") by OM plc pursuant to the Securities Act of 1933, as amended. As part of the Offering, the Company was authorized to issue up to 230 million shares of $0.001 par value per share common stock. As of December 31, 2025, Paulson & Co. Inc. ("Paulson") and related parties thereof held approximately 21.8% of the common stock of the Company.

**Notes to Consolidated Financial Statements (Continued)**

**December 31, 2025 and 2024**

**2) Basis of Presentation and Significant Accounting Policies**

The Company's significant accounting policies are as follows:

**Basis of presentation**

These Consolidated Financial Statements reflect the historical balance sheets, statements of operations, statements of comprehensive income, statements of changes in stockholders' equity and statements of cash flows of the Company. Within these Consolidated Financial Statements, Paulson and its related entities, as defined above, are considered "related parties."

The Consolidated Financial Statements are prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP"). All dollar amounts, except per-share data in the text and tables herein, are stated in millions of United States Dollars ("USD") unless otherwise indicated. Transactions between the Company and its related parties are included in the Consolidated Financial Statements.

**Revenue recognition**

&nbsp;&nbsp;&nbsp;&nbsp;***Revenue from contracts with customers***

The Company recognizes revenue in accordance with Accounting Standards Codification Topic 606 ("ASC 606"), *Revenue from Contracts with Customers*. Revenue is recognized in a manner that depicts the Company's transfer of promised services to its customers in an amount that reflects the consideration the Company expects to receive in exchange for those services net of certain rebates.

The application of ASC 606 requires an entity to identify its contract(s) with a customer, identify the performance obligations in the contract(s), determine the transaction price, allocate the transaction price to the performance obligations in the contract(s), and recognize revenue when (or as) the entity satisfies a performance obligation.

A performance obligation, the unit of account under ASC 606, is a promise in a contract to transfer a distinct good or service to a customer. The majority of the Company's contracts contain a single performance obligation, the delivery of investment management services. The promise to transfer these services is not separately identifiable from any other promises in the contracts and, therefore, not distinct. In these contracts, the Company earns a management fee for providing its services. These fees are the consideration to which the Company expects to be entitled in exchange for transferring the promised services to the customer. The Company recognizes revenue for its investment management services ratably over time on a monthly basis, because the customer simultaneously receives and consumes the benefits of the services as they are performed.

The Company's management fee revenue is calculated based upon levels of assets under management ("AUM") multiplied by a fee rate. Management fee revenue is typically calculated on a monthly or quarterly basis. In certain of the Company's contracts, the transaction price is variable, because AUM is based on an average over a specified period. In determining the transaction price, variable consideration is included only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized would not occur when the uncertainty associated with the variable consideration is resolved. The Company's variability around these fees is typically resolved by the end of each period when the actual average AUM for that contract period is calculated.

**Notes to Consolidated Financial Statements (Continued)**

**December 31, 2025 and 2024**

**2) Basis of Presentation and Significant Accounting Policies (cont.)**

Certain of the Company's contracts include performance-based fees in addition to or in lieu of management fees. Performance fees are generally assessed as a percentage of the investment performance realized on a client's account. Performance fees are recognized when they (i) become billable to customers (based on contractual terms of agreements) and (ii) are not subject to contingent repayment.

The Company is required to capitalize certain costs directly related to the acquisition of a customer or the fulfillment of a contract with a customer. The Company has noted no instances where sales-based compensation or similar costs met the definition of an incremental cost to acquire a contract with a customer. There are no instances where the Company has incurred costs to fulfill a contract with a customer, therefore no assets related to contract acquisition or fulfillment have been recognized.

For each revenue contract, the Company assesses each performance obligation and determines if it is the principal in the transaction (where the nature of its promise is to provide a specified good or service itself) or an agent in the transaction (where the nature of its promise is to arrange for a good or service to be provided by another party). In instances where a customer reimburses the Company for a cost paid on the customer's behalf, if the Company is acting as a principal, the reimbursement is recorded on a gross basis and if the Company is acting as an agent, the reimbursement is recorded on a net basis.

***&nbsp;&nbsp;&nbsp;&nbsp;Revenue from other sources***

Revenue from other sources includes interest income on cash and cash equivalents.

**Compensation arrangements**

The Company operates a short term variable compensation arrangement where generally, a percentage of Acadian LLC's annual pre-variable compensation earnings, as defined in the arrangement, is allocated to a "pool" of Acadian LLC's key employees, and subsequently distributed to individuals subject to recommendation and approval of a remuneration committee comprised of both the Company's and Acadian LLC's management. Additionally, a contractual percentage of Acadian LLC performance fee revenues and post-bonus profits are included in a deferred compensation pool. The deferred compensation pool is allocated to Acadian LLC key employees and is subject to a three-year vesting period. Variable compensation expense is accrued and recognized in the Consolidated Statements of Operations as services are provided by individual employees. Variable compensation also includes discretionary annual bonuses, which may be paid in the form of cash or awards of AAMI equity.

The Company operates a longer-term profit-interest plan whereby certain Acadian LLC key employees are granted (or have a right to purchase) awards representing a profits interest in Acadian LLC, as distinct from an equity interest due to the lack of pari passu voting rights. Under this plan, the Company may award a portion of the aforementioned variable compensation arrangement through issuance of a profits interest in Acadian LLC. The awards generally have a three-year vesting period from the grant date, and the service period begins at the commencement of the financial period to which the variable compensation relates. Under this plan, Acadian LLC key employees are eligible to share in the profits of Acadian LLC based on their respective percentage interest held.

**Acadian Asset Management Inc.**

**Notes to Consolidated Financial Statements (Continued)**

**December 31, 2025 and 2024**

**2) Basis of Presentation and Significant Accounting Policies (cont.)**

In addition, under certain circumstances, Acadian LLC key employees are eligible to receive repurchase payments upon exiting the plan based on a multiple of the last twelve months' profits of Acadian LLC, as defined in the arrangement. Profits allocated and movements in the potential repurchase value, determined based on a fixed multiple times trailing twelve-month profits, as defined, are recognized as compensation expense. Profit interests' compensation liabilities are re-measured at each reporting date at the twelve-month earnings multiple, with movements treated as compensation expense in the Company's Consolidated Statements of Operations.

**Share-based compensation plans**

The Company recognizes the cost of all share-based payments to directors, senior management, and employees, including grants of restricted stock and stock options, as compensation expense in the Consolidated Statements of Operations over the respective vesting periods.

Awards made under the Company's equity plans are accounted for as equity-settled, and the grant date fair value is recognized as compensation expense over the requisite service period, with a corresponding contribution to additional paid-in capital. Valuation of restricted stock awards ("RSAs") and restricted stock units ("RSUs") is determined based on the Company's closing share price as quoted on the New York Stock Exchange on the measurement date. For awards with a performance vesting condition, compensation expense is adjusted each period to reflect the probability of achievement of the performance condition throughout the vesting period. For market condition awards and stock options, a Monte-Carlo simulation model is used to determine the fair value. Key inputs for the model include assumed reinvestment of dividends, risk-free interest rate, expected volatility, and term. All excess tax benefits and deficiencies on share-based payment awards are recognized as income tax expense or benefit in the Consolidated Statements of Operations. In addition, the tax effects of exercised or vested awards are treated as discrete items in the reporting period in which they occur, and excess tax benefits or deficiencies are classified with other income tax cash flows as an operating activity in the Consolidated Statements of Cash Flows. The Company recognizes forfeitures as they occur.

The Company has compensation arrangements with Acadian LLC whereby in exchange for continued service, Acadian LLC equity is either purchased by or granted to Acadian LLC key employees and may be repurchased by the Company at a future date, subject to service requirements having been met. Awards of equity made to Acadian LLC key employees are accounted for as cash settled, with the fair value recognized as compensation expense over the requisite service period, with a corresponding liability carried within other compensation liabilities on the Consolidated Balance Sheets until the award is settled. The fair value of the liability is determined with the assistance of third-party valuation specialists using a discounted cash flow analysis which incorporates assumptions for the forecasted earnings information, growth rates, market risk adjustments, discount rates, when award holders maximize value and post-vesting restrictions. The liability is revalued at each reporting period, with any movements recorded within compensation expense.

**Principles of Consolidation**

The Consolidated Financial Statements include the operations of the Company, its subsidiaries, and any consolidated Funds. Intercompany balances and transactions among the Company, Acadian LLC, and consolidated Funds are eliminated in consolidation.

------

**Acadian Asset Management Inc.**

**Notes to Consolidated Financial Statements (Continued)**

**December 31, 2025 and 2024**

**2) Basis of Presentation and Significant Accounting Policies (cont.)**

The Company evaluates entities it is involved with to determine whether it has a controlling financial interest in them and is required to consolidate. Generally, majority-owned entities or otherwise controlled investments in which the Company holds a controlling financial interest as the principal shareholder, managing member, or general partner are consolidated. This assessment is performed at the time the Company becomes involved with an entity and is reassessed at each reporting date or upon the occurrence of certain events (such as contributions and redemptions, either by the Company, Acadian LLC, or third parties, or amendments to the governing documents of the Company's investees or sponsored Funds). If the Company subsequently determines that it no longer holds a controlling financial interest, the Company will deconsolidate the entity.

&nbsp;&nbsp;&nbsp;&nbsp;***Consolidation of Voting Interest Entities***

The Company has a controlling financial interest in a voting interest entity ("VOE") when it owns a majority of the voting interests through which it can exert control over significant operating, financial, and investing decisions of the entity and no noncontrolling interest holder has stated rights that would overcome the presumption of consolidation by the majority voting interest.

&nbsp;&nbsp;&nbsp;&nbsp;***Consolidation of Variable Interest Entities***

The Company has a controlling financial interest in a variable interest entity ("VIE") when it is the primary beneficiary of that entity. The primary beneficiary of a VIE is the entity that has (a) the power to direct the activities of a VIE that most significantly affect the entity's economic performance, and (b) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. An entity is considered a VIE when (i) it lacks the total equity investment at risk sufficient to enable the entity to finance its activities independently, (ii) the equity holders at risk lack the obligation to absorb losses, the right to receive residual returns, or the right to direct the activities of the entity that most significantly impact the entity's economic performance, or (iii) the entity is structured with disproportionate voting rights, and substantially all of the activities are conducted on behalf of an investor with disproportionately few voting rights.

In evaluating whether the Company is the primary beneficiary of an entity, the Company evaluates its economic interests in the entity held either directly by the Company or indirectly through related parties on a proportional basis. Management fees earned from VIEs are not generally considered variable interests if they are deemed to be at market and commensurate with service. If no single party satisfies the primary beneficiary criteria, but the Company and its related parties satisfy the criteria on a combined basis, then the primary beneficiary is the entity out of the related party group that is most closely associated to the VIE. Assessing whether an entity is a VIE involves judgment and analysis. Factors considered in this assessment include the entity's legal organization, the entity's capital structure and equity ownership and any related party or de-facto agent implications of the Company's involvement with the entity.

In the normal course of business, Acadian LLC sponsors and manages certain investment vehicles (the "Funds"). The Funds are generally considered VIEs. In most cases, the Company, through Acadian LLC, has the power to direct the activities of the Funds that most significantly affect the Funds' economic performance. For certain Funds, the Company provides seed capital to establish the Fund. For seeded Funds, the Company assesses whether or not it is the primary beneficiary of the Fund and is therefore required to consolidate the Fund.

**Acadian Asset Management Inc.**

**Notes to Consolidated Financial Statements (Continued)**

**December 31, 2025 and 2024**

**2) Basis of Presentation and Significant Accounting Policies (cont.)**

The consolidation analysis can generally be performed qualitatively, however, if it is not readily apparent that the Company is not the primary beneficiary, a quantitative analysis may also be performed. The Company generally is not the primary beneficiary of Fund VIEs created to manage assets for clients unless the Company's ownership interest in the fund, including interests of related parties on a proportional basis, is significant. VIEs are subject to specific disclosure requirements. See Note 5 for additional disclosures pertaining to the Company's involvement with VIEs.

**Investments and Investment Transactions**

***&nbsp;&nbsp;&nbsp;&nbsp;Valuation of investments held at fair value***

Valuation of Fund investments is evaluated pursuant to the fair value methodology discussed below. Other investments are categorized as trading and recorded at estimated fair value. Realized and unrealized gains and losses arising from changes in fair value of investments are reported within net consolidated funds' investment gains and losses in the Consolidated Statements of Operations. See Note 4 for a summary of the inputs utilized to determine the fair value of other investments held at fair value.

***&nbsp;&nbsp;&nbsp;&nbsp;Security transactions***

The Company generally records securities transactions on a trade-date basis. Realized gains and losses on securities transactions are generally determined on the average-cost method (net of foreign capital gain taxes) and for certain transactions determined based on the specific identification method.

***&nbsp;&nbsp;&nbsp;&nbsp;Income and expense recognition***

The Company records interest income on an accrual basis and includes amortization of premiums and accretion of discounts. Dividend income is recorded on the ex-dividend date, net of applicable withholding taxes. Expenses are recorded on an accrual basis.

***Short sales***

Certain Funds may sell a security they do not own in anticipation of a decline in the fair value of that security. When a Fund sells a security short, it must borrow the security sold short and deliver it to the broker-dealer through which it made the short sale. The short sales are secured by the long portfolio and available cash. The dollar value of which is at least equal to the market value of the security at the time of the short sale. The Fund records a gain, limited to the price at which the Fund sold the security short, or a loss, unlimited in size, upon the termination of a short sale. The amount of the gain or loss will be equal to the proceeds received in entering into the short sale less the cost of buying back the short security to close the short position. While the transaction is open, the Fund will incur an expense for any accrued dividends or interest which is paid to the lender of the securities. These short sales may involve a level of risk in excess of the liability recognized in the accompanying Consolidated Balance Sheets. The extent of such risk cannot be quantified.

**December 31, 2025 and 2024**

**2) Basis of Presentation and Significant Accounting Policies (cont.)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***Funds' Derivatives***

Certain Funds may use derivative instruments. The Funds' derivative instruments may include (but are not limited to) foreign currency exchange contracts, credit default swaps, equity swaps, interest rate swaps, financial futures contracts, and warrants. The fair values of derivative instruments are recorded as other assets of consolidated Funds or other liabilities of consolidated Funds on the Company's Consolidated Balance Sheets. Certain of the Funds have historically used foreign exchange forwards to hedge the risk of movement in exchange rates on financial assets on a limited basis.

The Company's Funds have not designated any financial instruments for hedge accounting, as defined in the accounting literature, during the periods presented. The gains or losses on a Fund's derivative instruments not designated for hedge accounting are included as net consolidated Funds gains or losses in the Company's Consolidated Statements of Operations.

**Foreign currency translation and transactions**

Assets and liabilities of non-U.S. consolidated entities for which the local currency is the functional currency are translated at current exchange rates as of the end of the accounting period. The related revenues and expenses are translated at average exchange rates in effect during the period. Net exchange gains and losses resulting from translation are excluded from income and are recorded as part of accumulated other comprehensive income (loss). Transactions denominated in a foreign currency are remeasured at the current exchange rate at the transaction date and any related gains and losses are recognized in earnings.

**Fair value measurements**

Fair value is defined as the price that the Company expects to be paid upon the sale of an asset or expects to pay upon the transfer of a liability in an orderly transaction between market participants. There is a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability. Inputs may be observable or unobservable and refer broadly to the assumptions that market participants would use in pricing the asset or liability. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from independent sources. Unobservable inputs reflect the Company's own conclusions about the assumptions that market participants would use in pricing the asset or liability based on the best information available in the circumstances. Each investment is assigned a level based upon the observability of the inputs which are significant to the overall valuation. Assets and liabilities measured and reported at fair value are classified and disclosed in one of the following categories:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level I—Quoted prices are available in active markets for identical investments as of the reporting date. The type of investments included in Level I include listed equities and listed derivatives. As required by U.S. GAAP, the Company does not adjust the quoted price for these investments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level II—Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reporting date, and fair value is determined through the use of models or other valuation methodologies utilizing observable market inputs other than quoted prices. Investments which are generally included in this category include corporate bonds, less liquid and restricted equity securities, and certain over-the-counter derivatives.

**December 31, 2025 and 2024**

**2) Basis of Presentation and Significant Accounting Policies (cont.)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level III—Pricing inputs are unobservable for the asset or liability and include assets and liabilities where there is little, if any, market activity for the investment. The inputs into the determination of fair value require significant management judgment or estimation.

In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the investment. In cases in which the fair value of an investment is established using the net asset value (or its equivalent) as a practical expedient, the investment is not categorized within the fair value hierarchy.

**Use of estimates**

The preparation of these Consolidated Financial Statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the period. Assumptions used in management's estimates are based on historical experience and other factors, and these assumptions require management to exercise judgment in the process of applying the Company's accounting policies. Factors that may impact management's estimates include expectations related to future events that management considers reasonable under the facts and circumstances. Actual results could differ from such estimates, and the differences may be material to the Consolidated Financial Statements.

**Operating segment**

The Company currently operates one reportable segment, Quant & Solutions, related to investment management services and products primarily to institutional clients. The Quant & Solutions segment consists of our ownership interest in Acadian LLC. See Note 21 for further information regarding the Company's segment.

**Derivatives and Hedging**

The Company may utilize derivative financial instruments to hedge the risk of movement of interest rates and foreign currency on financial assets and liabilities. These derivative financial instruments may or may not qualify as hedges for accounting purposes. The Company records all derivative financial instruments as either assets or liabilities on its Consolidated Balance Sheets and measures these instruments at fair value. For a derivative financial instrument that qualifies as a hedge for accounting purposes and is designated as a hedging instrument, the effective portion of the derivative's gain or loss is initially reported as a component of other comprehensive income (loss) and subsequently reclassified into earnings over the life of the hedge. The ineffective portion of the gain or loss is recognized in earnings immediately.

**Cash and cash equivalents**

The Company considers all highly liquid investments, including money market mutual funds with original maturities of three months or less, to be cash equivalents. Cash equivalents are stated at cost, which approximates market value due to the short-term maturity of these investments.

**December 31, 2025 and 2024**

**2) Basis of Presentation and Significant Accounting Policies (cont.)**

Cash held by consolidated Funds is not available to fund general liquidity needs of the Company and is therefore classified as restricted cash.

**Investment advisory fees receivable**

The Company earns management and performance fees which are billed monthly, quarterly, or annually, according to the terms of the relevant investment management agreement. Management and performance fees that have been earned but have not yet been collected are presented as investment advisory fees receivable on the Consolidated Balance Sheets. Due to the short-term nature and liquidity of these receivables, the carrying amounts approximate their fair values. The Company typically does not record an allowance for doubtful accounts or bad debt expense, or any amounts recorded have been immaterial.

**Fixed assets** 

Fixed assets are recorded at historical cost and depreciated using the straight-line method over their estimated useful lives. The estimated useful lives of office equipment and furniture and fixtures range from three to ten years. Leasehold improvements are amortized over the shorter of their estimated useful lives or the remaining term of the lease. Computer software developed or obtained for internal use capitalized during the application development stage is amortized using the straight-line method over the estimated useful life of the software, which is generally five years or less. The costs of improvements that extend the life of a fixed asset are capitalized, while the costs of repairs and maintenance are expensed as incurred.

**Goodwill**

The Company records goodwill when the consideration transferred in a business combination exceeds the fair value of the identifiable net assets obtained. Goodwill is not amortized but rather is assessed for impairment at least annually using a qualitative and, if necessary, a quantitative approach.

The Company performs its assessment for impairment of goodwill annually as of the first business day of the fourth quarter, or more frequently if then current facts and circumstances indicate an impairment may exist. Factors that could indicate an impairment include significant underperformance relative to historical or projected future operating results, significant changes in the Company's use of the acquired assets in a business combination or the strategy for the Company's overall business, and significant negative industry or economic trends.

**Notes to Consolidated Financial Statements (Continued)**

**December 31, 2025 and 2024**

**2) Basis of Presentation and Significant Accounting Policies (cont.)**

Goodwill is tested for impairment at the reporting unit level. The Company has one reporting unit, consisting of Acadian LLC, as of the annual goodwill impairment test date. The Company first considers various qualitative factors to determine if it is more likely than not that the fair value of the reporting unit is greater than its respective carrying amount, including goodwill. If, based on the qualitative assessment, it is determined that it is more likely than not that the fair value of the reporting unit is less than its respective carrying amount, therefore indicating that impairment may exist, the impact would be determined at that point through a quantitative assessment. For purposes of assessing potential impairment, the fair value of the reporting unit is estimated and compared to the carrying value of the reporting unit. The fair value of a reporting unit is based on discounted estimated future cash flows. The assumptions used to estimate fair value include management's estimates of future growth rates, operating cash flows, discount rates, and terminal value. These assumptions and estimates can change in future periods based on market movement and factors impacting the expected business performance. Changes in assumptions or estimates could materially affect the determination of the fair value of the reporting unit. If it is determined that the carrying value of the reporting unit exceeds its fair value, the Company will recognize an impairment charge for the excess; not to exceed the total amount of goodwill allocated to that reporting unit.

Based on the Company's most recent annual goodwill impairment test, the Company concluded that the fair value of its reporting unit was more likely than not in excess of their carrying value. At the close of each year, management assessed whether there were any conditions present during the fourth quarter that would indicate impairment subsequent to the initial assessment date and concluded that no such conditions were present.

**Leases**

Contracts are evaluated at inception to determine whether such contract is or contains a lease. A lease is a contract that provides the right to control an identified asset for a period of time in exchange for consideration. For identified leases, the Company determines the classification as either an operating or finance lease. The Company currently leases certain office space and equipment which are classified as operating leases. Certain leases include lease and non-lease components, which the Company generally accounts for as a single component for all classes of assets.

The Company's lease agreements may contain renewal options and early termination clauses exercisable by the Company, rent escalation clauses, and/or other incentives provided by the landlord. Renewal options and early termination clauses that have been determined to be reasonably certain to be exercised are factored into the lease term. Rights and obligations attributable to identified leases with a term in excess of twelve months are recognized on the Company's Consolidated Balance Sheets in the form of right-of-use (ROU) assets and operating lease liabilities. These balances are recognized when the underlying assets are made available for use by the lessor, which may be the date the Company gains access to begin leasehold improvements. Lease payments related to short-term leases with a term of twelve months or less are not capitalized and rather are recognized as short-term lease expense.

Operating lease liabilities are initially and subsequently measured at the present value of future unpaid lease payments over the remaining lease term. For the purposes of this calculation, lease payments generally consist of fixed monthly lease payments related to use of the underlying assets. The Company uses its incremental borrowing rate to determine the present value of future unpaid lease payments based on information available at the lease commencement date.

**Notes to Consolidated Financial Statements (Continued)**

**December 31, 2025 and 2024**

**2) Basis of Presentation and Significant Accounting Policies (cont.)**

ROU assets are initially valued equal to the corresponding lease liabilities, adjusted for any lease incentives payable to the Company. Subsequently, the amortization of ROU assets is recognized as a component of operating lease expense.

The total cost of operating leases is recognized on a straight-line basis over the lease term and is composed of imputed interest on lease liabilities measured using the effective interest method and amortization of the ROU asset. Variable lease payments are primarily related to services such as common-area maintenance, utilities, property taxes, and insurance, and are recognized as variable lease expense when incurred.

ROU assets are tested for impairment whenever changes in facts or circumstances indicate that the carrying amount of an asset may not be recoverable. When the terms of a lease agreement are changed, management assesses the contract for a lease modification. Modifications of a lease generally result in remeasurement of the lease liability and the ROU asset.

**Earnings per share**

The Company calculates basic and diluted earnings per share ("EPS") by dividing net income by its shares outstanding as outlined below. Basic EPS attributable to the Company's stockholders is calculated by dividing "Net income attributable to controlling interests" by the weighted-average number of shares outstanding. Diluted EPS is similar to basic EPS, but adjusts for the effect of potential shares of common stock unless they are antidilutive. For periods with a net loss, potential shares of common stock are considered antidilutive.

The Company considers two ways to measure dilution to earnings per share: (a) calculate the net number of shares that would be issued assuming any related proceeds are used to buy back outstanding shares (the treasury stock method), or (b) assume the gross number of shares are issued and calculate any related effects on net income available for stockholders (the if-converted or two-class method). As appropriate, the Company's policy is to apply the more dilutive methodology upon issuance of such instruments.

**Deferred financing costs**

The Company records debt issuance costs of term loans as a direct deduction from the carrying amount of the associated debt liability. The Company records debt issuance costs of line-of-credit and revolving-debt arrangements as an asset and subsequently amortizes the deferred costs ratably over the term of the arrangements.

**Income taxes**

Deferred income taxes are recognized for the effects of temporary differences between the tax basis of an asset or liability and its reported amount in the Consolidated Financial Statements. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

**Acadian Asset Management Inc.**

**Notes to Consolidated Financial Statements (Continued)**

**December 31, 2025 and 2024**

**2) Basis of Presentation and Significant Accounting Policies (cont.)**

Deferred income tax assets are subject to a valuation allowance if, in management's opinion, it is not more-likely-than-not that these benefits will be realized. In evaluating the Company's ability to recover its deferred tax assets, the Company considers all available positive and negative evidence including its past operating results, the existence of cumulative earnings or losses in the most recent years and its forecast of future taxable income. In estimating future taxable income, the Company develops assumptions including the amount of future pre-tax operating income and the reversal of temporary differences. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates the Company is using to manage the underlying businesses.

The Company's accounting policy is to treat the global intangible low-taxed income taxes as period costs in the accounting and tax periods in which they are incurred.

A tax benefit should only be recognized if it is more-likely-than-not that the position will be sustained based on its technical merits. The Company recognizes the financial statement benefit of a tax position only after considering the probability that a tax authority would uphold the position in an examination. For tax positions meeting a "more-likely-than-not" threshold, the amount recognized in the financial statements is the largest cumulative amount of benefit greater than 50% likely of being sustained. The more-likely-than-not threshold must continue to be met in each reporting period to support continued recognition of the benefit. Unrecognized tax benefits and related interest and penalties are adjusted periodically to reflect changing facts and circumstances. The Company's accounting policy is to classify interest and related charges as a component of income tax expense.

**Non-controlling interests**

For certain entities that are consolidated, but not 100% owned, the Company reports non-controlling interests as equity on its Consolidated Balance Sheets. The Company's consolidated net income on the Consolidated Statements of Operations includes the income (loss) attributable to non-controlling interest holders of Funds. Ownership interests held by Acadian LLC key employees are categorized as liabilities on the Consolidated Balance Sheets and are revalued each reporting date, with movements treated as compensation expense in the Consolidated Statements of Operations.

Non-controlling interests in consolidated Funds on the Consolidated Balance Sheets include undistributed income owned by the investors in the respective Funds. The Company's consolidated net income on the Consolidated Statements of Operations includes the income (loss) attributable to non-controlling interest holders of these consolidated entities.

**Redeemable non-controlling interests**

The Company includes redeemable non-controlling interests related to certain consolidated Funds as temporary equity on the Consolidated Balance Sheets. Non-controlling interests in certain consolidated Funds are subject to monthly or quarterly redemption by the investors. When redeemable amounts become legally payable to investors, they are classified as a liability and included in total liabilities of consolidated Funds on the Consolidated Balance Sheets.

**Other comprehensive income (loss)**

Other comprehensive income (loss) is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances, excluding those resulting from investments by and distributions to owners. For the Company's purposes, comprehensive income (loss) represents net income (loss), as presented in the accompanying Consolidated Statements of Operations, adjusted for foreign currency translation adjustments, net of tax and adjustments to the valuation and amortization of certain derivative securities, net of tax.

**Recently adopted accounting standards**

In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. This amendment requires annual and interim disclosures of significant segment expenses that are regularly provided to the chief operating decision maker by reportable segment and clarifies that single reportable segment entities are required to apply all existing segment disclosures in the guidance. This amendment is effective for annual periods beginning after December 15, 2023, and for interim periods beginning after December 15, 2024. The Company adopted the updated guidance for the annual reporting period beginning January 1, 2024, which did not result in a material impact to our Consolidated Financial Statements. Refer to Note 21 for related disclosures about our reportable operating segment.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures, which requires public entities, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. This amendment is effective for annual periods beginning after December 15, 2024. The Company adopted the updated guidance for the annual reporting period beginning January 1, 2025, which did not result in a material impact to our Consolidated Financial Statements and related disclosures.

In March 2024, the FASB issued ASU 2024-01, Compensation - Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards. This standard provides clarity regarding whether profits interest and similar awards are within the scope of Topic 718 of the Accounting Standards Codification. This amendment is effective for annual periods beginning after December 15, 2024, and interim periods within those annual periods. Early adoption is permitted. The Company adopted the updated guidance for the annual reporting period beginning January 1, 2025, which did not result in a material impact to our Consolidated Financial Statements and related disclosures.

**New accounting standards not yet adopted** 

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-4): Disaggregation of Income Statement Expenses, which requires disclosures of additional information and disaggregation of certain expenses included in the income statement. This amendment is for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. The Company is evaluating the impact that the adoption will have on the Consolidated Financial Statements and have not yet determined the transition approach.

In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which clarifies and modernizes the accounting for internal-use software costs. This amendment is for annual periods beginning after December 15, 2027, and interim periods within those annual periods. The Company is evaluating the impact that the adoption will have on the Consolidated Financial Statements.

In November 2025, the FASB issued ASU 2025-09, Derivatives and Hedging (Topic 815): Hedge Accounting Improvements to the Accounting for derivatives and hedging, which aims to more closely align hedge accounting with the economics of an entity's risk management activities. This amendment is for annual periods beginning after December 15, 2026, and interim periods within those annual periods. The Company does not expect the additional disclosure requirements under ASU 2025-09 to have a material impact on the Consolidated Financial statements.

The Company has considered all other newly issued accounting guidance that is applicable to the Company's operations and the preparation of the Consolidated Financial Statements, including those that have not yet been adopted. The Company does not believe that any such guidance has or will have a material effect on its Consolidated Financial Statements and related disclosures.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)Assets and liabilities measured at fair value are comprised of financial investments managed by Acadian LLC.

Equity securities and derivatives which are traded on a national securities exchange are stated at the last reported sales price on the day of valuation. To the extent these securities are actively traded and valuation adjustments are not applied, they are classified as Level I. The securities that trade in markets that are not considered to be active but are valued based on quoted market prices, dealer quotations or alternative pricing sources supported by observable inputs obtained by the Company from independent pricing services are classified as Level II.

The Company obtains prices from independent pricing services that may utilize broker quotes, but generally the independent pricing services will use various other pricing techniques which take into account appropriate factors such as yield, quality, coupon rate, maturity, type of issue, trading characteristics and other data. The Company has not made adjustments to the prices provided. Assets of consolidated Funds also include investments in Corporate bonds.

**December 31, 2025 and 2024**

**4) Fair Value Measurements (cont.)**

If the pricing services are only able to (a) obtain a single broker quote or (b) utilize a pricing model with unobservable inputs, such securities are classified as Level III. If the pricing services are unable to provide prices, the Company attempts to obtain one or more broker quotes directly from a dealer or values such securities at the last bid price obtained. In either case, such securities are classified as Level III. The Company performs due diligence procedures over third party pricing vendors to understand their methodology and controls to support their use in the valuation process to ensure compliance with required accounting disclosures.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)Investments related to long-term incentive compensation plans of $37.9 million and $48.5 million at December 31, 2025 and December 31, 2024, respectively, were investments in publicly registered daily redeemable funds (some managed by Acadian LLC), which the Company has classified as trading securities and valued using the published price as of the measurement dates. Accordingly, the Company has classified these investments as Level I.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)The uncategorized amounts of $13.3 million and $19.4 million at December 31, 2025 and December 31, 2024, respectively, relate to investments in unconsolidated Funds which consist primarily of investments in Funds and are valued using NAV which the Company relies on to determine their fair value as a practical expedient and has therefore not classified these investments in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to amounts presented in the Consolidated Balance Sheets. These unconsolidated Funds consist primarily of real estate investment Funds and other investment vehicles. The NAVs that have been provided by investees have been derived from the fair values of the underlying investments as of the measurement dates. Other investment vehicles are not subject to redemption restrictions.

The real estate investment Funds of $3.1 million and $2.9 million at December 31, 2025 and December 31, 2024, respectively, were subject to longer than monthly or quarterly redemption restrictions, and due to their nature, distributions are received only as cash flows are generated from underlying assets over the life of the Funds. The range of time over which the underlying assets are expected to be liquidated by the investees is approximately one year from December 31, 2025. The valuation process for the underlying real estate investments held by the real estate investment Funds begins with each property or loan being valued by the investment teams. The valuations are then reviewed and approved by the valuation committee, which consists of senior members of the portfolio management, finance, and research teams. For certain properties and loans, the valuation process may also include a valuation by independent appraisers. In connection with this process, changes in fair value measurements from period to period are evaluated for reasonableness, considering items such as market rents, capitalization and discount rates, and general economic and market conditions.

There were no significant transfers of financial assets or liabilities between Levels II or III during the year ended December 31, 2025.

The carrying amount of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities equal or approximate fair value based on the short-term nature of these instruments.

**5) Variable Interest Entities**

The Company, through Acadian LLC, sponsors the formation of various entities considered to be VIEs. These VIEs are primarily Funds managed by Acadian LLC and other partnership interests typically owned entirely by third-party investors. Certain Funds may be capitalized with seed capital investments from the Company and may be owned partially by Acadian LLC key employees and/or individuals that have ownership interests in Acadian LLC.

The Company's determination of whether it is the primary beneficiary of a Fund that is a VIE is based in part on an assessment of whether or not the Company and its related parties have the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. The Company, through Acadian LLC in its capacity as the investment advisor to the Funds, generally has power over the Funds and therefore the Company may be required to consolidate a Fund that is a VIE if it has potentially significant economics. Typically, the Fund's investors are entitled to substantially all of the economics of these VIEs with the exception of management fees and performance fees, if any, earned by the Company or any investment the Company has made into the Funds. The Company generally is not the primary beneficiary of Fund VIEs created to manage assets for clients unless the Company's ownership interest, including interests of related parties, is substantial.

When the Company's ownership interest in a Fund, including interests of related parties, is significant, the Company generally consolidates the VIE. If the Company subsequently determines that it no longer controls the managed funds in which it has invested, or no longer has an obligation to absorb losses or rights to receive benefits, the Company will deconsolidate the Fund.

The following table presents the assets and liabilities of Funds that are VIEs consolidated by the Company (in millions):

---

|:---|:---|:---|
| | **2025** | **2024** |
| **Assets** |  |  |
| Cash and cash equivalents | $23.2 | $3.7 |

**5) Variable Interest Entities (cont.)**

"Investments" consist of investments in equity securities, corporate bonds, and derivative securities. To the extent the Company also has consolidated Funds that are not VIEs, the assets and liabilities of those Funds are not included in the table above.

The assets of consolidated VIEs presented in the table above belong to the investors in those Funds, are available for use only by the Fund to which they belong, and are not available for use by the Company to the extent they are held by non-controlling interests. Any debt or liabilities held by consolidated Funds have no recourse to the Company's general credit.

The Company's involvement with Funds that are VIEs but that are not consolidated by the Company is generally limited to that of an investment manager and its investment in the unconsolidated VIE, if any.

(1)Fair value approximates carrying value because the credit facility and the delayed draw term loan have variable interest rates based on selected short term market rates.

(2)On October 28, 2025, Acadian LLC's $140 million revolving credit facility (the "Prior LLC Credit Agreement") was terminated and replaced with a new $175 million revolving credit facility. The weighted average interest rate for the Prior LLC Credit Agreement was 5.93%, 6.93% and 6.19% in 2025, 2024 and 2023, respectively.

(3)The difference between the principal amounts and the carrying values of the senior notes in the table above reflects the unamortized debt issuance costs and discounts.

(4)On December 1, 2025, the Company completed the full redemption of the $275 million aggregate principal amount outstanding of its 4.80% Senior Notes due July 27, 2026. As a result of this transaction, the Company recorded a $1.4 million loss on extinguishment of debt within the Consolidated Statement of Operations for the year ended December 31, 2025.

**The Delayed Draw Term Loan Credit Agreement and Revolving Credit Agreement**

On October 28, 2025 (the "Closing Date), Acadian LLC entered into a Delayed Draw Term Loan Credit Agreement among Acadian LLC, the Lenders from time to time party thereto, and Bank of America, N.A. ("Bank of America"), as the Administrative Agent (the "DDTL Credit Agreement") and a Revolving Credit Agreement among Acadian LLC, the Lenders from time to time party thereto, Bank of America, as the Administrative Agent and a L/C Issuer and the other L/C Issuers from time to time party thereto (the "Revolving Credit Agreement").

The DDTL Credit Agreement provides for a delayed draw term loan facility in an aggregate principal amount, as of the Closing Date, of up to $200 million (the "Term Facility"). The term loans mature on October 28, 2028. Subject to certain conditions, Acadian LLC may increase the size of the Term Facility to an aggregate maximum principal amount of $275 million. None of the lenders under the Term Facility are obligated to provide such additional commitments to Acadian LLC.

Loans under the DDTL Credit Agreement bear interest, at Acadian LLC's option, at a rate per annum equal to (i) Term SOFR for the applicable interest period plus an applicable margin equal to a range of 1.5% to 2.0% depending on Acadian LLC's consolidated leverage ratio or (ii) an alternate base rate (defined as a rate equal to the highest of (i) the Federal Funds Rate plus 0.5%, (ii) Bank of America's published "prime rate" and (iii) Term SOFR plus 1.0%) plus an applicable margin equal to a range of 0.5% to 1.0% depending on Acadian LLC's consolidated leverage ratio.

The weighted average interest rate for the Term Facility was 5.65% in 2025.

Financial covenants under the Term Facility include the quarterly maintenance by the Acadian LLC of (i) a maximum Consolidated Net Leverage Ratio (as defined in the DDTL Credit Agreement) of not greater than 2.5x and (ii) a minimum Consolidated Interest Coverage Ratio (calculated as the ratio of Acadian LLC Consolidated EBITDA (as defined in the DDTL Credit Agreement), divided by Acadian LLC interest expense for the four consecutive fiscal quarters ended on or immediately prior to the date of determination) of not less than 4.0x. For purposes of

**12) Borrowings and Debt (cont.)**

calculating the Consolidated Net Leverage Ratio, the DDTL Credit Agreement refers to Consolidated Funded Indebtedness (as defined in the DDTL Credit Agreement) minus unrestricted cash at Acadian LLC.

The Revolving Credit Agreement provides for senior unsecured revolving credit commitments as of the Closing Date in an aggregate principal amount, as of the Closing Date, of up to $175 million (the "Revolving Facility"). The revolving commitments mature on October 28, 2028. Subject to certain conditions, Acadian LLC may increase the size of the Revolving Facility to an aggregate maximum principal amount of $275 million, which may be established in the form of revolving commitments or term loan commitments. None of the lenders under the Revolving Facility are obligated to provide such additional commitments to Acadian LLC.

Borrowings under the Revolving Credit Agreement bear interest, at Acadian LLC's option, at a rate per annum equal to (i) Term SOFR (as defined in the Revolving Credit Agreement) for the applicable interest period plus an applicable margin equal to a range of 1.5% to 2.0% depending on Acadian LLC's Consolidated Leverage Ratio (as defined in the Revolving Credit Agreement) or (ii) an alternate base rate (defined as a rate equal to the highest of (i) the Federal Funds Rate plus 0.5%, (ii) Bank of America's published "prime rate" and (iii) Term SOFR plus 1.0%) plus an applicable margin equal to a range of 0.5% to 1.0% depending on Acadian LLC's Consolidated Leverage Ratio. The Company is required to pay a commitment fee at a per annum rate ranging from 0.25% to 0.375%, with such amount based on Acadian LLC's Consolidated Leverage Ratio on the daily undrawn amount of the revolving commitments, and customary letter of credit participation and fronting fees.

As of December 31, 2025, Acadian LLC had unused lines of credit of $172.5 million comprised of undrawn commitments on the Revolving Credit Facility of $175 million less a $2.5 million letter of credit with Bank of America related to one of the Acadian LLC's current office spaces.

**13) Income Taxes (cont.)**

During the year ended December 31, 2023, Massachusetts enacted a change in the state's apportionment formula for corporations effective for tax years beginning on or after January 1, 2025. The Company measures its deferred tax assets and liabilities at the enacted rates for the period in which these items are expected to reverse. As a result, in the year ended December 31, 2023, the Company recorded the discrete tax impact due to the effect of the change in tax law on the measurement of its deferred tax assets.

As of December 31, 2025, the Company maintains the assertion that the foreign unremitted earnings of multiple foreign subsidiaries are not permanently reinvested. The amount of deferred tax recorded during the period was not material. For foreign subsidiaries whose investments are permanent in duration, income and foreign withholding taxes have not been provided on the unremitted earnings of those subsidiaries. This amount may become taxable upon repatriation from the subsidiary or a sale or liquidation of the subsidiary. The amount of such unremitted earnings and the amount of any unrecognized deferred income tax liability on these unremitted earnings is immaterial at December 31, 2025.

The significant components of deferred tax assets and deferred tax liabilities for the years ended December 31 are as follows (in millions):

| **Net deferred tax assets** | $**77.5** | $**78.3** |

At December 31, 2025 and 2024, the Company's net deferred tax asset primarily relates to its outside basis difference in its investment in Acadian LLC, which is treated as a partnership for federal income tax purposes.

**13) Income Taxes (cont.)**

The Company assesses whether a valuation allowance should be established against its deferred income tax assets based on consideration of all available evidence, both positive and negative, using a more likely than not standard. In evaluating the Company's ability to recover its deferred tax assets, the Company considers all available positive and negative evidence including the existence of cumulative income in the most recent fiscal years, changes in the business in which the Company operates, and the Company's ability to forecast future taxable income. The weight given to the evidence is commensurate with the extent to which it can be objectively verified. The more negative evidence that exists, the more positive evidence that is necessary and the more difficult it is to support a conclusion that a valuation allowance is not needed. The Company has three years of cumulative earnings as of December 31, 2025 and 2024. As of December 31, 2025, management believes it is more likely than not that the balance of the deferred tax assets will be realized, as such, no valuation allowance is required based on forecasted taxable income.

A reconciliation of the change in gross unrecognized tax benefits for the years ended December 31 is as follows (in millions):

| Reductions related to lapses of statutes of limitations | (0.6) | (0.1) | (0.5) |
| **Balance as of December 31** | $**1.1** | $**1.3** | $**1.1** |

---

The Company's liability for uncertain tax positions includes unrecognized benefits of $0.9 million and $1.0 million at December 31, 2025 and 2024, respectively, that if recognized would affect the effective tax rate on income.

The Company recognized $0.0 million, $0.1 million, and $0.1 million in interest and penalties in its income tax provision for the years ended December 31, 2025, 2024 and 2023, respectively. The Company's liability for uncertain tax positions at December 31, 2025 and 2024 includes accrued interest and penalties of $0.2 million and $0.2 million, respectively.

The Company and its subsidiaries file tax returns in the U.S., U.K., state, local, and other foreign jurisdictions. As of December 31, 2025, the Company is generally no longer subject to income tax examinations by U.S. federal, state, local, or foreign tax authorities for calendar years prior to 2021.

The Company is periodically under examination by various taxing authorities. Examinations are inherently uncertain, may result in payment of additional taxes or the recognition of tax benefits and may be in process for extended periods of time. At December 31, 2025 the Company is subject to examination in two jurisdictions.

On July 4, 2025, H.R.1, commonly referred to as the One Big Beautiful Bill Act (the "OBBBA"), was enacted in the U.S., which includes a broad range of tax reform provisions, including extending and modifying certain key Tax Cuts and Jobs Act provisions (both domestic and international). The legislation has multiple effective dates, with certain provisions effective in 2025 and others to be implemented through 2027. The OBBBA did not have a material impact to the income tax expense during the period ended December 31, 2025.

**Operational commitments**

A number of our subsidiaries operate under regulatory authorities that require that they maintain minimum financial or capital requirements. Management is not aware of any violations of such financial requirements occurring during the periods presented.

**Guaranty**

The Company entered into a guaranty for an office space security deposit on behalf of Acadian LLC in the amount of $2.5 million in January 2020. This represents the maximum potential amount of future (undiscounted) payments that the Company could be required to make under the guaranty in the event of default by the guaranteed parties. This guaranty expires in 2033. There are no liabilities recorded on the Consolidated Balance Sheets as of December 31, 2025 and 2024, related to this guaranty.

**Litigation**

The Company is subject to claims, legal proceedings, and other contingencies in the ordinary course of its business activities. Each of these matters is subject to various uncertainties, and it is possible that some of these matters may be resolved in a manner unfavorable to the Company. The Company establishes accruals for matters for which the outcome is probable and can be reasonably estimated. As of December 31, 2025 and 2024, there were no material accruals for claims and the Company does not believe any outstanding matters will have a material adverse effect on the Company.

**Indemnifications**

In the normal course of business, the Company may enter into contracts that contain a variety of representations and warranties and which provide general indemnifications. The Company's maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Company that have not yet occurred.

**Foreign tax contingency**

The Company has clients in non-U.S. jurisdictions which require entities that are conducting certain business activities in such jurisdictions to collect and remit tax assessed on certain fees paid for goods and services provided. The Company does not believe this requirement is applicable based on its limited business activities in these jurisdictions. However, given the fact that uncertainty exists around the requirement, the Company has chosen to evaluate its potential exposure related to non-collection and remittance of these taxes. At December 31, 2025 and 2024, management of the Company has estimated the potential maximum exposure and concluded that it is not material. No accrual for the potential exposure has been recorded as the probability of incurring any potential liability relating to this exposure is not probable at December 31, 2025 and 2024.

**15) Earnings Per Share**

Basic earnings per share is calculated by dividing net income attributable to controlling interests by the weighted-average number of shares of common stock outstanding. Diluted earnings per share is similar to basic earnings per share, but is adjusted for the effect of potentially issuable common stock, except when inclusion is anti-dilutive.

The calculation of basic and diluted earnings per share of common stock for the years ended December 31, 2025, 2024 and 2023 is as follows (dollars in millions, except per share data):

**16) Revenue**

**Management fees**

The Company's management fees are a function of the fee rates charged to clients, which are typically expressed in basis points, and the levels of the Company's assets under management. The most significant driver of increases or decreases in this average fee rate is changes in the mix of the Company's assets under management caused by net inflows or outflows in certain asset classes or disproportionate market movements.

**Performance fees**

The Company's products subject to performance fees earn these fees upon exceeding high-water mark performance thresholds or outperforming a hurdle rate. Performance fees are recorded in revenues when the contractual performance criteria have been met and when it is probable that a significant reversal of revenue recognized will not occur in future reporting periods.&nbsp;&nbsp;&nbsp;&nbsp;

**17) Employee Benefits**

The Company has various defined contribution plans covering substantially all of its full-time employees. In addition to pre-tax contributions made by employees, the Company also makes contributions to the qualified plans annually.

The Company also has non-qualified defined contribution plans covering certain senior employees. The Company has established a Deferred Compensation Plan under which the Board of Directors makes awards that may be invested by the recipient in investments deemed available under the plan. Vesting of awards under the Deferred Compensation Plan is based on the number of years of service already provided by the employee at the date of the grant. In addition, the Company has established a Voluntary Deferral Plan that provides officers of the Company the opportunity to voluntarily defer a portion of their compensation. The compensation deferred is deemed to be invested in one or more investment options available under the plan. These non-qualified plans are unfunded, although the Company does make contributions to a consolidated irrevocable rabbi trust to hedge its risks in terms of providing returns to employees on their deemed investments held in the plan.

As of December 31, 2025 and 2024, a total of $37.9 million and $48.4 million, respectively, had been recorded as long-term compensation liabilities and a total of $37.9 million and $48.5 million, respectively, had been invested under the Deferred Compensation and Voluntary Deferral plans. The change in the fair value of long-term compensation liabilities and the change in fair value of the assets invested under the Deferred Compensation and Voluntary Deferral plans was $5.1 million and $5.0 million, respectively, for the year ended December 31, 2025, $4.6 million and $4.6 million, respectively, for the year ended December 31, 2024, and $4.8 million and $4.9 million, respectively, for the year ended December 31, 2023. The Company recorded total expenses in relation to its qualified and non-qualified plans within compensation and benefits in its Consolidated Statements of Operations for the years ended December 31, 2025, 2024 and 2023 of $9.2 million, $8.5 million and $5.5 million, respectively.

**18) Equity-based Compensation**

**Cash-settled Acadian LLC awards**

The Company maintains a compensation arrangement with Acadian LLC whereby in exchange for continued service, Acadian LLC equity is either purchased by, or granted to Acadian LLC key employees subject to a limit imposed by the Company, and may be repurchased either by Acadian LLC key employees or by the Company at a future date at the then applicable fair value, subject to service requirements having been met. Compensation expense is recognized over the requisite service period equal to the cumulative vested fair value of the award at the end of each period up to the vesting date.

The Company accounts for the arrangement as "cash-settled" share-based payments, and accordingly a corresponding share-based payment liability is recorded. The fair value of the liabilities are determined with the assistance of third party valuation specialists using discounted cash flow analyses, which incorporate assumptions for the forecasted earnings information, market risk adjustments, discount rates, when award holders maximize value and post-vesting restrictions. Vested Acadian LLC liability-classified equity awards are revalued at each period end until settlement date, with changes in the liabilities included within compensation expense.

The following table presents the changes in the share-based payments liability for the years ended December 31 (in millions):

---

| | | | |
|:---|:---|:---|:---|
| | **2025** | **2024** | **2023** |
| **Balance, beginning of period** | $**25.4** | $**23.0** | $**19.4** |

**Equity-settled corporate awards**

***Acadian Asset Management Inc. equity incentive plan***

The Company has established various plans under which it is authorized to grant restricted stock awards ("RSAs"), restricted stock units ("RSUs"), performance-based restricted stock awards ("Performance-based RSAs"), performance-based restricted stock units ("Performance-based RSUs") and stock option awards. These plans are maintained to provide equity-based compensation arrangements to employees and non-executive directors. Equity ownership encourages employees and directors to act in the best long-term interests of the Company. As of December 31, 2025, the Company had 4.5 million shares of common stock available to be granted under the various plans.

Compensation expense recognized by the Company for the years ended December 31, 2025, 2024 and 2023 in relation to these awards was $3.0 million, $0.9 million, and $1.2 million respectively. The related income tax benefit recognized for years ended December 31, 2025, 2024 and 2023 was $0.1 million, $0.1 million and $0.2 million respectively. Unamortized compensation expense related to unvested RSUs at December 31, 2025 of $7.3 million is expected to be recognized over a weighted-average period of 1.9 years. The service inception date for annual awards granted in 2025 is deemed to be January 1, 2024. It is anticipated that annual awards for 2025 with a fair value of $8.8 million will be granted during 2026 with a service inception date of January 1, 2025.

**20) Derivatives and Hedging**

**Cash flow hedge**

In July 2015, the Company entered into a series of $300.0 million notional Treasury rate lock contracts which were designated and qualified as cash flow hedges. The Company documented its hedging strategy and risk management objective for this contract in anticipation of a future debt issuance. The Treasury rate lock contract eliminated the impact of fluctuations in the underlying benchmark interest rate for future forecasted debt issuances. The Company assessed the effectiveness of the hedging contract at inception and on a quarterly basis thereafter. The forecasted debt issuances occurred in July 2016 and the Treasury rate lock, which had an accumulated fair value of $(34.4) million, was settled.

On December 1, 2025, the Company completed the full redemption of the $275 million aggregate principal amount outstanding of its 4.80% Senior Notes due July 27, 2026. As a result of this transaction, amortization of $2.7 million (of the $6.3 million interest expense reclassified to earnings for the year ended December 31, 2025) was accelerated and reclassified to earnings as interest expense.

As of December 31, 2025, there was no balance relating to the cash flow hedge recorded in accumulated other comprehensive income (loss) before tax. The Company reclassified $6.3 million, $3.6 million and $3.4 million for the years ended December 31, 2025, 2024 and 2023, respectively.

**21) Segment Information**

The Company has the following 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.

The corporate holding company ("Hold Co") is included within the *Unallocated Corporate expenses* category. The Hold Co expenses are not allocated to the Company's business segment, but the Chief Operating Decision Maker ("CODM") does consider the cost structure of the corporate head office when evaluating the financial performance of the segment. The CODM is the Company's Chief Executive Officer.

**Performance Measure**

The primary measure used by the CODM in measuring performance and allocating resources to the segment is economic net income ("ENI"). ENI is used to make resource allocation decisions, determine appropriate levels of investment or dividend payout, manage balance sheet leverage, determine variable compensation and equity distributions, and incentivize management. The Company defines ENI for the segment as ENI revenue less ENI operating expenses. The ENI adjustments to U.S. GAAP include both reclassifications of U.S. GAAP revenue and expense items, as well as adjustments to U.S. GAAP results, primarily to exclude non-cash, non-economic expenses recognized under U.S. GAAP. This measure supplements and should be considered in addition to, and not in lieu of, the Consolidated Statements of Operations prepared in accordance with U.S. GAAP. The Company does not disclose total asset information for its reportable segment as the information is not reviewed by the CODM.

## Exhibit 4.3

**DESCRIPTION OF REGISTRANT'S SECURITIES**

The following description of the capital stock of Acadian Asset Management Inc. (the "**Company**") is a summary. This summary is subject to the General Corporation Law of the State of Delaware (the "**DGCL**") and the complete text of the Company's Amended and Restated Certificate of Incorporation, filed on July 12, 2019, as amended (the "**Certificate of Incorporation**"), and the Company's Amended and Restated Bylaws, adopted on May 13, 2025, as amended (the "**Bylaws**"), which are incorporated herein by reference. We encourage you to read that law and those documents carefully.

***Authorized Capital Stock***

The Company's Certificate of Incorporation authorizes 230 million shares of common stock, par value $0.001 per share (the "**Common Stock**"), and 10 million shares of preferred stock, par value $0.001 per share.

**COMMON STOCK**

***Voting Rights***

Each holder of Common Stock is entitled to one vote for each share on all matters submitted to a vote of the stockholders, including the election of directors in uncontested elections. The Company's stockholders do not have cumulative voting rights in the election of directors. Accordingly, in an uncontested election, holders of a majority of the voting shares are able to elect all of the directors.

***Dividends***

Subject to preferences that may be applicable to any then outstanding preferred stock, holders of Common Stock will be entitled to receive dividends, if any, as may be declared from time to time by the Company's board of directors out of legally available funds. Dividends may be paid in cash, in property or in shares of Common Stock. Declaration and payment of any dividend will be subject to the discretion of the Company's board of directors. The time and amount of dividends will depend upon the Company's financial condition, operations, cash requirements and availability, debt repayment obligations, capital expenditure needs, restrictions in the Company's debt instruments, industry trends, the provisions of Delaware law affecting the payment of distributions to stockholders and any other factors the Company's board of directors may consider relevant.

***Liquidation***

In the event of the Company's liquidation, dissolution or winding up, holders of Common Stock will be entitled to share ratably in the net assets legally available for distribution to stockholders after the payment of all of the Company's debts and other liabilities and the satisfaction of any liquidation preference granted to the holders of any then outstanding shares of preferred stock.

***Rights and Preferences***

Holders of Common Stock have no preemptive, conversion, subscription or other rights, and there are no redemption or sinking fund provisions applicable to Common Stock. The rights, preferences and privileges of the holders of Common Stock will be subject to and may be adversely affected by the rights of the holders of shares of any series of the Company's preferred stock that the Company may designate in the future.

***Fully Paid and Nonassessable***

All outstanding shares of Common Stock of the Company are fully paid and non-assessable.

------

***Stock Exchange Listing***

The Common Stock is listed on the NYSE under the symbol "AAMI."

***No Sinking Fund***

Shares of the Common Stock have no sinking fund provisions.

***Transfer Agent and Registrar***

The transfer agent and registrar for the Company's Common Stock is Computershare Trust Company, N.A. The transfer agent and registrar's address is P.O. BOX 43006, Providence, RI, 02940-3006.

***Anti-Takeover Effects of Provisions of the Company's Certificate and Bylaws and Delaware Law***

Some provisions of Delaware law and the Company's Certificate of Incorporation and Bylaws could make the following transactions difficult: acquisition of the Company by means of a tender offer; control of the Company's board of directors by means of a proxy contest or otherwise; or removal of incumbent officers and directors of the Company. It is possible that these provisions could make it more difficult to accomplish or could deter transactions that stockholders may otherwise consider to be in their best interest or in the best interests of the Company, including transactions that might result in a premium over the market price for the Company shares.

These provisions, summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of the Company to first negotiate with the Company's board of directors. The Company believes that the benefits of protection to the Company's potential ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure the Company outweigh the disadvantages of discouraging these proposals because negotiation of these proposals could result in an improvement of their terms.

*Undesignated Preferred Stock*

The ability to authorize undesignated preferred stock will make it possible for the Company's board of directors to issue preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of the Company. These and other provisions may have the effect of deterring hostile takeovers or delaying changes in control or management of the Company.

*Special Stockholder Meetings*

The Bylaws provide that a special meeting of stockholders may be called only by the Company's board of directors or by one or more stockholders holding at least 10% of the total number of issued and outstanding Common Stock of the Company.

*Requirements for Advance Notification of Stockholder Nominations and Proposals*

The Bylaws of the Company establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the Company's board of directors or a committee of the Company's board of directors.

*Composition of the Board of Directors; Election and Removal of Directors; Filling Vacancies*

------

The Company's board of directors consists of not less than five nor more than seven directors. In any uncontested elections of directors, a director nominee for the Company's board of directors will be elected by the affirmative vote of a majority of the votes cast with respect to such director by the shares represented and entitled to vote at a meeting of the stockholders for the election of directors at which a quorum is present, voting together as a single class. The directors of the Company are elected until the expiration of the term for which they are elected and until

their respective successors are duly elected and qualified. Pursuant to the Stockholder Agreement, dated May 17, 2019, between the Company and Paulson & Co. Inc. ("Paulson & Co."), Paulson & Co. has the right to nominate

one director to the board of directors of the Company's Board of Directors (subject such nominee's election by the

stockholders of the Company) until such time as Paulson & Co. does not own at least 7% of the total number of

issued and outstanding Common Stock of the Company.

The directors of the Company may be removed by the affirmative vote of at least a majority of the holders of the

Company's then-outstanding Common Stock. Furthermore, any vacancies on the Company's board of directors,

through death, resignation, removal, an increase in the number of directors or otherwise may be filled by a majority

of the directors then in office, even though less than a quorum, or by a sole remaining director. This system of

electing and removing directors may tend to discourage a third party from making a tender offer or otherwise

attempting to obtain control of the Company, because it generally makes it more difficult for stockholders to replace

a majority of the directors.

*Choice of Forum*

The Company's Certificate of Incorporation provides that, unless the Company consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the exclusive forum for: any derivative action or proceeding brought on the Company's behalf; any action asserting a breach of fiduciary duty; any action asserting a claim against the Company arising pursuant to the DGCL; or any action asserting a claim against the Company that is governed by the internal affairs doctrine. The Certificate of Incorporation provides that the exclusive forum provision will not preclude or contract the scope of exclusive federal or concurrent jurisdiction for actions brought under the Securities Exchange Act of 1934, as amended, or the Securities Act of 1933, as amended, or the respective rules and regulations promulgated thereunder. Although the Company's Certificate of Incorporation contains the choice of forum provision described above, it is possible that a court could find that such a provision is inapplicable for a particular claim or action or that such provision is unenforceable.

***Amendment of the Certificate and Bylaws***

The amendment of any of the provisions in the Certificate of Incorporation requires approval by a stockholder vote by the holders of at least 75% of the voting power of the then outstanding voting stock. The Bylaws of the Company may be amended by the board of directors or by the holders of at least 75% of the voting power of the then outstanding voting stock.

**PREFERRED STOCK**

The Certificate of Incorporation authorizes the board of directors of the Company to issue preferred stock in one or more series and to determine the preferences, limitations and relative rights of any shares of preferred stock that it shall choose to issue, without vote or action by the stockholders.

ACADIAN ASSET MANAGEMENT INC.

INSIDER TRADING POLICY

February 26, 2026

------

Why does Acadian Asset Management Inc. have a Policy on Insider Trading?

Acadian Asset Management Inc. ("AAMI") adopted this policy on Insider Trading to reduce the risk that any AAMI employee or Director might be found to have engaged in insider trading in AAMI securities in violation of securities laws. Insider trading may result in unfair advantage or manipulation of the market in AAMI's securities and may adversely affect the value of AAMI's securities. It may also expose you and AAMI to potential liability. This policy sets parameters for when trading in AAMI's securities is not permitted or appropriate and is not intended to impose on AAMI or you any civil, criminal or other liability that would not otherwise exist. It is not intended to be a comprehensive review of the laws on insider trading. In addition, it is the policy of AAMI to comply with all applicable securities laws when transacting in its own securities.

*Please do not hesitate to contact AAMI Legal with any questions you have about this policy.*

Who Should Comply with this Policy?

The requirements of this policy apply to AAMI employees, officers and Directors. In addition, under certain circumstances, other individuals who work with AAMI or an AAMI Affiliate may also be required to comply with this policy (e.g., temporary workers and consultants). AAMI Legal will notify such individuals when, and if, they are required to comply. The trading restrictions in this policy apply to the purchase or sale of AAMI's securities for any fiduciary account (e.g., trustee, executor, custodian) where you make the investment decision even when you do not have a pecuniary interest in the securities held in the account.

*If you know or have reason to believe that this policy has been or is about to be violated, you should bring the actual or potential violation to the attention of AAMI Legal immediately.*

What is Insider Trading?

The Securities and Exchange Commission and other regulators are very effective at detecting and pursuing insider trading cases and they have aggressively prosecuted insider traders and tippers. Any person who engages in insider trading or tipping (as discussed below) can face a substantial jail term (up to 20 years), civil penalties of up to three times the profit gained (or loss avoided) by that person and/or his or her "tippee," and criminal fines of up to $5,000,000. In addition, if it is found that AAMI failed to take appropriate steps to prevent insider trading, AAMI may be subject to significant criminal fines and civil penalties of up to $1,000,000 or, if greater, three times the profit gained (or loss avoided) as a result of the insider trading.

---

| | |
|:---|:---|
| *Material Nonpublic Information, or "MNPI"* | Material nonpublic information relevant to a security. Whether a particular item is "material" or "nonpublic" will be judged with 20-20 hindsight. Accordingly, when in doubt as to a particular item of information, you should presume it to be material and not to have been sufficiently disclosed to the public. Do not hesitate to contact AAMI Legal with any questions you may have. |
| *Insider Trading* | Buying or selling any securities while in possession of material nonpublic information. |
| *Material Information* | If there is a substantial likelihood that a reasonable investor would consider the information significant in making an investment decision or the information could reasonably be expected to have a substantial effect on the price of AAMI's securities. Material information can be positive or negative and can relate to virtually any aspect of AAMI's business. |
| *Nonpublic Information* | Information is "nonpublic" as to a security until it has been effectively communicated to the marketplace through a press release, SEC filing or other appropriate media and enough time has elapsed to permit the investment market to absorb and evaluate the information. If there is any doubt whatsoever as to whether information has been effectively communicated to the marketplace, such information should be considered nonpublic until such time as there is no doubt. |
| *Tipping* | To communicate material nonpublic information to others who buy or sell any securities on the basis of such information. |

---

*Examples of events or developments that should be presumed to be material with respect to AAMI's securities would be:*<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• knowledge of a trend in AAMI's revenues, earnings, or assets under management not yet fully disclosed to the public;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• acquisition, material loss, or regulatory action with respect to AAMI or an AAMI Affiliate;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• significant legal exposure due to actual, pending or threatened litigation;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a purchase or sale of substantial assets;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in senior management or other major personnel changes;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in dividend policy, declaration of a share split or the offering of additional securities; and<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in AAMI's auditors or a notification from its auditors that AAMI may no longer rely on the auditor's audit report.<br>*These examples are illustrative only; many other types of information may be considered material, depending on the circumstances. The materiality of particular information should be reevaluated on a regular basis.*<br>

------

Activities You Should Avoid

• <u>Trading on Material Nonpublic Information</u>: You should not trade in AAMI's securities (including purchases and sales of AAMI's securities, options, warrants, puts, calls and other derivative securities) or enter into a written plan for the purchase or sale of AAMI's securities (a "Planned Sale Program") when you possess information about AAMI or an AAMI Affiliate that could potentially constitute material nonpublic information, and should not communicate, or "tip" the information to any third party, except to persons who have a legitimate need to know such information and understand their obligation not to trade on it. You should not have others trade in AAMI's securities on your behalf while you are in possession of material non-public information. Further, you may not use knowledge about any client securities recommendations, holdings or transactions (or potential transactions), or nonpublic information about another company obtained in the course of your work for AAMI, for personal profit.

• <u>Trading During a Blackout Period</u>: You, your spouse and members of your immediate family sharing your household should not trade in AAMI's securities (including purchases, sales, gifts, loans, pledges, hedges, contributions to a trust, or any other transfers) or enter into a Planned Sale Program during the following blackout periods:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ the period beginning the last trading day of each quarter and ending at the close of trading two full trading days after the release of AAMI's quarterly or annual earnings results following that quarter; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ any other period designated by AAMI Legal as a period during which you should not engage in any transaction involving AAMI's securities.

A "trading day" is any day when the New York Stock Exchange is open for trading.

• <u>Trading during a Retirement Plan Blackout Period</u> *<u>(AAMI Directors and Executive Officers Only)</u>*: As an AAMI Director or Executive Officer, you should not trade in AAMI equity securities acquired in connection with your service as a director or executive officer during any period that has been designated by AAMI as a Retirement Plan Blackout Period. There are limited exceptions, and AAMI Directors and Executive Officers should consult with AAMI Legal prior to attempting to trade in AAMI's equity securities.

---

| <u>KEY TAKEAWAYS</u> |
| Do not trade in AAMI shares when in possession of MNPI |
| Do not transact in any security when you possess MNPI |

• <u>Short Sales</u>: You, your spouse and members of your immediate family sharing your household should not sell short shares of AAMI. Short sales involve transactions in which you do not own AAMI's securities at the time of the sale as well as those in which you own AAMI's securities but plan to deliver securities other than your own securities in connection with the sale of AAMI's securities (a.k.a. selling short against the box). You, your spouse and members of your immediate family sharing your household should not buy put or sell call options on AAMI's securities when they do not own at least the number of securities underlying the option. This restriction does not apply to "variable prepaid forward" contracts or similar arrangements that have been precleared by AAMI Legal.

What You Need to Do

• <u>Obtain Pre-Clearance</u>: You, your spouse and members of your immediate family sharing your household should obtain clearance prior to (i) engaging in any transaction involving AAMI's securities and/or (ii) entering into a Planned Sale Program. AAMI employees, other than Section 16 Officers or Directors, should obtain clearance from AAMI Legal. Section 16 Officers who are not Directors should obtain clearance from the Chair of the Audit Committee (the "Audit Committee") of the AAMI Board of Directors (the "Board"). AAMI Directors should obtain approval from the Chair of the Board. Each proposed transaction or entry into a Planned Sale Program will be evaluated to determine if it raises insider trading concerns or other concerns under federal or state securities laws and regulations. AAMI Legal, the Chair of the Audit Committee or the Chair of the Board, as applicable, may disapprove the transaction or entry into the Planned Sale Program if it is determined that it could result in a violation of this Policy. Any advice provided by AAMI Legal, the Chair of the Audit Committee or the Chair of the Board to you will relate solely to the restraints imposed by law and will not constitute investment advice. Clearance of a transaction or entry into a Planned Sale Program is generally valid only for a period of two trading days unless AAMI Legal, the Chair of the Audit Committee or the Chair of the Board, as applicable, has specified in writing an alternate period of validity (not to exceed five trading days). If the transaction order is not placed or the Planned Sale Program is not entered into, as applicable, within that two-trading-day period (or other period designated by AAMI Legal, the Chair of the Audit Committee or the Chair of the Board, as applicable), clearance should be re-requested. If pre-clearance is denied, you should keep the information pertaining to the denial confidential. Any pre-clearance granted by AAMI Legal, the Chair of the Audit Committee or the Chair of the Board, as applicable, may be withdrawn at any time upon notice to you. <u>Any request for pre-clearance may be denied by AAMI Legal, the Chair of the Audit Committee or the Chair of the Board, as applicable, for any or no reason. Notwithstanding the pre-clearance of any request, AAMI (including AAMI Legal, the Chair of the Audit Committee and the Chair of the Board) assumes no liability for the consequences of any transaction made pursuant to such request.</u>

Even if you have received pre-clearance or are not required to obtain pre-clearance, neither you, your spouse nor any member of your immediate family sharing your household may trade in any securities (including options and other derivative securities) of AAMI or enter into a Planned Sale Program if you or such other person is in possession of material nonpublic information about AAMI (or material, nonpublic information regarding an AAMI affiliate that could potentially constitute material nonpublic information at the AAMI level).

------

• <u>Maintain Confidentiality</u>: You should maintain the confidentiality of AAMI and AAMI Affiliate internal information and may only release internal information to authorized persons for authorized business purposes. Unauthorized disclosure of internal information about AAMI, whether or not for the purpose of facilitating improper trading in AAMI's securities, may cause AAMI serious problems. As a public company, AAMI is required under Regulation Fair Disclosure of the federal securities laws to avoid the selective disclosure of material nonpublic information.

• <u>Report Violations</u>: You should promptly report any violations of this policy to AAMI Legal.

• <u>Report Section 16 Transactions</u> *<u>(AAMI Directors and Section 16 Officers Only)</u>*: As an AAMI Director or Officer who has been designated a "Section 16 Officer" by AAMI Legal, you should immediately report changes of beneficial ownership in AAMI's equity securities (including purchases, sales, option exercises, security/option grants, gifts, transfers, pledges, 10b5-1 Plan transactions, restricted security grants, and most other equity compensation transactions) to AAMI Legal so that a Form 4 may be electronically filed with the Securities and Exchange Commission before the end of the second business day following the transaction date.

Exceptions to the General Policy

• <u>Rule 10b5-1 Planned Sale Programs</u>: In the event you have entered into a Planned Sale Program (as described below) in compliance with this policy, the above requirement to "Obtain Pre-Clearance" and the "Trading During a Blackout Period" prohibition do not apply to transactions in AAMI's securities pursuant to the terms of such Planned Sale Program.

A Planned Sale Program, or, a "10b5-1 Plan" is a contract, instruction or written plan that sets forth a plan to sell securities in the future without any further investment decision(s) at the time of the actual consummation of the trade.

A 10b5-1 Plan must be established (or amended, as the case may be) in good faith at a time when you were not aware of material nonpublic information, and you must act in good faith with respect to the 10b5-1 Plan. In addition, any modification or change to the amount, price or timing of a trade under a 10b5-1 Plan constitutes the adoption of a new 10b5-1 Plan with such modified terms.

Any document intended to qualify as a 10b5-1 Plan must adhere to the requirements of Rule 10b5-1 of the Exchange Act, including the restrictions set forth below, and such document (including any amendments or modifications thereof) must be pre-cleared by AAMI Legal in advance of adoption, amendment or modification.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ *Cooling-Off Period.* Each 10b5-1 Plan must provide for a cooling-off period prior to the commencement of trading thereunder. If you are a director or officer (as defined in Section 16 of the Exchange Act), the cooling-off period must expire no earlier than the later of (i) ninety (90) days following adoption of the plan or (ii) two (2) business days after the filing of AAMI's Form 10-K or Form 10-Q that includes financial results for the quarter during which the plan was adopted, subject to a maximum cooling-off period of one hundred twenty (120) days after adoption of the plan. If you are not a director or officer, the cooling-off period must be at least thirty (30) days after adoption of the plan. In addition, in the event of any modification or change to the amount, price or timing of a trade under a 10b5-1 Plan, a new cooling-off period as described above will be required between such modification or change and the first possible transaction under such revised plan or any new plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ *No Overlapping Plans.* No person entering into a 10b5-1 Plan may have a separate 10b5-1 Plan outstanding, except a person may (i) use multiple brokers to effect transactions that, when taken together, satisfy the requirements for a 10b5-1 Plan, (ii) maintain another 10b5-1 Plan so long as transactions under the later-commencing plan cannot begin until after all transactions under the earlier-commencing plan have been completed or expire without completion and the applicable cooling-off period is satisfied, treating the termination of the earlier-commencing plan as the date of adoption of the later-commencing plan, or (iii) adopt a second plan that only allows sales that are

------

necessary to satisfy tax withholding obligations that arise from the vesting of a compensatory award and such person does not exercise control over the timing of such sales.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ *Limitation on Single Trade Plans.* No person may adopt a 10b5-1 Plan that contemplates only a single transaction if such person had adopted a plan contemplating only a single transaction within the prior twelve (12) months.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ *Certification by Directors and Officers.* Directors and officers (as defined in Section 16 of the Exchange Act) must include a representation in the 10b5-1 Plan certifying that, on the date of adoption of the plan, such director or officer is not aware of material nonpublic information about AAMI or its securities and such director or officer is adopting the 10b5-1 Plan in good faith and not as part of a plan or scheme to evade the prohibitions of Exchange Act Section 10(b) and Exchange Act Rule 10b-5.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ *Information Provided by Directors and Officers.* Each quarter, AAMI is required to publicly disclose when directors or officers adopt or terminate 10b5-1 Plans and provide a description of the material terms of each plan, including the name of the director or officer, the date of adoption or termination, the duration and the aggregate number of securities to be purchased or sold (however, the price at which the person executing the plan is authorized to trade does not need to be publicly disclosed). Therefore, directors and officers (as defined in Section 16 of the Exchange Act) must provide AAMI Legal with a final executed copy of, and any amendments to, (i) any 10b5-1 Plan and (ii) any other adopted written arrangement for trading the AAMI's securities, in each case within two business days of the adoption or amendment thereof. In addition, directors and officers (as defined in Section 16 of the Exchange Act) must notify AAMI Legal of any termination of any 10-b5-1 Plan or such other written securities trading arrangement promptly upon termination.

• <u>Exception for Certain Transfers</u>: The above "Trading During a Blackout Period" prohibition does not apply to *bona fide* gifts of AAMI's securities by you to a trust formed for estate-planning purposes or a family limited partnership, charitable foundation or similar entity, if investment and voting decisions of the organization are controlled by you, as transferor, and you have confirmed in writing that you: (1) will not permit the transferee to sell or otherwise transfer AAMI's securities while you are in possession of material nonpublic information or during a Blackout Period and (2) will notify AAMI Legal of the transfer.

• <u>Transactions under AAMI Benefit Plans</u>: This Policy does not apply to the following transactions under AAMI benefit plans, except as noted below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ <u>Stock Option Exercises</u>: This Policy's trading restrictions generally do not apply to the exercise of a stock option nor do they apply to the cashless exercise of an option through AAMI. The trading restrictions do apply, however, to any sale of the underlying stock or to a cashless exercise of the option through a broker, as this entails selling a portion of the underlying stock to cover the costs of exercise.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ <u>Restricted Stock Units</u>: This Policy's trading restrictions do not apply to the vesting of restricted stock units, or the exercise of a right to have AAMI withhold shares to satisfy tax withholding consequences of vesting. This Policy does apply, however, to market sales of any shares received.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ <u>401(k) Plan</u>: This Policy's trading restrictions do not apply to purchases of securities in AAMI's 401(k) plan as a result of any periodic contributions made pursuant to payroll deductions.

• <u>Transactions in "Broad Basket" Funds:</u> Transactions in mutual funds, exchange-traded funds, index funds or other "broad basket" funds that own or hold AAMI's securities as one of many investments are not subject to this Policy.

• <u>Other Exceptions:</u> AAMI's Chief Legal Officer may make exceptions to this Policy, as he/she deems appropriate and in compliance and accordance with legal and regulatory requirements.

------

Responsibilities of AAMI Legal

• <u>Oversight of this Policy</u>: AAMI Legal is responsible for overseeing compliance with this policy. Waiver of any provision of this policy may be authorized in writing by the Chief Legal Officer, and any waivers shall be reported to the AAMI Board at its next regularly scheduled meeting.

• <u>Maintain Records</u>: AAMI Legal will maintain records required by this policy consistent with AAMI's Records and Information Management policy.

• <u>Maintain Your Privacy</u>: AAMI Legal recognizes that information collected under this policy is sensitive and private and will use its best efforts to properly handle and safeguard it. Only authorized persons are permitted access to your information. It is also possible that information may be requested in connection with regulatory examinations or for other legitimate purposes and AAMI reserves the right to comply with such requests.

• <u>Training</u>: AAMI Legal is responsible for periodically training AAMI employees and directors on the prohibitions and requirements under this policy.

• <u>Determine Sanctions</u>: AAMI Legal will consult with executive management, if necessary, to evaluate and resolve violations of this policy. If you violate this policy, you may be subject to sanctions, including one or more of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ a letter to your personnel and/or personal trading file;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ suspension or termination of employment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ a fine; and/or
