Risk factors and legal proceedings
The risks Acadian Asset Management Inc. names in Item 1A of its 10-K filed Feb 27, 2026: 38 risks under these headings, as written.9
- Risks Related to Operations
- Our overall financial results are dependent on the ability of Acadian LLC to generate earnings.
- 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.
- We derive a substantial portion of our revenue from a limited number of investment strategies.
- 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.
- We rely on certain key personnel, and our results are dependent upon our ability to retain and attract key 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.
- Reputational harm could result in a loss of assets under management and revenues.
- We may not always successfully manage actual or potential conflicts of interests that may arise in our business.
- Impairment of our relationships with clients and/or consultants may negatively impact our business and 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.
- Pressure on fee levels and changes to mix of assets could impact our results of operations.
The other 27 risks
- If our techniques for managing risk are ineffective, we may be exposed to material unanticipated losses.
- We may be exposed to potential liability as a general partner or a controlling person.
- Our expenses are subject to fluctuations that could materially impact our results of operations.
- Losses on our seed capital could adversely impact our results of operations or financial condition.
- The cost of insuring our business is meaningful and may increase.
- 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 outstanding indebtedness may impact our business and may restrict our growth and results of operations.
- We may be unable to obtain sufficient capital and liquidity to meet the requirements of our business.
- Our business involves risks of potential litigation that could harm our business.
- 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 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.
- The failure of a counterparty to meet its obligations could affect our business adversely.
- 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.
- Risks Related to Our Industry
- We operate in a competitive environment.
- 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.
- 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.
- Risks Related to Our Ownership Structure and Governance
- Paulson has 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.
- 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.
- 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.
- 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.
- 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.
- Changes in tax laws could have an adverse impact on our business, financial condition, and results of operations.
- General Risk Factors
- The market price of our common stock and the broader equity markets have been, and may continue to be, volatile.
- 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.
- 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.
- Our management devotes substantial time to compliance with our public company legal and reporting obligations.
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.
