Negatives

• Fiduciary interest income decreased by $94 million to $403 million in 2025, attributed to lower average interest rates.

• Unrecognized actuarial losses for non-U.S. pension plans increased by $389 million to $3.9 billion at December 31, 2025, mainly due to lower than expected returns on plan assets and foreign exchange impact.

Risks

• Geopolitical and macroeconomic conditions, including wars, social unrest, tariffs, slower GDP growth, foreign exchange rate fluctuations, lower interest rates, capital markets volatility, inflation, and changes in insurance premium rates, could adversely affect results.
• Significant uninsured exposures from errors and omissions (E&O), breach of fiduciary duty, and other claims, including 'silent cyber' allegations, could lead to substantial liabilities and reputational harm.
• Non-compliance with U.S. federal and state or foreign laws and regulations (e.g., sanctions, anti-corruption, data privacy, cybersecurity, AI regulations) could result in investigations, penalties, and operational limitations.
• Reliance on third-party providers or introducers carries risks of non-compliance with internal policies or applicable laws, potentially harming business or reputation.
• Inability to effectively identify and manage actual and apparent conflicts of interest could lead to regulatory scrutiny and reputational damage.
• Significant liability or reputational damage could arise from breaches of information systems, failure to protect client or company data, or disruptions from cyberattacks (including ransomware, AI-driven threats, and supply chain attacks).
• Costs to comply with, or failure to comply with, evolving data privacy, data security, data protection, and AI-related laws (e.g., GDPR, CCPA, EU's AI Act) could adversely affect financial condition, operating results, and reputation.
• Business performance and growth plans could be negatively affected by an inability to develop and implement technology improvements or respond effectively to digital disruption and technological change, including AI.
• The loss of senior management or key colleagues, or failure to attract, retain, and develop talent, could materially adversely affect the business.
• Failure to maintain corporate culture could adversely affect business and reputation, increasing risks of unethical behavior or regulatory violations.
• Increasing scrutiny and changing laws regarding business responsibility practices and disclosure may impose additional costs or expose the company to new risks, including 'greenwashing' accusations.
• Significant competitive pressures in all businesses, including from disintermediation, capital market alternatives, and new entrants (e.g., Insurtech, generative AI), could impede growth.
• Reliance on a large number of vendors and other third parties for key functions exposes the company to risks from their failures, including non-compliance, service disruptions, or data breaches.
• Inability to successfully recover from disasters or business continuity problems (e.g., natural disasters, cyberattacks, power loss) could cause material financial loss, loss of human capital, regulatory actions, reputational harm, or legal liability.
• Risks associated with acquisitions and dispositions include integration challenges, failure to achieve synergies, legacy liabilities, and potential impairment of goodwill and intangible assets.
• Inability to collect receivables, particularly in challenging macroeconomic or geopolitical conditions, could adversely affect results of operations and cash flows.
• Inability to obtain sufficient financing on favorable terms, especially in an environment of rising interest rates, could limit capital access for growth and other needs.
• Defined benefit pension plan obligations are sensitive to financial markets, potentially leading to increased pension expense or additional cash payments.
• Significant non-U.S. operations expose the company to exchange rate fluctuations and various legal, economic, operational, market, compliance, and reputational risks.
• Quarterly revenues and profitability may fluctuate significantly due to various factors, including client engagements, regulatory changes, seasonality, and macroeconomic conditions.
• Credit rating downgrades would increase financing costs and could subject the company to operational risk.
• The current debt level of approximately $19.6 billion could adversely affect financial flexibility.
• Provisions in the U.S. tax regime (e.g., NCTI, BEAT, CAMT) and the OECD international tax framework (Pillar Two, Pillar One) may impact the effective tax rate and increase compliance costs.
• Inability to fully realize the benefits of the 'Thrive' program and 'Business Client Services' could affect planned growth and strategic initiatives.
• Mercer's Wealth business is subject to risks related to capital market fluctuations, third-party asset managers, operations and technology, trading errors, conflicts of interest, sustainability/greenwashing, asset performance, and regulatory compliance.
• Businesses are subject to risks related to the U.S. healthcare industry, including regulation and reputational damage from negative publicity.
• Revenues for the Consulting segment may decline due to changes in economic conditions, asset values, client financial condition, government regulation, or a shift to passively managed investments.
• Factors affecting defined benefit pension plans and related services could adversely affect Mercer.
• Profitability of the Consulting segment may decline if adequate utilization and pricing rates for consultants are not achieved or maintained.

Future Outlook

The company expects to incur approximately $500 million in costs over three years for its 'Thrive' program, with anticipated annualized savings of $400 million. Changes to U.S. corporate tax provisions under the 'One Big Beautiful Bill Act' are generally effective in 2026, and the OECD Pillar Two minimum tax rules will be fully effective in 2027. The company anticipates required contributions to its U.S. qualified pension plans of $33 million and non-U.S. defined benefit plans of $39 million in 2026. Mediation in the Greensill litigation is expected to begin in Q1 2026, with a trial scheduled for August 2026.

Management Comments

• John Q. Doyle, President and Chief Executive Officer, certified that the Annual Report on Form 10-K does not contain any untrue statement of a material fact or omit to state a material fact, and that financial statements fairly present the financial condition, results of operations, and cash flows.
• Management is responsible for establishing and maintaining adequate internal control over financial reporting, designed to provide reasonable assurance regarding reliability of financial reporting.
• Management evaluated the effectiveness of internal control over financial reporting as of December 31, 2025, and determined it was effective.

Industry Context

StockSavvy.ai notes that Marsh & McLennan's strong revenue growth and strategic investments in AI and digital solutions, such as the AI Academy and Business Client Services, position it well within a competitive and evolving professional services landscape. The company's proactive approach to brand strategy and efficiency through the 'Thrive' program reflects a broader industry trend towards digital transformation and client-centric value delivery. The increased interest expense highlights the impact of rising interest rates on highly acquisitive firms, while the decrease in fiduciary income points to challenges from a lower interest rate environment affecting certain revenue streams. The ongoing legal proceedings, particularly the Greensill litigation, underscore the heightened regulatory and litigation risks faced by large intermediaries in complex financial markets.
