Risk Radar (year-over-year Risk Factors)

← All Risk Radar

Fiscal period ending 2025-12-31 versus 2024-12-31view filing on EDGAR →

The resolution of AssuredPartners and related M&A integration risks is the dominant easing, but it is offset by a broad worsening across regulatory, cyber, operational, and macro themes. New AI-driven cybersecurity threats, a 20% surge in healthcare costs, expanded litigation exposure from anti-DEI and anti-competitive allegations, and heightened governance risks collectively represent a substantive deterioration in the non-M&A risk profile. The net picture is mixed, with the M&A cleanup masking a meaningful accumulation of new and escalated risks elsewhere.

Company-specific changes

New

New disclosure of material third-party service provider dependency risk, including operational disruption, reputational harm, and regulatory/contractual penalties.

Our business or reputation could be harmed by our reliance on third-party providers. While we maintain some of our critical information technology systems, we are dependent on third-party providers…

Revised

Health care costs surged 20% year-over-year, a material escalation in a key cost driver. Specific quantification of this increase is substantive new information.

Sustained increases in compensation expense and the cost of employee benefits could reduce our profitability. Compensation expense and the cost of employees’ medical and other employee benefits…

Removal of Pillar 2 discussion and IRC Section 29 tax credit exposure ($108M) eliminates disclosure of material tax risks, worsening transparency on contingent liabilities.

Revised

Added explicit disclosure of larger acquisition integration risks, including AssuredPartners (largest acquisition), technology diversion, and unmet synergy assumptions.

Revised

Revised

New disclosure of cybersecurity and physical threats to senior management escalates governance risk. Addition of CFO to succession planning scope and Wyoming non-compete restrictions also worsen talent retention risk.

Our success depends, in part, on our ability to attract and retain qualified talent, including our senior management team. We depend upon members of our senior management team, who possess extensive…

Revised

International revenue declined from 36% to 33%. Geopolitical risks expanded to explicitly include Latin America and Caribbean conflicts alongside Russia-Ukraine and Middle East tensions.

Our substantial operations outside the U.S. expose us to risks different than those we face in the U.S. In 2025, we generated approximately 33% of our combined brokerage and risk management revenues…

Material year-over-year changes to this company's Risk Factors (Item 1A), found by comparing each annual report to the prior year, judged for materiality, and classified as company-specific or common-mode against the cross-company catalog. Common-mode changes are the macro themes many companies disclose in common; they are collapsed above. A filing marked unchanged had no material change from the prior year; its summary describes the company's standing risks, which remain in force. Fiscal periods are the reporting period ends. Not investment advice.
