How it makes money

Almost all revenue is commission and fee income earned when a policy is placed or renewed. Of $5,902 million of total 2025 revenues, $5,763 million were commissions and fees and $139 million investment and other income; within commissions and fees, $255 million were profit-sharing contingent commissions — variable payments from insurers that depend on the volume, growth and loss experience of the business placed with them. Commissions are usually a percentage of the premium, so revenue moves with insurance pricing and with the size of the exposure insured, not with the number of hours worked. Fee business is charged directly to clients for services, and the flood and program operations earn policy administration fees. The company also earns investment income on fiduciary cash held between collecting premiums and remitting them to carriers.

Revenue by segment

Brokerage revenue is renewal-based: once an account is placed, the incumbent broker holds the client's loss history, policy structure and carrier relationships, and moving broker mid-programme is disruptive, which makes retention high and new-business capture slow for competitors. The Specialty Distribution side adds underwriting authority delegated by insurers, which a new entrant cannot simply buy. These advantages are real but not impregnable: the filing itself lists disintermediation, increased competition and the loss of insurance-company relationships among its risk factors, and growth has depended heavily on acquiring other brokers rather than on organic barriers alone.

Insurance is bought in good times and bad — a business cannot legally or practically operate uninsured — so the volume of policies is fairly stable. What moves is the price: commissions are a percentage of premium, so revenue rises when property & casualty rates harden and falls when the market softens, and it also follows the exposures being insured (payrolls, fleet sizes, property values, construction activity), which shrink in a downturn. The company explicitly lists economic slowdown, inflation and interest rates, and fluctuation in commission revenue among its risks; profit-sharing contingent commissions are the most volatile piece, since a bad catastrophe year cuts them. Investment income on fiduciary funds moves directly with short-term interest rates.

Key risks

• Acquisitions may not deliver what was assumed — The company discloses that it may fail to realise the anticipated benefits of acquisitions, that the assumptions underlying a transaction may prove inaccurate, and that integrating acquired businesses — including their cultures, systems and controls — is a continuing challenge.
• Debt taken on to finance deals — Risk factors cover financing-related risks and increased indebtedness, the need to comply with debt covenants, exposure to credit-market changes and to a possible credit-rating downgrade, as well as dilution from issuing equity.
• Loss of people and of insurer relationships — The filing flags dependence on retaining employees and key personnel, changes in culture and management, and the risk of losing relationships with insurance companies and other intermediaries on whose capacity the business depends. Reduced insurer capacity is listed separately.
• Commissions fluctuate with premium rates and catastrophes — Disclosed risks include fluctuation in commission revenue and in the timing of commissions, the effect of natural disasters on profit-sharing contingent commissions, claims expense in the captive insurance operations, and the effect of inflation and interest rates.
• Cyber attacks and dependence on third parties — The company lists cybersecurity attacks and IT disruption, dependence on third-party vendors, disclosure of confidential information, and compliance with data-privacy and protection rules among its risk factors.
• Regulation of how brokers are paid — Risk factors include regulatory uncertainty over compensation arrangements, claims and regulatory proceedings, compliance with non-U.S. law, changes to federal government programmes (which matter for the flood business), and tort reform reducing demand for liability insurance.
• Concentrated shareholder control and goodwill — The filing notes concentration of shareholder control, the limits of internal controls in preventing fraud, and the risk of goodwill impairment and of changes in accounting estimates — goodwill being large after years of acquisitions.

There is no meaningful concentration. The filing states that no material part of the Retail segment is attributable to a single customer or a few customers, and that in 2025 the largest single Retail customer represented 0.6% of that segment's commissions and fees. In Specialty Distribution the largest customer represented approximately 7.2% of the segment's commissions and fees. The company does not disclose a combined top-customers share for the group, so no consolidated figure is given here.
