About Aon plc
Primary reporting period: 2025-12-31 · Research updated Oct 12, 2026. A research update is not a new financial filing.
Who they are
Aon plc operates as a professional services firm in the United States, rest of the Americas, the United Kingdom, Ireland, rest of Europe, the Middle East, Africa, and the Asia Pacific. It operates through Risk Capital and Human Capital segments. The company offers commercial risk solutions comprising retail and insurance brokerage, specialty solutions, global risk consulting, captives management, and affinity programs; health solutions, such as consulting and brokerage, consumer benefits, and talent advisory services; and wealth solutions, including retirement consulting and investments.
How they make money
Aon provides professional services in commercial risk, reinsurance, health, wealth and human capital consulting. Its FY2025 Form 10-K describes two segments, Risk Capital and Human Capital. The company earns commissions and fees from broking, advisory, analytics and consulting work. Client retention, insured exposure, transaction volumes and compensation costs can affect margins and cash conversion.
Brands & revenue mix
No separate brand or brand-level revenue disclosure was confirmed in the reviewed sources. This does not mean the company has no brands.

Geographic revenue
No reconciled geographic revenue breakdown was confirmed for the current research period.
Customer types
Customer categories were not separately identified in the reviewed source set.
Customer concentration

Strengths
- Diversified risk and human capital services — Research interpretation: recurring client advisory needs and global distribution can support service demand, though fee rates and renewal retention vary by business.Source
Risks
- Insurance market cycles and execution — Research interpretation: premium cycles, client demand, competition, regulation and integration costs can influence commissions and operating margins.Source

Company-specific research
Questions worth answering for AON
These questions are generated from this company's current financial and score data so the page adds context instead of treating the headline score as a stand-alone conclusion.
- •Can AON maintain its current revenue growth rate and improve the amount of that revenue that turns into earnings and cash?
- •Is AON's positive free cash flow repeatable, or is the current level being helped by temporary working-capital or spending changes?
- •Is AON's debt load manageable relative to cash generation, interest costs and upcoming maturities?
- •Is AON's valuation discount tied to a temporary concern or to a longer-term business risk?

Momentum & Volatility Signals
Two different market-behavior signals. Momentum measures direction and trend strength. Volatility measures how large and unstable the price moves are, regardless of direction.
Building upward momentum
Low movement
A high momentum score means price has been trending upward with confirming short- and medium-term strength. A low score means downward or weakening momentum.
A high volatility score means larger, less stable price swings. It can happen while a stock is rising or falling, so high volatility is not automatically bullish or bearish.
Important: the volatility score above is based on realized price volatility. Implied volatility (IV) comes from options prices and represents the market's expected future movement. Wall Street Score will keep IV separate and will only display it when a verified options-chain feed is available.
