The Ethical Read
Why It Falls Short, in Plain English
Aon does not clear the screen at the business-activity stage. It operates in conventional financial services, which the screen treats as interest-based, so the financial ratios are not the deciding factor here.
Read as at 2026-10-28. It updates when the underlying figures move, and past reads are kept below.

What the Numbers Say It Is Worth
The Fair Value Range
Our analysis reads AVOID: it trades at roughly a 4% discount to our $332.80 fair value, strong competitive moat, 2.60% revenue growth.
Fair value range in USD, drawn from the 2026-10-29 screen. The gold marker is the market price at the same screen. A 3.5% margin of safety to the base estimate.
Third-party analyst targets: 19 covering, consensus Buy. The average target sits +13% from the screen price.
Reading the gap · Both our model and the analysts see meaningful upside from here.

The Business, in Plain Words
Broker giant trips on its own ethics test
Aon sits between big companies and the insurers that actually underwrite their risks, taking a cut on advice and placement without carrying the policies itself. The numbers look tidy, with 46 percent return on equity, 23 percent profit margins and a moat rated strong, yet none of that moves the needle once the ethical screen flags the business activity.
We pass for that single reason. Revenue is growing at just 6 percent and the shares trade above our fair value at 17.2 times forward earnings, so the case was already thin before ethics entered the room. Analyst targets sit higher, but that is not the test we apply.
The main risk is that steady demand for risk advice keeps margins fat even as ethical concerns stay unresolved. Currency moves and any slowdown in corporate spending would still hit results, yet the ethical fail is what keeps us away regardless of the cycle. Analysis, not advice.
The risks · The things to watch: its business and earnings are exposed to Ireland and to currency swings; it carries a real debt load, which raises the stakes if revenue slips.
