Valuation Multiples

Per-metric breakdown of how AON is priced relative to its sector peers, its own 10-year history, and analyst forward estimates.

Valuation context: This company is valued the way banks and insurers are, on its equity and what it earns on it. Debt is raw material for these businesses, not financing, so the EV multiples are shown for comparison only. The estimates come from P/E, P/B (under Additional valuation multiples), P/S and free cash flow.

What sector peers imply

Value if it traded at the sector-median multiple

What its own history implies

Value if it traded at its own 10-year median multiple

How the Multiples lens works

Five primary multiples surface the headline call; five additional multiples sit one click deeper for context.

Valuation multiples compare a company's market price to its financial fundamentals. The primary grid covers both the equity perspective (P/E, PEG, FCF Yield) and the enterprise value perspective (EV/EBITDA, EV/FCF) so you see how the market prices the company two ways simultaneously.

Price-based multiples use market cap and reflect what equity investors pay. EV-based multiples include debt and are better for comparing companies with different capital structures. The expanded section below adds P/B, P/S, P/FCF, EV/EBIT, and EV/Sales for additional perspective.
