Financial Snapshot

Revenue & Earnings Trends

Aon reported Q4 FY25 revenue of $4.3 billion and operating earnings near $1.05 billion in that quarter, showing resilience in fee-based revenue and client retention. Over the trailing 12 months EPS stands at $17.03, supporting a trailing P/E near 18.2. Revenue growth has been supported by advisory and reinsurance placement activity, while higher-margin services have helped lift operating leverage.

Balance Sheet Highlights

The company maintains a current ratio of 1.11, reflecting adequate short-term liquidity for operations. Price to book is elevated at 8.11, which reflects the intangible-heavy nature of the business and strong return on equity. Available data indicates enterprise value near the low-80s billion range, suggesting a leveraged but manageable capital structure for a firm with consistent cash generation.

Valuation Analysis

Historical Comparison

Current multiples put Aon at or slightly below recent peak valuations, while above multi-year lows. Trailing P/E near 18 is inside the range the market has given high-quality brokers in recent years. Given Aon's superior ROE and recurring fee streams, its premium to lower-margin competitors has generally been maintained over the past five years.

Fair Value Estimate

Using a multiples-based approach and taking analyst forward EPS consensus into account, fair value sits in a range roughly between $360 and $420 per share. The mean analyst target near $397 implies about 23% upside from $322.81. Valuation tailwinds include margin expansion from tech and payments, while downside is limited by a high base of goodwill and elevated price to book.
