Aon PLC Financial Ratios 2025-2006 | AON

Brief overview of Aon PLC's valuation multiples

The review covers five available annual periods spanning 2021 to 2025.

Market valuation is represented by P/E 18.7x (median 25.4x), P/B 7.24x (median 14.59x), P/CF 19.85x (median 20.43x). Valuation is roughly 26.4% below five-year reference levels. The discount may reflect opportunity or higher perceived risk.

The 1/P/E calculation produces a 5.3% earnings yield. It does not capture future growth or capital structure.

Current measures of operating quality are ROE 39.5%, ROA 7.3%, ROCE 46.4%. Profitability forms a strong profile, with capital and assets producing substantial returns.

The PEG ratio is 1.26x, reflecting a relatively balanced link between valuation and growth.

For this sector, valuation ratios are useful only alongside capital adequacy, reserves and credit-portfolio quality.

Overall assessment

Aon PLC combines strong fundamental efficiency with valuation below its own five-year norm. The discount merits attention but should be checked against sector and financial risks.

Multiples are an important financial analysis tool for the company Aon PLC, allowing investors and analysts to quickly assess the company’s value and investment attractiveness based on the ratio of market indicators to the company’s financial performance. Essentially, multiples express how the market values the company relative to its earnings, revenue, equity, or other key metrics.

Advantages of Using Financial Ratios
  • Simplified Data Analysis
    Financial ratios transform large volumes of accounting data into compact and easily interpretable indicators, significantly simplifying the assessment of the company’s condition.
  • Comparability Between Companies
    Multiples standardize financial metrics, enabling objective comparison of companies of different sizes, industries, and market capitalizations.
  • Identification of Trends and Issues
    Regular analysis of ratios helps track the dynamics of financial health, identify strengths and weaknesses of the business, as well as potential risks.
  • Decision Support
    Financial multiples serve as an important tool for investors, creditors, and company management in making investment, credit, and managerial decisions.
  • Accelerated Assessment of Investment Attractiveness
    Ratios allow quick determination of key performance, liquidity, and financial stability indicators, facilitating prompt evaluation of companies’ attractiveness for investments.

Using multiples enables comparison between companies, even if they differ in size or industry, as they standardize financial data into ratios convenient for analysis. This is especially useful for evaluating companies where direct analysis of financial statements may be complex or require in-depth knowledge.
