Margins Hold Near 21.5% Net Level

  • Aon reported a trailing net profit margin of 21.5% over the last 12 months, compared with 16.9% in the prior year period.
  • Consensus narrative points to Aon Business Services and tools like Risk Analyzers as key supports for margins, which fits with:
    • Trailing 12 month net income of about US$3.7b on US$17.2b of revenue, consistent with the 21.5% margin cited in the analysis.
    • Analysts expecting profit margins to be around 20.7% in three years, which is slightly lower than today but still close to current levels.

Strong recent margin performance sets a high bar for the bullish view that Aon can keep benefiting from efficiency gains while still funding growth-focused investments in areas like Aon Business Services. 🐂 Aon Bull Case

Earnings Growth Outpaces Revenue

  • Earnings grew 39.2% over the last year, while trailing 12 month revenue growth is cited at 4.3% per year, showing profits rising faster than sales.
  • Analysts' consensus view is that revenue growth will run at about 5.6% a year over the next three years, with earnings expected to reach US$4.2b and EPS of US$19.49 by around April 2029, which sits against:
    • Trailing 12 month earnings of US$3.7b and EPS of US$17.11, so the scenario implies further growth from the current base.
    • Forecast earnings growth of roughly 6.8% a year, which is slower than the 39.2% trailing growth rate highlighted in the recent analysis.

Mixed Valuation Signals Around US$311 Share Price

  • At a share price of US$311.51, Aon is compared with an analyst consensus target of US$389.32 and a DCF fair value of about US$546.96, while trading on a trailing P/E of 18x versus 11.7x for the US Insurance industry and 21.3x for peers.
  • Bears focus on slower forecast growth and leverage, which is weighed against:
    • Revenue forecast to grow 4.3% a year and earnings 6.8% a year, both below the US market forecasts in the same dataset, supporting the concern about slower growth.
    • A high level of debt flagged as a financial position risk, even though the data also notes there has not been substantial insider selling over the past quarter.

The cautious view leans on slower forecast growth and higher debt, while valuation metrics and fair value estimates suggest the pricing story is more complicated than a simple “expensive” label. 🐻 Aon Bear Case
