NYQ · Financial Services · Insurance Brokers
Is Aon plc a safe investment right now?
Aon plc is in the Financial Services sector — Altman Z-Score does not apply to this type of company. Our fair value estimate is $389.95 (Strong Buy Zone).
Why the Altman Z-Score does not apply to Aon plc
The Altman Z-Score is designed for manufacturing and non-financial companies. It uses ratios like Working Capital / Total Assets and Revenue / Total Assets that produce misleading results for Financial Services companies.
- Banks hold massive assets (loans) that inflate Total Assets, making WC/TA nearly zero — a false distress signal
- Utilities carry high regulated debt by design — the model misreads leverage as risk
- REITs use Funds From Operations (FFO), not Free Cash Flow — standard cash flow analysis doesn't apply
Altman Z-Score is designed for manufacturing companies and does not apply to banks, utilities, or REITs.
Note: A sector-specific financial health model for Financial Services companies is planned for a future update.

Why standard moat analysis does not apply to Aon plc
Our standard moat model uses ROIC stability, gross margin trends, and switching costs — metrics designed for product and service companies. Financial Services companies compete on fundamentally different dimensions.
- Banks — moat comes from deposit cost advantage, net interest margin stability, and fee income diversification
- Utilities — moat is a regulatory monopoly with guaranteed rate of return on invested capital
- REITs — moat comes from property portfolio quality, location, tenant mix, and cap rate advantages
Standard moat analysis (ROIC/gross margin/switching costs) does not reliably apply to Financial Services companies. Banks compete on net interest margin, utilities on regulated returns, and REITs on occupancy and cap rates.
Note: A sector-specific competitive analysis for Financial Services companies is planned for a future update.
