78

Aon Plc has an operating margin of 25.3%, meaning the company retains $25 of operating profit per $100 of revenue. This strong profitability earns a score of 78/100, reflecting efficient cost management and pricing power. This is up from 24.4% the prior year.

Growth
49

Aon Plc's revenue grew 9.4% year-over-year to $17.2B, a solid pace of expansion. This earns a growth score of 49/100.

Leverage
70

Aon Plc carries a low D/E ratio of 1.57, meaning only $1.57 of long-term debt for every $1 of shareholders' equity. This conservative leverage earns a score of 70/100, indicating a strong balance sheet with room for future borrowing.

Liquidity
17

Aon Plc's current ratio of 1.11 means current assets barely cover short-term liabilities. This tight liquidity results in a low score of 17/100, which could limit financial flexibility.

Returns
99

Aon Plc earns a strong 39.5% return on equity (ROE), meaning it generates $40 of profit for every $100 of shareholders' equity. This efficient capital use earns a returns score of 99/100. This is down from 43.4% the prior year.

Altman Z-Score Distress
1.68

Aon Plc scores 1.68, below the 1.81 distress threshold. The score is driven primarily by a large market capitalization ($69.4B) relative to total liabilities ($41.2B). This indicates elevated financial distress risk and warrants close attention to liquidity and debt levels.

7/9

Aon Plc passes 7 of 9 financial strength tests. 3 of 4 profitability signals pass, all 3 leverage/liquidity signals pass, both operating efficiency signals pass.

Earnings Quality Mixed
0.94x
