Rhea AI AON FY2025 2026-08-29

Aon’s dominant business mechanic is cash-generative growth paired with balance-sheet repair, while FY2025 profit expanded faster than operating cash flow.

The key earnings-quality shift is that reported profitability improved faster than cash conversion: net margin moved from 16.9% to 21.5%. Operating cash flow remained below net income at $3.5B versus $3.7B, so the income statement was stronger than the cash generated in the latest year.

The capital structure changed direction: equity moved from -$826M in FY2023 to $9.4B in FY2025, turning a negative-equity balance sheet positive. The shift created positive equity while total liabilities fell to $41.2B even as assets rose to $50.8B, indicating the larger asset base was not accompanied by proportional liability growth.

Operating margin rose from 24.4% to 25.3% in FY2025, showing that additional scale was not fully absorbed by overhead and suggesting improved operating leverage. Meanwhile, capital intensity stayed restrained: free cash flow was $3.2B against capital expenditures of $263M, indicating the model does not require heavy physical reinvestment to produce cash.
