Aon profits skyrockets as operating margins hit 34% in record Q1

Aon (NYSE:AON) delivered a robust start to 2026, reporting total revenue of $5.03 billion for the first quarter, a 6% increase compared to the prior-year period.

The results were underpinned by 5% organic revenue growth, reflecting broad-based demand for the firm’s risk management and human capital consulting services.

The company’s focus on operational efficiency and its "Aon United" strategy led to a significant expansion in profitability.

Operating margins rose by 320 basis points to 34.1%, while adjusted operating margins expanded by 100 basis points.

This margin improvement helped drive a 27% increase in GAAP diluted earnings per share to $5.63.

On an adjusted basis, earnings per share reached $6.48, a 14% rise that comfortably exceeded market expectations.

Cash flow generation saw a dramatic recovery during the quarter, with free cash flow surging 332% to $363 million.

This substantial increase was attributed to higher net income and favorable timing of working capital.

Supported by this strong liquidity, Aon returned $662 million to shareholders through share repurchases and dividends.

On April 10, the company underscored its confidence in its long-term trajectory by raising its quarterly dividend by 10%.
