Read MoreHide Full Article

Key Takeaways

  • AON's Q4 EPS of $4.85 beat estimates by 1.9% and rose 10% year over year on solid organic growth.
  • Commercial Risk and Reinsurance Solutions drove growth through new business and strong retention rates.
  • 2026 outlook includes EPS growth, margin expansion of 70-80 bps and double-digit free cash flow growth.

Aon plc (AON - Free Report) reported fourth-quarter 2025 adjusted earnings of $4.85 per share, which surpassed the Zacks Consensus Estimate by 1.9%. The bottom line advanced 10% year over year. 

Total revenues of $4.3 billion grew 4% year over year. However, the top line fell short of the consensus mark by 1.7%. Organic revenue growth was 5%.

The quarterly results gained from solid organic revenue growth, robust new business and high retention across key solution lines like Commercial Risk and Reinsurance Solutions. Growth in insurance-linked securities and advisory demand in Retirement services also contributed, along with net restructuring savings that supported a margin expansion. However, the upside was partially offset by increased operating expenses linked to the Accelerating Aon United Program and unfavorable foreign currency translation.
