Aon's initial 2026 margin guidance is slightly better than analyst estimates, on the heels of a solid fourth quarter. Bloomberg Intelligence notes that organic growth was in line with Wall Street as upside in reinsurance offset a miss in health. The 2025 result of 6% is close to the previous three years but better than peer Marsh. The consolidated adjusted operating margin beat consensus and expanded from a year earlier making the 2025 result also better than estimates.

Edmund Reese, Executive Vice President and Chief Financial Officer of Aon, discusses the key risks facing the firm in 2026 and how it is positioning itself to better serve clients and stakeholders amid global uncertainty. Edmund speaks with Carol Massar and Tim Stenovec on Bloomberg Businessweek Daily.
