Aon increases co-insurance capacity to 35% for 2027, boosting client risk coverage and dividends.

Aon plc announced it will raise the co-insurance share under its Aon Client Treaty (ACT) to 35% from 28.5% starting January 2027. This expansion applies to eligible business placed through Aon's Global Broking Centre and facultative reinsurance via Aon's Reinsurance Solutions, allowing clients greater access to committed risk capital and a 1.5% client dividend on the larger share. The move responds to growing client demand for efficient risk placement and supports complex insurance needs with strong backing from market partners like QBE and Lloyd's syndicates. Since 2016, ACT has placed over $5 billion in premiums, and this increase aims to enhance client confidence and streamline risk management.

Aon PLC shares are trading at USD 329.39 on Pluang as of November 4, 2026, slightly below their 52-week high of USD 381.26 but well above the 52-week low of USD 269.45. Despite a modest 0.23% decline on the day, the stock maintains a dividend yield of 0.98%, contrasting with a majority 63% sell order activity versus 37% buy. This pricing context highlights investor caution even as Aon expands its co-insurance share under the Aon Client Treaty for 2027.
