Aon stock gets 35% ACT capacity for 2027

Aon announced on Wednesday, November 4, that it had renewed the Aon Client Treaty for 2027 and would expand the facility's eligible co-insurance share from 28.5 percent to 35 percent from January 1. The company said the arrangement is intended to give clients access to committed capacity for selected insurance and reinsurance risks.

According to PR Newswire, the renewed facility will cover eligible business placed through Aon's Global Broking Centre and facultative reinsurance placed by Aon's Reinsurance Solutions. QBE leads the facility, which is backed by Lloyd's syndicates.

Broader access to committed capacity

Aon said the 1.5 percent ACT Client Dividend would apply to the larger 35 percent share where local law, regulation and eligibility conditions permit. Clients using the facility receive capacity on the same terms and pricing as the lead placement, subject to client agreement and Aon's conflicts of interest framework.

The expansion is particularly relevant to facultative reinsurance, which supports large or complex individual risks that may not fit standard treaty programs. Aon said ACT has supported this business since late 2025. The arrangement therefore gives the brokerage a broader role in organizing capacity for placements beginning in 2027, although the benefit depends on eligible business and client participation.

Aon stock traded at 298.65 euros on Lang & Schwarz at 10:48 CET on Wednesday, November 11, 2026.

The broader insurance market remains relevant for Aon's ability to place complex risks and connect clients with underwriting capacity. See the current S&P 500 market environment.
