IAG shares dip on Queensland news
On 1 September 2025, IAG reported it had completed its acquisition of the Royal Automobile Club of Queensland (RACQ) for the tidy sum of $855 million, with IAG owning 90% of RACQ shares.
"Today is an exciting day as we begin our partnership with RACQ, supporting its member-first approach, welcoming around 840 new team members to IAG, and strengthening our commitment to Queensland," IAG CEO Nick Hawkins said at the time.
IAG shares closed up 0.6% on the day.
Today, the ASX 200 insurance company announced the successful integration of RACQ Insurance (RACQI) into its main catastrophe cover, whole of account quota share (WAQS) arrangements, and aggregate stop-loss protection.
IAG also revealed that it has expanded its WAQS arrangements to now cover 35% of the consolidated business. Management reiterated that they have maintained RACQI's separate standalone reinsurance program that comprised quota share and catastrophe protections.
Cutting to the chase, IAG shares could gain longer-term support with its RACQI branch now also covered by the catastrophe reinsurance program for the 2026 calendar year.
IAG's total 2026 catastrophe reinsurance program provides a main catastrophe cover for two events up to $10 billion, with an attachment at $500 million.
The company noted that RACQI's quota shares have now been replaced by IAG's WAQS arrangements, adding that the total proportion ceded has increased by 2.5% to now represent 35% of IAG's combined business.
What did management say?
Commenting on the reinsurance program integration that has yet to lift IAG shares today, chief financial officer William McDonnell said, "We are pleased to have integrated the RACQI business into the overall reinsurance program which will achieve the targeted synergies."
McDonnell added:
Global reinsurance markets have improved during 2025, allowing us to renew reinsurance protection favourably relative to expectations. In addition, IAG received strong support from reinsurance partners in expanding the overall program, resulting in a further reduction in the volatility of our earnings.
How have IAG shares been tracking?
With today's intraday dip factored in, IAG shares are down 8.5% over the past 12 months.
The ASX 200 insurance stock also trades on a 3.9% partly franked trailing dividend yield.
IAG is scheduled to announce its half-year results for the six months to 31 December on 12 February.
