The Insurance Australia Group Ltd (ASX: IAG) share price is in focus today after the ACCC blocked its planned acquisition of RAC Insurance, citing concerns over reduced competition in Western Australia's car and home insurance markets.

What did Insurance Australia Group report?
- The ACCC has formally opposed IAG's proposed acquisition of RAC Insurance (RACI).
- The decision follows an in-depth Phase 2 review under the new formal merger regime.
- If approved, IAG's WA market share would have climbed to 55–65% in motor insurance and 50–60% in home and contents.
- IAG currently supplies insurance products nationally under brands like NRMA, CGU and WFI.
- The determination does not impact IAG's other business activities or previous acquisitions.
What else do investors need to know?
The ACCC found that combining IAG with RACI would substantially lessen competition for both motor vehicle and home insurance in Western Australia. The regulator noted that other insurers wouldn't provide enough competitive pressure to offset this.
The proposed deal was first opposed by the ACCC in December 2025, under the informal regime. IAG resubmitted for approval under the formal merger rules that started in January 2026. The process included detailed consultation and analysis of submissions from industry stakeholders.
If the parties wish to challenge this determination, they may lodge a public benefit application for further review, which allows a separate consideration of the potential benefits versus the public detriment.
What's next for Insurance Australia Group?
IAG is now expected to maintain its existing brands and strategies in Western Australia without the RAC Insurance acquisition. The group still has a strong presence through brands like NRMA and CGU, and previously announced growth plans, including digital innovation and customer experience enhancements.
Any further action on the acquisition will depend on whether IAG decides to pursue a public benefit application with the ACCC. Otherwise, IAG's focus is likely to remain on organic growth in existing markets and delivering value for shareholders.
