What did Insurance Australia Group report?
- Proposed acquisition of RAC Insurance enters Phase 2 review by the ACCC.
- ACCC says the deal could substantially lessen competition in WA's insurance market.
- No conclusion reached yet – review continues under the new formal merger regime.
- Submissions on the Phase 2 Notice are invited until 4 May 2026.
What else do investors need to know?
The ACCC's review focuses on the competitive impacts across both the motor vehicle and home and contents insurance markets in Western Australia. The regulator is also examining implications for related services like smash repairs, given the market share of both companies in the region.
IAG previously reapplied for approval under the new merger regime that started in January 2026, after the ACCC didn't clear the deal under the old informal process last year. The current review will take up to 90 business days unless extended, allowing the ACCC to explore competition impacts in detail.
What's next for Insurance Australia Group?
Investors can expect more updates as the ACCC's Phase 2 review progresses. The outcome will determine whether IAG can proceed with bringing RACI into its portfolio and underwriting its home and motor insurance products under the RAC brand.
For now, IAG continues to operate its existing brands across Australia and New Zealand, including partnerships and underwriting for third parties. The company's growth strategy depends partly on the outcome of this high-profile merger review.
