Insurance Brands and Main Operating Activities

IAG (ASX:IAG) operates insurance businesses serving households, motorists, businesses and rural customers. Brands in its Australian operations include NRMA Insurance, CGU and WFI, alongside New Zealand brands such as AMI and NZI. The group collects premiums, pays eligible claims, manages operating expenses and invests funds held to meet insurance obligations.

Gross written premium measures policy premiums written rather than final earnings. Underwriting profitability depends on claim frequency and severity, reinsurance protection, repair and building costs, and the difference between premium income earned and the cost of coverage delivered. Investment income is another part of overall financial performance.

FY26 Premium Growth and Insurance Result

For the year ended 30 June 2026, IAG (ASX:IAG) reported gross written premium of AUD 18.412 billion, compared with AUD 17.106 billion in FY25. Australian retail premium rose to AUD 10.308 billion; the acquired RACQI operations contributed approximately AUD 1.272 billion to the year’s total.

Net profit after tax was AUD 1.022 billion, compared with AUD 1.359 billion in FY25. Reported pre-tax insurance profit was AUD 1.552 billion, compared with AUD 1.743 billion. Comparisons require care because prior-period outcomes included releases and favourable peril experience that did not repeat in the same way.

Weather Exposure and Claims Experience

The insurer reported FY26 natural peril costs AUD 114 million above its allowance, compared with favourable experience in FY25. This contributed to differences between reported and underlying outcomes. Underlying insurance profit reached AUD 1.578 billion, compared with AUD 1.542 billion in the previous year.

IAG (ASX:IAG) uses reinsurance to manage exposure to significant events, although policy terms, attachment levels and the timing of weather incidents still affect the amount retained. Claims Inflation from labour and repairs can also affect settlement costs, even when the number of insured incidents is unchanged.

Integration, Risks and Monitoring Points

The RACQI contribution is material when interpreting the movement in premiums. Integration introduces operational work involving systems, servicing, risk selection and consistency across insurance products. It should not be assumed that additional gross premiums produce an equivalent percentage rise in profit, particularly when claims and acquisition-related costs change.

IAG (ASX:IAG) faces natural disasters, inflation in claims settlement, regulatory requirements, competition, reserve uncertainty and movements in investment markets. Future disclosures can clarify insurance margins, premium growth excluding acquisitions, realised weather costs, Capital management and the progress of integrations.
