Suncorp Group Ltd's stock surged 7.57% during intraday trading on Friday, following the announcement of a significant reinsurance agreement and updated financial guidance.

The Australian general insurer secured a five-year aggregate reinsurance cover providing up to A$2.4 billion in total protection, with A$800 million of annual coverage. This arrangement is expected to reduce overall volatility in net claims costs and drive a one-off capital release of approximately A$100 million through a modest reduction in the capital target.

Additionally, the company maintained its underlying insurance trading ratio outlook for fiscal 2026 at the upper end of its 10%-12% target range and now expects gross written premium growth of about 3% for the period. Acting CEO Jeremy Robson stated that the underlying margin outlook remains unchanged but with "significantly improved resilience and reduced volatility in earnings."
