Suncorp has locked in up to A$2.4 billion ($1.71 billion) of reinsurance protection over five years and lifted its fiscal 2026 growth outlook, sending shares in the Australian general insurer to their highest level in nearly five months.
The stock jumped as much as 10.2% to A$17.98 in early Friday trade, its strongest level since Nov. 28. A close at that level would mark the biggest single-day gain since Aug. 21, 2020.
Suncorp expects gross written premium to grow 3% in fiscal 2026 across its Australia and New Zealand businesses, supported by the new cover.
The deal is a five-year aggregate arrangement worth A$800 million a year, effective June 30. It attaches at A$1.85 billion in fiscal 2027, A$50 million above the insurer's natural hazard allowance, and is indexed to exposure growth.
Suncorp says the structure should cap natural hazard costs in roughly 90% of scenarios. It replaces existing dropdown protections below A$350 million, streamlining the group's reinsurance program. Suncorp's main catastrophe cover for fiscal 2027 has yet to be placed and is expected to be finalized by June 30, 2026.
The insurer expects a one-off capital release of about A$100 million, reflecting a modest cut to its capital target. Under APRA's LAGIC framework, Australian general insurers must hold capital against a one-in-200-year loss on a whole-portfolio basis, with reinsurance recognized up to that threshold.
Acting chief executive Jeremy Robson said the margin outlook was "unchanged at the upper end of our target range but with significantly improved resilience and reduced volatility in earnings."
He added that fiscal 2026 natural hazard costs are tracking about A$250 million above allowance, assuming no further major weather events.
Suncorp's underlying insurance trading ratio guidance for the year stays at the top of the 10% to 12% range.
The move mirrors a deal struck in mid-2024 by rival IAG, which secured up to A$680 million a year and A$2.8 billion over five years from Berkshire Hathaway's National Indemnity and Canada Life Re. IAG flagged an expected capital benefit of around A$350 million from that arrangement.
Suncorp's placement lands in a visibly softer reinsurance market. Gallagher Re's January 2026 1st View report said record capital and subdued demand at the Jan. 1 renewals handed leverage to cedants, opening the door to price cuts and more flexible structures.
Risk-adjusted pricing on non-loss-impacted catastrophe programs in major markets fell 10% to 20% at the renewal, while insurance-linked securities issuance topped $20 billion in 2025.
Gallagher Re global chief executive Tom Wakefield said "the 1.1.26 renewal represented further price reduction and structural flexibility."
