RenRe Releases $178M of Cat Reserves as Specialty Runs 110.6%

RenaissanceRe released $178.2 million of prior-year reserves from its property catastrophe class in the third quarter, mostly from the 2021, 2022 and 2024 loss years, and a further $86.9 million from other property, the company said in its October 27 earnings release. The releases took the Property segment to a 32.4% combined ratio while Casualty and Specialty ran at 110.6%.

The group combined ratio was 79.7%, against 68.4% a year earlier. Three named 2026 events, the Middle East war, the Ras Laffan explosion in Qatar and the Colombian earthquake, cost $191.4 million of underwriting result and 9.3 points of the ratio. Mark-to-market losses of $879.8 million on the investment portfolio left a net loss of $161.4 million to common shareholders against operating income of $512.6 million.

The result comes in the fortnight after Everest added about $600 million gross to its casualty reinsurance reserves. Chubb reported $13 million of adverse long-tail development inside a $511 million release in the same stretch. RenaissanceRe's casualty book barely moved in the quarter. Its loss sat in specialty.

Key Takeaways

Property released $265.0 million of prior-year reserves, 32.0 points of its ratio, with $178.2 million from the catastrophe class on the 2021, 2022 and 2024 events.
Casualty and Specialty lost $134.5 million on underwriting as the war, the Ras Laffan explosion and the earthquake added 10.5 points to its combined ratio.
Property gross premiums written fell 14.3% to $628.8 million on rate reductions in both classes, so each dollar of release now moves the ratio further.
Casualty prior-year development was 0.2 points favorable in the quarter, and the nine-month adverse figure of $54.7 million is almost all the second-quarter Baltimore Bridge shift.
Fee income fell to $81.7 million from $101.8 million because DaVinci carried higher current-year losses and Fontana booked an underwriting loss.

Two books, one ratio

Property earned $560.6 million of underwriting income on $829.8 million of net premiums earned, down from $791.5 million a year earlier, when the segment ran at 15.5%. Casualty and Specialty lost $134.5 million against a $21.3 million loss in the third quarter of 2025, and its combined ratio rose 9.2 points from 101.4%.

The release puts the three 2026 events at $191.4 million net of recoveries and reinstatement premiums. After tax and the joint-venture investors' share, they cost $111.5 million of net income available to common shareholders. Reinsurance News put the split at $133.3 million in Casualty and Specialty and $58.2 million in Property.

Middle East war: $69.7 million, 5.5 points of the Casualty and Specialty ratio and none of Property's.
Ras Laffan explosion: $65.2 million, 4.7 points on Casualty and Specialty and 0.9 on Property.
Colombian earthquake: $56.6 million, 6.3 points on Property and 0.3 on Casualty and Specialty.

David Marra, Group Chief Underwriting Officer, described the second event on the October 28 call as "an explosion from an operational accident at the Ras Laffan gas complex in Qatar." RenaissanceRe has reserved "our share of a full limit loss of $1.7 billion," he said. The lines that need rate after the quarter are "marine and energy, as well as political violence and aviation," he said. None of them is a casualty class.

The release against a shrinking premium base

The catastrophe-class release has grown each quarter this year while the premium beneath it has shrunk. The first-quarter release cited the 2021, 2022 and 2023 events, the second added 2024 and 2025, and the third named 2021, 2022 and 2024.

Quarter	Catastrophe class release	Loss years cited	Other property release	Property combined ratio
Q1 2026	$62.6M	2021, 2022, 2023	$98.1M	34.1%
Q2 2026	$132.7M	2021, 2022, 2024, 2025	$124.7M	27.1%
Q3 2026	$178.2M	2021, 2022, 2024	$86.9M	32.4%
Nine months	$373.5M		$309.7M	31.2%

Sources: RenaissanceRe Q1, Q2 and Q3 2026 earnings releases. The nine-month Property release totals $683.2 million, 26.1 points of the segment ratio.

Gross premiums written in Property fell $104.5 million, or 14.3%, to $628.8 million, "driven by rate reductions across both the catastrophe and other property classes," the release said. The catastrophe class wrote $231.1 million against $288.4 million a year earlier and other property $397.7 million against $444.9 million. Net premiums earned fell 11.4% to $829.8 million.

That earned base is what the release is measured against. On $829.8 million, the $265.0 million release was worth 32.0 points. On a base 14.3% smaller, the same dollars would be worth about 37 points. Each dollar of release that does not arrive costs the ratio more than it did this quarter. The release does not say how much margin remains in the 2021, 2022 and 2024 years.

The casualty book barely moved

Casualty and Specialty's prior accident years developed 0.2 points favorably in the quarter. That figure "included an adverse impact of 0.4 percentage points related to purchase accounting adjustments," the release said. Chief Financial Officer Robert Qutub said there was "nothing like that in the third quarter" when asked about a repeat of the second quarter's casualty assumption change.

For the nine months the segment shows $54.7 million of adverse development, 1.4 points. Almost all of it is the second quarter's $54.0 million shift of Baltimore Bridge loss estimates out of Property, covered in the second-quarter piece, plus the purchase accounting charge. The first and third quarters were each slightly favorable. The reserve for claims and claim expenses stood at $22.3 billion at September 30, unchanged from December 31.

Segment gross premiums written fell 7.2% to $1,475.3 million, "principally due to exposure reductions across the general casualty and professional liability classes," the release said. Net premiums written fell 20.5% to $1,084.5 million as the segment ceded a larger share, continuing the retro build reported in July.

The peer contrast shows in the reserve lines. Everest's roughly $600 million gross casualty strengthening, $253 million net in Reinsurance Treaty, pushed that segment to a 108.5% combined ratio and the group to 107.1%, Everest said on October 28. The same Colombia earthquake and Middle East events cost Everest $277 million in the treaty segment (the Everest charge). Chubb's $511 million of favorable development carried "$13 million of unfavorable development in long tail lines," Chief Financial Officer Peter Enns said on October 21. The company attributed the long-tail figure to general casualty (the Chubb split).

RenaissanceRe reported a worse ratio than either in the segment that holds its casualty book and strengthened nothing there. Its 10.5 points of loss came from war, energy and earthquake exposures written in the specialty classes.

What reached the joint ventures

Fee income fell to $81.7 million from $101.8 million. Management fees dropped to $48.4 million from $53.0 million on lower net premiums earned in DaVinci and Fontana. Performance fees fell to $33.3 million from $48.8 million, "primarily driven by higher current accident year net losses in DaVinci," the release said. Net income attributable to redeemable noncontrolling interests, the third-party investors' share of the vehicles' results, was $150.7 million against $415.2 million. DaVinci and Vermeer drove it, "partly offset by an underwriting loss in Fontana," the release said.

Fontana is the casualty and specialty vehicle RenaissanceRe started in 2022, so the specialty losses reached third-party capital in the same quarter the property releases did. RenaissanceRe still returned $61.6 million of excess capital to Fontana's investors from retained earnings. That was part of $249.3 million returned in the quarter, alongside $171.2 million of released collateral from Upsilon Diversified. It raised $152.6 million, of which $150.0 million came through the Lighthouse Cat Bond Fund, a separately managed account of Upsilon that invests in catastrophe bonds.

The segment lines therefore show more release, and more specialty loss, than RenaissanceRe's own shareholders received. Both were shared with the vehicles in proportion to their participation.

The next test of the property base is the January 1 renewal. Property catastrophe rates are down "mid teens" so far this year and "we expect rates will be down less than in 2026," Marra said. Cat bond competition at the top of programs "could be more than what we saw this year," he said. Demand growth would be positive "but not as much as what we have seen in previous years," in the single-digit billions against the $20 billion of a few years ago.
