AM Best has revised the outlooks to positive from stable for the Long-Term Issuer Credit Ratings (Long-Term ICRs) of several RenaissanceRe entities, including Renaissance Reinsurance Ltd., Renaissance Reinsurance US Inc., RenaissanceRe Specialty US Ltd., Renaissance Reinsurance of Europe Designated Activity Company, and RenaissanceRe Europe AG.

The Financial Strength Rating (FSR) of A+ (Superior) and the Long-Term ICRs of “aa-” (Superior) for these companies have been affirmed. The outlook for the FSR remains stable.

AM Best’s ratings for RenaissanceRe reflect what the agency describes as the group’s strongest balance sheet strength, adequate operating performance, a very favorable business profile, and very strong enterprise risk management.

The revision of the Long-Term ICR outlook to positive for RenaissanceRe is attributed to improved operating performance in recent years, with reduced volatility as specialty and casualty lines have become a larger part of the portfolio. These lines have partially offset the volatility from the property catastrophe core of RenaissanceRe’s business.

RenaissanceRe remains exposed to high-severity losses from global catastrophe events, but diversification into other business lines has helped mitigate the impact of these losses. Growth in casualty lines introduces potential reserve volatility, though the company has reinsurance protection in place to absorb some adverse development on legacy reserves if needed.

RenaissanceRe’s financial results for the first quarter of 2025 reflected the impact of catastrophe-related losses. The company reported net income attributable to common shareholders of US$161.1 million, down from US$364.8 million in the same quarter last year. The quarter included a US$702.8 million after-tax loss, primarily linked to California wildfires, which contributed to a combined ratio of 128.3, compared to 77.9 in the prior-year period.

AM Best’s assessment of RenaissanceRe’s balance sheet strength takes into account the financial flexibility of its parent, RNR, which maintains significant capital at the holding company level.

The company’s business profile is supported by a strong global position in property catastrophe reinsurance and expanding casualty and specialty lines, which now make up more than half of underwriting premiums.

In June, RenaissanceRe announced several leadership promotions across its US operations and global underwriting teams. RJ Shea was named president of Renaissance Reinsurance US Inc., taking responsibility for underwriting operations and client relationships in the US market.

Adriana Nivia was promoted to managing director for North America, overseeing operational functions in the region, while Jim Riley became global head of casualty, and Mehdi Benleulmi was appointed global head of credit.
