Greenwich, CT, April 21, 2025 - W. R. Berkley Corporation (NYSE: WRB) today reported its first quarter 2025 results.

(1)The 2024 per share amounts were restated for comparative purposes to reflect the 3-for-2 common stock split effected on July 10, 2024.

(2)Operating income is a non-GAAP financial measure defined by the Company as net income excluding after-tax net investment gains (losses) and related expenses.

(3)Return on equity and operating return on equity represent net income and operating income, respectively, expressed on an annualized basis as a percentage of beginning of year common stockholders’ equity.

First quarter highlights included:

•Return on equity and operating return on equity of 19.9% and 19.3%, respectively.

•Record net premiums written grew to $3.1 billion.

•The current accident year combined ratio before catastrophe losses of 3.7 loss ratio points was 87.2%.

•The reported combined ratio was 90.9%, including current accident year catastrophe losses of $111.1 million.

•Average rate increases excluding workers' compensation were approximately 8.3%.

•Net investment income grew 12.6% to $360.3 million.

•Record net invested assets of $30.7 billion.

•Book value per share grew 7.1% in the quarter, before dividends and share repurchases.

The Company commented:

We achieved strong results in the first quarter of 2025 with a 19.9% annualized return on beginning-of-year common stockholders' equity, despite significant first-quarter industry-wide catastrophe losses. These results once again demonstrate our ability to successfully manage underwriting volatility.

Net premiums written grew 10% as market conditions remained favorable in many lines of business, particularly in our Insurance segment. Our 90.9% combined ratio includes 3.7 points of catastrophe losses in a quarter with significant industry catastrophe losses, reflecting our approach to managing volatility as a component of risk-adjusted return.

Net investment income increased significantly compared to the first quarter of 2024, and sequentially from the fourth quarter of 2024, reflecting the impact of higher new money rates on our growing fixed-maturity portfolio and improvement in our investment fund income. The strength of our operating cash flow continues to drive growth in net investable assets, positioning us well for further investment income growth.

Our ability to expand or contract each of our distinct businesses based on specific market conditions remains a significant competitive advantage. This agility enables us to execute our strategy to grow profitably and optimize risk-adjusted returns, while successfully navigating risks and embracing opportunities. We are confident that we will continue to deliver outstanding value to shareholders over the remainder of 2025 and beyond.
