PEORIA, ILLINOIS, January 21, 2026 – RLI Corp. (NYSE: RLI) – RLI Corp. reported fourth quarter 2025 net earnings of $91.2 million ($0.99 per share), compared to $40.9 million ($0.44 per share) for the fourth quarter of 2024.

	Fourth Quarter				Year to Date
Earnings Per Diluted Share	2025		2024		2025		2024
Net earnings	$	0.99	$	0.44	$	4.37	$	3.74

See discussion below: Non-GAAP and Performance Measures.

(2)

Equity in earnings of unconsolidated investees and the related taxes were removed from operating earnings and operating earnings per share, resulting in consistent exclusion of unrealized changes in equity investments from operating results. Prior period amounts have been recast to conform to the current definition.

Highlights for the quarter included:

●

Underwriting income⁽¹⁾ of $70.9 million on a combined ratio⁽¹⁾ of 82.6.

●

Net investment income increased 9%, while gross premiums written declined 2%.

●

Favorable development in prior years’ loss reserves resulted in a $22.0 million net increase in underwriting income.

●

Special dividend of $2.00 per share, representing $183.7 million returned to shareholders.

Highlights for the year included:

●

Underwriting income⁽¹⁾ of $264.2 million on a combined ratio⁽¹⁾ of 83.6.

●

2025 delivered our 30th consecutive year of underwriting income.

●

12% increase in net investment income and 1% increase in gross premiums written.

●

Favorable development in prior years’ loss reserves resulted in an $87.4 million net increase in underwriting income.

●

Book value per share of $19.35, an increase of 33% (inclusive of dividends) from year-end 2024.

“Our fourth-quarter results reflect the strength of our diversified specialty product portfolio and underwriting discipline,” said RLI Corp. President & CEO Craig Kliethermes. “We achieved an 83 combined ratio, underscoring our ability to produce positive underwriting results in a highly competitive market while remaining focused on profitability.”

“For the full year, premium growth was modest at 1%, but our strong underwriting performance drove an 84 combined ratio, marking our 30th consecutive year of underwriting profitability. Favorable underwriting and investment outcomes contributed to a 33% increase in book value from year-end 2024 and supported meaningful returns to shareholders. These results highlight the discipline, expertise and ownership mindset of our associate-owners, which continue to make RLI different.”

Underwriting Income

RLI achieved $70.9 million of underwriting income in the fourth quarter of 2025 on an 82.6 combined ratio, compared to $22.2 million on a 94.4 combined ratio in 2024.

For the year, RLI achieved $264.2 million of underwriting income on an 83.6 combined ratio, compared to $210.7 million on an 86.2 combined ratio in 2024. Results for both years include favorable development in prior years’ loss reserves, which resulted in an $87.4 million and $84.1 million net increase to underwriting income in 2025 and 2024, respectively. The favorable development was offset by a $26.5 million net reduction to underwriting income for storm losses in 2025. This compares to $93.6 million for losses from Hurricanes Beryl, Helene and Milton, as well as other storm losses, in 2024.

The following table highlights underwriting income and combined ratios by segment for the year.

Other Income

Net investment income for the quarter increased 9% to $42.3 million, compared to the same period in 2024. For the year ended December 31, 2025, net investment income was $159.7 million, compared to $142.3 million for the same period in 2024. The investment portfolio’s total return was 1.5% for the quarter and 9.0% for the year.

RLI’s comprehensive earnings were $100.4 million for the quarter ($1.09 per share), compared to a comprehensive loss of $26.3 million (-$0.28 per share) for the same quarter in 2024. In addition to net earnings, comprehensive earnings for 2025 included after-tax unrealized gains from the fixed income portfolio, due to declining interest rates. Full-year comprehensive earnings were $489.0 million ($5.29 per share), compared to $338.4 million ($3.66 per share) in 2024.

Special and Regular Dividends

On December 19, 2025, the company paid a special cash dividend of $2.00 per share and a regular quarterly dividend of $0.16 per share for a combined total of $198.4 million. RLI has paid dividends for 198 consecutive quarters and increased regular dividends in each of the last 50 years. Over the last 10 years, the company has returned more than $1.6 billion to shareholders and the regular divided has grown an average of 5.4% per year.

Non-GAAP and Performance Measures

Management has included certain non-generally accepted accounting principles (non-GAAP) financial measures in presenting the company’s results. Management believes that these non-GAAP measures further explain the company’s results of operations and allow for a more complete understanding of the underlying trends in the company’s business. These measures should not be viewed as a substitute for those determined in accordance with generally accepted accounting principles (GAAP). In addition, our definitions of these items may not be comparable to the definitions used by other companies.

Operating earnings and operating earnings per share (EPS) consist of our GAAP net earnings adjusted by net realized gains/(losses), net unrealized gains/(losses) on equity securities and taxes related thereto. Beginning in the fourth quarter of 2025, equity in earnings of unconsolidated investees and the related taxes were excluded from operating earnings and operating EPS. The change was made to present a consistent approach in excluding all unrealized changes in equity investments. We view these minority investments as outside of RLI’s operating control. Operating earnings and operating EPS for prior periods have been recast to conform to the current definition. Net earnings and net earnings per share are the GAAP financial measures that are most directly comparable to operating earnings and operating EPS. A reconciliation of the operating earnings and operating EPS to the comparable GAAP financial measures is included in the 2025 financial highlights below.

Underwriting income or profit represents the pretax profitability of our insurance operations and is derived by subtracting loss and settlement expenses, policy acquisition costs and insurance operating expenses from net premium earned, which are all GAAP financial measures. The combined ratio, which is derived from components of underwriting income, is a performance measure commonly used by property and casualty insurance companies and is calculated as the sum of loss and settlement expenses, policy acquisition costs and insurance operating expenses, divided by net premiums earned, which are all GAAP measures.
