(2) Equity in earnings of unconsolidated investees and the related taxes were removed from operating earnings and operating earnings per share beginning in the fourth quarter of 2025, 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 $59.9 million on a combined ratio(1) of 85.6.

● Net investment income increased 17%, and gross premiums written increased 3%.

● Favorable development in prior years’ loss reserves resulted in a $35.1 million net increase in underwriting income.

● Book value per share of $19.09, an increase of 11% (inclusive of dividends and share repurchases) from year-end 2025.

● Authorized a $250.0 million share repurchase program and repurchased $12.0 million of common stock.

● Paid a special dividend of $2.00 per share, returning $184.0 million to shareholders.

“We are pleased to report another quarter of premium growth and profitability,” said RLI Corp. President & CEO Craig Kliethermes. “Gross premiums written increased 3%, driven by our casualty segment, while strong margins in our property and surety segments contributed to an 86 combined ratio. Net investment income increased 17%, complementing our underwriting results and contributing to an 11% increase in book value per share since year-end 2025, including dividends returned to shareholders. These results reflect our disciplined execution and continued focus on delivering specialized expertise and exceptional service to our customers.”

Underwriting Income

RLI achieved $59.9 million of underwriting income in the second quarter of 2026 on an 85.6 combined ratio, compared to $62.2 million on an 84.5 combined ratio in 2025.

Results for both years include favorable development in prior years’ loss reserves, which resulted in a $35.1 million and $24.4 million net increase to underwriting income in 2026 and 2025, respectively.

Other Income

Net investment income for the quarter increased 17% to $46.0 million, compared to the same period in 2025. The investment portfolio’s total return was 3.4% for the quarter and 3.0% for the six months ended June 30, 2026.

RLI’s comprehensive earnings were $165.7 million for the quarter ($1.80 per share), compared to $143.0 million ($1.55 per share) for the same quarter in 2025. In addition to net earnings, comprehensive earnings for 2026 included after-tax unrealized losses from the fixed income portfolio, due to rising interest rates.

Dividends and Share Repurchase Program

On June 12, 2026, the company paid a special cash dividend of $2.00 per share and a regular quarterly dividend of $0.18 per share, a 12.5% increase over the prior quarter.

On May 14, 2026, the company’s Board of Directors authorized a share repurchase program of up to $250.0 million of the company’s outstanding common stock. During the second quarter, RLI repurchased 234,973 shares at an average price of $51.25 per share for a total cost of $12.0 million. As of June 30, 2026, $238.0 million of remaining capacity was available under the share repurchase program. Over the past five years, RLI has returned more than $1.3 billion to its shareholders through dividends and share repurchases.

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. Equity in earnings of unconsolidated investees and the related taxes were excluded from operating earnings and operating EPS beginning in the fourth quarter of 2025. The change was made to present a consistent approach in excluding all unrealized changes in equity investments. 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 2026 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.

Other News

Except for historical information, this news release may include forward-looking statements (within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934) including, without limitation, statements reflecting our current expectations about the future performance of our company or our business segments or about future market conditions. These statements are subject to certain risk factors that could cause actual results to differ materially. Various risk factors that could affect future results are listed in the company's filings with the Securities and Exchange Commission, including the Form 10-K Annual Report for the year ended December 31, 2025.
