Is RLI a Buy? What to Consider in 2026
Last updated July 2026
Short answer
The bull case for RLI Corp underwrites specialty property (RLI) rests on Underwriting discipline and long profit streak: RLI recorded its 30th straight year of underwriting profitability in 2025 on an 83.6 combined ratio, and Q1 2026 came in at 86.0. Revenue (TTM) is ~$1.8B. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: As a US-focused property and casualty insurer, RLI is exposed to catastrophe losses from hurricanes, earthquakes, and severe weather, which can cause quarter-to-quarter earnings swings. Whether RLI is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.
RLI Corp underwrites specialty property, casualty, and surety insurance in the United States, focusing on hard-to-place niche risks that standard carriers often avoid. It operates across the excess and surplus (E&S) and specialty admitted markets through three reportable segments: casualty (commercial excess, personal umbrella, general liability, transportation, and management liability), property (commercial fire, hurricane, earthquake, difference-in-conditions, and marine), and surety (specialty bonding). Its business is geographically broad within the US but not globally diversified, which gives it depth in domestic specialty lines while leaving it exposed to US legal, catastrophe, and economic conditions. The investment picture centers on underwriting discipline. RLI posted its 30th consecutive year of underwriting profitability in 2025, with a combined ratio of 83.6 (below 100 means underwriting profit), and it has increased its regular dividend for 50 straight years while also paying periodic special dividends. Growth is deliberately measured, premium growth ran in the low single digits in early 2026, and the stock usually carries a premium valuation because that consistency is widely recognized. The main swing factors are catastrophe losses, pricing cycles in specialty lines, and investment income from its bond portfolio.
What's the case for buying RLI?
1. Underwriting discipline and long profit streak
RLI recorded its 30th straight year of underwriting profitability in 2025 on an 83.6 combined ratio, and Q1 2026 came in at 86.0. This durable underwriting margin, rather than premium volume, is the core of the company's earnings and the reason it has compounded book value steadily over decades.
2. Rising net investment income
Net investment income grew about 15% year over year in Q1 2026 as higher interest rates lifted yields on the bond portfolio and reinvestment continued at attractive levels. Investment income is a meaningful and relatively stable earnings contributor that complements underwriting results.
3. Dividend consistency and capital returns
RLI has raised its regular dividend for 50 consecutive years and has paid dividends for nearly 200 consecutive quarters. It supplements the modest regular payout (yield around 1.1%) with periodic special dividends, including a $2.00 per share special dividend paid in December 2025, returning excess capital when underwriting and investment results are strong.
4. Specialty and E&S market positioning
Operating in excess and surplus and specialty admitted lines lets RLI target niche risks with pricing flexibility and less direct competition from standard carriers. A firm specialty-lines pricing environment supports margins, though growth is intentionally selective rather than aggressive.
What are the risks to RLI?
As a US-focused property and casualty insurer, RLI is exposed to catastrophe losses from hurricanes, earthquakes, and severe weather, which can cause quarter-to-quarter earnings swings. Casualty reserves carry the risk of adverse development and social inflation (rising litigation and jury-award costs). The insurance pricing cycle can soften, compressing margins across specialty lines, and investment income depends on interest rates and credit conditions. The stock frequently trades at a premium valuation relative to book value and peers, so multiple compression is a risk if underwriting results normalize. RLI's lack of geographic diversification outside the US concentrates its exposure to domestic legal and economic conditions.

How do you decide if RLI is a buy?
Rather than asking whether RLI is a buy in the abstract, it tends to help to answer four questions:
- Thesis: do you believe the case above, and is it still true today?
- Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
- Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
- Overlap: check whether you already hold RLI indirectly through an index or sector ETF before adding more.
