RLI Corp. (RLI) is down after the company’s first-quarter 2026 earnings update highlighted a year-over-year decline in profitability and results that came in slightly below expectations on an adjusted basis. Net earnings were $54.9 million, or $0.60 per diluted share, down from $63.2 million, or $0.68 per share, in the prior-year quarter, while operating earnings were $0.83 per share versus $0.89 a year earlier. The quarter’s adjusted EPS came in below the 85-cent consensus estimate cited alongside the report coverage, increasing pressure on the stock. (investors.rlicorp.com)

A key focus in the release was underwriting profitability. RLI posted underwriting income of $57.8 million and a combined ratio of 86.0, compared with underwriting income of $70.5 million and a combined ratio of 82.3 in Q1 2025, signaling weaker core insurance margins even as results remained profitable. The report also disclosed $16.0 million of catastrophe losses net of reinsurance for the quarter, a headwind for underwriting results. (investors.rlicorp.com)

RLI’s net investment income increased 15% to $42.3 million, helping support operating results. However, comprehensive earnings dropped sharply to $29.5 million ($0.32 per share) from $93.2 million ($1.01 per share) a year earlier, reflecting unrealized fixed-income losses tied to rising interest rates.

With the quarterly print and earnings-call commentary arriving in the last few days (April 22–23, 2026), investors appear to be repricing RLI on near-term margin pressure and the modest miss versus adjusted EPS expectations, despite continued profitability and higher investment income. The stock’s decline also follows a period of broader weakness for the shares, including a fresh 52-week low reached earlier this week, which can amplify downside reactions after earnings. (wtop.com)
