RLI Corp. RLI

Company Overview

RLI Corp. is a U.S.-based specialty insurance holding company that underwrites property and casualty insurance through a portfolio of niche-focused insurance subsidiaries. The company operates within the specialty insurance segment of the broader property and casualty insurance industry, emphasizing underwriting profitability rather than premium volume growth. Its revenue is primarily generated through earned premiums and investment income from its insurance operations.

The company is known for its disciplined underwriting culture, decentralized operating model, and long-term focus on return on equity. RLI Corp. was founded in 1965 and became publicly traded in 1975. Over time, it evolved from a regional insurer into a nationally recognized specialty insurance provider by expanding into underserved and complex insurance niches where pricing and risk selection are critical competitive advantages.
