Company overview

21ST CENTURY INSURANCE GROUP

21ST CENTURY INSURANCE GROUP operates as a multi-line insurer focused on property and casualty coverage, offering homeowners, auto, and specialty policies that aim to protect individuals and small businesses from everyday perils and unexpected weather events. With roots in the broader insurance landscape defined by the fire, marine, and casualty SIC codes, the company targets consumers who seek bundled protection plus digital convenience for filing claims and managing renewals. Its underwriting discipline prioritizes risk-adjusted pricing, yet the firm still navigates material risks including catastrophe exposure, fluctuating reinsurance costs, and regulatory scrutiny tied to solvency, consumer protection, and rate filing approvals—especially as evolving climate factors pressure loss assumptions. Trading remains private, but stakeholders can track public disclosures through the federal filings associated with CIK 100331 while noting that the latest filing is currently unknown; stay informed by viewing live SEC filings on Earnings Feed.
