Core Specialty Insurance

What Core Specialty Insurance does

Core Specialty Insurance Holdings is a privately held specialty property and casualty insurer founded in 2020 from the recapitalization of StarStone US with capital from Enstar Group, Sixth Street, and Aquiline. Operating through six licensed insurance subsidiaries and 17 specialty divisions — spanning Property & Short-Tail (Agriculture Reinsurance, Aviation & Aerospace, Equine, Marine & Energy, Property), Specialty Casualty (Commercial Auto via Lancer Insurance, Contract Binding, D&O, E&O, Excess Casualty, Healthcare Professional Liability, Medical Stop-Loss, Primary Casualty, Workers' Compensation), and Bond/Credit & Guarantee (Financial Services, Mortgage Reinsurance, Surety) — the company writes both admitted and non-admitted business across all 50 states and D.C. Distribution is exclusively wholesale through approved brokers and independent agents, supported by the proprietary ESCAPE broker portal (a two-time Celent Model Insurer award winner hosted on Duck Creek SaaS via Microsoft Azure) that compresses quote-to-bind-to-issue from days to minutes.

The company generates revenue through risk-based insurance premiums priced by division underwriters, with policies issued through subsidiary platforms rated A (stable) or A- (stable) by AM Best. Core Specialty holds $1.41 billion in equity/surplus as of December 2024 and employs 1,001-5,000 people, making it the third-largest private company in Cincinnati. Growth has been driven by an aggressive M&A program — Lancer Insurance merger (Dec 2021), Hallmark Financial E&S operations ($59.9M, Oct 2022), American Surety ($93M GWP, Jun 2024), London Aviation Underwriters (Jan 2025), and Argo Professional Lines renewal rights (~$155M GWP, Jan 2025) — and the company was reported in June 2026 to be preparing a Q4 dual-track IPO. Customers are small to mid-sized businesses, self-funded employers, and niche vertical insureds served exclusively through wholesale brokers, with no retail consumer or large enterprise anchor relationships.
