Stonetrust Commercial Insurance Company

What Stonetrust Commercial Insurance Company does

Stonetrust Commercial Insurance Company is a privately held, specialty workers' compensation insurance carrier headquartered in Baton Rouge, Louisiana (re-domesticated to Nebraska in August 2016), serving more than 5,000 employers across 14 states in the South and Midwest (licensed in 28 total). Founded in 1993 as LACE-SIF and converted to its current form in 2006, the company has been owned by Francis Chou through Wintaai Holdings since March 2018 and upgraded to an A (Excellent) AM Best financial strength rating in August 2025. The company writes statutory workers' compensation and employers' liability coverage across six primary verticals — construction, wholesale, retail, manufacturing, healthcare, and service-related businesses — and operates a wholly-owned preferred-tier subsidiary, Stonetrust Premier Casualty Insurance Company, launched in 2022.

Stonetrust's operations are powered by Insurity's Workers' Comp Suite (implemented December 2021), which provides integrated agent and policyholder portals, complemented by the Zywave Safety Connection Portal for training and resources, and InvoiceCloud for payment processing. Revenue is generated through statutory workers' compensation premiums, typically bundled with employers' liability, priced via risk-based underwriting against employer payroll, industry classification, and claims history. The company writes no direct-to-consumer business; all distribution flows through a network of appointed independent insurance agencies in each operating state, compensated on a commission basis (e.g., 25% on new South Carolina business in 2026). Stonetrust reports 2023 written premiums of $52.4M, 2024 net income of $13.1M, and 2025 net income of $16.4M against a surplus of $166.1M and total assets of $278.8M.
