What Amerisure Insurance does

Amerisure Mutual Insurance Company is a Farmington Hills, Michigan-based commercial property and casualty insurer founded in 1912, operating as a policyholder-owned mutual licensed in all 50 U.S. states. The company focuses on mid-market commercial accounts in four primary verticals — construction, manufacturing, healthcare, and wholesale/distribution — offering Workers' Compensation, Commercial Auto, General Liability, Umbrella, Commercial Property, Inland Marine, Loss Sensitive, and Surety products, augmented by specialized programs such as Contractors Advantage Program (CAP), Manufacturers Advantage Program (MAP), and Amerisure COMMAND Coverage. Through its Amerisure Programs (AMP) division, Amerisure also writes niche verticals (gas & welding, security guards, tow operators, swimming pool contractors, equipment rental, condominium associations) via exclusive managing general agent relationships.

Amerisure generates revenue through commercial insurance premiums and distributes exclusively through the Partners For Success® network — a curated set of elite independent agencies selected for vertical expertise and market leadership, with no direct-to-consumer or online quoting channel. Customer-facing technology is anchored on the SureConnect® digital portal (policy, billing, claims, risk management) and SureClaims™ service, supplemented by risk management technology including Fleet Alliance telematics partnerships, AI-powered ergonomic evaluations, Fit for Duty impairment screening, VR safety training, wearables, and IoT hazard sensors.

The company maintains an A.M. Best "A" (Excellent) financial strength rating, reports a policyholder NPS of 80, and has operated continuously for over 110 years under a mutual holding structure adopted in 2009. Recent strategic actions include the 2026 transfer of legacy asbestos liabilities to Compre Group to free capital, ongoing Guidewire cloud platform modernization (2025 Innovation Award), and active scaling of risk management technology partnerships (GPS Insight, National Safety Council MSD Solutions Lab). A pending coverage dispute with Mycon General Contractors over facade failure claims and continued investment in risk technology are the principal litigation and operational variables to monitor.

Direct peers

• Donegal Group: Donegal is a regional P&C insurer with significant commercial lines emphasis distributed through independent agents, including a workers' comp focus that overlaps Amerisure's WC product. Comparable on agency distribution model and mid-market commercial orientation.
• Selective Insurance Group: Selective Insurance is a mid-market commercial P&C specialist distributed through independent agents, with emphasis on construction, manufacturing, and similar core verticals that overlap directly with Amerisure's segment focus. Publicly traded, but with comparable E&S-flavored specialty commercial positioning.
• Employers Holdings: Employers is a workers' compensation specialist carrier with strong small and mid-market focus, comparable to Amerisure on the workers' comp product line. As a monoline WC specialist, it is a partial direct peer rather than a full multi-line match.
• Main Street America Insurance: Main Street America is a mutual holding company writing small and mid-market commercial and personal lines through independent agents. Its mutual structure and small/mid-commercial orientation make it a relevant structural peer to Amerisure.
• FCCI Insurance Group: FCCI is a mutual commercial P&C insurer focused on construction, manufacturing, and service industries — a near-direct vertical overlap with Amerisure. Its mutual structure and industry-specialized commercial book make it a highly comparable peer, particularly for the construction and manufacturing segments.
• Cincinnati Financial: Cincinnati Financial is a publicly traded specialty commercial P&C insurer with a long-standing independent agency distribution model and significant concentration in mid-market commercial lines. It is a relevant direct peer due to comparable agency-channel strategy and mid-market commercial orientation, though it operates as a stock company rather than a mutual.
• Westfield Insurance: Westfield is a super-regional mutual P&C carrier that writes commercial lines through independent agents, with significant specialty and middle-market exposure. Its mutual ownership structure and agent-distributed specialty commercial book make it one of the closest operating-model peers to Amerisure.
• The Hanover Insurance Group: Hanover is a specialty commercial P&C carrier with strong mid-market and small-commercial focus, distributed primarily through independent agents. Comparable to Amerisure on product mix (commercial auto, GL, workers' comp, umbrella) and agency distribution, though Hanover is publicly traded and geographically broader.

Broad incumbents

• Travelers: Travelers is one of the largest US commercial P&C carriers with extensive mid-market and construction industry programs. It is a broader incumbent offering overlapping coverage (workers' comp, GL, commercial auto, surety) to the same customer base, but at materially greater scale and breadth.
• Chubb: Chubb is a global P&C and specialty insurer offering commercial multi-line coverage to mid-market and large accounts, including construction and manufacturing segments. It competes with Amerisure at the upper end of the mid-market but operates as a much larger global incumbent.
