Rating signals insurance-industry-leading operational performance and ability to support customers

DENVER — April 11, 2024 — Pinnacol Assurance has again achieved an AM Best rating of A- (excellent) with a stable outlook, demonstrating the company's commitment to being a critical and relied-upon partner for Colorado's workers, employers and the communities that it serves. This rating highlights Pinnacol's strong financial position, which enables the organization to provide workers' compensation insurance to more than 50,000 employers in Colorado and serve as the state’s “carrier of last resort.” Pinnacol has achieved an A- rating for nine consecutive years since it began participating in the rating program in 2015. 

Pinnacol Assurance is a top-performing workers' compensation insurance provider. In Colorado and nationwide, Pinnacol is dedicated to supporting and investing in the workforce – ensuring all injured workers have access to the care they need and that employers have access to reliable and affordable workers’ compensation insurance. While maintaining its A- rating, Pinnacol recently celebrated the highest policyholder and injured worker satisfaction scores in the state, all while investing in customized safety solutions and a comprehensive return to work program that helps our customers reduce risk and save costs. Achieving an A.M. Best rating of A- is a testament to Pinnacol's stability and ability to fulfill its mission.

AM Best assigns ratings to more than 3,500 insurance companies globally. The company’s rating process involves a combination of quantitative and qualitative analysis, which includes a review of financial statements, regulatory filings, and other data. The analysis also takes into account factors such as industry trends, competitive landscape, and regulatory environment.
