Atlas Financial Holdings, Inc. was a U.S. based financial services company that specialized in underwriting commercial automobile insurance policies, with a primary focus on the passenger transportation industry, including taxis, non-emergency para-transit, limousines, and livery services. The company aimed to be a leader in this niche market through its subsidiaries, such as American Country Insurance Company and American Service Insurance Company. After experiencing significant financial challenges related to adverse loss reserve development and deteriorating operating results, the company's stock was delisted from Nasdaq, and it ultimately filed for Chapter 11 bankruptcy protection in 2022 to facilitate a sale of its assets and wind down its operations.
