Steak 'n Shake has permanently closed 57 of its locations due to the economic impact caused by the COVID-19 outbreak. 

A financial report released by the burger chain's parent company, Biglari Holdings, stated that 51 company-owned restaurants closed down and 6 franchised locations. 

"The COVID-19 pandemic has adversely affected our operations and financial results," the company said in its report. "However, the COVID-19 pandemic could cause disruptions to our supply chain. Moreover, we cannot predict how the outbreak of COVID-19 will alter the future demand of our products."

The report did not list which locations were affected. 

Steak 'n Shake was suffering financially before the pandemic. Last year, the chain closed more than 100 locations.
