As Salamu alaikum,
Are in a financial crisis, or at the time of the Corona Virus, many companies become not Sharia Comforn because of over-indebtedness?
That may have been a factor, but I think the issue had more to do with the market cap rather than the debt itself. The significant drop in market cap for many companies caused their debt-to-market cap ratio to exceed the threshold for shariah compliance, leading to the stock becoming non-compliant.
Have many Companies become Non Sharia Compliant at the Time of Corona?
