Debt Overhang is a situation where a company cannot take on any more debt, because their current debt load is too high. It can be caused by the company's inability to generate enough cash flow to pay off interest on existing debts.Debt overhang can be a problem for businesses, as they are unable to invest in new projects or acquisitions because they are limited by their existing debts. This limits the growth potential of the business, as it cannot take advantage of opportunities that arise.Debt overhang can also lead to bankruptcy if the company cannot repay its debts and has no other sources of revenue.
