The net debt to EBITDA ratio is popular with analysts because it takes into account a company's ability to decrease its debt. Ratios higher than 4 or 5 typically set off alarm bells because this indicates that a company is less likely to be able to handle its debt burden, and thus is less likely to be able to take on the additional debt required to grow the business. Ultimately, however, it depends on the benchmark of the industry you are looking at.
