About the metric
What net debt means
Net debt compares a company’s interest-bearing debt with its cash and cash equivalents. Positive net debt means debt exceeds cash, while a negative value indicates the company has more cash than debt on this measure.
Calculation and source
How net debt is calculated
TickerStat calculates net debt as total interest-bearing debt minus cash and cash equivalents at the same reporting-period end. Short-term investments are not subtracted because they are not included in the standardized cash series. Fiscal periods can differ from calendar years, so exact period-end dates are included.
