Koppers Holdings debt-to-equity ratio trends
Over the last five fiscal years, Koppers Holdings's debt-to-equity ratio decreased from 2.57 to 1.78, a change of −0.79. The latest reported quarter, Q2 2026, shows 2.59.
What the debt-to-equity ratio means
The debt-to-equity ratio compares interest-bearing debt with shareholders’ equity. It helps show how much debt financing a company uses relative to its accounting equity, but useful comparison levels vary by industry.
How debt-to-equity is calculated
TickerStat calculates debt-to-equity as total interest-bearing debt divided by SEC-reported shareholders’ equity for the same balance-sheet date. Total liabilities are not treated as debt, and periods with non-positive equity are omitted. Fiscal periods can differ from calendar years, so exact period-end dates are included.
