Net Operating Profit After Tax NOPAT
A company's core operating profit after taxes, before any effect of how it is financed.
What it is
NOPAT is the profit a company would earn from its operations if it had no debt — operating income (EBIT) minus the taxes on that operating income. It strips out interest expense so the figure reflects business performance independent of the capital structure. It is the starting point for free cash flow to the firm and for return-on-capital measures.
Why it matters
Because NOPAT ignores financing, it lets you compare the operating quality of companies with very different debt levels on equal footing. It is also the numerator in return on invested capital (ROIC), a key gauge of how efficiently a company turns capital into profit.
How it's calculated
Multiply operating income (EBIT) by one minus the effective or marginal tax rate. The tax adjustment uses the operating tax rate, not the company's reported tax line, because that line is affected by interest deductions.
How Quintarthai uses it
Operating income and effective tax rates needed to compute NOPAT are shown on each company's Financials and Ratios tabs, where return-on-capital metrics are also displayed.
