Sources and calculations
Financial inputs from company filings. Last checked Oct 18, 2026. A dash means missing inputs or an undefined calculation.
Period changes use the preceding fiscal quarter or year. Percentage changes divide by the absolute prior value; a zero or missing baseline has no percentage change. Percentage metrics show changes in percentage points.
Quarterly returns use trailing 12-month earnings and period-end balances averaged with the same fiscal quarter one year earlier. NOPAT uses the reported effective tax rate only when pretax profit is positive and the rate is between 0 and 100%. WACC starts at 7.7%, rounded from the US nonfinancial market · generic proxy benchmark in NYU Stern · January 2026. It is an editable US sector proxy applied across history, not a company estimate; foreign reporting currencies also need a currency-specific assessment.

- ROIC
- NOPAT / average invested capital × 100. NOPAT = operating income × (1 − effective tax rate). Invested capital = equity including noncontrolling interests + debt − cash and equivalents. Average uses period end and one year earlier.
- ROCE
- Operating income / average (assets − current liabilities) × 100, using period end and one year earlier.
- ROIIC
- Year-over-year change in annual/TTM NOPAT / positive year-over-year change in invested capital × 100. Capital reductions and missing inputs yield unavailable values.
- ROE
- Earnings attributable to owners / average equity attributable to owners × 100, using period end and one year earlier.
- ROA
- Net income / average total assets × 100, using period end and one year earlier.
- ROIC − WACC
- ROIC less your WACC assumption, in percentage points. The same scenario rate is applied across history; it is not a reported or historical company WACC.
