ROIC vs return on equity
Return on Equity (ROE) is calculated as net income / equity — it is capital-structure dependent, rising automatically with leverage even without any improvement in operating performance. A company can boost ROE by taking on debt without improving its underlying operations, making ROE a misleading measure of operational excellence. ROIC is capital-structure neutral: by using NOPAT (which excludes interest) and invested capital (which includes all capital, debt and equity), ROIC isolates whether the underlying business generates attractive returns, independent of how it is financed. The link to value creation: Economic Value Added (EVA) = Invested Capital × (ROIC − WACC). Positive EVA = value created; negative EVA = value destroyed, even in a "profitable" company.
What drives high ROIC
Sustainably high ROIC (20%+) requires genuine competitive advantages — economic "moats" that prevent competitors from replicating the business model and driving ROIC toward the cost of capital. Michael Porter’s five forces and Warren Buffett’s moat framework both describe the same ROIC phenomenon from different angles. Network effects (social media, payments): each additional user makes the platform more valuable, creating compounding switching costs. Scale economies: cost per unit falls with volume, making it harder for smaller competitors to match margins. Intangible assets: brands (LVMH), patents (pharma), regulatory licences. Switching costs: enterprise software creates deep switching costs — the customer faces high integration cost and disruption risk. Companies with durable moats maintain high ROIC over decades; companies without them see ROIC revert toward WACC as competition erodes excess returns.
“ROIC is the heart of investing. The price you pay matters, but ultimately, what a business earns on the capital it deploys determines whether ownership is rewarding. Everything else is noise.”
What this means for you
When evaluating an investment in a company, ROIC-versus-WACC is the central question. Companies sustaining ROIC well above their cost of capital — genuinely excellent businesses — deserve premium multiples. The PE/B ratio of exceptional businesses like Visa, MSCI, or S&P Global reflects market recognition of their extraordinarily high and durable ROIC, not mere speculation. Conversely, industries with structural ROIC below WACC (airlines, commodity chemicals, steel) have historically been poor long-term investments despite occasional tactical opportunities. McKinsey’s Valuation textbook is the canonical reference on ROIC and value creation — the authors demonstrate empirically that ROIC and growth together explain virtually all variation in company valuation multiples.
