High Margin Businesses — US Stocks with Net Margin Above 20% on NYSE & NASDAQ

Net margin = Net Income / Revenue × 100. A 20% net margin means the company keeps 20 cents of profit from every dollar of revenue after paying all costs — production, operations, interest, and taxes. This is elite territory: the S&P 500 average net margin is approximately 8-12%. Businesses above 20% almost always have structural competitive advantages protecting their extraordinary profitability.

Pricing power (customers pay premium prices because the product or service is essential and differentiated), network effects (value increases with scale creating barriers to competition), intellectual property (patents, proprietary technology blocking imitation), regulatory moats (licensed monopolies, exclusive certifications), brand premium (consumer willingness to pay above commodity prices for trust and identity), and structural cost advantages (lowest-cost production through scale or proprietary processes).

Technology software (particularly mature SaaS platforms: gross margins 70%+, scale drives net margins 20-40%), pharmaceuticals (patent-protected branded drugs: 20-35% net margins), luxury goods (pricing power from brand exclusivity: 15-25%), payment networks (Visa, Mastercard: 50%+ net margins from toll-road economics), and financial services (asset management, exchanges). Capital-intensive sectors (manufacturing, retail, airlines) structurally cannot achieve 20% net margins.

EBITDA margin = EBITDA / Revenue (before interest, taxes, depreciation, amortization). Net margin = Net Income / Revenue (after all deductions). Net margin is more conservative and realistic — it accounts for the actual tax and interest burden. EBITDA margin is useful for comparing operating profitability across different capital structures. For asset-light businesses, both are similar; for capital-intensive businesses, net margin is significantly lower than EBITDA margin due to depreciation and interest charges.

For businesses with genuine structural moats, yes — many technology and consumer brand businesses have sustained 20%+ net margins for decades. Microsoft's net margin has exceeded 30% consistently in recent years. Visa has maintained 50%+ net margins for years. The key is whether the competitive advantage protecting the margins is structural (embedded switching costs, network effects, irreplaceable IP) or cyclical (favorable commodity prices, low competition temporarily). Structural advantages sustain margins; cyclical advantages do not.

Warren Buffett's moat framework essentially measures the width of the competitive advantage by the sustainability of above-average returns. High net margins (above 20%) are the financial expression of a wide moat — if a business earns 25% net margins in a competitive market, competitors would enter and compete margins down to average (8-12%) unless genuine barriers prevent them. Sustained high margins prove the moat is real.

Competition targets high-margin industries specifically because the returns attract capital. If the moat is genuinely structural (Microsoft's OS ecosystem, Visa's network), competition doesn't materially compress margins even after decades. If the moat is weaker (regulatory protection that expires, temporary technology lead), competition eventually erodes margins. The trajectory of margins over 3-5 years is the most direct evidence of moat strength — stable or expanding margins confirm the moat; gradually declining margins suggest erosion.

This screen uses 20% as an absolute filter — it doesn't adjust for sector. In some sectors (software, pharma), 20% is below average. In others (retail, industrials), 20% would be extraordinary. The screen captures the businesses that achieve 20%+ regardless of their sector's structural economics — these are the absolute premium margin leaders across US equities. For within-sector analysis, compare to sector-average net margins.

Net margin above 20% confirms the income statement is exceptional. ROCE above 15% confirms the balance sheet is also working efficiently — the high margins are generating genuine capital returns, not just accounting profits. Some businesses have high net margins but low ROCE because they require massive capital to sustain those margins (chip fabs, capital-intensive processes). The combination screens for businesses where both the profitability AND capital efficiency are premium.

Yes, rationally. A 25% net margin business is more valuable per dollar of revenue than a 5% margin business — each revenue dollar generates 5× more profit. Markets reflect this: high-margin businesses typically trade at premium P/E multiples. The investment opportunity arises when high-margin businesses trade at below-premium multiples due to temporary pessimism — the EBITDA Margin Above 30% screen combined with a P/E below 20 filter specifically targets this combination.
