Revenue minus cost of goods sold. Graham's ≥40% threshold identifies businesses with durable pricing power. Note: software and financial companies naturally exceed this; retailers and manufacturers rarely reach it due to their cost structures.
Operating Margin16.6%
Profit after operating costs before interest and taxes. A consistent ≥15% operating margin signals a business with real competitive advantages. Capital-intensive industries (airlines, auto, commodities) rarely hit this threshold due to their structural cost base — compare within industry for context.
Net Income Margin10.8%
Bottom-line profit as a percentage of revenue. The ≥20% target reflects Buffett's preference for highly profitable businesses. Financial engineering (buybacks, tax optimisation) can inflate this temporarily — look for consistency across multiple years rather than a single strong result.

A
Years to Pay Off Debt1.0 yrs
Total Debt ÷ Net Income. Lower = stronger balance sheet. Important caveat: utilities, telecoms, REITs, and infrastructure companies carry large structural debt by design — their bond-like cash flows service it comfortably at ratios that would alarm Graham. Compare within sector.
Working Capital vs Long-Term Debt$666M
Working Capital minus Long-Term Debt. Negative results are common and expected in capital-return-focused businesses like Apple, Domino's, and McDonald's — where aggressive buybacks and dividends intentionally reduce book equity. This does not indicate financial distress in high-FCF businesses.
Working Capital$750M
Current Assets minus Current Liabilities. Negative working capital can be a deliberate efficiency strategy in businesses that collect cash before paying suppliers (retailers, fast food franchises, subscription businesses). Assess alongside free cash flow generation for full context.
Valuation
F
Margin of Safety0.0%
How far below the Graham Number the stock trades. Graham required a 33% discount as a buffer against analytical error. However, the Graham Number itself assumes 1960s-era P/E and P/B norms — for modern asset-light businesses it often understates true intrinsic value, making 0% MoS appear misleadingly bad.
Price-to-Book3.14x
Market price vs book value per share. Rarely below 1.5x for quality businesses today. Intangible assets (brand, software, patents) don't appear on the balance sheet under accounting rules, making P/B artificially high for asset-light companies like software and consumer brands.
Cash Flow
B
Free Cash Flow$120M
Operating cash flow minus capital expenditures. Buffett's most important metric — cash a business actually generates for its owners after maintaining and growing its asset base. Consistently positive FCF is one of the strongest indicators of a durable, well-run business regardless of accounting profits.
CapEx % of Net Income27.3%
Capital expenditure as a share of net income. Low CapEx signals a capital-light business that doesn't need heavy reinvestment to sustain earnings — Buffett's ideal. High CapEx is structurally necessary in manufacturing, airlines, telecoms, and semiconductors. For these industries, a high reading reflects the business model, not poor management.
Owner Earnings$200M
Net Income + Depreciation & Amortisation − Capital Expenditures. Buffett's preferred measure of a company's true annual earning power — what could theoretically be distributed to owners without impairing the business. More reliable than reported EPS because it accounts for the capital cost of maintaining the business.

Metric Explanations
What each dimension measures and where the thresholds come from.
Gross Profit Margin
Revenue minus cost of goods sold. Graham's ≥40% threshold identifies businesses with durable pricing power. Note: software and financial companies naturally exceed this; retailers and manufacturers rarely reach it due to their cost structures.
Operating Margin
Profit after operating costs before interest and taxes. A consistent ≥15% operating margin signals a business with real competitive advantages. Capital-intensive industries (airlines, auto, commodities) rarely hit this threshold due to their structural cost base — compare within industry for context.
Net Income Margin
Bottom-line profit as a percentage of revenue. The ≥20% target reflects Buffett's preference for highly profitable businesses. Financial engineering (buybacks, tax optimisation) can inflate this temporarily — look for consistency across multiple years rather than a single strong result.
Years to Pay Off Debt
Total Debt ÷ Net Income. Lower = stronger balance sheet. Important caveat: utilities, telecoms, REITs, and infrastructure companies carry large structural debt by design — their bond-like cash flows service it comfortably at ratios that would alarm Graham. Compare within sector.
Working Capital vs Long-Term Debt
Working Capital minus Long-Term Debt. Negative results are common and expected in capital-return-focused businesses like Apple, Domino's, and McDonald's — where aggressive buybacks and dividends intentionally reduce book equity. This does not indicate financial distress in high-FCF businesses.
Working Capital
Current Assets minus Current Liabilities. Negative working capital can be a deliberate efficiency strategy in businesses that collect cash before paying suppliers (retailers, fast food franchises, subscription businesses). Assess alongside free cash flow generation for full context.
Margin of Safety
How far below the Graham Number the stock trades. Graham required a 33% discount as a buffer against analytical error. However, the Graham Number itself assumes 1960s-era P/E and P/B norms — for modern asset-light businesses it often understates true intrinsic value, making 0% MoS appear misleadingly bad.
Price-to-Book
Market price vs book value per share. Rarely below 1.5x for quality businesses today. Intangible assets (brand, software, patents) don't appear on the balance sheet under accounting rules, making P/B artificially high for asset-light companies like software and consumer brands.
Free Cash Flow
Operating cash flow minus capital expenditures. Buffett's most important metric — cash a business actually generates for its owners after maintaining and growing its asset base. Consistently positive FCF is one of the strongest indicators of a durable, well-run business regardless of accounting profits.
CapEx % of Net Income
Capital expenditure as a share of net income. Low CapEx signals a capital-light business that doesn't need heavy reinvestment to sustain earnings — Buffett's ideal. High CapEx is structurally necessary in manufacturing, airlines, telecoms, and semiconductors. For these industries, a high reading reflects the business model, not poor management.
Owner Earnings
Net Income + Depreciation & Amortisation − Capital Expenditures. Buffett's preferred measure of a company's true annual earning power — what could theoretically be distributed to owners without impairing the business. More reliable than reported EPS because it accounts for the capital cost of maintaining the business.
Mr. Market is currently offering Align Technology, Inc. at $182.08.
The business passes only 0 of 7 of Graham's defensive criteria — well below his required standard.
At $182.08, the stock trades at a 302% premium to its Graham Number of $45.24. Graham would consider this price speculative.
There is no margin of safety at the current price. Graham would advise patience and waiting for a better entry point.
Trading at 26.6x NCAV. Expected for most quality businesses — NCAV was designed to find depression-era bargains and rarely applies to modern profitable companies..
Conclusion: By Graham's standards, this stock is speculative at its current price. The intelligent investor would look elsewhere or wait.

📊Quarterly mode — Graham Fair Value & 7 Criteria require annual data. Switch to Annual for full analysis.
Quarter vs Same Quarter Last Year
YoY strips seasonality
Revenue Growth (YoY)
Prior year: $979M▲ $1.0B+6.2%
Revenue growth vs same quarter last year strips seasonality. Consistent double-digit growth is a Buffett hallmark.
Gross Margin
Prior year: 69.5%▲ 70.8%+1.4pp
Buffett: consistent gross margin above 40% signals durable pricing power and competitive moat.
Operating Margin
Prior year: 17.6%▲ 16.6%-1.0pp
Graham: operating margin reflects true business economics before financing. Trend matters as much as level.
Net Margin
Prior year: 9.5%▲ 10.8%+1.3pp
Net margin can be distorted by one-time items, tax timing, or interest costs — compare to operating margin for signal quality.
Quarterly Health Checks
3 Graham/Buffett criteria that are valid and reliable on quarterly data
✅ Adequate Size
Graham required scale for resilience. Quarterly revenue × 4 gives an annualised proxy.
$1.0B/qtr (≈$4.2B ann.)
vs > $1.5B annualised revenue
❌ Financial Condition
Current assets vs current liabilities — a real-time liquidity snapshot. Valid and reliable on quarterly data.
1.39x current ratio
vs ≥ 2.0x
✅ Free Cash Flow
Buffett's most important single metric. A positive FCF quarter means the business generated real cash for owners after maintaining its asset base.

ROIC

Based on latest annual operating income
Return on Invested Capital — Buffett's preferred measure for asset-light businesses. ROIC > 15% consistently signals a durable competitive advantage (moat). More meaningful than P/B for software, pharma, and consumer brand companies where most value is intangible and off-balance-sheet.
