DuPont Model Analysis

The DuPont model decomposes return on equity (ROE) into three operating and capital-structure drivers:

ROE = Net Margin × Asset Turnover × Equity Multiplier

The comparison uses the latest two comparable annual periods available for the issuer, with reported statement amounts shown in US$. Revenue and net income are income-statement flows; total assets and shareholders’ equity are year-end balance-sheet figures. This is a simplified year-end-balance DuPont comparison rather than an average-balance ROE calculation.

DuPont component Calculation FY2025 FY2024
Revenue Reported revenue $17.18B $15.70B
Net income Reported net income $3.69B $2.65B
Total assets Year-end reported balance $50.78B $48.97B
Shareholders’ equity Year-end reported balance $9.35B $6.12B
Net margin Net income ÷ revenue 21.51% 16.91%
Asset turnover Revenue ÷ total assets 0.3383x 0.3206x
Equity multiplier Total assets ÷ shareholders’ equity 5.4303x 7.9995x
ROE Net margin × asset turnover × equity multiplier 39.51% 43.36%

Source: Yahoo Finance annual statements. Values are based on the two latest comparable annual periods returned by the source; fiscal period labels use the statement period-end year.

2.5 FCFF DCF Valuation

FCFF DCF exception: FCFF DCF is not the primary valuation method for financial institutions or REITs. This post deliberately does not publish a mechanical enterprise value or implied per-share value on an unsuitable basis.

Available valuation input Value
Last market price $347.15
Market capitalisation $73.64B
Revenue $17.18B
EBIT $5.57B
Reported free cash flow $3.22B

Buffett-inspired cash-quality checks not rated — FCFF DCF suitability or data-integrity condition not met
Lynch-inspired balance-and-growth checks not rated — FCFF DCF suitability or data-integrity condition not met

Data lineage: Yahoo Finance public market and reported-statement data; retrieval timestamp: 2026-08-18 17:22:38.036418 UTC; latest reported fiscal period: 2025-12-31 00:00:00. Financial institutions and REITs require sector-specific methods rather than a mechanical FCFF DCF. This is research and analysis only, not personalized financial advice.

2.7 Quantitative Factor Diagnostics

Model basis: Daily issuer USD excess returns are regressed in-sample using ordinary least squares on matching regional Fama–French factors. FF3 estimates market, size, and value loadings; FF5 adds profitability and investment. Coefficients are descriptive historical exposures, not predictions.

Estimation input Value
Regional factor set US
Factor-return currency USD
Issuer-return basis USD adjusted total return
Estimation window 2025-08-19 to 2026-06-30

Minimum observation requirement 120
Currency conversion for HK listings not required

Fama–French Three-Factor and Five-Factor Results

Diagnostic FF3 FF5
Annualised alpha -13.10% -2.23%
Adjusted R² 0.02 0.06
Annualised residual volatility 24.27% 23.70%
Factor loading (t-statistic) FF3 FF5
Market excess return (Mkt-RF) -0.19 (-1.35) 0.06 (0.37)
Size (SMB) 0.34 (1.77) 0.36 (1.75)
Value (HML) 0.12 (0.71) -0.13 (-0.66)
Profitability (RMW) NM 0.44 (2.58)
Investment (CMA) NM 0.38 (1.29)

Definitions: Mkt-RF is the market return less the risk-free rate; SMB is small minus big; HML is high minus low book-to-market; RMW is robust minus weak profitability; CMA is conservative minus aggressive investment. Factor returns are sourced from the Kenneth R. French Data Library; issuer adjusted-return history is sourced from Yahoo Finance. For Hong Kong listings, adjusted HKD prices are converted into USD with daily USD/HKD closes before return calculation to match the USD regional factor basis. This is an in-sample historical regression; coefficients and t-statistics do not establish causation or predict future returns. This is research and analysis only, not personalized financial advice.
