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 $9.01B $7.00B
Net income Reported net income $3.51B $2.85B
Total assets Year-end reported balance $19.45B $14.04B
Shareholders’ equity Year-end reported balance $12.37B $9.99B
Net margin Net income ÷ revenue 38.99% 40.73%
Asset turnover Revenue ÷ total assets 0.4631x 0.4987x
Equity multiplier Total assets ÷ shareholders’ equity 1.5722x 1.4051x
ROE Net margin × asset turnover × equity multiplier 28.39% 28.54%

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

Valuation basis: This research model follows a five-year, unlevered FCFF DCF. It starts from reported annual operating inputs, forecasts revenue and operating cash conversion under an explicit mechanical policy, discounts FCFF at WACC, applies a Gordon-growth terminal value, and bridges enterprise value to an indicative common-equity value per share. It is an analytical estimate rather than a recommendation or personalised target price.

Step 1 — Forecast Operating Profit and NOPAT

Reported operating input Value
Revenue $9.01B
Prior annual revenue $7.00B
EBIT $3.86B
Tax rate 17.40%
NOPAT = EBIT × (1 − tax rate) $3.19B
Forecast start-growth basis 15.00%
Forecast policy latest reported annual revenue growth, bounded to -10.00% / 15.00%

Step 2 — Calculate FCFF

Current FCFF building block Value
NOPAT $3.19B
Add: depreciation & amortisation $72.60M
Less: capital expenditure -$119.50M
Less/(add): working-capital cash-flow movement $687.80M
Current unlevered FCFF $3.83B

Explicit FCFF forecast

Forecast year Revenue growth NOPAT D&A Capex Change in NWC FCFF Present value
1 15.00% $3.66B $83.49M -$137.43M $790.97M $4.40B $4.13B
2 11.88% $4.10B $93.40M -$138.66M $884.90M $4.94B $4.08B
3 8.75% $4.46B $101.58M -$134.39M $962.33M $5.39B $3.92B
4 5.62% $4.71B $107.29M -$124.62M $1.02B $5.71B $3.65B
5 2.50% $4.82B $109.97M -$109.97M $1.04B $5.87B $3.31B

Step 3 — Determine the Discount Rate (WACC)

WACC input Value
Risk-free rate 4.71%
Equity risk premium assumption 5.50%
Beta 1.61
Cost of equity 13.59%
Pre-tax cost of debt 7.71%
WACC 13.59%
WACC validation within standard range

Step 4 — Estimate Terminal Value

Terminal-value input Value
Perpetuity growth rate 2.50%
Terminal value $54.20B
Implied terminal EV / EBITDA 9.11x
Terminal value as % of enterprise value 60.03%

Step 5 — Discount Cash Flows to Enterprise Value

Enterprise-value component Value
Present value of explicit FCFF $19.08B
Present value of terminal value $28.66B
Indicated enterprise value $47.74B
Discounting convention mid-year for explicit FCFF; terminal value discounted at year-end five

Step 6 — Convert Enterprise Value to Equity Value

Equity bridge Value
Indicated enterprise value $47.74B
Less: gross interest-bearing debt $0.00
Add: cash and equivalents $10.74B
Add: affiliate investments $0.00
Less: minority interests $0.00
Indicated common equity value $58.48B

Step 7 — Calculate Indicative Value Per Share

Per-share output Value
Shares used 1,275,700,000.00
Share-count basis reported diluted weighted-average shares
Current market price $192.91
DCF indicative value per share $45.84
Indicative value vs. market price -76.24%

WACC is within the configured operating-company range pass
Terminal-year FCFF is positive pass

Data lineage: Yahoo Finance public market and reported-statement data; retrieval timestamp: 2026-08-18 17:22:33.376324 UTC; latest reported fiscal period: 2025-12-31 00:00:00. Default assumptions: five-year forecast, mid-year discounting for explicit FCFF, a maximum 2.50% perpetuity-growth rate below both WACC and the risk-free rate, historical operating-ratio persistence, and capex convergence to D&A by year five. No sell-side consensus or management guidance is substituted for reported inputs. 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.

Fama–French Three-Factor and Five-Factor Results

Diagnostic FF3 FF5
Annualised alpha 18.49% -6.45%
Adjusted R² 0.25 0.28
Annualised residual volatility 45.63% 44.43%
Factor loading (t-statistic) FF3 FF5
Market excess return (Mkt-RF) 1.90 (7.07) 1.40 (4.65)
Size (SMB) -0.66 (-1.81) -0.72 (-1.89)
Value (HML) -0.37 (-1.18) 0.08 (0.21)
Profitability (RMW) NM -0.92 (-2.89)
Investment (CMA) NM -0.61 (-1.11)

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.
