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 HK$. 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 HK$50.28B HK$48.30B
Net income Reported net income HK$3.84B HK$3.14B
Total assets Year-end reported balance HK$84.46B HK$82.95B
Shareholders’ equity Year-end reported balance HK$46.57B HK$43.80B
Net margin Net income ÷ revenue 7.64% 6.49%
Asset turnover Revenue ÷ total assets 0.5953x 0.5823x
Equity multiplier Total assets ÷ shareholders’ equity 1.8136x 1.8939x
ROE Net margin × asset turnover × equity multiplier 8.25% 7.16%

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 HK$50.28B
Prior annual revenue HK$48.30B
EBIT HK$5.75B
Tax rate 20.61%
NOPAT = EBIT × (1 − tax rate) HK$4.57B
Forecast start-growth basis 4.10%
Forecast policy latest reported annual revenue growth, bounded to -10.00% / 15.00%

Step 2 — Calculate FCFF

Current FCFF building block Value
NOPAT HK$4.57B
Add: depreciation & amortisation HK$5.70B
Less: capital expenditure -HK$5.89B
Less/(add): working-capital cash-flow movement -HK$422.91M
Current unlevered FCFF HK$3.95B

Explicit FCFF forecast

Forecast year Revenue growth NOPAT D&A Capex Change in NWC FCFF Present value
1 4.10% HK$4.75B HK$5.93B -HK$6.13B -HK$440.25M HK$4.11B HK$3.99B
2 3.70% HK$4.93B HK$6.15B -HK$6.31B -HK$456.54M HK$4.32B HK$3.93B
3 3.30% HK$5.09B HK$6.35B -HK$6.46B -HK$471.61M HK$4.51B HK$3.87B
4 2.90% HK$5.24B HK$6.54B -HK$6.59B -HK$485.29M HK$4.70B HK$3.79B
5 2.50% HK$5.37B HK$6.70B -HK$6.70B -HK$497.42M HK$4.87B HK$3.69B

Step 3 — Determine the Discount Rate (WACC)

WACC input Value
Risk-free rate 4.71%
Equity risk premium assumption 5.50%
Beta 0.60
Cost of equity 8.03%
Pre-tax cost of debt 3.66%
WACC 6.36%
WACC validation requires assumption review

Step 4 — Estimate Terminal Value

Terminal-value input Value
Perpetuity growth rate 2.50%
Terminal value HK$129.30B
Implied terminal EV / EBITDA 9.60x
Terminal value as % of enterprise value 83.14%

Step 5 — Discount Cash Flows to Enterprise Value

Enterprise-value component Value
Present value of explicit FCFF HK$19.26B
Present value of terminal value HK$94.98B
Indicated enterprise value HK$114.25B
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 HK$114.25B
Less: gross interest-bearing debt HK$16.89B
Add: cash and equivalents HK$13.08B
Add: affiliate investments HK$0.00
Less: minority interests HK$577.96M
Indicated common equity value HK$109.86B

Step 7 — Calculate Indicative Value Per Share

Per-share output Value
Shares used 1,811,124,000.00
Share-count basis reported shares outstanding; option/RSU dilution data not separately available
Current market price HK$7.34
DCF indicative value per share HK$60.66
Indicative value vs. market price 726.38%

Data lineage: Yahoo Finance public market and reported-statement data; retrieval timestamp: 2026-08-18 17:05:04.266759 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.

Estimation input Value
Regional factor set Asia Pacific ex Japan
Factor-return currency USD
Issuer-return basis USD adjusted total return
Estimation window 2025-08-20 to 2026-06-30
Aligned daily observations 210
Minimum observation requirement 120
Currency conversion for HK listings HKD adjusted close divided by daily USD/HKD close before simple daily return calculation

Fama–French Three-Factor and Five-Factor Results

Adjusted R² 0.08 0.07
Annualised residual volatility 32.13% 32.11%
Factor loading (t-statistic) FF3 FF5

Profitability (RMW) NM -0.16 (-0.44)
Investment (CMA) NM -0.01 (-0.03)

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.
