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$2.28B HK$2.00B
Net income Reported net income HK$156.30M HK$769.60M
Total assets Year-end reported balance HK$4.62B HK$4.54B
Shareholders’ equity Year-end reported balance HK$-518.52M HK$-1.95B
Net margin Net income ÷ revenue 6.86% 38.46%
Asset turnover Revenue ÷ total assets 0.4933x 0.4406x
Equity multiplier Total assets ÷ shareholders’ equity -8.9079x -2.3241x
ROE Net margin × asset turnover × equity multiplier -30.14% -39.38%

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$2.28B
Prior annual revenue HK$2.00B
EBIT HK$464.51M
Tax rate 0.07%
NOPAT = EBIT × (1 − tax rate) HK$464.19M
Forecast start-growth basis 13.86%
Forecast policy latest reported annual revenue growth, bounded to -10.00% / 15.00%

Step 2 — Calculate FCFF

Current FCFF building block Value
NOPAT HK$464.19M
Add: depreciation & amortisation HK$113.64M
Less: capital expenditure -HK$21.04M
Less/(add): working-capital cash-flow movement HK$6.88M
Current unlevered FCFF HK$563.67M

Explicit FCFF forecast

Forecast year Revenue growth NOPAT D&A Capex Change in NWC FCFF Present value
1 13.86% HK$528.54M HK$129.40M -HK$23.96M HK$7.83M HK$641.81M HK$608.56M
2 11.02% HK$586.80M HK$143.66M -HK$55.86M HK$8.69M HK$683.30M HK$582.51M
3 8.18% HK$634.82M HK$155.42M -HK$92.10M HK$9.40M HK$707.54M HK$542.30M
4 5.34% HK$668.72M HK$163.72M -HK$130.37M HK$9.91M HK$711.98M HK$490.63M
5 2.50% HK$685.44M HK$167.81M -HK$167.81M HK$10.15M HK$695.60M HK$430.96M

Step 3 — Determine the Discount Rate (WACC)

WACC input Value
Risk-free rate 4.71%
Equity risk premium assumption 5.50%
Beta -0.11
Cost of equity 4.13%
Pre-tax cost of debt 13.86%
WACC 11.23%
WACC validation within standard range

Step 4 — Estimate Terminal Value

Terminal-value input Value
Perpetuity growth rate 2.50%
Terminal value HK$8.17B
Implied terminal EV / EBITDA 9.57x
Terminal value as % of enterprise value 64.39%

Step 5 — Discount Cash Flows to Enterprise Value

Enterprise-value component Value
Present value of explicit FCFF HK$2.65B
Present value of terminal value HK$4.80B
Indicated enterprise value HK$7.46B
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$7.46B
Less: gross interest-bearing debt HK$1.79B
Add: cash and equivalents HK$94.44M
Add: affiliate investments HK$0.00
Less: minority interests HK$0.00
Indicated common equity value HK$5.76B

Step 7 — Calculate Indicative Value Per Share

Per-share output Value
Shares used 28,085,805,149.00
Share-count basis reported diluted weighted-average shares
Current market price HK$0.40
DCF indicative value per share HK$0.20
Indicative value vs. market price -48.11%

Data lineage: Yahoo Finance public market and reported-statement data; retrieval timestamp: 2026-08-18 16:36:32.595881 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

Profitability (RMW) NM -0.48 (-0.68)
Investment (CMA) NM 0.36 (0.46)

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.
