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 $3.46B $3.27B
Net income Reported net income $483.20M $505.00M
Total assets Year-end reported balance $6.93B $6.75B
Shareholders’ equity Year-end reported balance $4.03B $3.79B
Net margin Net income ÷ revenue 13.98% 15.45%
Asset turnover Revenue ÷ total assets 0.4991x 0.4846x
Equity multiplier Total assets ÷ shareholders’ equity 1.7199x 1.7776x
ROE Net margin × asset turnover × equity multiplier 12.00% 13.31%

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 $3.46B
Prior annual revenue $3.27B
EBIT $697.00M
Tax rate 23.70%
NOPAT = EBIT × (1 − tax rate) $531.81M
Forecast start-growth basis 5.77%
Forecast policy latest reported annual revenue growth, bounded to -10.00% / 15.00%

Step 2 — Calculate FCFF

Current FCFF building block Value
NOPAT $531.81M
Add: depreciation & amortisation $206.50M
Less: capital expenditure -$63.60M
Less/(add): working-capital cash-flow movement -$54.10M
Current unlevered FCFF $620.61M

Explicit FCFF forecast

Forecast year Revenue growth NOPAT D&A Capex Change in NWC FCFF Present value
1 5.77% $562.51M $218.42M -$67.27M -$57.22M $656.44M $627.74M
2 4.95% $590.38M $229.24M -$110.26M -$60.06M $649.30M $567.80M
3 4.14% $614.80M $238.72M -$156.12M -$62.54M $634.86M $507.69M
4 3.32% $635.20M $246.65M -$203.98M -$64.62M $613.25M $448.47M
5 2.50% $651.08M $252.81M -$252.81M -$66.23M $584.85M $391.11M

Step 3 — Determine the Discount Rate (WACC)

WACC input Value
Risk-free rate 4.71%
Equity risk premium assumption 5.50%
Beta 0.98
Cost of equity 10.08%
Pre-tax cost of debt 3.36%
WACC 9.35%
WACC validation within standard range

Step 4 — Estimate Terminal Value

Terminal-value input Value
Perpetuity growth rate 2.50%
Terminal value $8.75B
Implied terminal EV / EBITDA 7.91x
Terminal value as % of enterprise value 68.75%

Step 5 — Discount Cash Flows to Enterprise Value

Enterprise-value component Value
Present value of explicit FCFF $2.54B
Present value of terminal value $5.59B
Indicated enterprise value $8.14B
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 $8.14B
Less: gross interest-bearing debt $1.85B
Add: cash and equivalents $580.00M
Add: affiliate investments $0.00
Less: minority interests -$1.30M
Indicated common equity value $6.87B

Step 7 — Calculate Indicative Value Per Share

Per-share output Value
Shares used 75,300,000.00
Share-count basis reported diluted weighted-average shares
Current market price $234.32
DCF indicative value per share $91.23
Indicative value vs. market price -61.07%

Perpetuity growth is below WACC pass
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 17:37:34.734019 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

Profitability (RMW) NM 0.20 (1.51)
Investment (CMA) NM 0.88 (3.92)

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.
