Valuation

Bull case: the Growth Earnings group reads highest at a median of HK$77.67 per share, and 3 of the 16 models we run sit above the HK$63.00 price.

Bear case: the Asset-Based group reads lowest at HK$10.99, and 13 of the 16 models stay below the price. Evidence for this calculation is high.

Scenario range: HK$32.32 (bear) to HK$53.86 (bull), the price of HK$63.00 sits above it. Bear and bull are the same models on cautious and optimistic assumptions, a range, not a price target.

Quality & growth

The Quality Score stands at 33/100 (below-average quality), in the Consumer Cyclical sector.

Expensive Growth: The company is growing, but growth may require heavy reinvestment or weak cash conversion.

Fair Value models

Bear HK$32.32 Fair Value HK$43.09 Bull HK$53.86
Model ⓘEach model values the company its own way (discounted cash flow, earnings, assets, dividends). The fair value above is their evidence-weighted blend, not the output of a single model. Based on fiscal year 2025 figures (about 9 months old). Earnings retained since then (HK$2.30 per share) are deliberately not added. Bear ⓘBear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull ⓘBull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. If a model's bull case is above four times its base value, the table shows that limit with a > sign (like the overall Bull above): beyond it no assumption holds. Evidence ⓘEvidence = how well-backed THIS model's estimate is for this stock (0–100): how complete and reliable its input data are, and how well the model fits the company. The final Fair Value is an evidence-weighted blend, so better-evidenced models count more. Green ≥70, amber 50–69, grey below 50.

Revenue & earnings trend

Growth Quality ⓘGrowth is valuable only when reinvestment earns attractive returns (Aswath Damodaran): sustainable growth depends on return on capital, reinvestment and efficiency. Basis: total company revenue over the periods shown on the cards (3Y/5Y/all years), not per share, so a merger can show up as a growth jump; per-share earnings growth is in the value-creation card. 52/100
The company is growing, but growth may require heavy reinvestment or weak cash conversion.

+2.2%
Revenue growth 3 years ⓘMeasures the company's TOTAL revenue from reported annual statements: compound average growth per year (CAGR) from the fiscal year 3, 5 or N years back to the most recent comparable fiscal year. Not per share: buybacks do not change this number, and a merger can appear as a growth jump. Per-share growth (which does include buybacks) is in the value-creation card.

+29.0%
What shareholders gained per year (last 5 years) ⓘWhat the business itself delivers per year: earnings growth per share plus the dividend yield. This is what you get IF the market keeps valuing the stock the same way: it contains no assumption about the market changing its mind. Computed per share, so buybacks count and a merger does not pass as growth. For a company that pays no dividend it is pure earnings growth per share. Period: earnings growth per share as CAGR over the last 5 reported fiscal years (annual statements), plus the current dividend yield. The start value is the median of the three years around the start, so a single crisis year (a pandemic or a write-down) does not distort the rate.
