Fair Value models
Bear 67.54 TWDFair Value 103.83 TWDBull 145.21 TWD
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 (0.6241 TWD 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.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.
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.40/100

What shareholders gained per year (last 5 years), in TWD ⓘ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. Measured in TWD: this currency has depreciated against the euro and dollar over the long run, so part of the nominal rate is currency erosion that never reaches a EUR/USD investor.

Growth Forecast
A lot of optimism in the price
The price assumes more growth than the company has delivered so far.
What the price assumes ⓘThis turns our valuation around: instead of asking what the share is worth, it asks what growth the current price requires. It uses the cash the company keeps after all spending (free cash flow), the same discount rate as our models, five years of growth, then slowing evenly to 2 % a year by year ten. Compared with the analysts' sales forecasts extended to the same five years (at least three analysts, for context only, it does not enter the Fair Value): within 3 percentage points counts as "in line" (amber), below that little optimism (green), above that a lot of optimism (red).
