Fair Value models

Price $30.02 · Upside +121.2%
Model ⓘEach model values the company its own way (discounted cash flow, earnings, assets, dividends). The fair value above starts from their evidence-weighted blend, not from a single model. In cyclical trough or peak years, after dilution or a stock split it is adjusted afterwards, so it can sit above or below the models.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.Coverage ⓘCoverage = 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.24/100

AI conclusion: Record AI demand drives strong 300 mm wafer shipments, yet heavy depreciation from capacity ramps keeps operating profit negative and margins weak.
Main risk: If higher utilization fails to offset depreciation from capacity ramps, the cost structure would continue to weigh on operating margins and keep profits negative.
Sumco sees record shipments of 300 mm wafers as AI data center demand lifts leading-edge logic and memory needs. At the same time heavy depreciation from capacity ramps keeps operating profit negative despite sequential improvement. Will higher utilization finally offset that burden or will the cost structure continue to weigh on margins?
