Fair Value models
Based on fiscal year 2025 figures (about 8 months old). Earnings retained since then (¥0.3827 per share) are deliberately not added.
Each model values the company its own way; the fair value above is the evidence-weighted blend. Evidence (0 to 100) shows how complete a model's inputs are. How we calculate →
Note: the current price implies far more future growth than the conservative anchors of our models allow (base growth is deliberately capped, we do not regard such extreme rates as sustainable). Our models are not designed for expectations this high; that is why the individual models scatter extremely (¥1.47 to ¥30.65). Read the values as a conservative anchor, not as a price target.
ModelBear ⓘ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

Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.
All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
