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.

AI conclusion: The pre-revenue biotech shows promise through its BLA submission for exon-51 Duchenne therapy and neuromuscular pipeline but faces challenges from limited durable advantages and ongoing cash burn.
Main risk: High costs and extended timelines of parallel late-stage trials could intensify cash burn and strain resources across the platform.
Dyne just submitted a biologics license application for its exon-51 Duchenne therapy, requesting priority review and targeting a possible launch in early 2027. The company pairs this with ongoing one-year functional data from its myotonic dystrophy program and a pipeline spanning several rare neuromuscular indications. Will the regulatory step accelerate value creation across the platform, or will the costs and timelines of parallel late-stage trials outweigh any near-term gains?
