Most Popular Narrative: 20.6% Undervalued

Krystal Biotech last closed at $311.50, while the most followed narrative framework places fair value nearer $392.11 using a 7.5% discount rate. That gap reflects a view that the current share price does not fully capture the potential of Vyjuvek and the broader HSV 1 based pipeline.

Advancement of Krystal Biotech toward a multiproduct genetic medicines company through late stage programs such as KB803, KB801, KB407, KB111, KB707 and KB408, supported by HSV 1 platform technology designations, could broaden the revenue base beyond Vyjuvek and spread fixed costs across multiple products.
