Why is Krystal Biotech, Inc. Common Stock (KRYS) stock moving?

KRYS fell 10.9% on Nov 2, from $332.29 to $295.90, on about 1.2M shares, roughly four times the prior sessions' typical volume. The drop came the same day as Q3 2026 results, which showed net product revenue of $127.3M and a new $400M buyback, but also delayed data for KB803, KB801 and KB407 into 2027. Since then the stock has recovered to $306.50 on Nov 10, while volume has eased back to about 196K shares. Analysts kept Buy or Outperform ratings after trimming targets to $375-$412 (RBC, TD Cowen, Citigroup), and some describe the drop as overblown. Company updates also point to near-term items: KB111 interim data before year-end, a Vyjuvek Italy launch in early 2027, and the KB803 topline shortly after last patient visit in Feb 2027. The Galien nomination and conference participation are minor. The main risks are the pipeline slippage, a 2026 non-GAAP R&D and SG&A guide of $155-165M, and net income of $63.1M, below the $79.4M a year earlier.

News behind the analysis

About Krystal Biotech, Inc. Common Stock

Healthcare · Biotechnology (gene therapy)

Krystal Biotech is a Pittsburgh-based biotech company that develops and sells genetic medicines for serious diseases that have few treatment options. What sets it apart is that it is already profitable from one approved product, VYJUVEK, a gene therapy applied to the skin to treat the rare blistering disorder dystrophic epidermolysis bullosa.

How it makes money

Nearly all of its revenue comes from net sales of VYJUVEK, which brought in roughly $127 million in Q3 2026, up from about $116 million in Q1 2026. Gross margins are very high, around 95%. Product sales pay for a pipeline built on the same gene-delivery platform, with programs in cystic fibrosis lung disease, oncology (such as KB707) and other areas. In November 2026 the company also announced a share buyback of about $400 million over two years.
