The clear emerging threat for Krystal Biotech is the potential market entry of a competing gene-corrected cell therapy for dystrophic epidermolysis bullosa (DEB).

• Abeona Therapeutics has submitted a Biologics License Application (BLA) to the FDA for its investigational autologous gene-corrected cell therapy, pz-cel (formerly EB-101), for the treatment of recessive dystrophic epidermolysis bullosa (RDEB). RDEB is a severe form of DEB, which is the primary indication for Krystal Biotech's approved product, Vyjuvek.
• While Vyjuvek is an in vivo topical gene therapy, pz-cel represents an alternative gene-based treatment modality for the underlying genetic defect in RDEB. Abeona's BLA submission, occurring in November 2023, signifies that pz-cel is in advanced regulatory review and could receive approval and launch within 2024, directly competing with Vyjuvek for a significant portion of the DEB patient population.

Krystal Biotech (KRYS) is expected to drive future revenue growth over the next 2-3 years through several key initiatives:

1. Continued Growth and Market Penetration of VYJUVEK in the U.S.: VYJUVEK, Krystal Biotech's FDA-approved gene therapy for Dystrophic Epidermolysis Bullosa (DEB), is a primary revenue generator. The company anticipates sustained growth in U.S. sales as it continues to secure reimbursement approvals and expand patient access. Projections for full-year 2024 anticipate U.S. net product revenues for VYJUVEK to be between $205 million and $220 million, with management reiterating a target of over $1 billion in peak annual sales.

2. International Expansion of VYJUVEK: Krystal Biotech is actively pursuing the international commercialization of VYJUVEK, particularly in Europe and Japan, following successful regulatory approvals. VYJUVEK has already launched in Germany, France, and Japan, with early indications of demand and strong pricing. This geographical expansion is a crucial part of the company's growth strategy to broaden its market reach and capitalize on unmet medical needs in rare diseases globally.

3. Advancement of the Oncology Pipeline, Specifically Inhaled KB707: Krystal Biotech has expanded its R&D pipeline into oncology, with its lead candidate KB707 targeting solid tumor malignancies. The company has prioritized the inhaled formulation of KB707 for non-small cell lung cancer (NSCLC) and expects an End of Phase 2 meeting with the FDA in October 2025 to discuss a potential Phase 3 registration study. This program, which has received Fast Track Designation, leverages the company's HSV-1 platform to deliver genes encoding IL-12 and IL-2 to the tumor microenvironment.

4. Progress in Other Clinical Pipeline Programs: Krystal Biotech is advancing a robust pipeline of investigational genetic medicines in various therapeutic areas. Key programs expected to contribute to future growth include:

   • KB407 for Cystic Fibrosis (CF): Interim data from clinical trials for this inhaled gene therapy are anticipated in Q4 2025.
   • Ophthalmic B-VEC for Ocular Complications of DEB: A Phase 3 study (IOLITE) is underway, with top-line data expected before the end of 2025 and an anticipated launch.
   • KB408 for Alpha-1 Antitrypsin Deficiency (AATD): Clinical trial data for this inhaled gene therapy are also expected in the first half of 2026.
   • Jeune Aesthetics Products: The company's wholly-owned subsidiary, Jeune Aesthetics, is developing products using the same platform for aesthetic skin conditions, showing promise with positive Phase 1 data.

5. Leveraging its Proprietary HSV-1 Gene Delivery Platform: The FDA's platform technology designation for Krystal's HSV-1 viral vector validates its broader utility and potential. This proprietary redosable gene therapy platform allows Krystal Biotech to discover, develop, and commercialize genetic medicines across multiple therapeutic areas, offering a differentiated approach for various rare genetic disorders and potentially unlocking significant new market opportunities beyond its current indications.

Share Issuance

• Krystal Biotech's additional paid-in capital consistently increased, from $0.804 billion in 2021 to $1.127 billion in 2024, and further to $1.146 billion by June 30, 2025.

Capital Expenditures

• Krystal Biotech incurred significant capital expenditures for the construction of its second CGMP facility, ASTRA, acquired in March 2021. The facility began research and development operations in 2023, and the company anticipates continued capital expenditures for ASTRA throughout its operational life.
