Krystal is no longer a pre-revenue story. Fourth-quarter VYJUVEK revenue reached $107.1 million, contributing to $389.1 million in full-year 2025 product sales, with a gross margin at 94%. Net income for the year climbed to $204.8 million, more than double the prior year, while cash and investments ended 2025 at $955.9 million. That balance sheet strength matters in a sector where dilution is common.This fund already runs a concentrated biotech portfolio. Scholar Rock sits near 17% of assets, and Krystal now represents roughly 12%—allocations that very seemingly reflect conviction in commercial-stage rare disease platforms with pipeline depth.Shares are up about 44% over the past year, well ahead of the S&P 500. Yet the valuation case hinges less on momentum and more on durability. VYJUVEK uptake continues globally, and the pipeline spans respiratory, ophthalmology, oncology, and dermatology indications.About the AuthorJonathan Ponciano is a contributing stock market analyst at The Motley Fool.
