Zentalis has taken a serious beating in 2025 to date, as the market continues to value their pipeline as a liability rather than an asset. The company is in a bit of a holding pattern for now, but possible approval-worthy data are guided for the end of 2026. The market's disinterest in ZNTL creates a substantial, though risky, potential for upside as data gain more anticipation.
