Most Popular Narrative: 6% Undervalued

Repligen closed at $188.64 compared with a widely followed fair value narrative of $199.70, which frames the recent rally as still leaving some upside on the table based on those assumptions.

Strategic push into fast-growing modalities like cell therapy and ADCs, combined with continued innovation in filtration and PAT-enabled systems, is expected to enhance product mix toward higher-margin offerings and drive gross margin expansion over the next several years. Continued product launches (new resins, Metenova single-use mixers, integrated PAT platforms) and recent acquisitions (e.g., 908 bioprocessing) are building additional recurring consumable pull-through and expanding the addressable market, directly supporting long-term revenue and operating margin growth.
