Repligen Corporation RGEN announced that it has entered into a definitive agreement to acquire Washington-based BioLife Solutions BLFS, a leading developer of bioproduction products and services, for a total value of approximately $1.5 billion, combining cash and stock.
Shares of Repligen were up 2.3%, while BioLife stock was up 6.7% yesterday, following the announcement.
The impending acquisition is expected to strengthen Repligen's position in the fast-growing cell therapy market by adding BioLife's market-leading biopreservation media platform and other cell processing tools.
The deal appears to be a strong strategic fit for Repligen as it is expected to complement the company's existing solutions for cell therapy customers while adding a high-margin consumables business with attractive recurring revenues. The cell therapy market is among the fastest-growing areas of biotechnology, with commercial revenues projected to grow more than 20% annually through the end of the decade.
The transaction is expected to be closed in the fourth quarter of 2026, subject to customary closing conditions.
