Repligen to Acquire BioLife Solutions, Expanding Its Cell Therapy Capabilities with Market Leading Biopreservation Media

Fast-tracks Repligen’s leadership and customer solution offering in high-growth cell therapy market by

adding BioLife’s differentiated, high-margin recurring revenue business

BioLife stockholders to receive cash and Repligen common stock at a value of $31.00 per share, representing a total enterprise value of approximately $1.5 billion

Compelling financially, the transaction is expected to be accretive to Repligen’s top-line growth, adjusted margins, and adjusted earnings per share by at least 5 cents in year one and at least 25 cents in year two

Repligen reports preliminary second quarter reported revenue growth of approximately 12% or 13% organic; BioLife reports preliminary second quarter revenue growth of approximately 21% year-over-year

WALTHAM, Mass. and BOTHELL, Wash., July 22, 2026 — Repligen Corporation (NASDAQ: RGEN, “Repligen,” or “the Company”), a life sciences company focused on bioprocessing technology leadership, and BioLife Solutions, Inc. (NASDAQ: BLFS) (“BioLife”), a leading developer and supplier of cell processing tools and services for the cell and gene therapy (“CGT”) market, today announced they have entered into a definitive agreement under which Repligen, subject to customary closing conditions, will acquire BioLife for a total enterprise value of approximately $1.5 billion, comprised of 64% in Repligen common stock and 36% in cash (the “Transaction”). The directors of each company unanimously approved the Transaction.

Olivier Loeillot, President and Chief Executive Officer of Repligen, said: “The acquisition of BioLife represents a natural next step in the evolution of our strategy and further strengthens our position as a leading provider of mission-critical technologies for biologics manufacturing. BioLife brings a highly differentiated portfolio of products including a market-leading biopreservation media platform and other cell processing tools. This opportunity will expand Repligen’s presence in the rapidly growing cell therapy market, broaden our solutions offering to cell therapy customers, and add a deeply embedded, high-margin consumables business with attractive recurring revenue. Just as important, we believe our shared culture of innovation and customer centricity will create a strong foundation for future growth and value creation.”

“Over the past several years, we have successfully repositioned BioLife around our market-leading biopreservation media franchise, while strengthening our financial profile and establishing a durable foundation for profitable growth,” said Roderick de Greef, Chairman and Chief Executive Officer of BioLife. “Repligen shares our commitment to providing innovative, differentiated, and enabling tools that help customers bring important therapies to patients. Its global commercial reach, complementary technologies and proven operating capabilities make Repligen an ideal partner for BioLife. This Transaction will expand the reach and impact of our portfolio, while providing BioLife stockholders with immediate cash value and the opportunity to participate in Repligen’s future growth.”

Compelling Strategic and Financial Rationale

Cell therapy represents a significant and growing portion of the global pharma pipeline, while commercial revenues are projected to grow at more than 20% annually through the end of the decade. BioLife’s products are deeply embedded in the cell therapy workflow and highly complementary to Repligen’s existing offering in this market. BioLife’s differentiated biopreservation media portfolio, led by CryoStor®, supports 18 commercially approved therapies and the majority of U.S. commercially sponsored cell-based therapy trials. As a combined commercial team, BioLife will benefit from Repligen’s broader global reach, including Asia Pacific, while Repligen will benefit from BioLife’s trusted customer relationships.

The Transaction is expected to be accretive to Repligen’s top-line growth, adjusted margins, and adjusted earnings per share by at least 5 cents in year one and at least 25 cents in year two. Repligen expects at least $20 million of synergies in year one and at least $30 million in year two from eliminating public-company costs, G&A efficiencies, and manufacturing and supply-chain optimization. While this combination is expected to generate important cross-selling opportunities, Repligen’s financial expectations only assume modest revenue synergies leaving the potential for future upside. The cash component of the merger consideration will be funded with cash on hand. Repligen’s balance sheet is expected to remain healthy with greater than $300 million of pro forma cash and cash equivalents, preserving optionality for additional M&A and other investment opportunities.
