GI Partners, a leading private investment firm, announced it has completed the acquisition of the Contract Development and Manufacturing Organization (CDMO) and Cell Solutions businesses from Charles River Laboratories International, Inc., forming Rose BioSolutions ("Rose Bio"), a leading provider of advanced manufacturing capabilities across the cell and gene therapy space.

As an independent company, Rose Bio is purpose-built to deliver end-to-end advanced therapy solutions for clients, providing CDMO's full-service development and manufacturing capabilities across plasmid DNA, viral vector, and cell therapy capabilities, as well as Cell Solutions' ability to deliver the cellular materials that research and advanced therapies depend on.

"Our vision for the launch of Rose Bio was to create an independent company dedicated to cell and gene therapy development and manufacturing, building on the scientific expertise and strong operational track record of the CDMO and Cell Solutions businesses," said Dave Kreter, Managing Director and Head of Healthcare Investments at GI Partners. "Rose Bio fills a gap in the market for a truly end-to-end partner where every step, from starting materials to finished therapy, is part of a single, comprehensive offering. We understand the complexities of the life sciences sector, an industry where we have deep experience, and are well positioned to support the long-term, sustained growth of this platform. We are excited to invest in the infrastructure and world-class team to support the company's consistent execution and accelerate innovation."

"We are grateful to the CDMO and Cell Solutions leadership teams for their ongoing support as we enter this next chapter together as Rose Bio. Their collective efforts have helped create a strong foundation for continued growth, and we are confident the organization is positioned to deliver a seamless transition for customers and teams. We also appreciate the strong support Charles River has provided through this process, and we look forward to maintaining a long-term and mutually beneficial commercial relationship with Charles River," continued Mr. Kreter.
