I agree that GE Healthcare is interesting, and a very likely suitor as others have postulated. They are in far more than the prep side though and intend to be a dominant player in cell therapy. They’ve also been on an acquisition and partnership spree as this article and timeline shows:
and note the last sentence ”One should expect more acquisitions and alliances to occur as GE strives to execute its long-term strategy to industrialise Cell Therapy in the same manner as BioManufacturing.”
