The transaction also has a direct positive effect on Investor's financial position." says Börje Ekholm, CEO of Investor

"We believe that Gambro in this stage of its lifecycle will benefit from being privately owned, and that Investor and EQT are well suited to accelerate the development of the group." says Thomas von Koch, Senior Partner at EQT Partners AB
