Steven Gillis, Ph.D., executive chairman of the board of directors and acting president of Trubion, stated, "The acquisition of Trubion by Emergent will accelerate the continued development of our leading products and technologies. We believe the combination of Emergent's strong financial position and expertise in development of biologics with Trubion's innovative SMIP and SCORPION protein therapeutic product candidates and technologies will provide an efficient and effective development path for these promising products and technologies."

Fuad El-Hibri, chairman of the board of directors and chief executive officer of Emergent BioSolutions, stated, "This acquisition strengthens Emergent's biologics capabilities in two key aspects. First, it diversifies our product pipeline beyond infectious diseases into the two high-growth areas of oncology and autoimmunity. And, second, it broadens our monoclonal antibody therapeutic capabilities. Emergent's stable vaccine franchise, substantial capital resources, and expertise in biologics manufacturing and product development combined with Trubion's world-class therapeutic platform technologies and clinical-stage development programs should translate into significant value over the near and long term."

The transaction has been approved by the Board of Directors of both companies and is subject to customary closing conditions, including the approval of the acquisition by stockholders of Trubion, and the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976.
