ROCKVILLE, MD, July 16, 2010 – Emergent BioSolutions Inc. (NYSE:EBS) today held a ribbon cutting ceremony, led by Governor Martin O’Malley and Fuad El-Hibri, Emergent’s chairman and chief executive officer, to mark the formal opening of Emergent Manufacturing Operations Baltimore.  Emergent’s new facility consists of 56,000 square feet of manufacturing and office space, and includes multiple manufacturing suites designed to support clinical and commercial manufacture of the company’s rPA, anthrax monoclonal, and tuberculosis product candidates, among others.

“The Baltimore facility symbolizes Emergent’s continued investment in manufacturing as one of its core competencies and competitive advantages,” said Mr. El-Hibri.  “It is also a testament to Emergent’s commitment to the State of Maryland, where we are proud to be a key contributor to economic development and job growth.”

“Maryland has a reputation of being a haven for thriving life sciences and biotechnology companies, thanks to industry leaders like Emergent BioSolutions,” said Governor O’Malley. “Emergent’s expansion into Baltimore, through the purchase and re-commissioning of this facility, enables significant investment in the biotech infrastructure already in place and ensures that high-paying, highly-skilled jobs are created and remain in Maryland.”

Emergent employs over 680 employees across the globe, with 180 employees located in Maryland, where, aside from the Baltimore manufacturing facility, its corporate headquarters and one of its product development sites are located.  The opening of this new facility could create an additional 120 jobs in the next five years.

“The opening of this new biopharmaceutical facility is good news for three reasons: jobs, jobs and more jobs for Maryland,” said Senator Barbara Mikulski (MD-D). “To keep our state competitive in the global economy, we have to create and support Maryland’s jobs of the future, like the innovative life sciences jobs at Emergent BioSolutions. I’m proud that East Baltimore has been selected to house a facility dedicated to research that will keep Americans healthy and safe.”

“I’m pleased to welcome Emergent BioSolutions to Baltimore,” said Congressman John Sarbanes (MD-D).  “This manufacturing facility helps Maryland maintain its status as a leader in the bioscience industry and brings more than 100 high paid, high skilled jobs for Marylanders.”

“Baltimore City is excited about Emergent BioSolutions’ decision to invest here, which will create many jobs and contribute a great deal to the Baltimore biotech industry,” Baltimore Mayor Stephanie Rawlings-Blake said.  “I welcome Emergent BioSolutions to Baltimore City and look forward to the company’s growth in one of Baltimore’s key industries.”

The company is currently working on modifying and re-commissioning the facility.  Planned facility modifications will allow for the utilization of disposable manufacturing technology to potentially result in lower capital investments, lower operating costs, and accelerated process development timelines.  The facility previously operated as a Food and Drug Administration (FDA) licensed facility used by an experienced contract manufacturing organization to produce a number of products approved by the FDA and the European Medicines Agency.
