Company anticipates total revenues of $275 to $300 million and net income of $40 to $50 million

ROCKVILLE, MD, July 20, 2010 – Emergent BioSolutions Inc. (NYSE:EBS) announced today that it is revising upwards its 2010 annual guidance to now reflect anticipated total revenues of $275 to $300 million and net income of $40 to $50 million.  Of the anticipated total revenues of $275 to $300 million, $165 to $190 million is expected to be recognized in the second half of 2010.  This revised forecast does not reflect or incorporate any revenue impact from a possible development contract for the company’s rPA vaccine candidate.

The revision to the 2010 financial forecast is supported primarily by the recent modification to the company’s current BioThrax^® procurement contract with the US Centers for Disease Control and Prevention (CDC).  This contract modification increased the number of doses of BioThrax that the company can deliver into the Strategic National Stockpile (SNS) during calendar 2010.  This increased volume of available doses of BioThrax is due to consistently high production yields throughout 2010.

“This modification by the CDC to our existing BioThrax procurement contract reinforces, yet again, the US government’s commitment to BioThrax as a critical component of the Strategic National Stockpile and to our nation’s defense against bioterrorism,” said Fuad El-Hibri, chairman and chief executive officer of Emergent.  “This is another example of how we continue to work with our US government partners in establishing BioThrax as the backbone of our readiness against the threat of anthrax and to building a stockpile as rapidly as possible.”

Daniel J. Abdun-Nabi, president and chief operating officer of Emergent, also commented, “The production yields we have been experiencing are a direct result of our commitment to driving innovation in our manufacturing process and to a multi-year initiative focused on process optimization of the existing Building 12 production facility.  We are extremely pleased with the results of our continuous process improvement program for BioThrax and expect this program to drive the maintenance of positive production metrics going forward.”

ROCKVILLE, Md., Jul 14, 2010

Emergent BioSolutions Inc. (NYSE:EBS) announced today that it has signed a contract valued at up to $107 million with the Office of the Biomedical Advanced Research and Development Authority (BARDA) of the Department of Health and Human Services (HHS), to develop and obtain regulatory approval for large-scale manufacturing of BioThrax^(R) (Anthrax Vaccine Adsorbed) in Building 55. Building 55 is the company’s large-scale state-of-the-art vaccine manufacturing facility in Lansing, Michigan.

“In line with Emergent’s mission of protecting life, we are proud to be working with HHS to scale-up manufacturing of BioThrax, the only vaccine licensed by the Food and Drug Administration (FDA) for the prevention of anthrax infection,” said Fuad El-Hibri, chairman and chief executive officer of Emergent BioSolutions. “We applaud HHS for its unwavering commitment to strengthen the country’s biodefense infrastructure and to protect our military and civilian populations.”

This cost plus fixed fee development contract has a total value of $107 million and consists of a two-year base period of performance valued at $54.6 million and three option years that, if exercised by BARDA, would increase the contract value to up to $107 million. Under the contract, the company anticipates recognizing revenues of up to $10 million and pretax earnings of up to $5 million during the second half of 2010. A substantial majority of the value of the $107 million contract will be realized in the first three years of performance (July 2010 to July 2013), assuming exercise of the first option year.

The contract award is based on a technical proposal provided to BARDA that projects an annual large-scale manufacturing capacity of 26 million doses in Building 55. This is a significant increase from the company’s current capacity of approximately 7-8 million doses per annum.

The company has developed a comprehensive plan to demonstrate comparability between the current manufacturing process and the large-scale manufacturing process for BioThrax. The contract will fund activities related to process validation, assay validation, fill/finish, and if required, non-clinical and clinical studies. The plan also includes regulatory activities in support of the submission to FDA of a supplemental Biologics License Application (sBLA) for BioThrax at the expanded scale. The company expects to begin manufacturing consistency lots as early as the fourth quarter of 2011.

Emergent has invested significant resources in Building 55, which has been designed to manufacture up to 25 to 30 million doses of BioThrax as currently configured, and is expandable by adding a second manufacturing train that would double annual capacity, based on demand. This is aligned with the company’s core strategy to enhance its manufacturing capabilities to meet the increasing government demand for anthrax vaccines for inclusion in the SNS.

The company also continues to enhance the attractiveness of BioThrax as a significant component of the SNS, most recently through FDA approval of extended shelf life to four years. In addition, based on data from a seven-year study by the Centers for Disease Control and Prevention, the company has submitted to FDA an sBLA to further reduce the BioThrax vaccination schedule to three doses within six months with triennial booster vaccinations. To date, Emergent has supplied over 42 million doses of BioThrax to the U.S. government with additional deliveries scheduled through the third quarter of 2011 pursuant to the current procurement contract with HHS.

Acquisition represents important addition to company’s portfolio of anthrax countermeasures

ROCKVILLE, MD., March 6, 2008—Emergent BioSolutions Inc. (NYSE: EBS) announced that today it completed the acquisition of a group of anthrax monoclonal antibodies from AVANIR Pharmaceuticals (NASDAQ:AVNR), including Avanir’s lead product candidate, AVP-21D9.

AVP-21D9 is a human monoclonal antibody product candidate that is being developed as an intravenous treatment for patients who present with symptoms of anthrax disease following exposure to Bacillus anthracis. In non-clinical studies, this candidate demonstrated an ability to protect animals challenged with a lethal dose of inhaled anthrax spores. AVP-21D9 is being developed with funding support from the National Institute of Allergy and Infectious Diseases of the National Institutes of Health (NIAID), including a grant to establish a cGMP manufacturing process and to test efficacy in additional inhalation studies.

“The acquisition of Avanir’s monoclonal anthrax antibodies rounds out our anthrax countermeasure program nicely. In addition to our FDA-approved product, BioThrax? (Anthrax Vaccine Adsorbed), which is indicated for pre-exposure prevention of anthrax in individuals at high risk of exposure to anthrax spores, we are developing a polyclonal anthrax immune globulin therapeutic, which is a human plasma-derived product candidate. Now, as a result of this acquisition, we have another anthrax therapeutic in our product portfolio – a new monoclonal anthrax antibody product candidate that has performed well in proof-of-concept studies,” said Fuad El-Hibri, chairman and chief executive officer of Emergent BioSolutions. “This transaction reflects our ongoing commitment to develop a full portfolio of countermeasures to strengthen our country’s preparedness in the event of future anthrax attacks.”

The U.S. government is funding the development of, and seeking to procure, two types of treatments for inhalational anthrax disease: polyclonal antibody products, also known as immune globulins, and monoclonal antibody products. Emergent BioSolutions currently is developing a polyclonal anthrax immune globulin (AIG) product, which is being manufactured by Talecris Biotherapeutics, Inc., at its FDA-approved production facilities. Two full-scale lots of this product candidate have been manufactured under current good manufacturing practices at Talecris, and we plan to conduct pivotal human and animal studies in 2008 and 2009, which could position us for a procurement contract as early as next year. NIAID has provided us grant funding of up to $13.4 million for a combination of initiatives relating to our AIG product candidate, including non-clinical efficacy studies and a human safety and pharmacokinetics study.

We intend to pursue additional NIAID development funding for both of our anthrax therapeutic product candidates, and we believe that both therapeutics would be eligible to be procured by the U.S. Department of Health and Human Service for inclusion in the SNS prior to receiving marketing approval, provided that they are deemed to be licensable under Project BioShield.
