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.

The company’s submission provides the U.S. Government with the critical option to select a domestic source to meet planned procurement of 25 million doses of rPA vaccine.

Emergent BioSolutions Inc. (NYSE: EBS) announced today that it has submitted a proposal in response to a request for proposal (RFP) issued by the U.S. Department of Health and Human Services (HHS) for a recombinant protective antigen anthrax vaccine (rPA). Emergent’s rPA vaccine candidate, which has completed one Phase II clinical trial, is a reformulated and more stable form of the rPA 102 vaccine originally developed at USAMRIID and is well positioned to be a leading candidate for an award under this RFP.

This RFP is designed to meet the government’s stated goal to procure 25 million doses of an rPA anthrax vaccine for the Strategic National Stockpile (SNS). This contract would be in addition to the $448 million three-year contract awarded to Emergent in 2007 that includes the supply of 18.75M doses of its FDA licensed anthrax vaccine BioThrax to the SNS. In the event that Emergent receives an award under the rPA RFP, doses of rPA procured by HHS would be in addition to the 18.75 million doses of BioThrax being procured by HHS pursuant to the three-year contract. HHS has indicated that any awards under the rPA RFP would be granted at the end of 2008, at the earliest.

“We are very pleased with our submission in response to this RFP and we are confident that our rPA 102 vaccine is a leading candidate to be selected as an advanced rPA anthrax vaccine. Our company is proud of our proven track record of delivering critical biodefense countermeasures to the U.S. government and we believe our reputation as the premiere domestic biodefense supplier, coupled with our development and manufacturing expertise, uniquely situates Emergent to meet HHS’s stated commitment to procure 25 million doses of a recombinant anthrax vaccine for the Strategic National Stockpile,” said Fuad El-Hibri, chairman and chief executive officer of Emergent BioSolutions.

“Considerable effort and resource have been directed toward improving the stability of the rPA 102 vaccine. Analytical testing as well as animal immunogenicity and efficacy studies indicate the stability of our recombinant protective antigen vaccine candidate has been significantly improved. We are confident that the new, enhanced vaccine formulation will address any stability concerns HHS may have had in the past. The current formulation, we believe, will meet and most likely exceed BARDA stability requirements for an rPA vaccine,” said Dr. James Jackson, senior vice president and chief scientific officer of Emergent BioSolutions.

The company intends to manufacture this rPA anthrax vaccine, as well as BioThrax, in its recently constructed, large-scale manufacturing facility at its Lansing campus. The continued development of this rPA vaccine candidate further solidifies Emergent’s well established franchise of anthrax countermeasures, which now includes:

BioThrax® (Anthrax Vaccine Adsorbed) is the only FDA-approved vaccine to prevent the infection of anthrax. Nearly 2.0 million men and women of the United States military have received the vaccine, and HHS has procured more than 28 million doses of BioThrax for the SNS;

rPA 102, a recombinant anthrax vaccine candidate, which is composed of a purified protein with an alum adjuvant and is designed to induce antibodies that neutralize anthrax toxins;

AVP-21D9, a human monoclonal antibody product candidate being developed as an intravenous post-exposure treatment for patients who present symptoms of anthrax disease; and

AIG, a polyclonal anthrax immune globulin product candidate being developed as an intravenous post-exposure treatment for patients who present symptoms of anthrax disease, is derived from human plasma from individuals who have been vaccinated with BioThrax.

About rPA 102
The vaccine candidate, rPA 102, is based on a recombinant form of the protective antigen protein. This vaccine contains a purified protein (rPA) formulated with an alum adjuvant and is designed to induce antibodies that neutralize anthrax toxins.

Acquisition positions Emergent to offer the U.S. Government a domestic source for an advanced anthrax vaccine candidate to meet planned procurement of 25 million doses of rPA vaccine.

Emergent BioSolutions Inc. (NYSE: EBS) announced today that it has completed the acquisition of all assets and rights related to a recombinant protective antigen (rPA) anthrax vaccine product candidate and related technology from VaxGen, Inc. Recent improvements to the rPA vaccine, specifically related to stability, suggests that it is well positioned to be a leading candidate for an award under a request for proposal (RFP) recently issued by the U.S. Department of Health and Human Services (HHS). The vaccine candidate has completed one Phase 2 clinical study. This RFP is designed to meet the government’s stated goal to procure 25 million doses of an rPA anthrax vaccine for the Strategic National Stockpile (SNS). HHS has indicated that any awards under this RFP are scheduled to be granted in late 2008.

The acquisition of this rPA vaccine candidate, and the pending RFP, have no effect on Emergent’s $448 million contract with HHS for the delivery of 18.75 million doses of BioThrax® (Anthrax Vaccine Adsorbed), the only FDA approved vaccine for the prevention of anthrax disease, into the SNS. Emergent continues to manufacture and deliver doses of BioThrax in accordance with this multi-year agreement.

The company intends to manufacture this new rPA anthrax vaccine, as well as BioThrax, in its recently constructed, large-scale manufacturing facility at its Lansing campus. The acquisition of the rPA vaccine candidate further solidifies Emergent’s well established franchise of anthrax countermeasures, which now includes:

BioThrax®, the only FDA-approved vaccine to prevent the infection of anthrax. Nearly 2.0 million men and women of the United States military have received the vaccine, and HHS has procured more than 28 million doses of BioThrax for the SNS;

rPA 102, a recombinant anthrax vaccine candidate, which is composed of a purified protein with an alum adjuvant and is designed to induce antibodies that neutralize anthrax toxins;

AVP-21D9, a human monoclonal antibody product candidate being developed as an intravenous treatment for patients who present symptoms of anthrax disease; and

AIG, a polyclonal anthrax immune globulin product candidate, which is derived from human plasma from individuals who have been vaccinated with BioThrax.

“As the manufacturer of the only FDA approved anthrax vaccine, Emergent BioSolutions has a proven track record of delivering critical biodefense countermeasures to the U.S. Government. Given HHS’s stated commitment to procure up to an additional 25 million doses of a recombinant anthrax vaccine for the Strategic National Stockpile, we felt this was the right opportunity for our company at the right time,” said Fuad El-Hibri, chairman and chief executive officer of Emergent BioSolutions. “Additionally, we are pleased to provide the U.S. Government with the important option to select an advanced rPA anthrax vaccine candidate from a domestic manufacturer. As the premiere domestic biodefense supplier, this was a natural fit for us,” he continued.

Data reviewed to date relating to the rPA vaccine candidate suggests that the steps taken to address a prior stability issue affecting the vaccine position the product for continued development toward regulatory approval and to be a leading candidate for the HHS procurement contract of 25 million doses under the recently issued RFP.

Under the terms of the asset acquisition, Emergent BioSolutions paid VaxGen $2 million upon execution of the definitive agreement and may be obligated to pay up to an additional $8 million in milestone payments, plus specified percentages of future net sales.

About rPA 102
The vaccine candidate, rPA 102, is based on a recombinant form of the protective antigen protein. This vaccine contains a purified protein (rPA) formulated with an alum adjuvant and is designed to induce antibodies that neutralize anthrax toxins. The vaccine candidate does not cause anthrax infection and is based on the pioneering work of the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID). rPA 102 has been the subject of two research and development grants totaling approximately $100 million from the National Institute for Allergy and Infectious Diseases (NIAID). In 2004, HHS awarded VaxGen an $877 million contract for delivery of 75 million doses of rPA 102. The contract was subsequently terminated by HHS, based on its determination that VaxGen failed to successfully cure the condition endangering performance and failed to meet a milestone imposed by HHS that required VaxGen to initiate a clinical trial of the vaccine candidate by December 18, 2006. This failure was primarily related to stability issues with the vaccine.
