For 1Q 2011, total revenues were $18.5 million as compared to $46.8 million in 2010. In addition, for 1Q 2011 the company recorded a net loss of $21.4 million, or $0.61 per basic share, as compared to net income of $2.5 million, or $0.08 per basic share, in 2010.

R. Don Elsey, chief financial officer of Emergent BioSolutions, stated, “While our first quarter revenues were slightly lower than expected, we remain on track to achieve our full year guidance of total revenues of $320 to $340 million and net income of $35 to $45 million.”

1Q 2011 Key Financial Results

Product Sales

For 1Q 2011, product sales were $5.6 million, a decrease of $33.3 million, or 86 percent, from $38.9 million for 1Q 2010. This decrease was primarily due to an 88 percent decrease in the number of doses of BioThrax delivered. During the first quarter, the company redeployed its potency testing capacity from BioThrax release testing to qualification of replacement reference standards and other development testing. This process, which is required to enable continued future release of BioThrax doses, has now been substantially completed. Product sales revenues for 1Q 2011 consisted of BioThrax sales to CDC of $5.0 million and aggregate international and other sales of $0.6 million.

Contracts and Grants Revenues

For 1Q 2011, contracts and grants revenues were $12.9 million, an increase of $5.0 million, or 63 percent, from $7.9 million for 1Q 2010. The increase was primarily due to revenues from the recently awarded contract from BARDA for large-scale manufacturing for BioThrax, collaborations with Abbott and Pfizer, along with increased activity and associated revenue from development contracts with BARDA and NIAID.

Cost of Product Sales

For 1Q 2011, cost of product sales was $1.1 million, a decrease of $6.4 million, or 86 percent, from $7.5 million for 1Q 2010. This decrease was primarily attributable to the 88 percent decrease in the number of BioThrax doses sold.

Research and Development

For 1Q 2011, research and development expenses were $34.8 million, an increase of $14.8 million, or 74 percent, from $19.9 million for 1Q 2010. This increase primarily reflects higher contract service and personnel costs, and includes increased expenses of $13.9 million on product candidates and technology platform development activities associated with the BioSciences segment and increased expenses of $0.9 million on product candidates associated with the BioDefense segment. Net of development contracts and grants reimbursement revenue along with the net loss attributable to noncontrolling interests, research and development expenses were $20.0 million for 1Q 2011.

Selling, General and Administrative

For 1Q 2011, selling, general and administrative expenses were $18.2 million, an increase of $2.0 million, or 12 percent, from $16.2 million for 1Q 2010. This increase is primarily due to increased personnel-related expenses and professional services to support the business. Selling, general and administrative expenses for 1Q 2011 consisted of $14.0 million associated with the BioDefense segment and $4.2 million associated with the BioSciences segment.

Financial Condition and Liquidity

Cash and cash equivalents combined with investments at March 31, 2011 was $143.3 million compared to $171.0 million at December 31, 2010. Additionally, at March 31, 2011, the accounts receivable balance was $12.0 million, which is comprised primarily of unpaid amounts under our NIAID and BARDA development contracts.

2Q 2011 Revenue Forecast

For the second quarter of 2011, the company anticipates total revenues of $80 to $90 million.

2011 Forecast

For full year 2011, the company is reaffirming its financial forecast of total revenues of $320 to $340 million and net income of $35 to $45 million.

2011 total revenue is expected to be driven by, among other things:

• the continuation of deliveries of BioThrax under the current multi-year procurement contract with CDC, which was recently modified to increase the total contracted doses to 17.9 million;
• additional deliveries of BioThrax under a follow-on, multi-year procurement contract with CDC, anticipated to begin in 4Q 2011;
• a significant increase in contracts and grants revenue based primarily on development contracts related to product development programs in the company’s BioDefense segment; and
• collaboration and milestone revenues associated with achievement of clinical development milestones related to the company’s oncology product candidate, which is under an existing co-development agreement with Abbott, and the company’s autoimmune product candidate, which is being developed by Pfizer under a license agreement from the company.

Emergent’s rPA anthrax vaccine candidate is a purified recombinant protective antigen protein formulated with an alum adjuvant and is designed to induce antibodies that neutralize anthrax toxins.  It is based on the pioneering work of the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) and has been the subject of two research and development grants totaling approximately $100 million by the National Institute of Allergy and Infectious Diseases (NIAID).

ROCKVILLE, Md., Sep 01, 2010 –Emergent BioSolutions Inc. (NYSE:EBS) announced today that it has signed a contract valued at up to $28.7 million with the National Institute of Allergy and Infectious Diseases (NIAID), an institute within the National Institutes of Health (NIH), for advanced development of the company’s third generation anthrax vaccine candidate. The award of this contract increases to over $58 million the total potential development funding from NIAID for this product. This product candidate, one of two third generation vaccines being developed as part of Emergent’s anthrax franchise, consists of BioThrax(R) (Anthrax Vaccine Adsorbed) in combination with a novel immunostimulatory compound, CPG 7909 (VaxImmuneTM).

“Emergent applauds the U.S. government’s commitment to protecting the nation against biological threats by supporting critical development of advanced vaccine and therapeutic candidates,” said Daniel J. Abdun-Nabi, president and chief operating officer of Emergent BioSolutions. “We believe our vaccine candidate addresses key criteria established by the government for a third generation anthrax vaccine. If successfully developed, we believe this product would strengthen the government’s portfolio of biodefense medical countermeasures.”

This four-year development contract consists of a two-year base, valued at $9.1 million, and milestone-based options that if exercised, would increase the total contract value to up to $28.7 million. The base contract will fund activities related to manufacturing and stability studies of Phase II clinical trial lots, process characterization and assay validation, and clinical trial preparation. The milestone-based options include continued stability testing of Phase II clinical trial lots and a clinical study to evaluate safety and immunogenicity of the product candidate. The Phase II clinical trial is anticipated to begin in the first quarter of 2012, with preliminary data expected to be available in the second half of 2012.

This new contract was awarded to expand the development efforts being conducted under a Biomedical Advanced Research and Development Authority (BARDA)/NIAID contract awarded in September 2008, which provides for funding of up to $29.7 million. Thus, with this new contract, the potential funding from the U.S. government for this third generation anthrax vaccine candidate increases to over $58 million.
