ROCKVILLE, Md., May 05, 2011 (BUSINESS WIRE) — Emergent BioSolutionsInc. (NYSE: EBS) announced  its financial results for the first quarter ended March 31, 2011.

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.

ROCKVILLE, Md., Jan 25, 2011 (BUSINESS WIRE) — Emergent BioSolutions Inc. (NYSE: EBS) today announced the initiation of a Phase Ib/II study (16201) of TRU-016 for chronic lymphocytic leukemia (CLL). TRU-016 is a CD37-directed Small Modular ImmunoPharmaceutical (SMIP(TM)) protein therapeutic in development for the treatment of B-cell malignancies. TRU-016 is being developed in collaboration with Abbott.

The open-label, multi-center, active-controlled study is expected to enroll up to 114 bendamustine-naïve patients with a confirmed diagnosis of relapsed CLL and who have failed up to three previous treatments. The Phase Ib portion of the study will determine a safe and tolerable dose of TRU-016 in combination with bendamustine in up to 14 patients with relapsed CLL. The primary endpoint for the Phase Ib portion is the incidence of dose-limiting toxicities.

The Phase II portion of the study will evaluate the safety and efficacy of TRU-016 in combination with bendamustine compared with standalone bendamustine treatment in a total of 100 randomized patients. The primary endpoint for the Phase II portion of the study is an overall response rate as defined by 2008 International Workshop on Chronic Lymphocytic Leukemia (IWCLL) criteria. Secondary endpoints include complete and partial response rates as defined by the 1996 National Cancer Institute (NCI) criteria, progression-free survival, duration of response, and improvement in quality of life and disease symptoms.

The pharmacokinetics and pharmacodynamics of TRU-016 will be studied in both phases of the study.

“Given the strong TRU-016 preclinical combination data, and the positive clinical results from the single agent dose escalation study, we believe human clinical evaluation of TRU-016 in combination with bendamustine could yield meaningful results,” said Dr. W. James Jackson, chief scientific officer at Emergent BioSolutions. “The dose escalation study in CLL continues to demonstrate that TRU-016 is well tolerated and clinically active and we look forward to Phase I combination data from this study, as well as the planned Phase I combination study for follicular Non-Hodgkin’s Lymphoma.”

Additional information about this Phase Ib/II clinical study can be found on www.clinicaltrials.gov (protocol 16201).

In December 2010, data were presented at the 52^nd Annual Meeting of the American Society of Hematology (ASH) from a Phase I TRU-016 monotherapy, dose escalation trial involving 57 patients who have had a median of four previous therapies and a median of two prior anti-CD20 therapies. Of the 57 patients, 46% received their last treatment for CLL less than 6 months before entering the study. Genomic data were available for 53 patients, the majority of which (n=35) had high-risk genomic features for CLL, including del(17p) and/or del(11q).

Pharmacokinetic data demonstrated rapid clearance of TRU-016 in the lower dose cohorts. Accumulation was seen in the 3mg/kg TIW and 6mg/kg weekly and higher cohorts. Patients in the 3 mg/kg TIW cohort (n=8) generally maintained serum concentrations of 10 g/ml during treatment. Partial response was observed in seven patients, including two patients with the del(17p) genomic risk factor. The median reduction in absolute lymphocyte count was 73% in those patients with lymphocytosis at baseline. The responses, all partial responses, were observed in patients who had received 1 – 2 prior therapies (n=16) for an overall response rate of 44% (n=7) with a median reduction in lymphocytes of 80% in this population. No responses were observed in patients who had received prior treatment with three or more therapies (n=41), although a median reduction in lymphocytes of 54% was observed in these patients. The median reduction in lymphocytes regardless of baseline lymphocyte count or the number of prior therapies was 60%.

The most commonly reported adverse events were nausea, fatigue, diarrhea, chills, pyrexia, and neutropenia. Serious adverse events occurring in more than one patient were pneumonia, febrile neutropenia, infusion reaction, pyrexia and dyspnea. A maximum tolerated dose has not yet been reached. Additional data from all TRU-016 ASH presentations can be found at: www.truemergent.com.

About CLL

According to the Leukemia & Lymphoma Society, there are approximately 85,710 people in the U.S. living with CLL, and more than 15,000 new cases are diagnosed each year. Existing treatments for CLL have shown significant efficacy in treating indolent B-cell cancers. However, research suggests that many patients do not achieve an initial response and most eventually relapse, which suggests an acute need for differentiated treatments.

About TRU-016

TRU-016 uses a different mechanism of action than currently marketed CD20-directed therapies. As a result, TRU-016 may provide patients with improved therapeutic options and enhance efficacy when used alone or in combination with chemotherapy and/or other CD20-directed therapeutics.

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.”
