Total revenues grew 17 percent to approximately $153 million; fifth consecutive year of profitability

ROCKVILLE, MD, March 22, 2007—Emergent BioSolutions Inc. (NYSE: EBS) announced today that total revenues for 2006 grew 17 percent to $152.7 million from $130.7 million in 2005, driven by the delivery of over 6 million doses of BioThrax® (Anthrax Vaccine Adsorbed) during the year to the U.S. Department of Health and Human Services (HHS) for inclusion in the strategic national stockpile and to the U.S. Department of Defense (DoD) for use in DoD’s active immunization program.

The company also announced today that net income for 2006 was $22.8 million, or $0.99 per share, versus $15.8 million, or $0.77 per share for 2005.

“2006 was a record year for Emergent BioSolutions both in our total revenues and net income and represented our fifth consecutive year of profitability,” said Fuad El-Hibri, chairman and chief executive officer of Emergent BioSolutions. “During the year we also made significant progress in advancing our product development programs, in expanding our manufacturing capacity, and in establishing ourselves as a leader in the biodefense industry. Our mission of protecting lives through the development, manufacturing and commercialization of immunobiotics remains our guiding principle. We look forward to building upon these achievements in 2007.”

Product Sales

For 2006, product sales increased $20.7 million, or 16 percent, to $148.0 million from $127.3 million for 2005, primarily due to an 18 percent increase in the number of doses of BioThrax delivered. Product sales in 2006 consisted of BioThrax sales to HHS of $109.8 million, sales to DoD of $37.4 million and aggregate international and other sales of $0.8 million.

Contracts and Grants Revenue

For 2006, contracts and grants revenue increased by $1.3 million, or 39 percent, to $4.7 million in 2006 from $3.4 million in 2005. Contracts and grant revenues for 2006 consisted of $3.2 million in upfront and development program revenue from the Sanofi Pasteur collaboration and $1.5 million in grant revenue from the Wellcome Trust.

Cost of Product Sales

For 2006, cost of product sales decreased by $7.5 million, or 24 percent, to $24.1 million from $31.6 million for 2005. The decrease was attributable to improved utilization of existing manufacturing capacity for BioThrax, partially offset by an increase of BioThrax doses delivered. Manufacturing efficiencies resulted in a cost savings of approximately $13.1 million. The increase in the number of doses delivered resulted in an increase in costs of approximately $5.6 million.

Research and Development

For 2006, research and development expenses increased by $27.1 million to $45.5 million from $18.4 million for 2005. This increase reflects increased expenses of $11.9 million in the biodefense segment and $15.9 million in the commercial segment, offset by a reduction of $0.6 million in other research and development expense. The biodefense spending was attributable to increased efforts on all biodefense programs related to advancing various studies and trials. The commercial spending was attributable to increased efforts across all five products within the commercial portfolio. The decrease in other research and development expenses was primarily attributable to discontinuation of certain preclinical programs.

Selling, General and Administrative

For 2006, selling, general and administrative expenses increased by $1.8 million, or 4 percent, to $44.6 million from $42.8 million for 2005. SG&A expenses related to the biodefense segment decreased by $0.5 million to $35.0 million for 2006 from $35.5 million for 2005. SG&A expenses related to the commercial segment increased by $2.3 million, or 32 percent, to $9.6 million for 2006 from $7.3 million for 2005. The increase in the commercial segment was primarily attributable to an increase in selling, general and administrative expenses of $1.0 million resulting from the addition of personnel and increased legal and other professional services for the company’s headquarters, and an increase of $0.9 million related to the addition of personnel for the company’s commercial development subsidiary in the UK.

Taxes

For 2006, provision for income taxes increased by $9.9 million to $15.2 million from $5.3 million for 2005. The effective tax rate for 2006 was 40 percent, compared to an effective tax rate of 25 percent for 2005. The increase in the company’s effective annual tax rate resulted primarily from foreign and state net operating losses and an increase in permanent differences, including incentive stock options.

Financial Condition and Liquidity

Cash and cash equivalents at December 31, 2006 was $76.4 million versus $36.3 million at December 31, 2005. The net increase in cash and cash equivalents resulted primarily from the proceeds from the initial public offering and additions to indebtedness, partially offset by capital expenditures and cash used in operations, including research and development expenses.
