Emergent Revises Upward 2010 Financial Forecast

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.”
