Emergent BioSolutions Inc. (NYSE: EBS) announced today that it has closed on its acquisition of Bracco Diagnostics Inc.’s Healthcare Protective Products Division. This acquisition, which includes the RSDL ® (decontamination lotion) product that is cleared for marketing by the U.S. Food and Drug Administration (FDA) for removal or neutralization of chemical warfare agents from the skin, diversifies and broadens Emergent’s biodefense franchise into the chemical countermeasure market. “As a result of this transaction closing, Emergent is focused on the uninterrupted supply of RSDL product to customers and on the seamless integration of the new Healthcare Protective Products Group (HPPG) into our biodefense division,” said Adam Havey, EVP and president of Emergent’s biodefense division. “This news, which comes on the heels of other positive developments in our biodefense division, including receiving BioThrax ® (Anthrax Vaccine Adsorbed) market authorization in Germany as well as reporting positive data from our pivotal study supporting licensure of a post-exposure prophylaxis indication for BioThrax, reinforces Emergent’s leadership position in the biodefense arena.” The Canadian Department of National Defence and the U.S. Department of the Army have both played a central role in the development and licensing of RSDL, which is also cleared for sale by Health Canada, the U.K. Medicines and Healthcare Products Regulatory Agency, and Australia’s Therapeutics Goods Administration. The closing on this acquisition contemplates that certain additional assets will be transferred to the company by year end. The company will discuss the impact of this acquisition to Emergent’s anticipated revenue and net income for full year 2013 during the company’s 2Q 2013 financial results call scheduled for August 5, 2013.
