Emergent BioSolutions Inc. (NYSE: EBS) today announced the exercise of contract option and modification valued at approximately $20 million to supply BioThrax® (Anthrax Vaccine Adsorbed) to the U.S. Department of Defense (DoD). The first delivery, which was valued at approximately $7 million began in December 2024, and remaining deliveries are expected in 2025.

“We’re pleased to continue our work with the U.S. Department of Defense to supply BioThrax® to protect our nation’s service members who have a high risk of exposure to anthrax,” said Paul Williams, senior vice president, products head at Emergent. “This procurement ensures a continued supply of this important medical countermeasure to the U.S. military and demonstrates our commitment to delivering solutions that address our customers’ needs to prepare for public health threats.”

This option is under Emergent’s existing indefinite-delivery, indefinite-quantity (IDIQ) procurement contract (W911SR24D0001) with the DoD and led by the Joint Program Executive Office for Chemical, Biological, Radiological and Nuclear Defense to supply BioThrax® for use by all branches of the U.S. military as pre-exposure prophylaxis (PrEP) for anthrax disease.

In addition to BioThrax® and CYFENDUS®, Emergent’s anthrax franchise includes two treatments, Anthrasil® [Anthrax Immune Globulin Intravenous (Human)], a polyclonal antibody therapeutic, and raxibacumab, a monoclonal antibody therapeutic.

About BioThrax® (Anthrax Vaccine Adsorbed)
