**Emergent BioSolutions Awarded $30 Million Contract Modification for CYFENDUS® (Anthrax Vaccine Adsorbed, Adjuvanted), a Two-Dose Anthrax Vaccine for Post-Exposure Prophylaxis Use**

GAITHERSBURG, Md., September 2, 2025 (GLOBE NEWSWIRE) -- Emergent BioSolutions Inc. (NYSE: EBS) today announced it has received a $30 million contract modification from the Biomedical Advanced Research and Development Authority (BARDA), part of the Administration for Strategic Preparedness and Response (ASPR) within the U.S. Department of Health and Human Services (HHS), to supply CYFENDUS® (Anthrax Vaccine Adsorbed, Adjuvanted). Deliveries are expected to begin this calendar year and are scheduled to be completed by March 2026.

"This new contract modification is the next step in our ongoing engagement with the U.S. government, with the shared goal to help ensure medical countermeasures, like CYFENDUS® vaccine, are readily available to safeguard civilian populations against the potential threat of anthrax," said Paul Williams, senior vice president, head of products business, global government & public affairs at Emergent. "We're proud to leverage a U.S.-based supply chain for our anthrax vaccines, as we believe this is critical to Emergent's leadership and continued support of the U.S. government's national security priorities."

Anthrax is a Tier 1 biological threat due to its potential to be used for a bioterrorist incident and threat to public health and national security. CYFENDUS® vaccine was approved by the U.S. Food and Drug Administration in July 2023 as a two-dose anthrax vaccine for post-exposure prophylaxis use in individuals 18 through 65 years of age when given with recommended antibacterial drugs.

This follows a previously announced contract modification of $50 million to supply CYFENDUS® (Anthrax Vaccine Adsorbed, Adjuvanted) in December 2024. This project has been supported in whole or in part with federal funds from the U.S. Department of Health and Human Services; Administration for Strategic Preparedness and Response; Biomedical Advanced Research and Development Authority, under contract HHSO100201600030C.

**About CYFENDUS**® **(Anthrax Vaccine Adsorbed, Adjuvanted)**

**Indication**

CYFENDUS® (Anthrax Vaccine Absorbed, Adjuvanted) is a vaccine indicated for post-exposure prophylaxis of anthrax disease following suspected or confirmed exposure to *Bacillus anthracis* in persons 18 through 65 years of age when given with recommended antibacterial drugs. The efficacy of CYFENDUS® vaccine for post-exposure prophylaxis (PEP) is based solely on studies in animal models of inhalational anthrax.

**Important Safety Information**

<u>Contraindication</u>: Do not administer CYFENDUS® to individuals with a history of a severe allergic reaction (e.g., anaphylaxis) following a previous dose of CYFENDUS®,

---

BioThrax® (a licensed anthrax vaccine with the same active ingredient as CYFENDUS®) or any component of the vaccine.

<u>Warnings and Precautions</u>: *Management of Acute Allergic Reactions*: Appropriate medical treatment must be available to manage possible anaphylactic reactions following administration of CYFENDUS®. *Pregnancy*: CYFENDUS® can cause fetal harm when administered to a pregnant individual. In an observational study, there were more birth defects in infants born to individuals vaccinated with BioThrax® (a licensed anthrax vaccine with the same active ingredient as CYFENDUS®) in the first trimester compared to infants born to individuals vaccinated post pregnancy or individuals never vaccinated with BioThrax®.

<u>Adverse Reactions</u>: The most common (≥10%) injection-site adverse reactions reported were tenderness, pain, arm motion limitation, warmth, induration, itching, swelling, and erythema/redness. The most common systemic adverse reactions were muscle aches, tiredness, and headache.
