Item 1.01Entry into a Material Definitive Agreement.

On July 19, 2017, Emergent BioSolutions Inc. entered into an asset purchase agreement with Human Genome Sciences, Inc., a Delaware corporation ("HGS"), GlaxoSmithKline LLC, a Delaware limited liability company ("GSK" and collectively with HGS, the "Seller"), pursuant to which Emergent will acquire certain assets and liabilities of Seller relating to Seller's raxibacumab product for an upfront payment of $76 million and milestone payments of up to $20 million in the aggregate, tied to the achievement of certain product sale and manufacturing-related milestones. Raxibacumab is a monoclonal antibody approved by the Food and Drug Administration for the treatment of adult and pediatric patients with inhalational anthrax in combination with appropriate antibacterial drugs and for prophylaxis of inhalational anthrax when alternative therapies are not available or not appropriate. The product has also been granted orphan drug market exclusivity in the United States until December 2019.

Under the agreement, upon the closing of the transaction, Emergent will (1) acquire, among other assets, raxibacumab, including corresponding product rights, regulatory approvals and intellectual property rights and (2) plan to assume an existing multi-year contract with the Biomedical Advanced Research and Development Authority ("BARDA") for the purchase and delivery of raxibacumab to the Strategic National Stockpile.

The completion of the transaction is subject to certain closing conditions, including (1) expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (2) receipt of consents under certain material contracts and (3) certain other customary conditions. There is no financing condition to the closing of the transaction.

In connection with the closing of the transaction, Emergent will enter into various agreements with Seller or its affiliates, including (1) a pre-novation agreement pursuant to which Seller will subcontract to Emergent the rights and obligations of Seller under the BARDA contract until novation of the contract is effective to Emergent following the closing of the transaction, (2) a technical transfer agreement for up to a four-year term under which Seller will transfer the manufacturing process (bulk and fill/finish) related to raxibacumab to Emergent's facilities in Baltimore, Maryland, (3) a supply agreement under which Seller will manufacture and deliver raxibacumab to BARDA on behalf of Emergent for the duration of certain orders under the BARDA contract, and (4) a transitional services agreement pursuant to which Seller will perform certain services for Emergent for a limited period of time following the closing of the transaction.

The agreement also contains certain termination rights for Emergent and Seller. Upon any termination of the agreement, the agreement will become void and have no effect, except that certain specified obligations of Emergent and Seller shall survive, including their respective obligations concerning confidentiality and public announcements.

The foregoing description of the terms and conditions of the agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the agreement filed herewith as Exhibit 2 and incorporated herein by reference.

A copy of the agreement is attached as an exhibit hereto. It is not intended to provide any other factual information about Emergent or Seller.  In particular, the assertions embodied in the representations and warranties contained in the agreement are qualified by information in the disclosure schedules provided by Seller to Emergent in connection with the signing of the agreement or in filings of the parties with the Securities and Exchange Commission. These confidential disclosure schedules contain information that modifies, qualifies and creates exceptions to the representations and warranties and certain covenants set forth in the agreement. Moreover, certain representations, warranties and covenants in the agreement were used for the purposes of allocating risk between Emergent and the Seller rather than establishing matters of fact or reflecting what investors may view as material. Accordingly, the representations and warranties and covenants in the agreement or any descriptions thereof should not be relied on as a characterization of the actual state of facts about Emergent or Seller or their respective subsidiaries or affiliates. Additionally, the representations, warranties, covenants, conditions and other terms of the agreement may be subject to subsequent waiver or modification. Moreover, information concerning the subject matter of the representations and warranties and covenants in the agreement may change after the date of the agreement, which subsequent information may or may not be fully reflected in Emergent's or the Seller's public disclosures.
