Item 8.01 Other Events.

Emergent BioSolutions Inc. (“Emergent”) and Chimerix, Inc. (“Chimerix”) both filed a Premerger Notification and Report Form under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”) on May 26, 2022 with respect to the pending acquisition of Chimerix’s exclusive worldwide rights to brincidofovir, including TEMBEXA® and related assets. On June 27, 2022, Emergent, as the acquiring party, withdrew its May 26, 2022 filing, to provide the government with additional time for review, and intends to resubmit its HSR Act filing on or about June 29, 2022, commencing a new 30-day waiting period under the HSR Act. Following such refiling, the waiting period applicable to the pending transaction will expire at 11:59 p.m., Eastern Time, on or about July 29, 2022. The parties continue to work with the government to conclude the government’s HSR review of the pending transaction as expeditiously as possible.

Separately, Chimerix continues to engage in negotiations with the Biomedical Advanced Research and Development Authority (“BARDA”) regarding a procurement contract (the “BARDA Contract”) for TEMBEXA. Recently, BARDA requested that Chimerix include an additional component to the research and development funding which had a modest impact to the contract and timeline to execution. Chimerix continues to expect that the BARDA Contract will be finalized and initial TEMBEXA product will be shipped to the US Strategic National Stockpile in the second half of 2022. In the meantime, the recently announced international procurement contracts for TEMBEXA are anticipated to provide Chimerix with additional financial flexibility.
