Item 2.02. Results of Operations and Financial Condition. On August 5, 2026, Emergent BioSolutions Inc. (the "Company") issued a press release (the "Press Release") announcing its financial and operating results for the quarter ended June 30, 2026. A copy of the Press Release is furnished as Exhibit 99.1 to this Current Report on Form 8-K (this "Form 8-K") and is incorporated herein by reference.

Item 2.05. Costs Associated with Exit or Disposal Activities. On August 5, 2026, the Company announced an organizational restructuring plan (the “Restructuring Plan”) intended to strengthen its long-term financial position in response to changes in its business. These strategic actions will lead to a reduction of the Company’s current workforce by approximately 93 employees across all areas of the Company and the elimination of approximately 21 positions that are currently vacant, as well as the closure of wet laboratories in Gaithersburg, Maryland. Decisions regarding the elimination of positions and the closure of wet laboratories are subject to local law and consultation requirements in certain countries, as well as the Company’s business needs. In combination with other rationalizing initiatives, these actions are expected to result in annualized savings of approximately $40 million when fully implemented. The Company estimates that it will incur approximately $10 million to $11.5 million in charges in connection with the Restructuring Plan, which it expects to incur primarily in the second half of 2026. These charges consist primarily of cash charges related to severance (base bonus), transition services, and estimated benefits cost. The estimates of the charges and expenditures that the Company expects to incur in connection with the Restructuring Plan, and the timing thereof, are subject to a number of assumptions, including local law requirements in various jurisdictions, and actual amounts may differ materially from estimates. In addition, the Company may incur other charges or cash expenditures not currently contemplated due to unanticipated events that may occur, including in connection with the implementation of the Restructuring Plan. Expected annualized savings attributable to the Restructuring Plan are also subject to a number of assumptions, and actual amounts may differ materially from estimates.

Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers. In connection with the actions described above, on August 5, 2026 the Company also announced that it will eliminate the role of Chief Medical Officer, Head of Research and Development. As such, Simon Lowry, the Company’s Chief Medical Officer, Head of Research and Development will be leaving the Company effective August 19, 2026. The Company also announced that Stephanie Duatschek, Senior Vice President, Chief Global Strategy & Franchise Development Officer, will assume the role of Executive Vice President, Chief Growth Officer, with responsibility for the Company’s strategic growth. Ms. Duatschek will continue reporting to the Company’s Chief Executive Officer, Joseph Papa.
