Item 1.01 Entry into a Material Definitive Agreement.

On September 30, 2024, Emergent BioSolutions Inc. (the “Company”) entered into a credit agreement (the “Credit Agreement”) by and among the Company, as borrower, and certain subsidiary borrowers (together with the Company, the “Borrowers”), the lenders from time to time party thereto, and Wells Fargo Bank, National Association, as agent (the “Agent”). The Credit Agreement provides for commitments with respect to revolving loans (the “Revolving Loans”) of up to the lesser of (x) $100 million, which may be increased (but not above $125 million, or the “Maximum Revolver Amount”) or decreased (but not below $50 million) by the Borrowers in accordance with the terms of the Credit Agreement and (y) the Borrowing Base (as defined in the Credit Agreement). Once reduced, the facility may not be increased. Up to $5 million of capacity under the Revolving Loans may be used for swing loans and up to $10 million may be used for the issuance of letters of credit. The Revolving Loans will accrue interest at the Base Rate (as defined in the Credit Agreement) plus a margin of 1.25% (such loans, “Base Rate Loans”) or, at the Company’s election, at a rate equal to Adjusted Term SOFR (as defined in the Credit Agreement and subject to a floor of 0.00%) plus a margin of 2.25% (such loans, “SOFR Loans”), in each case until September 30, 2025. After September 30, 2025, the applicable margin may be reduced to 0.75% in the case of Base Rate Loans, or 1.75% in the case of SOFR Loans, provided the Borrowers’ total leverage ratio is less than 4.00 to 1.00 for the most recently completed fiscal quarter and an event of default is not continuing. A default interest rate of an additional 2.00% per annum would apply on all outstanding obligations that are not paid when due. The Revolving Loans will mature on the first to occur of (i) September 30, 2029; (ii) to the extent there remain outstanding any portion of the term loans extended under that certain credit agreement by and among the Company, the lenders from time to time party thereto, and OHA Agency LLC, as administrative agent (the “Term Loan Agreement”), the date that is 90 days prior to the maturity date under the Term Loan Agreement; and (iii) to the extent any of the Company’s 3.875% Senior Unsecured Notes due 2028 (the “Notes”) remain outstanding, May 17, 2028, which is 90 days prior to the August 15, 2028 maturity date of the Notes. The Credit Agreement contains certain customary default and cross-default provisions (including with respect to defaults under the Term Loan Agreement), representations and warranties and affirmative and negative covenants, including (a) restrictions on prepayments and repurchases of indebtedness, including the Notes, (b) restrictions on dispositions of material intellectual property, (c) a minimum liquidity requirement of $5
