CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q and the documents we incorporate by reference include forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements, other than statements of historical fact, including statements regarding the future performance of Emergent BioSolutions Inc. or any of our businesses, our business strategy, future operations, future financial position, future revenues and earnings, our ability to achieve the objectives of our restructuring initiatives, acquisitions and divestitures, including our future results, projected costs, prospects, plans and objectives of management, are forward-looking statements. We generally identify forward-looking statements by using words like “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “future,” “goal,” “intend,” “may,” “plan,” “position,” “possible,” “potential,” “predict,” “project,” “should,” “target,” “will,” “would,” and similar expressions or variations thereof, or the negative thereof, but these terms are not the exclusive means of identifying such statements. These forward-looking statements are based on our current intentions, beliefs, assumptions and expectations regarding future events based on information that is currently available. You should realize that if underlying assumptions prove inaccurate or unknown risks or uncertainties materialize, actual results could differ materially from our expectations. You are, therefore, cautioned not to place undue reliance on any forward-looking statement contained herein. Any such forward-looking statement speaks only as of the date on which such statement is made and, except as required by law, we do not undertake any obligation to update any forward-looking statement to reflect new information, events or circumstances.

There are a number of important factors that could cause our actual results to differ materially from those indicated by such forward-looking statements, including, among others:

•the availability of U.S. government (“USG”) funding for contracts related to procurement of our medical countermeasures (“MCM”) products, including CYFENDUS®(Anthrax Vaccine Adsorbed (AVA), Adjuvanted), ACAM2000® (Smallpox and Mpox (Vaccinia) Vaccine, Live), CNJ-016® (Vaccinia Immune Globulin Intravenous, Human (VIGIV)), BAT®(Botulism Antitoxin Heptavalent (A,B,C,D,E,F,G)-(Equine)), BioThrax® (Anthrax Vaccine Adsorbed), Ebanga® (ansuvimab-zykl) and/or TEMBEXA®among others, as well as contracts related to development of medical countermeasures;

•our ability to meet our commitments to quality and compliance in all of our manufacturing operations;

•our ability to negotiate additional USG procurement or follow-on contracts for our MCM products that have expired or will be expiring;

•the commercial availability and impact of a generic and branded competition on future sales of NARCAN® (naloxone HCL) Nasal Spray and over-the-counter NARCAN® Nasal Spray and KLOXXADO® Nasal Spray;

•our ability to maintain adequate internal control over financial reporting and to prepare accurate financial statements in a timely manner;

•our ability to maintain sufficient cash flow from our operations to pay our substantial debt, both now and in the future;

•our ability to invest in our business operations as a result of our current indebtedness;

•the impact of our share and debt repurchase programs;

•the procurement of our product candidates by USG entities under regulatory authorities that permit government procurement of certain medical products prior to United States (“U.S.”) Food and Drug Administration (“FDA”) marketing authorization, and corresponding procurement by government entities outside the United States;

•the success of our commercialization, marketing and manufacturing capabilities and strategy;

•our ability to identify and acquire companies, businesses, products or product candidates that satisfy our selection criteria;

•our ability to attract and retain qualified personnel;

•our ability to adequately secure and protect our intellectual property rights;

•the impact of cybersecurity incidents, including the risks from the unauthorized access, interruption, failure or compromise of our information systems or those of our business partners, collaborators or other third parties; and

•the accuracy of our estimates regarding future revenues, expenses, capital requirements and need for additional financing.

The foregoing sets forth many, but not all, of the factors that could cause actual results to differ from our expectations in any forward-looking statement. When evaluating our forward-looking statements, you should consider this cautionary statement along with the sections entitled “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Quantitative and Qualitative Disclosures About Market Risk” in this Quarterly Report on Form 10-Q, as well as the risks identified in our other reports filed with the U.S. Securities and Exchange Commission (the “SEC”). New factors may emerge from time to time, and it is not possible for management to predict all such factors, nor can it assess the impact of any such factor on the business or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement.
