EXPLANATORY NOTE

Emergent BioSolutions Inc. (“Emergent,” the “Company,” “we,” “us,” and “our”) is filing this Amendment No. 1 (this “Amendment") to its Annual Report on Form 10-K for the fiscal year ended December 31, 2022, which was originally filed with the Securities and Exchange Commission (the “SEC”) on March 1, 2023 (the “Original Form 10-K”) to make certain changes as described below.

As part of the Company’s quarterly review process related to the preparation of its unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2023, the Company determined that its net state deferred tax liability was overstated as of December 31, 2022, resulting in an understatement of the income tax benefits reflected on the Company’s consolidated statement of operations. This material error was associated with the use of incorrect state tax rates in the calculation of state deferred tax assets and related valuation allowances, which are non-cash items that resulted in an understatement of the Company's income tax benefit of $11.7 million for the year ended December 31, 2022. Because the correction of this misstatement is material to the previously reported results of operations of the Company included in the Original Form 10-K, the Audit and Finance Committee of the board of directors of the Company (the “Audit Committee”) concluded that the consolidated financial statements included in the Original Form 10-K should no longer be relied upon. In connection with the restatement to correct for this error, the Company determined that it is appropriate to revise the financial statements included in the Amendment to correct other unrelated errors that were either unrecorded or addressed as out-of-period adjustments in previously filed financial statements that were not material, individually or in the aggregate, to those financial statements.

Due to the discovery of this error, Company management re-evaluated the effectiveness of the Company's internal control over financial reporting (“ICFR”) as of December 31, 2022 and identified a material weakness in the Company's ICFR that existed as of December 31, 2022, relating to the calculation and review of the Company’s net state deferred tax liability. The Company’s independent registered public accounting firm, Ernst & Young LLP, has also restated its opinion on the Company’s ICFR as of December 31, 2022 to reflect this material weakness.

Pursuant to this Amendment, the disclosures appearing in the Original Form10-K under the following headings are hereby deleted in their entireties and replaced with the disclosures under the following headings included herein:

•Cautionary Note Regarding Forward-Looking Statements;

•Part I, Item 1A - Risk Factors;

•Part I, Item 2 - Properties;

•Part I, Item 7 - Management’s Discussion and Analysis of Financial Condition and Results of Operations;

•Part II, Item 8 - Financial Statements and Supplementary Data;

•Part II, Item 9A - Controls and Procedures; and

•Part IV, Item 15 - Exhibits and Financial Statement Schedules.

In accordance with Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Company is also including with this Amendment new currently dated certifications of the Company’s Interim Chief Executive Officer and Chief Financial Officer (attached as Exhibits 31.1, 31.2, 32.1, and 32.2). This Amendment also contains a new consent of Ernst & Young LLP attached as Exhibit 23.

Except as described above, this Amendment does not amend, update or change any other items or disclosures in the Original Form 10-K and does not purport to reflect any information or events subsequent to the filing thereof. As such, this Amendment speaks only as of the date the Original Form 10-K was filed, and the Company has not undertaken herein to amend, supplement or update any information contained in the Original Form 10-K to give effect to any subsequent events. Accordingly, this Amendment should be read in conjunction with the Original Form 10-K and any subsequent filings by the Company with the SEC.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Amendment includes 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 our future performance, business strategy, operations, financial position, revenues and earnings, 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. 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 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"), including CYFENDUSTM (Anthrax Vaccine Adsorbed (AVA), Adjuvanted), previously known as AV7909, BioThrax® (Anthrax Vaccine Adsorbed) and ACAM2000® (Smallpox (Vaccinia) Vaccine, Live) among others, as well as contracts related to development of medical countermeasures;

•the availability of government funding for our other commercialized products, including EbangaTM (ansuvimab-zykl), BAT® (Botulism Antitoxin Heptavalent) and RSDL® (Reactive Skin Decontamination Lotion Kit);

•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 acceptance of over-the-counter NARCAN® (naloxone HCl) Nasal Spray;

•the impact of a generic marketplace on NARCAN® (naloxone HCI) Nasal Spray and future NARCAN® sales;

•our ability to perform under our contracts with the USG, including the timing of and specifications relating to deliveries;

•our ability to provide contract development and manufacturing ("CDMO") services for the development and/or manufacture of product and/or product candidates of our customers at required levels and on required timelines;

•the ability of our contractors and suppliers to maintain compliance with current good manufacturing practices and other regulatory obligations;

•our ability to negotiate further commitments related to the collaboration and deployment of capacity toward future commercial manufacturing under our existing CDMO contracts;

•our ability to collect reimbursement for raw materials and payment of service fees from our CDMO customers;

•the results of pending stockholder litigation and government investigations and their potential impact on our business;

•our ability to comply with the operating and financial covenants required by our revolving credit facility (the "Revolving Credit Facility") and our term loan facility (the "Term Loan Facility" and, together with the Revolving Credit Facility, the "Senior Secured Credit Facilities") under a senior secured credit agreement, dated October 15, 2018, between the Company and multiple lending institutions, as amended from time to time, as well as our 3.875% Senior Unsecured Notes due 2028 ("Senior Unsecured Notes");

•our ability to remediate a material weakness in our internal control over financial reporting and to prepare accurate financial statements in a timely manner;

1

•our ability to resolve the going concern qualification in our consolidated financial statements and otherwise successfully manage our liquidity in order to continue as a going concern;

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

•our ability to realize the expected benefits of the sale of our travel health business to Bavarian Nordic;

•the impact of the organizational changes we announced in January 2023 and August 2023;

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

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

•the impact of cyber security 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 needs 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. You should consider this cautionary statement along with the risks identified in Part I, Item 1A, “Risk Factors” of this Amendment and the risk factors identified in our other periodic reports filed with the SEC when evaluating our forward-looking statements. New factors 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.

PART I

ITEM 1A. RISK FACTORS

The following risk factors and other information included in this Amendment should be carefully considered. The occurrence of any of the following risks or of unknown risks and uncertainties may adversely affect our business, operating results and financial condition.

RISK FACTOR SUMMARY

There are a number of government contracting risks that could impact our business, financial condition, operating results and cash flows, including:

•Reduced demand for and/or funding for procurement of CYFENDUS and/or BioThrax vaccines or ACAM2000 and discontinuation of funding of our other USG procurement and development contracts.

•Inability to secure follow-on product procurement contracts with the USG upon the expiration of any of our existing procurement contracts.

There are a number of manufacturing risks that could impact our business, financial condition, operating results and cash flows, including:

•Our inability to maintain quality and manufacturing compliance at our manufacturing facilities for our products and for product candidates for our CDMO customers.

•Disruption at, damage to or destruction of our development and/or manufacturing facilities may impede our ability to manufacture our products, as well as deliver our CDMO services.

•Our operations, including our use of hazardous materials, chemicals, bacteria and viruses expose us to significant potential liabilities.

There are a number of product development and commercialization risks that could impact our business, financial condition, operating results and cash flows, including:

•Clinical trials of product candidates are expensive and time-consuming, and their outcome is uncertain.

•We may fail to capitalize on the most scientifically, clinically or commercially promising or profitable product candidates.

There are a number of regulatory and compliance risks that could impact our business, financial condition, operating results and cash flows, including:

•Failure to comply with complex laws and regulations pertaining to government contracts and resources required for responding to related government inquiries.

•Conditions associated with approvals and ongoing regulation of products may limit how and the extent to which we manufacture and market them.

•Failure to comply with various health care laws could result in substantial penalties.

•Failure to comply with obligations under USG pricing programs may require reimbursement for underpayments and the payment of substantial penalties, sanctions and fines.

•The extent to which we may be able to lawfully offer to sell and sell unapproved products in many jurisdictions may be unclear or ambiguous and such activities may subject us to regulatory enforcement actions.

There are a number of competitive and political risks that could impact our business, financial condition, operating results and cash flows, including:

•Development and commercialization of pharmaceutical products are subject to evolving private and public sector competition.

•NARCAN® Nasal Spray is currently subject to generic and branded competition in the U.S. and may be subject to branded and generic competition in Canada. In addition, the success of NARCAN® Nasal Spray, including in over-the- counter form, is subject to commercial availability of the product and our ability to gain sufficient market acceptance by physicians, patients, third-party payors and others in the medical community

•Biologic products may be affected by the approval and entry of follow-on biologics, or biosimilars in the United States and other jurisdictions.

There are a number of risks related to our intellectual property that could impact our business, financial condition, operating results and cash flows, including:

•Challenges in obtaining or maintaining intellectual property rights and defense or enforcement of such rights, including against current or potential infringers.

3

•Potential discrepancies or challenges with respect to licenses, including our failure to comply with obligations under such licenses.

•Potential loss of proprietary information and know-how, which carries the risk of reducing the value of our technology and products.

•Entry of competing generic drugs upon patent and/or regulatory expires or with patents no longer in force.

There are a number of risks related to reliance on third parties that could impact our business, financial condition, operating results and cash flows, including:

•The loss of sole-source suppliers or an increase in the price of inventory.

•If other parties do not perform as contractually required or as expected, we may not be able to obtain regulatory approval for or commercialize our product candidates.

There are a number of legal and reputational risks that could impact our business, financial condition, operating results and cash flows, including:

•Unfavorable results of legal proceedings and government investigations could adversely impact our business, financial condition and results of operations.

•Our work on public health threats ("PHTs") has exposed us to criticism and may expose us to further criticism, from the media, government personnel and others, which could further harm our reputation, negatively affect our share price, operations and our ability to attract and retain talent.

•Cyber security incidents involving us, our business partners, collaborators or other third parties could harm our ability to operate our business effectively in light of our heightened risk profile.

•We could face product liability exposure associated with the use of our medical products. There can be no assurance that the SAFETY Act, Public Readiness and Emergency Preparedness Act (the "PREP Act"), or other liability protections will be sufficient to limit or avoid product liability, and defending such cases requires significant resources.

There are a number of financial risks that could impact our business, financial condition, operating results and cash flows, including:

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

•Our ability to obtain additional funding and be able to raise capital when needed, including in order to be able to continue as a going concern.

•Our ability to comply with the covenants under our Revolving Credit Facility, Term Loan Facility, Senior Unsecured Notes and any other debt agreements to which we may be a party.

•Our ability to remediate a material weakness in our internal control over financial reporting and to prepare accurate financial statements in a timely manner.

There are a number of risks related to our strategic acquisitions, divestitures and collaborations that could impact our business, financial condition, operating results and cash flows, including:

•We may not be successful in identifying, or structuring or acquiring businesses and products to drive our growth.

•Our failure to successfully integrate acquired businesses and/or assets into our operations and our ability to realize the benefits of such acquisitions.

•Our failure to realize the full benefits from the sale of our travel health business to Bavarian Nordic.

There are a number of risks associated with our common stock, including, but not limited to:

•Our business or our share price could be negatively affected as a result of the actions of stockholders.

•The price of our common stock has been and remains subject to extreme volatility.

The risk factors below contain more detailed descriptions of the risks identified above, as well as additional risks that may materially harm our business, financial condition or results of cash flows.

GOVERNMENT CONTRACTING RISKS

We currently derive a substantial portion of our revenue from USG procurement of the CYFENDUS vaccine and the TEMBEXA, oral antiviral and have historically derived a substantial portion of our revenue from USG procurement of the ACAM2000 vaccine and of BioThrax. If the USG’s demand for and/or funding for procurement of CYFENDUS, BioThrax, ACAM2000 and/or TEMBEXA are substantially reduced, our business, financial condition, operating results and cash flows would be materially harmed.

We derive a substantial portion of our current and expected future revenues from USG procurement of CYFENDUS. As with any approved product, there is a risk that we may encounter challenges causing delays or an inability to deliver CYFENDUS, which may have a material effect on our ability to generate and recognize revenue.

The success of our business and our future operating results are significantly dependent on anticipated funding for the procurement of our anthrax vaccines and the terms of such procurement by the USG, including the price per dose, the number of doses and the timing of deliveries. We have no certainty that funding will be made available for the procurement of our anthrax vaccines. If priorities for the Strategic National Stockpile ("SNS") change generally, or as a result of the conclusion of the USG’s audit of the SNS, or with respect to the level of procurement of our anthrax vaccines, funding to procure future doses of CYFENDUS or BioThrax vaccines may be delayed, limited or not available, The Biomedical Advanced Research Development Authority ("BARDA") may never complete the anticipated full transition to stockpiling CYFENDUS in support of anthrax preparedness, and our future business, financial condition, operating results and cash flows could be materially harmed.

In addition, in the past we have derived a substantial portion of our revenues from sales of ACAM2000 vaccine to the USG. If priorities for the SNS change with respect to ACAM2000 vaccine or the USG decides not to exercise additional options under our ACAM2000 contract, our future business, financial condition, operating results and cash flows could be materially harmed.

Our USG procurement and development contracts require ongoing funding decisions by the USG. Any reduction or discontinuation of funding of any of these contracts could cause our business, financial condition, operating results and cash flows to suffer materially.

The USG is the principal customer for our MCMs and the primary source of funds for the development of most of our product candidates in our development pipeline. We anticipate that the USG will also be a principal customer for any MCMs that we successfully develop from within our existing product development pipeline, as well as those we acquire in the future. Additionally, a significant

portion of our revenue comes from USG development contracts and grants. Over its lifetime, a USG procurement or development program, such as for CYFENDUS under our development and procurement contract with BARDA, may be implemented through the award of many different individual contracts and subcontracts. The funding for such government programs is subject to Congressional appropriations, generally made on a fiscal year basis, even for programs designed to continue for several years. These appropriations can be subject to a number of uncertainties, including political considerations, changes in priorities due to global pandemics, the results of elections and stringent budgetary constraints.

Additionally, our government-funded development contracts typically give the USG the right, exercisable in its sole discretion, to extend these contracts for successive option periods following a base period of performance. The value of the services to be performed during these option periods may constitute the majority of the total value of the underlying contract. Subsequent to the filing of the Original Form 10-K, on July 31, 2023 we were awarded a 10-year contract by BARDA for the advanced development, manufacturing scale-up and procurement of EbangaTM (Ansuvimab-zykl) treatment for Ebola. The contract consists of a base period of performance with two option periods valued at approximately $121 million, and option periods for procurement of EbangaTM over five years valued at up to $583 million. If all option periods are exercised, the total contract value will be valued at up to approximately $704 million. If levels of government expenditures and authorizations for public health countermeasure preparedness decrease or shift to programs in areas where we do not offer products or are not developing product candidates, or if the USG otherwise declines to exercise its options under this contract or our other existing contracts, our revenues would suffer, as well as our business, financial condition, operating results and cash flows.

There can be no assurance that we will be able to secure follow-on product procurement contracts with the USG upon the expiration of any of our existing procurement contracts.

A significant portion of our revenue is substantially dependent upon product procurement contracts with the USG and foreign governments for our MCMs and other commercialized products. Upon the expiration of a procurement contract, we may not be able to negotiate a follow-on procurement contract for the particular product on similar terms. We intend to negotiate follow-on procurement contracts for most of our MCMs and other commercialized products upon the expiration of a related procurement contract, but there can be no assurance that we will be successful obtaining any follow-on contracts. Even if we are successful in negotiating a follow-on procurement contract, it may be for a lower product volume, over a shorter period of performance or be on

5

less favorable pricing or other terms. An inability to secure follow-on procurement contracts for our approved products or product candidates could materially and adversely affect our revenues, and our business, financial condition, operating results and cash flows could be harmed.

The government contracting process is typically a competitive bidding process and involves unique risks and requirements.

Our business involves government contracts and grants, which may be awarded through competitive bidding. Competitive bidding for government contracts presents many risks and requirements, including:

•the possibility that we may be ineligible to respond to a request for proposal;

•the commitment of substantial time and attention of management and key employees to the preparation of bids and proposals;

•the need to accurately estimate the resources and cost structure that will be required to perform any contract that we might be awarded;

•the submission by third parties of protests to our responses to requests for proposal that could result in delays or withdrawals of those requests for proposal; and

•in the event our competitors protest or challenge contract or grant awards made to us through competitive bidding, the potential that we may incur expenses or delays, and that any such protest or challenge could result in the resubmission of bids based on modified specifications, or in the termination, reduction or modification of the awarded contract.

The USG may choose not to award us future contracts for either the development of our new product candidates or for the procurement of our existing MCM and other commercialized products and may instead award such contracts to our competitors. If we are unable to secure particular contracts, we may not be able to operate in the market for products that are provided under those contracts. Additionally, if we are unable to consistently win new contract awards over an extended period, or if we fail to anticipate all of the costs or resources that we will be required to secure and, if applicable, perform under such contract awards, our growth strategy and our business, financial condition and operating results and cash flows could be materially and adversely affected.

The amounts we are paid under our fixed price government procurement contracts are based on estimates we have made of the time, resources and expenses required for us to perform under those contracts. If our

actual costs exceed our estimates, we may not be able to earn an adequate return or may incur a loss under these contracts, which could harm our operating results and materially reduce our net income.

Our current procurement contracts with the U.S. Department of Health & Human Services ("HHS") and the U.S. Department of Defense ("DoD") are generally fixed price contracts. We expect that any future procurement contracts we successfully secure with the USG would likely also be fixed price contracts. Under a fixed price contract, we are required to deliver our products at a fixed price regardless of the actual costs we incur. Estimating costs that are related to performance in accordance with contract specifications is difficult, particularly where the period of performance is over several years, and when factoring in higher levels of inflation. Our failure to anticipate technical problems, estimate costs accurately or control costs during performance of a fixed price contract could reduce the profitability of such a contract or cause a loss, which could harm our operating results and materially reduce our net income.

Unfavorable provisions in government contracts, some of which may be customary, may subject our business to material limitations, restrictions and uncertainties and may have a material adverse impact on our business, financial condition, operating results and cash flows.

Government contracts customarily contain provisions that give the USG substantial rights and remedies, many of which are not typically found in commercial contracts, including provisions that allow the USG to:

•terminate existing contracts, in whole or in part, for any reason;

•unilaterally reduce or modify contracts or subcontracts;

•decline, in whole or in part, to exercise an option to purchase product under a procurement contract or to fund additional development under a development contract;

•decline to renew a procurement contract;

•claim certain rights to facilities or to products, including intellectual property, developed under the contract;

•require repayment of contract funds spent on construction of facilities in the event of contract default;

•take actions that result in a longer development timeline than expected;

•direct the course of a development program in a manner not chosen by the government contractor;

6

•suspend or debar the contractor from doing business with the government or a specific government agency;

•pursue civil or criminal remedies under acts such as the False Claims Act and False Statements Act; and

•control or prohibit the export of products.

Generally, government contracts contain provisions permitting unilateral termination or modification, in whole or in part, at the USG’s convenience. Under general principles of government contracting law, if the USG terminates a contract for convenience, the government contractor may recover only its incurred or committed costs, settlement expenses and profit on work completed prior to the termination. If the USG terminates a contract for default, the government contractor is entitled to recover costs incurred and associated profits on accepted items only and may be liable for excess costs incurred by the government in procuring undelivered items from another source. All of our development and procurement contracts with the USG are terminable at their convenience with these potential consequences.

In addition, our USG contracts grant the USG the right to use technologies developed by us under the government contract or the right to share data related to our technologies, for or on behalf of the USG. Under our USG contracts, we may not be able to limit third parties, including our competitors, from accessing certain of these technology or data rights, including intellectual property, in providing products and services to the USG.

MANUFACTURING RISKS

An inability to maintain manufacturing compliance at our manufacturing facilities, which could adversely affect our business, financial condition, operating results and cash flows.

The FDA conducts periodic inspections of our manufacturing facilities for compliance with current good manufacturing practices ("cGMP") requirements. The Company's failure to maintain compliance with cGMP requirements at our manufacturing facilities has hindered and could continue to hinder our ability to continue manufacturing for our own products and for CDMO customers, which could adversely affect our business, financial condition, operating results and cash flows. For example, in February 2022, the FDA inspected Emergent’s Camden facility and issued an FDA Form 483. In August 2022, the FDA issued a warning letter to Emergent related to the February 2022 inspection. The warning letter included issues pertaining to equipment cleaning and maintenance; aseptic sterilization technique and procedures; and quality systems. In October 2023, the FDA determined that the inspection classification of the Camden facility is "voluntary action indicated" which indicates that, although investigators found and documented objectionable conditions during the inspection, the FDA would not take or recommend

regulatory or enforcement action because the objectionable conditions did not meet the threshold for action at that time. Furthermore, the FDA concluded that the Camden facility inspection was "closed" under 21 CFR 20.64(d)(3) and issued to the Company a "Warning Letter close-out letter".

Any failure to remedy the remaining objectionable conditions at the Camden facility, or any additional failures to maintain compliance with cGMP requirements at any of our manufacturing facilities, could adversely affect our business, financial condition, operating results and cash flows.

Disruption at, damage to or destruction of our manufacturing facilities could impede our ability to manufacture anthrax vaccines, our ACAM2000 vaccine or our other products or product candidates, as well as impact the delivery of CDMO services, which would harm our business, financial condition, operating results and cash flows.

Any interruptions in our manufacturing operations could result in our inability to produce products and product candidates for delivery to satisfy the demands of our customers in a timely manner, which would reduce our revenues and materially harm our business, financial condition, operating results and cash flows. A number of factors could cause interruptions, including:

•equipment malfunctions or failures;

•technology malfunctions;

•cyber-attacks;

•work stoppages or slowdowns;

•civil unrest and protests, including by animal rights activists;

•injunctions;

•damage to or destruction of our manufacturing equipment, or of one or more of our facilities;

•findings and recommendations of health authorities or qualified persons in connection with facility inspections;

•ongoing supply chain interruptions; and

•product contamination or tampering.

The factors listed above could cause disruptions at any of our manufacturing facilities. We do not have any redundant manufacturing facilities for any of our products. Accordingly, any damage to, or disruption or destruction of one or more of our facilities could impede our ability to manufacture our products, and our product candidates and our ability to provide manufacturing and development services for external customers, result in losses and delays, including delays in the performance of our contractual obligations or delays in our clinical trials, any of which could be costly to us and materially harm our

7

business, financial condition, operating results and cash flows.

Providers of MCMs could be subject to an increased risk of terrorist activities. The USG has designated both our Lansing, Michigan and our Bayview bulk manufacturing facility in Baltimore, Maryland as facilities requiring additional security. Although we continually evaluate and update security measures, there can be no assurance that any additional security measures would protect these facilities from terrorist efforts determined to disrupt our manufacturing activities.

Problems may arise during the production of our products and product candidates, as well as those we produce for our CDMO customers, due to the complexity of the processes involved in their development, manufacturing and shipment or other factors. Significant delays in product manufacturing or development and our ability to ramp up production to meet the needs of our customers could cause delays in recognizing revenues, which would harm our business, financial condition, operating results and cash flows.

The majority of our products and product candidates are biologics. Manufacturing biologics, especially in large quantities, is complex. The products must be made consistently and in compliance with a clearly-defined manufacturing process. Problems during manufacturing may arise for a variety of reasons, including problems with raw materials, equipment malfunction and failure to follow specific protocols and procedures. Slight deviations anywhere in the manufacturing process, including obtaining materials, maintaining master seed or cell banks and preventing genetic drift, seed or cell growth, fermentation, contamination including from particulates among other things, filtration, filling, labeling, packaging, storage and shipping, potency and stability issues and other quality control testing, may result in lot failures or manufacturing shut-downs, delays in the release of lots, product recalls, spoilage or regulatory action. Such deviations may require us to revise manufacturing processes or change manufacturers. Additionally, as our equipment ages, it will need to be replaced, which has the potential to result in similar consequences. Success rates can also vary dramatically at different stages of the manufacturing process, which can reduce yields and increase costs. From time to time, we may experience deviations in the manufacturing process that may take significant time and resources to resolve and, if unresolved, may affect manufacturing output and could cause us to fail to satisfy customer orders or contractual commitments, lead to a termination of one or more of our contracts, lead to delays in our clinical trials, result in litigation, or other restrictions on the marketing or manufacturing of a product, any of which could be costly to us, damage our reputation and negatively impact our business. Regulatory action, including the issuance of FDA Form 483 and warning letters can also have an impact.

Additionally, if changes are made to the manufacturing process, we may be required to provide the FDA with pre-clinical and clinical data showing the comparable identity, strength, quality, purity or potency of any impacted products before and after the changes.

We are contractually required to ship our biologic products at a prescribed temperature range and variations from that temperature range could result in loss of product and could significantly and adversely impact our revenues, which would harm our business, financial condition, operating results and cash flows.

In addition, we may not be able to ramp up our manufacturing processes to meet the rapidly changing demand or specifications of our customers on the desired timeframe, if at all. Our inability to ramp up manufacturing to meet the demand or specifications of our customers or the inability to timely obtain regulatory authorization to produce the products or product candidates of our customers could also harm our business, financial condition, operating results and cash flows.

Our products and product candidates procured by the USG and other customers require us to perform tests for and meet certain potency and lot release standards prescribed by the FDA and other agencies, which may not be met on a timely basis or at all.

We are unable to sell any products and product candidates that fail to satisfy certain testing specifications. For example, we must provide the FDA with the results of certain tests, including potency tests, before certain lots are released for sale. Potency testing of each applicable lot is performed against qualified control lots that we maintain. We continually monitor the status of such reference lots for FDA compliance and periodically produce and qualify a new reference lot to replace the existing reference lot. If we are unable to satisfy USG requirements for the release of our products or product candidates, our ability to supply such products and product candidates to authorized buyers would be impaired until such time as we become able to meet such requirements, which could materially harm our future business, financial condition, operating results and cash flows.

Our operations, including our use of hazardous materials, chemicals, bacteria and viruses, require us to comply with regulatory requirements and expose us to significant potential liabilities.

Our operations involve the use of hazardous materials, including chemicals, bacteria and viruses, and may produce dangerous waste products. Accordingly, we, along with the third parties that conduct clinical trials and manufacture our products and product candidates on our behalf, are subject to federal, state, local and foreign laws and regulations that govern the use, manufacture, distribution, storage, handling, exposure, disposal and

8

recordkeeping with respect to these materials. Under the Federal Select Agent Program, pursuant to the Public Health Security and Bioterrorism Preparedness and Response Act, we are required to register with and be inspected by the Centers for Disease Control and Prevention (the "CDC") and the Animal and Plant Health Inspection Service if we have in our possession, or if we use or transfer, select biological agents or toxins that could pose a threat to public health and safety, to animal or plant health or to animal or plant products. This legislation requires stringent safeguards and security measures for these select agents and toxins, including controlled access and the screening of entities and personnel and establishes a comprehensive national database of registered entities. We are also subject to a variety of environmental and occupational health and safety laws. Compliance with current or future laws and regulations in this area can require significant costs and we could be subject to substantial fines and penalties in the event of noncompliance. In addition, the risk of contamination or injury from these materials cannot be completely eliminated. In such event, we could be held liable for substantial civil damages or costs associated with the cleanup of hazardous materials. From time to time, we have been involved in remediation activities and may be so involved in the future. Any related cost or liability might not be fully covered by insurance, could exceed our resources and could have a material adverse effect on our business, financial condition, operating results and cash flows. In addition to complying with environmental and occupational health and safety laws, we must comply with special regulations relating to biosafety administered by the CDC, HHS, U.S. Department of Agriculture and the DoD, as well as regulatory authorities in Canada and Switzerland.

PRODUCT DEVELOPMENT AND COMMERCIALIZATION RISKS

The product candidates that we work on for our CDMO customers may not be safe or effective and even if they are, we may be unable to manufacture sufficient quantities to meet demand.

We provide CDMO services for the development and/or manufacture of various product candidates. There can be no assurance that these product candidates will be safe or effective or that they will be authorized for emergency use or approved by the FDA or any other health regulatory authority. Even if product candidates are found to be safe and/or effective and receive authorization or approval by a health regulatory authority or we receive authorization to produce drug substance or drug product at our facilities, the manufacturing processes for our CDMO programs are complex. There can be no assurance that we will be able to produce sufficient clinical or commercial quantities of any product candidate in a timely basis or at all. Difficulties manufacturing COVID-19 product candidates for certain CDMO customers and the

November 2021 termination of the termination of the Center for Innovation in Advanced Development and Manufacturing agreement with BARDA for COVID-19 vaccine development and manufacturing caused us to suffer considerable reputational and financial damage and resulted in the instigation of stockholder litigation and government investigations described elsewhere in the Original Form 10-K and this Amendment. Further, our announcement in the third quarter of 2023 that we are de-emphasizing focus on our CDMO business may raise concerns regarding our ability to fulfil manufacturing commitments to our CDMO customers. Any future failure to satisfy manufacturing commitments could adversely affect our reputation, subject us to potential legal liability and harm our business, financial condition, operating results and cash flows.

Our growth depends on our success in developing and commercializing our product candidates. If we are unable to commercialize these product candidates or experience significant delays or unanticipated costs in doing so, our business would be materially and adversely affected.

We have invested significant efforts and financial resources in the development of our vaccines, therapeutics and medical device product candidates and the acquisition of additional product candidates. In addition to our product sales, our ability to generate revenue is dependent on a number of factors, including the success of our development programs, the USG's interest in providing development funding for or procuring certain of our product candidates, and the commercial viability of our acquired or developed product candidates. The commercial success of our product candidates can depend on many factors, including accomplishing the following in an economical manner:

•successful development, formulation and cGMP or Quality System Regulation ("QSR") scale-up of manufacturing that meets FDA and/or foreign regulatory requirements;

•successful program partnering;

•successful completion of clinical or non-clinical development;

•receipt of marketing approvals, clearances, or other authorizations from the FDA and equivalent foreign regulatory authorities;

•establishment of commercial manufacturing processes and product supply arrangements;

•training of a commercial sales force for the product;

•successful registration and maintenance of relevant patent and/or other proprietary protection;

9

•competitive pricing and market access; and

•acceptance of the product by potential government and other customers.

In particular, the success of NARCAN® Nasal Spray, including in over-the-counter form, is subject to commercial availability of the product and our ability to gain sufficient market acceptance by physicians, patients, third-party payors and others in the medical community

Clinical trials of product candidates are expensive and time-consuming, and their outcome is uncertain. We must invest substantial amounts of time and financial resources in these trials, which may not yield viable products. Failure to obtain regulatory approval for product candidates, particularly in the United States, could materially and adversely affect our financial resources, which would adversely affect our business, financial condition, operating results and cash flows.

Before obtaining regulatory approval or other authorization of our product candidates, we and our collaborative partners, where applicable, must conduct pre-clinical studies and clinical trials to establish proof of concept and demonstrate the safety and efficacy of our product candidates. Pre-clinical and clinical testing is expensive, difficult to design and implement, can take many years to complete and is uncertain as to outcome. Success in pre-clinical testing and early clinical trials does not ensure that later clinical trials will be successful, and interim results of such trials do not necessarily predict final results. An unexpected result in one or more of our clinical trials can occur at any stage of testing.

We may experience unforeseen events or issues during, or as a result of, pre-clinical testing, clinical trials or animal efficacy studies. These issues and events, which could delay or prevent our ability to receive regulatory approval for a product candidate, include, among others:

•our inability to manufacture sufficient quantities for use in trials;

•the unavailability or variability in the number and types of subjects for each study;

•safety issues or inconclusive or incomplete testing, trial or study results;

•drug immunogenicity;

•lack of efficacy of product candidates during trials;

•government or regulatory restrictions or delays; and

•greater than anticipated costs of trials.

Pre-clinical and clinical testing for certain of our MCM product candidates may face additional difficulties and uncertainties because they cannot ethically or feasibly be tested in human subjects. In the U.S. we expect to rely on the Animal Rule to obtain regulatory approval for some of our MCM product candidates. The Animal Rule permits, for certain limited diseases and circumstances, the use of animal efficacy studies, together with human clinical safety and immunogenicity trials, to support an application for marketing approval. For a product approved under the Animal Rule, certain additional post-marketing requirements apply. For example, to the extent feasible and ethical, applicants must conduct post-marketing clinical studies, such as field studies in the event of an outbreak or act of bioterrorism, to assess the drug's safety and effectiveness. It is possible that results from the animal efficacy studies used to support approval under the Animal Rule may not be predictive of the actual efficacy of our product candidates in humans.

Under the Public Health Service Act (the "PHSA") and the Federal Food, Drug, and Cosmetic Act (the "FDCA"), the Secretary of HHS can contract to purchase MCMs for the SNS prior to FDA approval, clearance, or other authorization of certain MCM product candidates. If the USG does not provide funding for and procure our MCM product candidates, they generally will have to be approved by the FDA through traditional regulatory mechanisms prior to sale and distribution in the United States.

We may fail to select or capitalize on the most scientifically, clinically or commercially promising or profitable product candidates.

We continue to evaluate our product development strategy and, as a result, may modify our strategy in the future. In this regard, we may, from time to time, focus our product development efforts on different product candidates or may delay or halt the development of various product candidates. We may change or refocus our existing product development, commercialization and manufacturing activities based on government funding decisions and other factors. This could require changes in our facilities and our personnel. Any product development changes that we implement may not be successful. In particular, we may fail to select or capitalize on the most scientifically, clinically or commercially promising or profitable product candidates or choose candidates for which government development funds are not available. Our decisions to allocate our R&D, management and financial resources toward particular product candidates or therapeutic areas may not lead to the development of viable commercial products and may divert resources from better business opportunities. Similarly, our decisions to delay or terminate product development programs could also cause us to miss valuable opportunities.

10

REGULATORY AND COMPLIANCE RISKS

There are a number of complex laws and regulations that pertain to government contracts and compliance with those laws and regulations require significant time and cost, which could have a material adverse effect on our business, financial condition, operating results and cash flows.

As a manufacturer and supplier of MCMs and other approved products to the USG addressing PHTs, we must comply with numerous laws and regulations relating to the procurement, formation, administration and performance of government contracts. These laws and regulations govern how we transact business with our government clients and, in some instances, impose additional costs and related obligations on our operations. For a detailed description of the most significant regulations that affect our government contracting business, see the prior discussion under “Regulation - Government Contracting.”

We may be subject to government investigations of compliance with government acquisition regulations. USG agencies routinely audit and investigate government contractors for compliance with applicable laws and standards. Even though we take significant precautions to identify, prevent and deter fraud, misconduct and non-compliance, we face the risk that our personnel or outside partners may engage in misconduct, fraud or improper activities. If we are audited or investigated and such audit or investigation were to uncover improper or illegal activities, we could be subject to civil and criminal fines and penalties, administrative sanctions, including suspension or debarment from government contracting, and suffer significant reputational harm. The loss of our status as an eligible government contractor or significant fines or penalties associated with contract non-compliance or resulting from investigations could have a material adverse effect on our business.

Our long-term success depends, in part, upon our ability to develop, receive regulatory approval for and commercialize product candidates we develop or acquire and, if we are not successful, our business, financial condition, operating results and cash flows may suffer.

Our product candidates and the activities associated with them are subject to extensive FDA regulation and oversight. This includes, but is not limited to, laws and regulations governing product development, product labeling, product testing, manufacturing, storage, product distribution, record keeping, and advertising and promotion. In limited circumstances, governments may have the authority to procure products that have not obtained regulatory approval to stockpile for emergency preparedness and to respond to public health emergencies. In other circumstances, failure to obtain regulatory approval for a product candidate will prevent us from selling and commercializing the product candidate.

In the United States, to obtain authorization from the FDA to market and sell any of our future drug, biologic, or vaccine products, we will be required to submit a New Drug Application (an "NDA") or Biologics License Application (a "BLA") to the FDA. Under the FDCA, the PHSA, and the FDA’s implementation of those statutes, a company must support an NDA or BLA with substantial evidence that the product candidate is effective and evidence that the product is safe. Ordinarily, the FDA requires data from adequate and well-controlled clinical trials, including Phase 3 trials conducted in patients with the disease or condition being targeted, to demonstrate that a drug meets the statutory standards for approval. Once an NDA or BLA is submitted, the FDA has substantial discretion and may refuse to accept our application or may decide that our data are insufficient to support approval and require additional pre-clinical, clinical or other studies. Even if marketing approval of a product candidate is granted, the approval may be subject to limitations on the indicated uses for which the product may be marketed, or to conditions of approval, or contain requirements for costly post-marketing testing and surveillance to monitor the safety or efficacy of the product. Likewise, the data in our device submissions may be insufficient to support approval, de novo classification or clearance where required, and we may not be able to demonstrate to the satisfaction of the FDA that our devices are safe or effective for their intended uses or, for a 510(k) device, that they are substantially equivalent to the predicate. Even if we are granted 510(k) clearances, de novo authorizations, or premarket approval application ("PMA") approvals, they may include significant limitations on the indications for use for the device.

Before we can market a new medical device, or an existing medical device for a new use, or make significant modifications to an existing product, we must first receive either clearance under Section 510(k) of the FDCA, de novo authorization, or approval of a PMA from the FDA, unless an exemption applies. These marketing submissions must also be supported by appropriate data, including in many cases clinical data. Likewise, changes to our combination products, including changes to the device constituent part, may also require a new submission to, and approval from, the FDA.

However, our MCM product candidates may be eligible for approval under the FDA's “Animal Rule,” under which findings from adequate and well controlled animal efficacy studies may serve as the basis of an approval when it is not feasible or ethical to conduct efficacy trials in humans. We cannot guarantee that the FDA will permit us to proceed with approval or licensure of any of our MCM product candidates under the Animal Rule. Even if we are able to proceed under the Animal Rule, product development can take a considerable amount of time, and the FDA may decide that our data are insufficient to support approval and require additional pre-clinical, clinical or other studies, refuse to approve our products,

11

or place restrictions on our ability to commercialize those products. Furthermore, products approved under the Animal Rule are subject to certain additional post-marketing requirements. We cannot guarantee that we will be able to meet this regulatory requirement even if one or more of our product candidates are approved under the Animal Rule.

The process of obtaining these regulatory approvals is expensive, often takes many years if approval is obtained at all, and can vary substantially based upon the type, complexity and novelty of the product candidate involved. Changes in the regulatory approval process may cause delays in the approval or other marketing authorization, or rejection of an application. There is a high rate of failure inherent in the medical product development process, and product candidates that appear promising at early stages of development may fail for a number of reasons, and positive results from pre-clinical studies may not be predictive of similar results in human clinical trials. Similarly, promising results from earlier clinical trials of a product candidate may not be replicated in later clinical trials.

Failure to successfully develop future product candidates may materially adversely affect our business, financial condition, operating results and cash flows.

Unapproved and investigational stage products are also subject to the FDA's laws and regulations governing advertising and promotion, which prohibit the promotion of both unapproved products and unapproved uses of approved products. There is some risk that the FDA could conclude that our communications relating to unapproved products or unapproved uses of approved products constitute the promotion of an unapproved product or product use in violation of FDA laws and regulations. There is also a risk that a regulatory authority in another country could take a similar position under that country's laws and regulations and conclude that we have violated the laws and regulations related to product development, approval, or promotion in that country. If the FDA or any foreign regulatory authority determines that any of our communications constitute pre-approval promotion or promotion of an off-label use, the FDA could request that we modify our promotional materials, issue an untitled letter or warning letter, or subject us to regulatory or enforcement actions, including injunction, seizure, civil fine or criminal penalties.

Even if we or our collaborators obtain marketing approvals for our product candidates, the conditions of approvals and ongoing regulation of our products may limit how we manufacture, market and sell our products, which could materially impair our ability to generate revenue.

Once marketing authorization has been granted, we and our business partners will remain subject to ongoing regulatory oversight of our medical products, including with respect to labeling; safety surveillance and reporting;

registration and listing requirements; cGMP and QSR requirements relating to manufacturing, quality control, quality assurance, and corresponding maintenance of records and documents; advertising and promotional activities; requirements regarding the distribution of samples to physicians and related recordkeeping; and medical device design, development and manufacturing.

The FDA and other agencies, including the U.S. Department of Justice (“DOJ”) and the HHS Office of Inspector General (“OIG”), closely regulate and monitor the marketing and promotion of medical products to ensure that they are marketed in a manner consistent with the FDA-approved label. For drug products, we must promote the product in a manner consistent with the full prescribing information or, for 510(k) cleared devices, consistent with the cleared indication. The FDA, DOJ, and OIG impose stringent restrictions on manufacturers’ communications regarding unapproved/uncleared products and unapproved/uncleared uses of approved/cleared products. If we market unapproved/uncleared products or market our approved/cleared products for unapproved/uncleared indications, we may be subject to enforcement action. Violations of the FDCA and other statutes, including the False Claims Act, relating to the promotion and advertising of prescription products may lead to investigations and enforcement actions alleging violations of federal and state health care fraud and abuse laws, as well as state consumer protection laws.

Certain of our products are subject to post marketing requirements (“PMRs”), which we are required to conduct, and post marketing commitments, which we have agreed to conduct. The FDA has the authority to take action against sponsors who fail to meet the obligations of a PMR, including civil monetary penalties and/or misbranding charges.

In addition, discovery of previously unknown adverse events or other problems with our products, manufacturing partners or manufacturing processes, or failure to comply with regulatory requirements, may result in various penalties and sanctions. For all FDA-regulated products, if the FDA finds that a manufacturer has failed to comply with applicable laws and regulations, or that a product is ineffective or poses an unreasonable health risk, it can institute or seek a wide variety of enforcement actions and other remedies, including but not limited to:

•restrictions on such products, manufacturers or manufacturing processes;

•restrictions on the labeling or marketing of a product;

•restrictions on distribution or use of a product;

•requirements to conduct post-marketing studies or clinical trials;

12

•warning letters or untitled letters;

•refusal to approve pending applications or supplements to approved applications that are submitted;

•delay in or refusal to approve, clear or authorize pending PMA applications, 510(k) premarket submissions, or de novo authorization requests;

•fines, restitution or disgorgement of profits or revenues;

•suspension or withdrawal of marketing approvals;

•refusal to permit the import or export of our products;

•product seizure; and

•injunctions or the imposition of civil or criminal penalties.

If we and our collaborators are not able to comply with post-approval regulatory requirements, we could have the marketing approvals for our products withdrawn by regulatory authorities and our ability to market and sell any products could be limited, which could adversely affect our ability to achieve or sustain profitability. Further, the cost of compliance with post-approval regulations may have a negative effect on our operating results and financial condition.

Any product candidate for which we or our collaborators obtain marketing approval could be subject to restrictions or withdrawal from the market and we may be subject to substantial penalties if we fail to comply with regulatory requirements or if we experience unanticipated problems with our product candidates, when and if any of them are approved.

Likewise, non-compliance with EU requirements regarding safety monitoring or pharmacovigilance, and with requirements related to the development of products for the pediatric population, can also result in significant financial penalties. Similarly, failure to comply with the EU and other legal and regulatory requirements regarding the protection of personal information can also lead to significant penalties and sanctions. Non-compliance with similar requirements in other foreign jurisdictions can also result in enforcement actions and significant penalties.

Current and future legislation may increase the difficulty and cost for us and any collaborators to obtain marketing approval of and commercialize our product candidates and may affect the prices we, or our collaborators, may obtain.

In the United States and foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the health care system

that could prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities and affect our ability to profitably sell any product candidates for which we obtain marketing approval. We expect that current laws, as well as other health care reform measures that may be adopted in the future, may result in more rigorous coverage criteria and additional downward pressure on the price that we, or any collaborators, may receive for any approved products.

The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Affordability Reconciliation Act (collectively, the "ACA"), passed in 2010 and substantially changed the way health care is financed by both governmental and private insurers, and significantly impacted the U.S. biopharmaceutical industry. However, some provisions of the ACA have yet to be fully implemented and certain provisions have been subject to legal and political challenges, as well as efforts by the last Presidential administration to repeal or replace certain aspects of the ACA. On January 28, 2021, however, the President issued an executive order to strengthen implementation of the ACA. Concurrently, Congress considered legislation that would repeal or repeal and replace all or part of the ACA. While Congress has not passed comprehensive repeal legislation, it has enacted laws that modify certain provisions of the ACA, such as removing penalties as of January 1, 2019 for not complying with the ACA’s individual mandate to carry health insurance, delaying the implementation of certain ACA-mandated fees, and increasing the point-of-sale discount that is owed by pharmaceutical manufacturers who participate in Medicare Part D. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Prior to the Supreme Court’s decision, the current Presidential administration issued an executive order initiating a special enrollment period during 2021 for purposes of obtaining health insurance coverage through the ACA marketplace. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare. It is unclear how healthcare reform measures enacted by Congress or implemented by the current Presidential administration or other challenges to the ACA, if any, will impact the ACA or our business.

Additionally, there has been recent heightened federal governmental scrutiny over the manner in which manufacturers set prices for their marketed products. For example, there have been several recent Congressional inquiries and has been proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drug products.

13

Further, the Inflation Reduction Act of 2022 (the “IRA”), was signed into law on August 16, 2022. While the IRA is still subject to rulemaking (with more information to come via guidance documents from the responsible federal agencies), the IRA, as written, will, among other changes, give HHS the ability and authority to directly negotiate with manufacturers the price that Medicare will pay for certain high-priced drugs. The IRA will also require manufacturers of certain Part B and Part D drugs to issue to HHS rebates based on certain calculations and triggers (i.e., when drug prices increase and outpace the rate of inflation). At this time, we cannot predict the implications the IRA provisions will have on our business. These types of laws may have a significant impact on our ability to set a product price we believe is fair and may adversely affect our ability to generate revenue and achieve or maintain profitability.

Additionally, in October 2020, HHS and the FDA published a final rule allowing states and other entities to develop a Section 804 Importation Program ("SIP"), to import certain prescription drugs from Canada into the United States. The final rule is currently the subject of ongoing litigation. At least six states (Vermont, Colorado, Florida, Maine, New Mexico, and New Hampshire) have passed laws allowing for the importation of drugs from Canada, and at least three states (Colorado, Florida, and New Mexico) have submitted SIPs to the FDA for review and approval.

At the state level, individual states are increasingly aggressive in passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. A number of states, for example, require drug manufacturers and other entities in the drug supply chain, including health carriers, pharmacy benefit managers, and wholesale distributors, to disclose information about pricing of pharmaceuticals. In addition, regional health care authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other health care programs. These measures could reduce the ultimate demand for our products, once approved, or put pressure on our product pricing. We expect that additional state and federal health care reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for health care products and services, which could result in reduced demand for our product candidates or additional pricing pressures.

If we fail to comply with foreign, federal, state and local health care laws, including fraud and abuse laws, health

information privacy and security laws, and antitrust laws, we could face substantial penalties and our business, results of operations, financial condition and prospects could be adversely affected.

In the United States, certain of our products are reimbursed under federal and state health care programs such as Medicaid, Medicare, TriCare, and/or state pharmaceutical assistance programs. Many foreign countries have similar laws. Federal and state laws designed to prevent fraud and abuse under these programs prohibit pharmaceutical companies from offering valuable items or services to customers or potential customers to induce them to buy, prescribe, or recommend our product (the so-called “anti-kickback” laws). Exceptions are provided for discounts and certain other arrangements if specified requirements are met. Other federal and state laws, and similar foreign laws, not only prohibit us from submitting any false information to government reimbursement programs but also prohibit us, our employees, or any third party acting on our behalf from doing anything to cause, assist, or encourage our customers to submit false claims for payment to these programs. We are also subject to various federal, state and foreign antitrust and competition laws that prohibit certain activities that may have an impact against potential competitors. Violations of the various fraud and abuse and antitrust laws may result in severe penalties against the responsible employees and us, including jail sentences, large fines, and the exclusion of our products from reimbursement under federal and state programs. Some of the laws that may affect our ability to operate include:

•the federal Anti-Kickback Statute makes it illegal for any person or entity, including a prescription drug manufacturer (or a party acting on its behalf) to knowingly and willfully solicit, receive, offer or pay remuneration, directly or indirectly, overtly or covertly, to induce, or in return for, either the referral of an individual, or the purchase, lease, prescribing or recommendation of an item, good, facility or service reimbursable by a federally funded health care program, such as the Medicare or Medicaid program. The term “remuneration” has been interpreted broadly and may constrain our marketing practices, educational programs, pricing policies and relationships with health care providers or other entities, among other activities;

•the federal False Claims Act imposes criminal and civil penalties, including through civil whistleblower or qui tam actions, against individuals or entities for, among other things,

14

knowingly presenting, or causing to be presented, false or fraudulent claims for payment by a federal health care program or making a false statement or record material to payment of a false claim or avoiding, decreasing or concealing an obligation to pay money to the federal government, with potential liability, including mandatory treble damages and significant per-claim penalties.

•the U.S. federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), which imposes criminal and civil liability for, among other things, knowingly and willfully executing, or attempting to execute, a scheme to defraud any health care benefit program or obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any health care benefit program, regardless of the payor (e.g., public or private) and knowingly and willfully falsifying, concealing or covering up by any trick or device a material fact or making any materially false statement, in connection with the delivery of, or payment for, health care benefits, items or services. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;

•HIPAA, as amended by HITECH, and their respective implementing regulations mandates, among other things, the adoption of uniform standards for the electronic exchange of information in common health care transactions, as well as standards relating to the privacy, security and transmission of individually identifiable health information, which require the adoption of administrative, physical and technical safeguards to protect such information. Among other things, HITECH makes HIPAA's security standards directly applicable to “business associates,” or independent contractors or agents of covered entities that create, receive or obtain protected health information in connection with providing a service for or on behalf of a covered entity;

•the Physician Payments Sunshine Act and its implementing regulations require certain manufacturers of drugs, biologics, medical devices and medical supplies for which payment is available under Medicare, Medicaid or the Centers for Medicare & Medicaid Services (“CMS”) to report certain payments and transfers of value made to U.S. physicians, other healthcare providers and teaching hospitals, and

ownership or investment interests held by physicians, other healthcare providers and their immediate family members; and

•state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws, which may apply to items or services reimbursed by any third-party payor, including commercial insurers; state and foreign laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts; state, local and foreign laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government, obtain pharmaceutical agent licensure, and/or otherwise restrict payments that may be made to health care providers and entities; and state, local and foreign laws that require drug manufacturers to report information related to payments and other transfers of value to health care providers or entities, or marketing expenditures.

Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available under the federal Anti-Kickback Statute, it is possible that some of our business activities could be subject to challenges under one or more of such laws. Moreover, recent health care reform legislation has strengthened these laws. For example, the ACA, among other things, amends the intent requirement of the federal Anti-Kickback Statute and criminal health care fraud statutes, so that a person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it. In addition, the ACA provides that the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act.

If our operations are found to be in violation of any of the laws described above or otherwise, we may be subject to penalties, including civil and criminal penalties, damages, fines, individual imprisonment, integrity obligations, exclusion from funded health care programs and the curtailment or restructuring of our operations. Any such penalties could adversely affect our financial results. We continue to improve our corporate compliance program designed to ensure that our development, marketing, and sales of existing and future products and product candidates are in compliance with all applicable laws and regulations, but we cannot guarantee that this program will protect us from governmental investigations or other

15

actions or lawsuits stemming from a failure to comply with such laws or regulations. If any such actions are instituted against us and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant fines or other sanctions.

Efforts to ensure that our business arrangements with third parties comply with health care laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving fraud and abuse or other health care laws and regulations. If our operations are found to be in violation of any of these laws, we may be subject to significant civil, criminal and administrative penalties, damages, fines, individual imprisonment, integrity obligations, exclusion from government funded health care programs, such as Medicare and Medicaid, and the curtailment or restructuring of our operations. If a third party fails to comply with applicable laws and regulations while acting on our behalf, we may also be subject to criminal, civil, and administrative penalties, including those listed above.

The United States government, state governments and private payors regularly investigate the pricing and competitive practices of pharmaceutical companies and biotechnology companies, and many file actions alleging that inaccurate reporting of prices has improperly inflated reimbursement rates. We may also be subject to investigations related to our pricing practices. Regardless of merit or eventual outcome, these types of investigations and related litigation can result in:

•diversion of management time and attention;

•significant legal fees and payment of damages or penalties;

•limitations on our ability to continue certain operations;

•decreased product demand; and

•injury to our reputation.

Moreover, an adverse outcome, or the imposition of penalties or sanctions for failing to comply with applicable fraud and abuse and antitrust laws, could adversely affect us and may have a material adverse effect on our business, results of operations, financial condition and cash flows.

If we fail to comply with our obligations under U.S. governmental pricing programs, we could be required to reimburse government programs for underpayments and could pay penalties, sanctions and fines.

The issuance of regulations and coverage expansion by various governmental agencies relating to the Medicaid

rebate program will continue to increase our costs and the complexity of compliance and will be time-consuming. Changes to the definition of average manufacturer price ("AMP"), and the Medicaid rebate amount under the ACA, the issuance of final regulations implementing those and other changes has affected and could further affect our 340B “ceiling price” calculations. Because we participate in the Medicaid rebate program, we are required to report average sales price ("ASP"), information to CMS for certain categories of drugs that are paid for under Part B of the Medicare program. Future statutory or regulatory changes or CMS binding guidance could affect the ASP calculations for our products and the resulting Medicare payment rate and could negatively impact our results of operations.

Pricing and rebate calculations vary among products and programs, involve complex calculations and are often subject to interpretation by us, governmental or regulatory agencies and the courts. The Medicaid rebate amount is computed each quarter based on our submission to CMS of our current AMP and “best price” for the quarter. If we become aware that our reporting for a prior quarter was incorrect, or has changed as a result of recalculation of the pricing data, we are obligated to resubmit the corrected data for a period not to exceed twelve quarters from the quarter in which the data originally were due. Any such revisions could have the impact of increasing or decreasing our rebate liability for prior quarters, depending on the direction of the revision. Such restatements and recalculations would increase our costs for complying with the laws and regulations governing the Medicaid rebate program. Price recalculations also may affect the “ceiling price” at which we are required to offer our products to certain covered entities, such as safety-net providers, under the 340B/Public Health Service ("PHS") drug pricing program.

In addition, if we are found to have made a misrepresentation in the reporting of ASP, we are subject to civil monetary penalties for each such price misrepresentation and for each day in which such price misrepresentation was applied. If we are found to have knowingly submitted false AMP or “best price” information to the government, we may be liable for civil monetary penalties per item of false information. Any refusal of a request for information or knowing provision of false information in connection with an AMP survey verification would also subject us to civil monetary penalties. In addition, our failure to submit monthly/quarterly AMP or “best price” information on a timely basis could result in a civil monetary penalty per day for each day the information is late beyond the due date. Such failure could also be grounds for CMS to terminate our Medicaid drug rebate agreement, under which we participate in the Medicaid program. In the event that CMS terminates our rebate agreement, no federal payments would be available under Medicaid or Medicare Part B for our covered outpatient drugs. Governmental agencies may also make changes in

16

program interpretations, requirements or conditions of participation, some of which may have implications for amounts previously estimated or paid. We cannot ensure that our submissions will not be found by CMS to be incomplete or incorrect.

In order for our products to be reimbursed by the primary federal governmental programs, we must report certain pricing data to the USG. Compliance with reporting and other requirements of these federal programs is a pre-condition to: (i) the availability of federal funds to pay for our products under Medicaid and Medicare Part B; and (ii) procurement of our products by the Department of Veterans Affairs ("DVA"), and by covered entities under the 340B/PHS program. The pricing data reported are used as the basis for establishing Federal Supply Schedule ("FSS"), and 340B/PHS program contract pricing and payment and rebate rates under the Medicare Part B and Medicaid programs, respectively. Pharmaceutical companies have been prosecuted under federal and state false claims laws for submitting inaccurate and/or incomplete pricing information to the government that resulted in increased payments made by these programs. Although we maintain and follow strict procedures to ensure the maximum possible integrity for our federal pricing calculations, the process for making the required calculations is complex, involves some subjective judgments and the risk of errors always exists, which creates the potential for exposure under the false claims laws. If we become subject to investigations or other inquiries concerning our compliance with price reporting laws and regulations, and our methodologies for calculating federal prices are found to include flaws or to have been incorrectly applied, we could be required to pay or be subject to additional reimbursements, penalties, sanctions or fines, which could have a material adverse effect on our business, financial condition and results of operations.

To be eligible to have our products paid for with federal funds under the Medicaid and Medicare Part B programs and purchased by certain federal agencies and grantees, we also must participate in the DVA FSS pricing program. To participate, we are required to enter into an FSS contract with the DVA, under which we must make our innovator “covered drugs” available to the “Big Four” federal agencies--the DVA, the DoD, the PHS (including the Indian Health Service), and the Coast Guard--at pricing that is capped under a statutory federal ceiling price ("FCP") formula set forth in Section 603 of the Veterans Health Care Act of 1992 (the "VHCA"). The FCP is based on a weighted average wholesale price known as the Non-Federal Average Manufacturer Price ("Non-FAMP"), which manufacturers are required to report on a quarterly and annual basis to the DVA. Under the VHCA, knowingly providing false information in connection with a Non-FAMP filing can subject us to significant penalties for each item of false information. If we overcharge the government in connection with our FSS contract or Section 703

Agreement, whether due to a misstated FCP or otherwise, we are required to disclose the error and refund the difference to the government. The failure to make necessary disclosures and/or to identify contract overcharges can result in allegations against us under the False Claims Act and other laws and regulations. Unexpected refunds to the government, and responding to a government investigation or enforcement action, can be expensive and time-consuming, and could have a material adverse effect on our business, financial condition, results of operations and growth prospects.

From time to time, we sell unapproved MCMs to government entities under certain circumstances. While this is permissible in some cases, the extent to which we may be able to lawfully offer to sell and sell unapproved products in many jurisdictions may be unclear or ambiguous. Such sales could subject us to regulatory enforcement action, product liability and reputational risk.

Under certain and narrow circumstances, MCMs may be procured by government entities prior to approval by the FDA or other regulatory authorities, a practice which we follow in connection with certain MCMs, including TROBIGARD (and CYFENDUS, prior to its approval by the FDA) in the United States. In the United States, the Secretary of HHS has the authority to contract to purchase MCMs for the SNS prior to FDA approval of the relevant MCM in specified circumstances. The FDA also has the authority to permit the emergency use of medical products that have not yet been approved by the FDA under an EUA. An EUA terminates when the EUA is revoked or the emergency declaration underlying the EUA terminates. An EUA is not a long-term alternative to obtaining FDA approval, licensure, clearance, or other marketing authorization for a product. An EUA has not been granted for TROBIGARD. Absent an applicable exception, our MCM product candidates generally will have to be approved, licensed, or cleared by the FDA or other regulatory authorities in the relevant country through traditional pathways before we can sell those products to governments. Additionally, the laws in certain jurisdictions regarding the ability of government entities to purchase unapproved product candidates can be ambiguous, and the permissibility of exporting unapproved products from the United States and importing them to foreign countries may be unclear in some instances. Nevertheless, government bodies, such as U.S. federal entities other than HHS, state and local governments within the United States, and foreign governments have sought and may further seek to procure our MCM product candidates that are not yet approved. In this situation, we would expect to assess the permissibility and liability implications of supplying our product candidates to such entities on a case-by-case basis, which presents certain challenges, both in the case of U.S. and foreign governments, and particularly under emergency conditions. In addition, agencies or branches of one country’s government may take different positions regarding the permissibility of

17

such sales than another country’s government or even other agencies or branches of the same government. If local enforcement authorities disagree with our conclusion that such activities are permissible, they may take enforcement action against us.

In addition, the sale of unapproved products also could give rise to product liability claims for which we may not be able to obtain adequate indemnification or insurance coverage. For example, despite liability protections applicable to claims arising under U.S. law and resulting from the use of certain unlicensed or unauthorized MCMs, such as a declaration issued under the PREP Act, plaintiffs still may bring lawsuits, alleging among other things, that their claims are not barred under the PREP Act.

In the event that a user of one or more of our products experiences an adverse event, we may be subject to additional reputational risk if the product has not been approved by the FDA or the corresponding regulatory authority of another country, particularly because we will not have approved labeling regarding the safety or efficacy of those products. In addition, legislatures and other governmental bodies that have oversight responsibility for procuring agencies may raise concerns after the fact, even if procurement was permissible at the time, which could result in negative publicity, reputational risk and harm to our business prospects.

There is also a risk that our communications with governments about our unapproved/uncleared products, such as in the procurement context, could be considered promotion of an unapproved/uncleared product or unapproved/uncleared use of an approved product. Therefore, there is a risk that we could be subject to enforcement actions if found to be in violation of such laws or regulations.

Even after regulatory approval is received, if we fail to comply with regulatory requirements, or if we experience unanticipated problems with our approved products, they could be subject to restrictions, penalties or withdrawal from the market.

Any vaccine, therapeutic product or medical device for which we obtain marketing approval, along with the manufacturing processes, post-approval clinical data, labeling, advertising and promotional activities for such product, will be subject to the continual requirements of and review by the FDA and other regulatory bodies. Our approved products are subject to these requirements and ongoing review. For drugs and vaccines, these requirements include submissions of safety and other post-marketing information and reports, plasma donor testing, registration requirements, cGMP, requirements relating to potency and stability, quality control, quality assurance, restrictions on advertising and promotion, import and export restrictions and recordkeeping

requirements. Requirements for medical devices are similar and include QSR compliance, establishment registration and device listing; record keeping; restrictions on advertising and promotion; post-market surveillance, and restrictions on import and export. In addition, various state laws require that companies that manufacture and/or distribute drug products within the state obtain and maintain a manufacturer or distributor license, as appropriate. Some states have similar requirements for devices. Because of the breadth of these laws, it is possible that some of our business activities could be subject to challenge under one or more of such laws.

Government regulators enforce cGMP, QSR, and other requirements through periodic unannounced inspections of manufacturing facilities. The FDA is authorized to inspect domestic and foreign manufacturing facilities without prior notice at reasonable times and in a reasonable manner. Health Canada may conduct similar inspections of our domestic and foreign facilities where products offered and sold in Canada are produced, or related formulation and filling operations are conducted. The FDA, Health Canada, and other foreign regulatory agencies conduct periodic inspections of our facilities. Following several of these inspections, regulatory authorities have issued inspectional observations, some of which were significant, but all of which are being, or have been, addressed through corrective actions. If, in connection with any future inspection, regulatory authorities find that we are not in substantial compliance with all applicable requirements, or if they are not satisfied with the corrective actions we take, our regulators may undertake enforcement action against us, which may include:

•warning letters, untitled letters, and other communications;

•product seizure or withdrawal of the product from the market;

•restrictions on the marketing or manufacturing of a product;

•suspension or withdrawal of regulatory approvals or refusal to approve pending applications or other marketing submissions, or supplements to approved applications;

•fines or disgorgement of profits or revenue; and

•injunctions or the imposition of civil or criminal penalties.

Similar action may be taken against us should we fail to comply with regulatory requirements, or later discover previously unknown problems with our products or manufacturing processes. For instance, our products are tested regularly to determine if they satisfy potency and stability requirements for their required shelf lives. Failure

18

to meet potency, stability or other specification requirements could result in delays in distributions, recalls or other consequences. In November 2022, a specific batch of our RSDL kits was recalled due to leakage, which could cause the product not to perform as effectively as intended. We identified and remediated the cause leading to the November 2022 recall, as well as completed all required actions, notices and report submissions related to the recalled batch. We are currently awaiting formal closure of the recall.

Even if regulatory approval, clearance, or other marketing authorization of a product is granted, the approval, clearance, or marketing authorization may be subject to limitations on the indicated uses for which the product may be marketed or sold or to the conditions of approval. Regulatory approval or other authorization may also contain requirements for costly post-marketing testing and surveillance to monitor the safety or efficacy of the product. If we experience any of these post-approval events, our business, financial condition, operating results and cash flows could be materially and adversely affected.

Additionally, companies may not promote unapproved products or unapproved uses of approved products (i.e. “off-label” uses or uses that are not described in the product’s approved labeling and/or that differ from the uses approved or cleared by the applicable regulatory agencies). A company that is found to have improperly promoted an unapproved/uncleared product or an unapproved/uncleared use of an approved/cleared product may be subject to significant liability, including civil and administrative remedies (such as entering into corporate integrity agreements with the USG), as well as criminal sanctions. If our employees or agents engage in marketing of an unapproved/uncleared product or the unapproved/uncleared use of an approved/cleared product, we could be subject to civil or criminal investigations and monetary and injunctive penalties, which could adversely impact our ability to conduct business in certain markets, negatively affect our business, financial condition, operating results and cash flows, and damage our reputation.

Failure to obtain or maintain regulatory approval in international jurisdictions could prevent us from marketing our products abroad and could limit the growth of our business.

We currently sell certain of our products outside the United States and intend to expand the countries in which we sell our products and have received market authorization under the mutual recognition procedure to sell BioThrax in France, Italy, the Netherlands, Poland, and the United Kingdom. To market or sell our products in foreign jurisdictions under normal circumstances, we generally need to obtain separate regulatory approvals and comply with numerous and varying requirements or

use alternative “emergency use” or other exemptions from general approval and import requirements. Approval by the FDA in the United States or the mutual recognition procedure in the European member states does not ensure approval by all foreign regulatory authorities. The approval procedures in foreign jurisdictions can vary widely and can involve additional clinical trials and data review beyond that required by the FDA or under the mutual recognition procedure. There is also a risk that a regulatory authority in another country could conclude that we have violated the rules and regulations related to product development, approval or promotion in that country. Therefore, there is a risk that we could be subject to a foreign enforcement action if found to be in violation of such laws and regulations. We and our collaborators may not be able to obtain foreign regulatory approvals on a timely basis, if at all, and we may be unable to successfully commercialize our products in desired jurisdictions internationally if no alternate procurement pathway is identified for authorized government customers in a particular jurisdiction. We have limited experience in preparing, filing and prosecuting the applications necessary to gain foreign regulatory approvals and expect to rely on third-party contract research organizations and consultants to assist us in this process. Our reliance on third parties can introduce additional uncertainty into the process.

As of January 1, 2021, the Medicines and Healthcare products Regulatory Agency (the "MHRA"), became responsible for supervising medicines and medical devices in Great Britain, comprising England, Scotland and Wales under domestic law, whereas Northern Ireland continues to be subject to European Union rules under the Northern Ireland Protocol. The MHRA relies on the Human Medicines Regulations 2012 (SI 2012/1916) (as amended) (the "HMR"), as the basis for regulating medicines. The HMR has incorporated into the domestic law of the body of European Union law instruments governing medicinal products that pre-existed prior to the United Kingdom's withdrawal from the European Union. Any delay in obtaining, or an inability to obtain, any marketing approvals, as a result of Brexit or otherwise, may force us to restrict or delay efforts to seek regulatory approval in the United Kingdom for our product candidates, which could significantly and materially harm our business.

Laws and regulations governing international operations may preclude us from developing, manufacturing and selling certain products outside of the United States, require us to develop and implement costly compliance programs, and if violated, can lead to financial and other impacts.

As we continue to expand our commercialization activities outside of the United States, we are subject to an increased risk of violating, and must dedicate additional resources towards avoiding inadvertently

19

conducting activities in a manner that violates, the U.S. Foreign Corrupt Practices Act (the "FCPA"), the U.K. Bribery Act, Canada's Corruption of Foreign Public Officials Act, and other similar foreign anti-bribery laws that prohibit corporations and individuals from corruptly paying, offering to pay, or authorizing the payment of anything of value, directly or indirectly, to any foreign government official, government staff member, political party or party official, or political candidate in an attempt to influence a person working in an official capacity or otherwise obtain an improper advantage. The FCPA also obligates companies whose securities are listed in the United States to comply with certain accounting provisions requiring the Company to maintain books and records that accurately and fairly reflect all transactions of the corporation, including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for international operations. Some anti-bribery laws also apply to private sector bribery. Compliance with the FCPA and other anti-bribery laws is expensive and difficult, particularly in countries in which corruption is a recognized problem. In addition, the FCPA presents particular challenges in the pharmaceutical industry, because, in many countries, hospitals and other parts of the health system are operated by the government, and doctors, hospital employees, and other health care providers are considered foreign officials. Certain payments to hospital employees and other health care professionals in connection with clinical trials and other work have been deemed to be improper payments to government officials and have led to FCPA enforcement actions.

Many countries, including the United States, also have various lobbying laws and regulations governing the conduct of individuals and companies who interact with government officials. These laws and regulations typically include certain restrictions and disclosure obligations. If we, our employees, or third parties acting on our behalf do not comply with these laws and regulations, we may be subject to civil and criminal penalties.

Many countries, including the United States, restrict the export or import of products to or from certain countries through, for example, bans, sanction programs, and boycotts. Such restrictions may preclude us from supplying products in certain countries, which could limit our growth potential. Furthermore, if we, or third parties acting on our behalf, do not comply with these restrictions, we may be subject to civil and criminal penalties.

Various laws, regulations and executive orders also restrict the use and dissemination outside of the United States, or the sharing with certain non-U.S. nationals, of information classified for national security purposes, as well as certain products and technical data relating to those products. If we continue to expand our presence outside of the United States, it will require us to dedicate additional resources to comply with these laws, and these

laws may preclude us from developing, manufacturing, or selling certain products and product candidates outside of the United States, which could limit our growth potential and increase our development costs.

The failure to comply with laws governing international business practices may result in substantial civil and criminal penalties, suspension or debarment from government contracting, and other sanctions, and can cause reputational harm. The SEC also may bring enforcement actions against issuers for violations of the FCPA’s accounting provisions.

COMPETITIVE AND POLITICAL RISKS

Development and commercialization of pharmaceutical products, including for PHT preparedness, are routinely subject to evolving private and public sector competition.

The development and commercialization of new biopharmaceutical and medical technology products is highly competitive and subject to rapid technological advances. We will continue to face future competition from other companies and governments, universities and other non-profit research organizations in respect to our products, any products that we acquire, our current product candidates and any products we may seek to develop or commercialize in the future. The market for products can be subject to development of safer, more effective, more convenient or less costly products. The market for current products can also depend on what resources can be devoted to marketing or selling products, or how companies are positioned to adapt more quickly to new technologies, respond to scientific advances or patient preferences and needs, initiate or withstand substantial price competition and/or procure third-party licensing and collaborative arrangements.

There are a number of companies with products or product candidates addressing PHT preparedness that are competing with us for both USG procurement and development resources. Factors to consider include competitors' financial, technical, marketing and selling resources as well as potential leverage that their intellectual property estates may offer.

Any reduction in demand for our products or reduction or loss of development funding for our products or product candidates in favor of a competing product could lead to a loss of market share for our products and cause reduced revenues, margins and levels of profitability for us, which could adversely affect our business, financial condition, operating results and cash flows.

Our biologic products may face risks of competition from biosimilar manufacturers.

Biological products and product candidates, which we refer to as “Biologic Products,” can be affected by the approval and entry of “biosimilars” in the United States

20

and other jurisdictions. Biosimilar products are licensed through an abbreviated pathway based on a showing that they are “highly similar” to a previously licensed product (known as the reference product) notwithstanding minor differences in clinically inactive components, and there are no clinically meaningful differences from the reference product in terms of safety, purity, and potency. Biologic Products in our current pipeline include CYFENDUS, BioThrax, and ACAM2000. If a biosimilar version of one of our Biologic Products were approved, it could have a material adverse effect on the sales and gross profits of the affected Biologic Product and could adversely affect our business, financial condition, operating results and cash flows.

NARCAN® (naloxone HCl) Nasal Spray is currently subject to generic and branded competition and may be subject to additional generic and branded competition in the future. If demand for OTC NARCAN® Nasal Spray outpaces current estimates, there could be supply challenges to meet demand.

NARCAN® Nasal Spray currently faces generic competition. In 2016, Teva Pharmaceuticals Industries Limited and Teva Pharmaceuticals USA (collectively, "Teva") filed an Abbreviated New Drug Application (an "ANDA") seeking regulatory approval to market a generic version of NARCAN®. In patent litigation related to Teva’s ANDA filing, a trial court decided in favor of Teva, and this decision was subsequently affirmed by the Court of Appeals for the Federal Circuit.

The FDA approved Teva's ANDA on April 19, 2019. On December 22, 2021, Teva commenced the launch of its generic naloxone nasal spray. As part of state settlements, including in Florida, Texas, Rhode Island, and West Virginia, Teva has agreed to supply Medication- Assisted Treatment (MAT) and generic opioid overdose reversal agents, like naloxone, to states at no cost in lieu of additional monetary compensation. The terms of these product donation agreements stretch 10 to 15 years. Currently, the Teva product remains Rx-only but may be switched to OTC, which could provide increased competition for NARCAN® Nasal Spray.

NARCAN® also faces generic competition from Padagis LLC ("Padagis"). Prior to Padagis' separation from Perrigo UK FINCO Limited Partnership ("Perrigo") in 2021, Perrigo filed its own ANDA for generic naloxone nasal spray in 2018. Emergent settled with Perrigo on February 12, 2020 providing for a license effective upon the Teva litigation decision. In June 2022, the FDA approved the ANDA and Padagis launched its prescription generic naloxone nasal spray. On July 18, 2023, the FDA approved an Rx-to-OTC switch of Padagis’ product. In March 2023, Amneal Pharmaceuticals, Inc. announced that the FDA had accepted for review Amneal’s ANDA for generic naloxone nasal spray.

Sales of generic versions of NARCAN® at prices lower than our branded product or provided at no cost by Teva, Padagis and Amneal (pending approval) have the potential to erode our sales and could impact our product revenue related to NARCAN.

NARCAN® Nasal Spray also faces branded competition from RiViveTM (naloxone HCl nasal spray 3mg), a branded product developed by Harm Reduction Therapeutics; Kloxxado™, (naloxone HCI nasal spray 8mg), a branded product developed by Hikma Pharmaceuticals, Inc., Amphastar Pharmaceuticals, Inc.'s naloxone injection product, Teleflex Medical Inc.'s Intranasal Mucosal Atomization Device and Zimhi™ (naloxone), a branded injectable product developed by Adamis Pharmaceuticals Corporation.

NARCAN® may also face additional generic and branded competition in the future.

Political or social factors may delay or impair our ability to market and sell our products and may require us to spend significant management time and financial resources to address these issues.

Products developed to counter the potential impact of PHTs are subject to changing political and social environments. The political responses and social awareness of the risks of these threats on military personnel or civilians and the level of emphasis placed on such risks by the USG may vary over time. If the threat of terrorism were to decline, then the public perception of the risk on public health and safety may be reduced. This perception, as well as political or social pressures (including as a result of negative publicity we have received based on our longstanding ties to the USG), could delay or cause resistance to bringing our products in development to market or limit pricing or purchases of our products, any of which could negatively affect our revenues and our business, financial condition, operating results and cash flows.

In addition, substantial delays or cancellations of purchases could result from protests or challenges from third parties. Lawsuits brought against us by third parties or activists, even if not successful, could require us to spend significant management time and financial resources defending the related litigation and could potentially damage the public's perception of us and our products. Any publicity campaigns or other negative publicity may adversely affect the degree of market acceptance of our MCMs and thereby limit the demand for our products, which would adversely affect our business, financial condition, operating results and cash flows.

We may not be able to obtain orphan drug exclusivity for product candidates we may develop, and even if we do, that exclusivity may not prevent the FDA or foreign regulatory authorities from approving other competing products.

21

Under the Orphan Drug Act, the FDA may designate a product as an orphan drug if it is a drug or biologic intended to treat a rare disease or condition. Generally, if a product candidate with an orphan drug designation subsequently receives the first marketing approval for the indication for which it has such designation, the product is entitled to a period of marketing exclusivity, which precludes the FDA from approving another marketing application for the same drug for the same rare disease or condition for that time period. The applicable period is seven years in the United States.

In order for the FDA to grant orphan drug designation to one of our products, the agency must find, among other requirements, that the product is being or will be investigated for a condition or disease with a patient population of fewer than 200,000 individuals in the United States, or, for a vaccine, diagnostic drug, or preventive drug, it will be administered to fewer than 200,000 persons per year in the United States. Alternatively, the FDA may determine that there is no reasonable expectation that the costs of research and development of the drug can be recovered from sales of the drug in the United States. The FDA may conclude that the condition or disease for which we seek orphan drug designation does not meet this standard. Even if we obtain orphan drug exclusivity for a product, that exclusivity may not effectively protect the product from competition because different products can be approved for the same condition. In addition, even after a product receives orphan drug exclusivity, the FDA can subsequently approve the same product for the same condition if the FDA or such authorities conclude that the later product is clinically superior in that it is shown to be safer, more effective or makes a major contribution to patient care; if the FDA determines that the holder of orphan drug exclusivity cannot ensure the availability of sufficient quantities of the product to meet the needs of patients with the rare disease or condition; or if the holder of orphan drug exclusivity consents to the approval of such subsequent product. Additionally, the FDA may revoke orphan drug designation if the FDA determines that the request for designation contained an untrue statement of material fact, omitted material information, or the FDA subsequently finds that the drug in fact had not been eligible for orphan drug designation at the time of submission of the request for designation.

We face similar risks in the EU and other foreign jurisdictions that have comparable regulations concerning orphan drug exclusivity.

INTELLECTUAL PROPERTY RISKS

Protection of our intellectual property rights is an important tool for sustaining our business and the failure to do so could impact our financial condition, operating results, and cash flows.

We actively seek to protect intellectual property rights related to our Company's assets, including patent rights, trademark rights, trade secrets and proprietary confidential information, through defense and enforcement of existing rights and pursuit of protection on new and arising innovations.

Obtaining, maintaining and defending our intellectual property rights in the United States and other countries remains a critical component of the development and commercialization of our Company's assets.

Some of the risks associated with procurement, maintenance and enforcement of intellectual property rights include changes in patent laws or administrative patent office rules, evolving criteria and eligibility of obtaining patent protection on particular subject matter, the validity and enforceability of our intellectual property rights, the potential scope of coverage of our intellectual property rights, and/or the availability or strength of legal remedies in a particular country to defend and enforce intellectual property rights.

Other risks include associated costs, such as costs of patent prosecution and maintenance and costs associated with post-grant challenges. For example, such costs include inter partes review proceedings in the United States and oppositions in Europe, as well as costs associated with litigating and enforcing patent and trademark rights.

Additional risks include limitations on our extent or ability to procure, maintain or defend intellectual property rights associated with in-licensed or acquired intellectual property, where, for example, other parties (e.g., licensors) may have the first right to maintain or defend intellectual property rights in which we have an interest, or may pursue strategies that are divergent to the interest of our Company.

Third party claims of for patent infringement could impact our business, financial condition, operating results, and cash flows.

Claims by other parties of alleged patent infringement could delay, stop or affect the development and commercialization of our products and product candidates. Such challenges, while ongoing, could be costly, requiring and utilizing company resources. Such challenges, if successful, may impact marketing or launch of products, or require ongoing license and/or royalty fees associated with potential settlement agreements. These challenges may have the potential to materially harm our business, financial condition, operating results, and cash flows.

Intellectual property licenses with third parties carry risks of challenges, which may be costly and time consuming and could impact the commercialization of our products.

We are a party to a number of license agreements and expect to enter into additional license agreements in the future. Such license agreements or collaboration arrangements can be subject to challenges if interests or expectations under such license agreements diverge. Such challenges may be costly, risk time and resources, and could delay or impact development, commercialization or launch of our products.

Potential loss of proprietary information and know-how generally carries the risk of reducing the value of our technology and products.

We also rely upon unpatented proprietary technology, processes, and know-how, particularly as to our proprietary manufacturing processes. These types of confidential information and trade secrets can be difficult to protect. We seek to protect this confidential information, in part, through agreements with our employees, consultants, and third parties, as well as confidentiality policies and audits, although these may not always be successful in protecting our trade secrets and confidential information.

One or more of our products could be subject to early competition from generic drugs and biosimilars.

Certain of our products are approved as drug products under the provisions of the FDCA, which may render it susceptible to potential competition from generic manufacturers via the Hatch-Waxman Act and ANDA process. Other of our products may be susceptible to challenges by entry of biosimilars through the route established under the Biologics Price Competition and Innovation Action of 2009.

Although we intend to vigorously enforce our intellectual property rights, there can be no assurance that we will prevail in our enforcement or defense of our patent rights. Our existing patents could be invalidated, found unenforceable, or found not to cover a generic form of our product.

RISKS RELATED TO RELIANCE ON OTHER PARTIES

The loss of any of our non-exclusive, sole-source or single source suppliers, a shortage of related supplies or an increase in the price of inventory supplied to us could have an adverse effect on our business, financial condition and results of operations.

We purchase certain supplies used in our manufacturing processes from non-exclusive, or single sources due to quality considerations, costs or constraints resulting from regulatory requirements. We depend on certain single-source suppliers for key materials and services necessary to manufacture the majority of our products and certain product candidates. For example, we rely on a single-source supplier to provide us with Alhydrogel in sufficient quantities to meet our needs to manufacture CYFENDUS and BioThrax vaccines

and the specialty plasma in our hyperimmune specialty plasma products and certain ingredients for the ACAM2000 vaccine. We also rely on single-source suppliers for the materials necessary to produce NARCAN®, such as the naloxone active pharmaceutical ingredient and other excipients, along with the vial, stopper and device.

Where a particular single-source supply relationship is terminated, we may not be able to establish additional or replacement suppliers for certain components or materials quickly. This is largely due to the FDA approval system, which mandates validation of materials prior to use in our products and product candidates, and the complex nature of manufacturing processes. In addition, we may lose a sole-source supplier due to, among other things, the acquisition of a supplier by a competitor (which may cause the supplier to stop selling its products to us) or the bankruptcy of such a supplier, which may cause the supplier to cease operations. Any reduction or interruption by a sole-source supplier of the supply of materials or key components used in the manufacturing of our products or product candidates, a reduction in quality or an increase in the price of those materials or components could adversely affect us. If we are unable to locate or establish alternative suppliers, our ability to manufacture our products and product candidates could be adversely affected and could harm our revenues, cause us to fail to satisfy contractual commitments, lead to a termination of one or more of our contracts or lead to delays in our clinical trials, any of which could be costly to us and otherwise materially harm our business, financial condition, operating results and cash flows.

We depend on third parties to conduct many of our clinical and non-clinical trials. If these third parties do not perform as contractually required or as we expect, we may not be able to obtain regulatory approval for or commercialize our product candidates and, as a result, our business, financial condition, operating results and cash flows may suffer.

We depend on third parties, such as independent clinical investigators, contract research organizations and other third-party service providers, to conduct the clinical and non-clinical trials of our product candidates and expect to continue to do so. We rely heavily on these third parties for successful execution of our clinical and non-clinical trials, but do not exercise day-to-day control over their activities. Our reliance on these service providers does not relieve us of our regulatory responsibilities, including ensuring that our trials are conducted in accordance with good clinical practice regulations and the plan and protocols contained in the relevant regulatory application. In addition, these organizations may not complete these activities on our anticipated or desired timeframe. We also may experience unexpected cost increases that are beyond our control. Problems with the timeliness or quality of the work of a contract research

23

organization or other third party may lead us to seek to terminate the relationship and use an alternative service provider, which may prove difficult, costly and result in a delay of our trials. Any delay in or inability to complete our trials could delay or prevent the development, approval and commercialization of our product candidates.

In certain cases, government entities and non-governmental organizations ("NGOs") conduct studies of our product candidates, and we may seek to rely on these studies in applying for marketing approval for certain of our product candidates. These government entities and NGOs have no obligation or commitment to us to conduct or complete any of these studies or clinical trials and may choose to discontinue these development efforts at any time. Furthermore, government entities depend on annual Congressional appropriations to fund their development efforts, which may not be approved.

If we are unable to obtain any necessary third-party services on acceptable terms or if these service providers do not successfully carry out their contractual duties or meet expected deadlines, our efforts to obtain regulatory approvals for our product candidates may be delayed or prevented.

LEGAL AND REPUTATIONAL RISKS

Our financial condition and operating results could be adversely impacted by unfavorable results of legal proceedings or government investigations.

We are subject to various claims, legal proceedings and government investigations that have not yet been fully resolved, including stockholder derivative and putative class action lawsuits, and new matters may arise in the future. In addition, agreements entered into by us sometimes include indemnification provisions which can subject us to costs and damages in the event of a claim against an indemnified third party. The number of claims, legal proceedings and government investigations involving us, and the alleged magnitude of such claims, proceedings and government investigations, has generally increased over time and may continue to increase. Certain of these actions include, and future actual or threatened legal actions may include, claims for substantial and indeterminate amounts of damages, or may result in other actions adverse to us.

For example, multiple purported class action lawsuits have been filed against us and certain of our current and former senior officers in the United States District Court for the District of Maryland seeking unspecified damages on behalf of a putative class of persons who purchased or otherwise acquired shares of our common stock during various date ranges. The complaints, allege, among other things, that we made materially false and misleading statements regarding our procedures and quality controls relating to vaccine production, in violation of federal securities laws. As another example, multiple stockholder

derivative lawsuits were filed in The Court of Chancery of the State of Delaware and the United States District Court for the District of Maryland on behalf of the Company against certain current and former officers and directors for breach of fiduciary duties, waste of corporate assets, unjust enrichment and insider trading, each allegation related to the Company’s capabilities to manufacture COVID-19 vaccine bulk drug substance. In addition to monetary damages, the complaints seek the implementation of multiple corporate governance and internal policy changes.

Regardless of merit, litigation can be both time-consuming and disruptive to our operations and cause significant expense and diversion of management’s attention. The outcome of litigation or government investigations is also inherently uncertain. If one or more legal matters were resolved against us or an indemnified third party in a reporting period for amounts above management’s expectations, our financial condition and operating results for that reporting period could be materially adversely affected. Further, such an outcome could result in significant compensatory, punitive or trebled monetary damages, disgorgement of revenue or profits, remedial corporate measures or injunctive relief against us and could require us to change our business practices or limit our ability to offer certain products and services, all of which could materially adversely affect our financial condition and operating results. While we maintain insurance coverage for certain types of claims, such insurance coverage may be insufficient to cover all losses or all types of claims that may arise.

We rely significantly on information technology systems and any cyber security incidents, unauthorized access or other failure, inadequacy, interruption or security lapse of that technology could harm our ability to operate our business effectively or result in data leakage of proprietary or confidential business or employee information.

Our business is increasingly dependent on critical, complex and interdependent information technology systems, including Internet-based systems, to support business processes as well as internal and external communications. We previously contracted with the USG and pharmaceutical companies for the development and manufacture of a significant quantity of COVID-19 vaccines which, raised our security profile, and heightened potential risks that malicious actors may seek to disrupt our systems or misappropriate our information. The size and complexity of our computer systems and those of many of our business partners, collaborators and other third parties make them potentially vulnerable to interruption, invasion, computer viruses, destruction, unauthorized or malicious intrusion and additional related disruptions, which may result in the impairment of production and key business processes. Our systems and information are also potentially vulnerable to cyber security incidents through user error, phishing scams or

24

malfeasance, as well as cyber security incidents involving our employees, business partners, collaborators or other third parties, any of which may expose sensitive data to unauthorized persons. Our systems and those of our business partners and collaborators have in the past been, and in the future likely will be subject to computer viruses, malicious codes, unauthorized access and other cyber security incidents. We are not aware of any significant impact on our operations or financial results from such incidents although, as of the date of this report, we are assessing the potential impact of a cyber security incident involving misuse of authorized access by a business partner of which we became aware in October 2023.

No system of protection is adequate to protect against all such threats, even if they are deemed to be industry standard, and there can be no assurance that we will be able to repel any such attacks. Cyber security incidents could lead to the loss of trade secrets or other intellectual property or the public exposure of personal information, including sensitive personal information, of our employees, clinical trial patients, customers and others. Responding to any such threats may also be expensive and time-consuming. Any such unauthorized access to our information, whether through an incident involving our information technology systems or those of our business partners, collaborators or other third parties, could disrupt our business operations, result in the loss of assets, and have a material adverse effect on our reputation, business, financial condition, or results of operations. While the Company has experienced non-material cyber incidents involving third-party vendors, the Company's continued use of third parties in its business yields the potential for material cyber security incidents that may harm business operations.

A significant business disruption or a breach in security resulting in misappropriation, theft or sabotage with respect to proprietary or confidential business or employee information could result in significant financial losses, legal, business or reputational harm to us, compromise our business prospects and our commitments to the USG or other customers, any of which could materially and adversely affect our business, financial condition and operating results.

We face product liability exposure, which could cause us to incur substantial liabilities and negatively affect our business, financial condition and results of operations.

We face an inherent risk of product liability exposure related to the sale of our products, any other products that we successfully acquire or develop and the testing of our product candidates in clinical trials.

One measure of protection against such lawsuits is coverage under the PREP Act, which was signed into law in December 2005. The PREP Act creates liability protection for manufacturers of biodefense countermeasures when

the Secretary of HHS issues a declaration for their manufacture, administration or use. A PREP Act declaration is meant to provide liability protection from all claims under federal or state law for loss arising out of the administration or use of a covered countermeasure under a government contract. The Secretary of HHS has issued PREP Act declarations covering countermeasures for smallpox, mpox, and other orthopox; anthrax; and botulinum toxin. These declarations apply to certain of our products, namely BioThrax, ACAM2000, raxibacumab, Anthrasil, BAT and VIGIV products, as covered countermeasures. Manufacturers are not entitled to protection under the PREP Act in cases of willful misconduct or for cases brought in non-U.S. tribunals or under non-U.S. law. We cannot predict whether the Secretary of HHS will renew the declarations when they expire, whether Congress will fund the relevant PREP Act compensation programs, or whether the necessary prerequisites for immunity would be triggered with respect to our products or product candidates.

Additionally, certain of our products, namely BioThrax and RSDL, are under the SAFETY Act, which provides certain product liability limitations for qualifying anti-terrorism technologies for claims arising from or related to an act of terrorism. Although BioThrax and RSDL are designated and certified under the SAFETY Act, the law may not provide adequate protection from claims made against us.

If we cannot successfully defend ourselves against future claims that our products or product candidates caused injuries and if we are not entitled to indemnity by the USG, or the USG does not honor its obligations to us under the PREP Act or SAFETY Act, or if the liability protections under the PREP Act and SAFETY Act are not adequate to cover all claims, we may incur substantial liabilities. Regardless of merit or eventual outcome, product liability claims may result in:

•decreased demand or withdrawal of a product;

•injury to our reputation;

•withdrawal of clinical trial participants;

•costs to defend the related litigation;

•substantial monetary awards to trial participants or patients;

•loss of revenue; and

•an inability to commercialize products that we may develop.

The amount of insurance that we currently hold may not be adequate to cover all liabilities that we may incur. Further product liability insurance may be difficult and expensive to obtain. We may not be able to maintain insurance coverage at a reasonable cost and we may not be able to obtain insurance coverage that will be adequate

25

to satisfy all potential liabilities. For example, we may not have sufficient insurance against potential liabilities associated with a possible large-scale deployment of BioThrax vaccine as a countermeasure to a bioterrorism threat. We rely on PREP Act protection for BioThrax, raxibacumab, ACAM2000, Anthrasil, BAT and VIGIV products, and SAFETY Act protection for BioThrax and RSDL products in addition to our insurance coverage to help mitigate our product liability exposure for these products. Additionally, potential product liability claims related to our commercial products, including NARCAN®, may be made by patients, health care providers or others who sell or consume these products. Such claims may be made even with respect to those products that possess regulatory approval for commercial sale. Claims or losses in excess of our product liability insurance coverage could have a material adverse effect on our business, financial condition, operating results and cash flows.

FINANCIAL RISKS

We have incurred significant indebtedness in connection with our acquisitions and servicing our debt requires a significant amount of cash. We may not have sufficient cash flow from our operations to pay our substantial debt.

Our ability to make scheduled payments of the principal of, to pay interest on or to further refinance our indebtedness depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. We may also seek additional debt financing to support our ongoing activities or to provide additional financial flexibility. Debt financing can have significant adverse consequences for our business, including:

•requiring us to dedicate a substantial portion of cash flows from operations to payment on our debt, which would reduce available funds for other corporate initiatives;

•increasing the amount of interest that we have to pay on debt with variable interest rates, if market rates of interest increase, to the extent we are unable to offset such risk through our hedging instruments;

•subjecting us, as under our Senior Secured Credit Facilities and the indenture governing the Senior Unsecured Notes, to restrictive covenants that reduce our ability to take certain corporate actions, acquire companies, products or technology, or obtain further debt financing;

•requiring us to pledge our assets as collateral, which could limit our ability to obtain additional debt financing;

•limiting our flexibility in planning for, or reacting to, general adverse economic and industry conditions; and

•placing us at a competitive disadvantage compared to our competitors that have less debt, better debt servicing options or stronger debt servicing capacity.

We may not have sufficient funds or be able to obtain additional financing to pay the amounts due under our indebtedness. In addition, failure to comply with the covenants under our Senior Secured Credit Facilities and other debt agreements, including the maintenance of a specified consolidated net leverage ratio, debt service coverage ratio, consolidated EBITDA level, minimum liquidity level and required liquidity raise under our Senior Secured Credit Facilities, could result in an event of default under those agreements. An event of default could result in the acceleration of amounts due under a particular debt agreement and a cross default and acceleration under other debt agreements, and we may not have sufficient funds to pay or be able to obtain additional financing to make any accelerated payments.

Our current indebtedness restricts and any additional debt financing may restrict the operation of our business and limit the cash available for investment in our business operations.

The Senior Secured Credit Facilities include a $450.0 million Term Loan Facility which had an outstanding principal balance of $362.8 million as of December 31, 2022 and the ability to borrow up to $600.0 million under our Revolving Credit Facility of which we had $598.0 million of outstanding borrowings as of December 31, 2022. On August 7, 2020, we completed an offering of $450.0 million aggregate principal amount of Senior Unsecured Notes, of which $353.0 million of the net proceeds were used to pay down our Revolving Credit Facility. We may also seek additional debt financing to support our ongoing activities or to provide additional financial flexibility. Debt financing can have significant adverse consequences for our business, including:

•the level, timing and cost of product sales and CDMO services;

•the extent to which we acquire or invest in and integrate companies, businesses, products or technologies;

•the acquisition of new facilities and capital improvements to new or existing facilities;

•the payment obligations under our indebtedness;

•the scope, progress, results and costs of our development activities;

26

•our ability to obtain funding from collaborative partners, government entities and non-governmental organizations for our development programs;

•the extent to which we repurchase common stock under any future share repurchase program; and

•the costs of commercialization activities, including product marketing, sales and distribution.

In addition, our Senior Secured Credit Facilities and our Senior Unsecured Notes each contain cross-default provisions whereby a default under one agreement would likely result in cross defaults under agreements covering other indebtedness. The occurrence of a default under any of these arrangements would permit the holders of the notes or the lenders under our Senior Secured Credit Facilities to declare all amounts outstanding under those borrowing arrangements to be immediately due and payable, and there is no assurance that we would have sufficient funds to satisfy any such accelerated obligations.

Our hedging programs have been, and any hedging program we initiate in the future will be subject to counterparty default risk.

From time to time, we manage our interest rate risk in part by entering into interest rate swaps with a number of counterparties to swap a portion of our indebtedness that is based on variable interest rates to a fixed rate. As a result, when we are party to such interest rate swaps, we are subject to the risk that the counterparty to one or more of these contracts defaults on its performance under the contract. During an economic downturn, the counterparty's financial condition may deteriorate rapidly and with little notice and we may be unable to take action to protect our exposure. In the event of a counterparty default, we could incur losses, which may harm our business and financial condition. In the event that one or more of our counterparties becomes insolvent or files for bankruptcy, our ability to eventually recover any losses suffered as a result of that counterparty's default may be limited by the liquidity of the counterparty.

We require significant additional funding to be able to continue as a going concern and we may be unable to raise capital when needed or on acceptable terms, which would harm our ability to grow our business, and our results of operations and financial condition. In addition, any capital we raise may result in dilution to our current stockholders.

As of December 31, 2022, we had unrestricted cash and cash equivalents of $642.6 million and remaining capacity under our Revolving Credit Facility of $0.7 million. Also as of December 31, 2022, there was $598.0 million outstanding under our Revolving Credit Facility and $362.8 million under our Term Loan Facility that mature in

October 2023, which is within one year of the date that the Company’s consolidated financial statements are issued for the year ended December 31, 2022. As a result, the Company determined that there is substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued. We will need to obtain substantial additional funding in connection with our continuing operations, which cannot be assured.

If our capital resources are insufficient to meet our future capital requirements, we will need to finance our cash needs through public or private equity or debt offerings, bank loans or collaboration and licensing arrangements. In August 2021, we filed an automatic shelf registration statement, which immediately became effective under SEC rules. For so long as we continue to satisfy the requirements to be deemed a “well-known seasoned issuer” under SEC rules, this shelf registration statement, effective until August 9, 2024, allows us to issue an unrestricted amount of equity, debt and certain other types of securities through one or more future primary or secondary offerings. If we do not file a new shelf registration statement prior to the expiration of our automatic shell registration statement (whether by lapse of time due to us no longer qualifying as a "well-known seasoned issuer"), the existing shelf registration statement will expire, and we will not be able to publicly raise capital or issue debt until a new registration statement is filed and becomes effective. There can be no assurance that we will be eligible to file an automatically effective shelf registration statement at a future date when we may need to raise funds publicly.

If we raise funds by issuing equity securities, including through our "at-the-market" equity program, our stockholders may experience dilution. Debt financing, if available, may involve agreements that include covenants, like those contained in our Senior Secured Credit Facilities and the indenture governing the Senior Unsecured Notes, limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures, pursuing acquisition opportunities or declaring dividends. If we raise funds through collaboration and licensing arrangements with third parties, it may be necessary to relinquish valuable rights to our technologies or product candidates or grant licenses on terms that may not be favorable to us. Our Senior Secured Credit Facilities as well as the indenture governing the Senior Unsecured Notes restrict our ability to incur additional indebtedness.

Economic conditions may make it difficult to obtain financing on attractive terms, or at all. If financing is unavailable or lost, our business, operating results, financial condition and cash flows would be adversely affected, and we could be forced to delay, reduce the scope of or eliminate many of our planned activities.

27

We may not maintain profitability in future periods or on a consistent basis.

Our profitability has been substantially dependent on product sales, which historically have fluctuated significantly from quarter to quarter, and we expect that they will continue to fluctuate significantly based primarily on the timing of our fulfillment of orders from the USG. We may not be able to achieve consistent profitability on a quarterly basis or sustain or increase profitability on an annual basis.

Impairment charges to our intangible assets or property, plant and equipment could have a material adverse effect on our business, results of operations and financial condition.

In accordance with GAAP, we are required to assess the value of our intangible assets and goodwill annually, or more frequently whenever events or changes in circumstances indicate potential impairment, such as changing market conditions or any changes in key assumptions. If the testing performed indicates that an asset may not be recoverable, we are required to record a non-cash impairment charge for the difference between the carrying value of the asset and its implied fair value in the period the determination is made.

We also periodically monitor the remaining net book values of our property, plant and equipment, or whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. For example, following the filing date of the Original Form 10-K, we performed recoverability tests on certain asset groups within the CDMO reporting unit during the three months ended June 30, 2023, and allocated and recognized a non-cash impairment charge of $306.7 million during the three months ended June 30, 2023 related to certain CDMO long-lived assets.

In addition, we annually perform a goodwill impairment evaluation, during the fourth quarter, or sooner if triggering events are identified. Following the filing date of the Original Form 10-K, during the three months ended September 30, 2023 as a result of continued market volatility, including significant declines in our market capitalization and revised financial outlook, we determined that a triggering event had occurred that required an evaluation of our goodwill for potential impairment. As a result of the quantitative assessments, we determined that our goodwill, which related to the MCM reporting unit within the Products segment, was fully impaired and recorded a $218.2 million non-cash goodwill impairment charge during the three months ended September 30, 2023.

We have a significant amount of intangible assets and property, plant and equipment on our balance sheet. The impairment tests require us to make an estimate of the fair value of our reporting units. An impairment could be

recorded as a result of changes in assumptions, estimates or circumstances, some of which are beyond our control. Since a number of factors may influence determinations of fair value, we are unable to predict whether impairments of intangible assets and property, plant and equipment will occur in the future, and we can provide no assurance that continued conditions will not result in future impairments of these assets. The future occurrence of a potential indicator of impairment could include matters such as (i) a decrease in expected net earnings, (ii) adverse equity market conditions, (iii) a decline in current market multiples, (iv) a decline in our common stock price, (v) a significant adverse change in legal factors or the general business climate, and (vi) an adverse action or assessment by a regulator. Any such impairment would result in us recognizing a non-cash charge in our consolidated balance sheets, which could adversely affect our business, results of operations and financial condition.

The accuracy of our financial reporting depends on the effectiveness of our internal control over financial reporting.

We have identified material weaknesses in our internal control over financial reporting and have restated prior period financial statements that resulted from one of these material weaknesses, which may raise questions regarding the accuracy and reliability of our financial statements and our ability to report accurately in the future.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected on a timely basis. As described in Part II, Item 9A, “Controls and Procedures – Management’s Report on Internal Control Over Financial Reporting” in this Amendment, during the process of preparing the financial statements as of and for the year ended December 31, 2022, we determined that we had a material weakness related to our inventory accounting. Subsequently, in connection with the preparation of the financial statements as of and for the periods ended September 30, 2023, we determined that we had a material weakness related to the calculation and review of the Company's net state deferred tax liability and that this material weakness had existed as of December 31, 2022 and resulted in a material misstatement to our consolidated financial statements for the period ended December 31, 2022. Due to the existence of these material weaknesses, our management concluded that as of December 31, 2022 our internal control over financial reporting was not effective and we were required to restate prior period financial statements, including disclosing that the financial statements included in the Original Form 10-K could no longer be relied upon and filing this Amendment to restate our financial statements.

28

We determined that we remediated our internal weakness with respect to inventory accounting as of March 31, 2023 and we are taking steps to remediate the material weakness related to the calculation and review of net state deferred tax liability. In addition, we have restated the financial statements included in the Original Form 10-K to correct the errors that were identified as a result of the material weakness regarding our calculation and review of the Company's net state deferred tax liability, and corrected other unrelated errors that were addressed as out-of-period adjustments in previously filed financial statements that were not material, individually or in the aggregate, to those financial statements. However, we cannot provide any assurance that the measures we have taken to date and we intend to implement will be sufficient to remediate the material weakness regarding net state deferred tax liability that we have identified, or to avoid additional material weaknesses from occurring in the future. The material weaknesses in our internal control over financial reporting and the restatement of our prior financial statements may raise significant questions regarding the accuracy and reliability of our filed financial statements and our ability to report in an accurate and timely manner in the future. These material weaknesses and resulting errors in our financial statements, or those that may occur in the future, could have an adverse effect on our ability to meet our reporting obligations, which could cause our investors to lose confidence in our publicly reported information, cause the market price of our stock to decline, harm our reputation, business and financial results, and expose us to stockholder litigation and sanctions or investigations by the SEC or other regulatory authorities.

The expansion of our international operations increases our risk of exposure to credit losses.

As we continue to expand our business activities with foreign governments in certain countries that have experienced deterioration in credit and economic conditions or otherwise, our exposure to uncollectible accounts will rise. Global economic conditions and liquidity issues in certain countries have resulted and may continue to result in delays in the collection of accounts receivable and may result in credit losses. Future governmental actions and customer specific actions may require us to re-evaluate the collectability of our accounts receivable and we may potentially incur credit losses that materially impact our operating results.

RISKS RELATED TO STRATEGIC ACQUISITIONS, DIVESTITURES AND COLLABORATIONS

We may not be successful in identifying, structuring or acquiring businesses and products to drive our growth.

We may not be successful in identifying, effectively evaluating, structuring, acquiring or in-licensing, and developing and commercializing additional products on favorable terms, or at all. Competition for attractive

product opportunities is intense and may require us to devote substantial resources, both managerial and financial, to an acquisition opportunity. A number of more established companies are also pursuing strategies to acquire or in-license products in the biopharmaceutical field. These companies may have a competitive advantage over us due to their size, cash resources, cost of capital, effective tax rate and greater clinical development and commercialization capabilities.

Acquisition efforts can consume significant management attention and require substantial expenditures, which could detract from our other programs. In addition, we may devote significant resources to potential acquisitions that are never completed. Even if we are successful in acquiring a company or product, it may not result in a successfully developed or commercialized product or, even if an acquired product is commercialized, competing products or technologies could render a product noncompetitive, uneconomical or obsolete. Moreover, the cost of acquiring other companies or in-licensing products could be substantial, and in order to acquire companies or new products, we may need to incur substantial debt or issue dilutive securities.

If we are unsuccessful in our efforts to identify and acquire other companies, products, or in-license and develop additional products, or if we acquire or in-license unproductive assets, it could have a material adverse effect on the growth of our business, and we could be compelled to record significant impairment charges to write-down the carrying value of our acquired intangible assets, which could materially harm our business, financial condition, operating results and cash flows.

Our failure to successfully integrate acquired businesses and/or assets into our operations could adversely affect our ability to realize the benefits of such acquisitions and, therefore, to grow our business.

We may not be able to integrate any acquired business successfully or operate any acquired business profitably. In addition, cost synergies, if achieved at all, may be less than we expect, or may take greater time to achieve than we anticipate.

Issues that could delay or prevent successful integration or cost synergies of an acquired business or products include, among others:

•retaining existing customers and attracting new customers;

•retaining key employees;

•diversion of management attention and resources;

29

•conforming internal controls, policies and procedures, business cultures and compensation programs;

•consolidating corporate and administrative infrastructures;

•successfully executing technology transfers and obtaining required regulatory approvals;

•consolidating sales and marketing operations;

•identifying and eliminating redundant and underperforming operations and assets;

•assumption of known and unknown liabilities;

•coordinating geographically dispersed organizations;

•managing tax costs or inefficiencies associated with integrating operations; and

•risks associated with intellectual property rights related to an acquisition or collaboration.

If we are unable to successfully integrate pending and future acquisitions with our existing businesses, or operate any acquired business profitably, we may not obtain the advantages that the acquisitions were intended to create, which may materially adversely affect the growth of our business, financial condition, operating results and cash flows.

We may not realize the expected benefits of the sale of our travel health business to Bavarian Nordic.

On May 15, 2023, pursuant to the Purchase and Sale Agreement, we completed the previously announced sale to Bavarian Nordic of our travel health business, including rights to Vaxchora and Vivotif, as well as our development-stage chikungunya vaccine candidate CHIKV VLP, our manufacturing site in Bern, Switzerland and certain of our development facilities in San Diego, California for a cash purchase price of $270.0 million, subject to certain customary adjustments. In addition, we may receive milestone payments of up to $80.0 million related to the development of CHIKV VLP and receipt of marketing approval and authorization in the U.S. and Europe, and sales-based milestone payments of up to $30.0 million based on aggregate net sales of Vaxchora and Vivotif in calendar year 2026.

There can be no assurance that we will be able to realize in full the expected benefits of the transaction. If we are unable to or do not realize the expected strategic, economic, or other benefits of the transaction, it could adversely affect our business and financial position.

RISKS RELATED TO OWNERSHIP OF OUR COMMON STOCK

Our business or our share price could be negatively affected as a result of the actions of stockholders.

In recent years, some stockholders have placed increasing pressure on publicly traded companies in our industry and others to effect changes to corporate governance practices, executive compensation practices, social and environmental practices and to undertake certain corporate actions. This may be true even if they only hold a minority of shares. In addition, many institutional investors are increasingly focused on environmental, social, and corporate governance ("ESG") factors. These investors may be seeking enhanced ESG disclosures or to implement policies adverse to our business. There can be no assurances that stockholders will not publicly advocate for us to make corporate governance changes or engage in certain corporate actions. Responding to challenges from stockholders, such as proxy contests, media campaigns or other public or private means, could be costly and time consuming and could have an adverse effect on our reputation and divert the attention and resources of management and our board of directors, which could have an adverse effect on our business and operational results. Any such stockholder actions or requests, or the mere public presence of stockholders with a reputation for taking such actions among our investor base, could also cause the market price of our common stock to experience periods of significant volatility.

Provisions in our certificate of incorporation and by-laws and under Delaware law may discourage acquisition proposals, delay a change in control or prevent transactions that stockholders may consider favorable.

Provisions in our certificate of incorporation and by-laws may discourage, delay or prevent a merger, acquisition or other changes in control that stockholders may consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares. These provisions may also prevent or frustrate attempts by our stockholders to replace or remove our management.

These provisions include:

•the classification of our directors;

•limitations on changing the size of our board of directors;

•limitations on the removal of directors;

•limitations on filling vacancies on the board of directors;

30

•advance notice requirements for stockholder nominations of candidates for election to the board of directors and other proposals;

•the inability of stockholders to act by written consent;

•the inability of stockholders to call special meetings; and

•the ability of our board of directors to designate the terms of and issue a new series of preferred stock without stockholder approval.

The affirmative vote of a majority of our board of directors or the holders of our capital stock representing at least 75% of the voting power of all outstanding stock entitled to vote is required to amend or repeal the above provisions of our certificate of incorporation or by-laws. The affirmative vote of either a majority of the directors present at a meeting of our board of directors or holders of our capital stock representing at least 75% of the voting power of all outstanding stock entitled to vote is required to amend or repeal our by-laws.

In addition, we are subject to Section 203 of the Delaware General Corporation Law (Section 203). In general and subject to certain exceptions, Section 203 prohibits a publicly-held corporation from engaging in a business combination with an interested stockholder, generally a person which, together with its affiliates, owns or within the last three years has owned 15% or more of the corporation's voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. Accordingly, Section 203 may discourage, delay or prevent a change in control of us.

Our board of directors may implement a new stockholder rights plan without stockholder approval, which could prevent a change in control of us in instances in which some stockholders may believe a change in control is in their best interests.

Our board of directors may implement a stockholder rights plan without stockholder approval, which may have anti-takeover effects, potentially preventing a change in control of us in instances in which some stockholders may believe a change in control is in their best interests. This could cause substantial dilution to a person or group that attempts to acquire us on terms that our board of directors does not believe are in our best interests or those of our stockholders and may discourage, delay or prevent a merger or acquisition that stockholders may consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares.

Our stock price is volatile, and purchasers of our common stock could incur substantial losses.

Our stock price has been, and is likely to continue to be, volatile. The market price of our common stock could fluctuate significantly for many reasons, including in response to the risks described in this “Risk Factors” section, or for reasons unrelated to our operations, such as reports by industry analysts, investor perceptions or negative announcements by our customers, competitors or suppliers regarding their own performance, as well as industry conditions and general financial, economic and political instability. From November 15, 2006, when our common stock first began trading on the New York Stock Exchange, through November 29, 2023, our common stock has traded as high as $137.61 per share and as low as $1.81 per share. The market price of our common stock may be influenced by many factors, including, among others:

•contracts, decisions and procurement policies by the USG affecting our anthrax vaccines and our other products and product candidates;

•the success of competitive products or technologies;

•results of clinical and non-clinical trials of our product candidates;

•announcements of acquisitions, financings or other transactions by us;

•litigation or legal proceedings;

•public concern as to the safety of our products;

•termination or delay of a development program;

•the recruitment or departure of key personnel;

•variations in our product revenue and profitability; and

•the other factors described in this “Risk Factors” section.

Because we currently do not pay dividends, investors will benefit from an investment in our common stock only if it appreciates in value.

We currently do not pay dividends on our common stock. Our Senior Secured Credit Facilities and the indenture governing our Senior Unsecured Notes limit and any future debt agreements that we enter into may limit our ability to pay dividends. As a result, capital appreciation, if any, of our common stock will be the sole source of gain for our stockholders based on current expectations.

Future sales of our common stock or other securities convertible into common stock, or the perception that such sales or issuances could occur, could result in dilution of

31

our stockholders and could cause our share price to decline.

Our board of directors is authorized, without stockholder approval, to cause us to issue additional shares of our common stock or to raise capital through the issuance of preferred shares or the sale of debt securities that are convertible into common stock, options, warrants and other rights, on terms and for consideration as our board of directors in its sole discretion may determine. In addition, under the Credit Agreement Amendment that we entered into subsequent to the filing of the Original Form 10-K, we are required to increase our liquidity by April 30, 2024 by raising at least $75.0 million of equity or unsecured indebtedness. We also require substantial additional funding to be able to continue as a going concern and we may seek to achieve such funding through future sales of our common stock or other securities convertible into our common stock. Sales of substantial amounts of our common stock or the issuance of preferred shares, convertible debt, options, restricted stock units, performance stock units, warrants and other rights, or the perception that such sales or issuances could occur could cause the market price of our common stock to decrease significantly. We cannot predict the effect, if any, of future sales of our common stock or any preferred shares, convertible debt securities, options, restricted stock units, performance stock units, warrants or other rights or the availability of our common stock for future sales on the value of our common stock.

GENERAL RISK FACTORS

Our success is dependent on our continued ability to attract, motivate and retain key personnel, and any failure to attract or retain key personnel may negatively affect our business.

Because of the specialized scientific nature of our business, our ability to develop products and to compete with our current and future competitors largely depends upon our ability to attract, retain and motivate highly qualified managerial and key scientific and technical personnel (including quality and manufacturing personnel). If we are unable to retain the services of one or more of the principal members of senior management or other key employees, our ability to implement our business strategy could be materially harmed. We face intense competition for qualified employees from biopharmaceutical companies, research organizations and academic institutions. Attracting, retaining or replacing these personnel on acceptable terms may be difficult and time-consuming given the high demand in our industry for similar personnel. We believe part of being able to attract, motivate and retain personnel is our ability to offer a competitive compensation package, including equity incentive awards. If we cannot offer a competitive compensation package to attract and retain the qualified personnel necessary for the continued development of our

business, we may not be able to maintain our operations or grow our business.

PART II

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis is meant to provide material information relevant to an assessment of the financial condition and results of operations of our company, including an evaluation of the amounts and uncertainties of cash flows from operations and from outside resources, so as to allow investors to better view our company from management’s perspective. You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and the related notes and other financial information included elsewhere in this Amendment. Some of the information contained in this discussion and analysis or set forth elsewhere in this Amendment, including information with respect to our plans and strategy for our business and financing, includes forward-looking statements that involve risks and uncertainties. You should carefully review the "Cautionary Note Regarding Forward-Looking Statements" and "Risk Factors" sections of this Amendment for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

RESTATEMENT

As part of the Company’s quarterly review process related to the preparation of its unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2023, the Company determined that its net state deferred tax liability was overstated as of December 31, 2022, resulting in an understatement of the income tax benefits reflected on the Company’s consolidated statement of operations. This material error was associated with the use of incorrect state tax rates in the calculation of state deferred tax assets and related valuation allowances, which are non-cash items that resulted in an understatement of the Company's income tax benefit of $11.7 million for the year ended December 31, 2022. The Company has determined that the correction of this misstatement is material to the Company’s previously reported results of operations and require a restatement of the Company’s audited consolidated financial statements as of and for the year ended December 31, 2022. In connection with the restatement to correct this material

33

error, the Company determined that it is appropriate to revise the financial statements as of and for the years ending December 31, 2022, 2021 and 2020 included in this Form 10-K/A to correct other unrelated immaterial errors that were previously either unrecorded or recorded as out-of-period adjustments.

The effects of the restatement and immaterial revisions, including the related income tax impacts, have been corrected in all impacted tables and footnotes throughout these consolidated financial statements. For additional information and a detailed discussion of these error corrections, refer to Item 8 of Part II, "Financial Statements and Supplemental Data — Notes to Consolidated Financial Statements — Note 2, Restatement of consolidated financial statements".

For a description of the control deficiency identified by management as a result of the investigation and our internal reviews, and management's plan to remediate this deficiency, see Item 9A of Part II, "Controls and Procedures".

These services, which we refer to as "molecule-to-market" offerings, employ diverse technology platforms (mammalian, microbial, viral and plasma) across a network of nine geographically distinct development and manufacturing sites operated by us for our internal products and pipeline candidates and third-party CDMO services. We service both clinical-stage and commercial-stage projects for a variety of third-party customers, including government agencies, innovative pharmaceutical companies, and non-government organizations.

Full Year 2022 Executive Highlights

Asset Acquisition

During the year ended December 31, 2022, the Company acquired from Chimerix the exclusive worldwide rights to brincidofovir, including TEMBEXA® and other related assets. TEMBEXA is a medical countermeasure for smallpox approved by the FDA in June 2021.

Other Strategic Activities

2023 Organizational Restructuring Plan

On January 9, 2023, the Company announced an organizational restructuring plan (the “Plan”) intended to reduce operating costs, improve operating margins, and continue advancing the Company’s ongoing commitment to profitable growth. The Plan includes a reduction of the Company’s current workforce by approximately five percent. Decisions regarding the elimination of positions are subject to local law and consultation requirements in certain countries, as well as the Company’s business needs.

35

The Company estimates that it will incur approximately $9.0 million to $11.0 million of charges in connection with the Plan, which it expects to incur in the first quarter of fiscal 2023. These charges consist primarily of charges related to employee transition, severance payments, employee benefits, and share-based compensation. These actions, in combination with other cost reduction initiatives, are expected to result in annualized savings of over $60.0 million when fully implemented.

Agreement to Sell Travel Business

On February 15, 2023, we entered into the Sale Agreement with Bavarian Nordic, under which we agreed to sell our travel health business, including rights to Vaxchora and Vivotif, as well as our development-stage chikungunya vaccine candidate CHIKV VLP, our manufacturing site in Bern, Switzerland and certain of our development facilities in San Diego, California for a cash purchase price of $270.0 million, subject to certain customary adjustments. In addition, we may receive milestone payments of up to $80.0 million related to the development of CHIKV VLP and receipt of marketing approval and authorization in the U.S. and Europe, and sales-based milestones payments of up to $30.0 million based on aggregate net sales of Vaxchora and Vivotif in calendar year 2026. Approximately 280 employees are expected to join Bavarian Nordic as part of the transaction.

The transaction is expected to close in the second quarter of 2023, subject to certain customary closing conditions, including (1) the expiration or earlier termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (2) receipt of required clearances and approvals under Spain’s competition laws, (3) receipt of certain Swiss real property approvals, (4) no material adverse effect having occurred with respect to the Business, and (5) certain other customary conditions.

Financial Operations Overview

Revenues

We generate product revenues from the sale of our marketed products and procured product candidates. The USG is the largest purchaser of our Government - MCM products and primarily purchases our products for the SNS, a national repository of medical countermeasures including critical antibiotics, vaccines, chemical antidotes, antitoxins, and other critical medical supplies. The USG primarily purchases our products under long-term, firm fixed-price procurement contracts, generally with annual options. Our opioid overdose treatment product, NARCAN® Nasal Spray, and our travel health products, Vivotif and Vaxchora, are sold commercially through wholesalers and distributors, physician-directed or standing order prescriptions at retail pharmacies and to state and local community healthcare agencies, practitioners and hospitals.

We also generate revenue from our CDMO services, which is based on our established development and manufacturing infrastructure, technology platforms and expertise. Our services include a fully integrated molecule-to-market CDMO services business offering across development services, drug substance and drug product for small to large pharmaceutical and biotechnology industry and government agencies/non-governmental organizations. From time to time, clients require suite reservations at our various manufacturing sites, which may be considered leases depending on the facts and circumstances.

We have received contracts and grant funding from the USG and other non-governmental organizations to perform R&D activities, particularly related to programs addressing certain CBRNE threats and EIDs.

Our revenue, operating results and profitability vary quarterly based on the timing of production and deliveries, the timing of manufacturing services performed and the nature of our business, which involves providing large scale bundles of products and services as needs arise. We expect continued variability in our quarterly financial results.

Cost of Product Sales and Services

Products - The primary expenses that we incur to deliver our products consist of fixed and variable costs. We determine the cost of product sales for products sold during a reporting period based on the average manufacturing cost per unit in the period those units were manufactured. Fixed manufacturing costs include facilities, utilities and amortization of intangible assets. Variable manufacturing costs primarily consist of costs for materials and personnel-related expenses for direct and indirect manufacturing support staff, contract manufacturing operations, sales-based royalties, shipping and logistics. In addition to the fixed and variable manufacturing costs described above, the cost of product sales depends on utilization of available manufacturing capacity. For our commercial sales, other associated expenses include sales-based royalties (which include fair value adjustments associated with contingent consideration), shipping, and logistics.

36

Services - The primary expenses that we incur to deliver our CDMO services consist of fixed and variable costs, including personnel, equipment, and facilities costs. Our manufacturing process includes the production of bulk material and performing drug product work for containment and distribution of biological products. For drug product customers, we receive work in process inventory to be prepared for distribution.

Research and Development Expenses ("R&D")

We expense R&D costs as incurred. Our R&D expenses consist primarily of:

▪personnel-related expenses;

▪fees to professional service providers for, among other things, analytical testing, independent monitoring or other administration of our clinical trials and obtaining and evaluating data from our clinical trials and non-clinical studies;

▪costs of CDMO services for our clinical trial material; and

▪costs of materials intended for use and used in clinical trials and R&D.

In many cases, we seek funding for development activities from external sources and third parties, such as governments and non-governmental organizations, or through collaborative partnerships. We expect our R&D spending will be dependent upon such factors as the results from our clinical trials, the availability of reimbursement of R&D spending, the number of product candidates under development, the size, structure and duration of any clinical programs that we may initiate, the costs associated with manufacturing and development of our product candidates on a large-scale basis for later stage clinical trials, and our ability to use or rely on data generated by government agencies.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist primarily of personnel-related costs and professional fees in support of our executives, sales and marketing, business development, government affairs, finance, accounting, information technology, legal, human resource functions and other corporate functions. Other costs include facility costs not otherwise included in cost of product sales and CDMO services or R&D expense.

Income Taxes

Uncertainty in income taxes is accounted for using a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. We recognize in our financial statements the impact of a tax position if that position is more likely than not of being sustained on audit, based on the technical merits of the position.

Management believes that the assumptions and estimates related to the provision for income taxes are critical to the Company’s results of operations. For the year ended December 31, 2022, income tax benefit totaled $7.4 million. For every 1% change in the 2022 effective rate, income tax expense would have changed by approximately $2.2 million.

For additional information on our uncertain tax positions and income tax expense, please see Note 14, "Income taxes" to our consolidated financial statements included in this Amendment.

Year Ended December 31, 2022 Compared with Year Ended December 31, 2021

Revenues and gross margin

Total revenues decreased $656.1 million to $1.1 billion in 2022. The decrease was primarily due to a decrease in Services revenue of $505.6 million, coupled with decreases in Contracts and Grants revenue of $92.8 million and Products revenue of $57.7 million.

Consolidated gross margin percentage decreased 19 percentage points to 36%. The decrease was primarily due to decreases in the Services segment and Products segment gross margins of $408.6 million and $99.7 million, respectively. Consolidated gross margin percentage excludes contracts and grants revenues because the related costs are R&D expenses.

See "Segment Results" for an expanded discussion of revenues and gross profit.

Unallocated corporate expenses

Research and Development Expenses

R&D expenses decreased $46.9 million to $188.3 million in 2022. The decrease was largely due to the non-cash write-off in 2021 of $38.0 million of the contract asset associated with the completion of the BARDA COVID-19 Development Public Private Partnership (as defined below), coupled with a decrease in spending for the Company's COVID-19 therapeutic product candidates along with a number of other developmental activities, partially offset by an increase in costs associated with the Company's Phase 3 study of our chikungunya virus-like particle vaccine candidate and pre-launch inventory related to CGRD-001.

Selling, General and Administrative Expenses

Selling, general and administrative expenses decreased $9.2 million to $339.5 million in 2022. The decrease was due to lower professional services and marketing expenses partially offset by increased employee costs, primarily due to increased travel costs. Selling, general and administrative costs as a percentage of total revenue increased 10.7 percentage points to 30.4% for the year ended December 31, 2022. The increase was due to a decrease in revenues during the period, partially offset by a decrease in selling, general and administrative expenses during the period.

Amortization of Intangible Assets

Amortization of intangible assets increased $1.4 million to $59.9 million in 2022. Apart from the addition of the intangibles related to the Company's acquisition of the worldwide rights to TEMBEXA in 2022, the composition of intangible assets amortized was largely consistent with 2021.

Goodwill Impairment

Goodwill impairment decreased $35.0 million to $6.7 million in 2022. The decrease was due to a smaller non-cash impairment charge taken in 2022 as compared with 2021. In 2022, as part of its annual goodwill impairment testing, the Company recognized a $6.7 million impairment charge to goodwill in the CDMO- Services reporting unit, reducing the goodwill balance to zero as of December 31, 2022.

There is the risk of future impairments in our reporting units as any further deterioration in their performance compared to forecast, changes in order volumes or delivery schedules for major customers, as well as any changes in economic forecasts and expected recovery in the biopharmaceutical industry, may require the Company to complete additional impairment tests in future quarters and could result in the reporting unit’s fair value falling below carrying value in subsequent quarters. In the event the Company experiences factors that it believes indicate a decline in fair value, including negative changes to long-term growth rates or if discount rates increase, we may be required to record impairments of goodwill and other identified intangible assets. Further, if the composition of the Company’s reporting unit’s assets and liabilities were to change and result in an increase in the reporting unit’s carrying value, it could lead to additional impairment testing and further impairment losses.

Total other income (expense), net

Total other expense, net increased $10.8 million to an expense of $49.0 million in 2022. The increase was due to a write-off of a tax indemnity receivable, which is offset in income tax provision, and unrealized foreign currency losses recorded related to the remeasurement of certain intercompany balances. Interest expense was largely consistent between periods.

39

Income tax provision

Income tax provision decreased $91.1 million to an income tax benefit of $7.4 million for the year ended December 31, 2022. The decrease was largely due to the decline in income before income taxes. The effective tax rate was 3% for the year ended December 31, 2022 as compared to 28% in 2021. The effective annual tax rate decreased largely due to the impact of a valuation allowance charge in the U.S., state and foreign jurisdictions, a charge due the Company’s indefinite reinvestment assertion, GILTI, and other permanent items. This is partially offset by tax credits, favorable rates in foreign jurisdictions, and the release of an indemnified unrecognized tax benefit.

Year Ended December 31, 2022 Compared with Year Ended December 31, 2021

Nasal Naloxone Products

Nasal Naloxone Product sales decreased $60.6 million to $373.7 million in 2022. The decrease was primarily driven by a reduction in commercial retail sales and a decrease in the price per unit following the launch of a generic version of NARCAN Nasal Spray 4mg in December 2021, partially offset by an increase in U.S. public interest and Canadian sales.

Anthrax Vaccines

Anthrax vaccine sales increased $14.5 million to $274.3 million in 2022. The increase in anthrax vaccine sales was primarily due to an increase in the number of doses sold as a result of the timing of deliveries to the USG in 2022 as compared with 2021, as well as an increase in sales to non-USG customers at a higher price per unit in 2022. Anthrax vaccine product sales are primarily made under annual purchase options exercised by the USG. Fluctuations in revenues result from the timing of the exercise of annual purchase options and the USG purchases and Company delivery of orders that follow.

40

ACAM2000

ACAM2000 sales decreased $143.1 million to $63.4 million in 2022. The decrease was primarily due to a lower number of units sold to the USG, partially offset by an increased number of units sold to non-U.S. customers at a higher price per unit. We are currently negotiating with HHS the terms of a third contract option for ACAM2000. The actual number of ACAM2000 doses to be procured in the future is dependent on certain timing and tiered-pricing terms that are subject to the discretion of HHS.

TEMBEXA

TEMBEXA sales, following the 2022 acquisition of worldwide rights to TEMBEXA, contributed $117.6 million in revenues in 2022.

Other Product Sales

Other product sales increased $13.9 million to $137.2 million in 2022. The increase was primarily due to increased sales of Anthrasil, Vivotif and RSDL products partially offset by decreased sales of VIGIV and BAT products.

Cost of Sales and Gross Margin

Cost of product sales increased $42.0 million, or 11%, to $424.6 million in 2022. The increase was primarily due to cost of sales for TEMBEXA following our 2022 acquisition of the worldwide rights for TEMBEXA. Excluding the acquisition related product costs, cost of product sales decreased $18.1 million, primarily due decreases in royalties paid for NARCAN sales and ACAM2000 product sales which were due to a reduced number of units sold to the USG and decreased expenses at our Bern facility due to higher facility utilization versus prior year. These were partially offset by inventory write-offs, primarily related to AV7909 and ACAM2000 and higher costs due to under-utilized capacity at our facilities.

Product gross margin percentage decreased 7 percentage points to 56% in 2022. The decrease was largely due to decreased sales volumes and inventory write-offs combined with a less favorable mix weighted more heavily to lower margin products. Adjusted gross margin percentage decreased 1 percentage point to 62% in 2022. Adjusted gross margin excludes the impact of non-cash items related to the changes in the fair value of contingent consideration of $2.6 million and the inventory step-up provision TEMBEXA inventory of $51.4 million.

Year Ended December 31, 2022 Compared with Year Ended December 31, 2021

Services Revenues

CDMO services revenue decreased $205.3 million to $105.0 million in 2022. The decrease was primarily due to $170.9 million less of combined revenue related to reduced production activities at the Company's Bayview facility as a result of a halt in manufacturing under the Janssen contract in first quarter of 2022 and the cessation of manufacturing activities under the AstraZeneca contract which occurred in 2021. Additionally, the decrease also reflects reduced

41

production at the Camden facility. The decreases were slightly offset by an increase in manufacturing activities at the Company's Winnipeg facility.

CDMO lease revenue decreased $300.3 million to $4.9 million in 2022. The decrease was primarily due to a reduction of $243.1 million associated with the completion of our COVID-19 development public-private partnership with BARDA in November 2021 and reduced lease revenues under the Janssen contract of $58.1 million.

Cost of Services and Gross Margin

Cost of Services decreased $97.0 million, or 27%, to $268.5 million in 2022. The decrease was primarily due to reduced production activities across our CDMO network, as well as a $41.5 million inventory write-off related to the Bayview facility in the second quarter of 2021, partially offset by increased costs at our Camden facility for additional investments in quality enhancement and improvement initiatives.

Services gross margin percentage decreased to (144)% in 2022. The decrease was primarily due to reduced production activities across our CDMO network including the completion of the Company's arrangement with BARDA in November 2021, the halt in manufacturing under the Janssen and AstraZeneca contracts and the decrease in margins at the Company's Camden facility due to additional investments in quality enhancement and improvement initiatives, including an increase in professional services costs.

OTHER REVENUE

Year Ended December 31, 2022 Compared with Year Ended December 31, 2021

Contracts and Grants

Contract and grants revenue decreased $92.8 million, or 69%, to $41.4 million in 2022. The decrease was primarily due to BARDA's completion of the CIADM agreement in November 2021 as well as decreases in development activities associated with various other externally funded research and development projects, most notably the Company's COVID-HIG therapeutic product candidate, as well as decreases in development activities for AV7909. Decreases were partially offset by revenue increases relating to indirect rate adjustments during the period.

Year Ended December 31, 2021 Compared with Year Ended December 31, 2020

Revenues and gross margin

Total revenues increased $196.3 million to $1.8 billion in 2021. The increase was primarily due to an increase in Services revenue of $143.1 million, coupled with increases in Products revenue of $34.1 million and Contracts and Grants revenue of $19.1 million.

Consolidated gross margin percentage decreased 9 percentage points to 54%. The decrease was primarily due to a decrease in the Services segment gross margin of $77.4 million, offset by an increase in Products segment gross margin of $43.5 million. Consolidated gross margin percentage excludes contracts and grants revenues because the related costs are R&D expenses.

See "Segment Results" for an expanded discussion of revenues and gross profit.

Unallocated corporate expenses

Research and Development Expenses

R&D expenses decreased $2.7 million to $235.2 million in 2021. The decrease was largely due to a decline in spending associated with the Company's COVID-HIG therapeutic product candidate as well as a decline in developmental activities associated with the Company's AV7909 product candidate.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $44.6 million to $348.7 million in 2021. The increase was primarily due to an increase in headcount and professional services as well as increased costs for defending and supporting the Company's corporate reputation.

Amortization of Intangible Assets

Amortization of intangible assets decreased $1.3 million to $58.5 million in 2021. The composition of intangible assets amortized was largely consistent with 2020.

Goodwill Impairment

As part of the Company's annual impairment testing which reflected the revised reporting unit structure from the Company's reorganization during the fourth quarter of 2021 the Company recognized a $41.7 million impairment of goodwill in the Commercial reporting unit.

Total other income (expense), net

Total other expense, net increased $11.6 million to an expense of $38.2 million in 2021. The increase was due to a write-off of a tax indemnity receivable, which is offset in income tax provision, and unrealized foreign currency losses recorded related to the remeasurement of certain intercompany balances. Interest expense was largely consistent between periods.

Income tax provision

Income tax provision decreased $22.4 million to an income tax provision of $83.7 million for the year ended December 31, 2021. The decrease was largely due to the decline in income before income taxes. The effective tax rate was 28% for the year ended December 31, 2021 as compared to 26% in 2020. The effective annual tax rate increased largely due to an increase in nondeductible expenses, specifically the impact of GILTI, impairment charge and other permanent items. This is partially offset by favorable rates in foreign jurisdictions.

Year Ended December 31, 2021 Compared with Year Ended December 31, 2020

Nasal Naloxone Products

Nasal Naloxone Product sales increased $123.1 million to $434.3 million in 2021. The increase was primarily driven by growth in unit sales of NARCAN to U.S. public interest customers and to a lesser extent the commercial retail markets. Increases in Canadian sales due to an increase in units sold also contributed to growth between 2021 and 2020. Additionally, the Company recorded limited revenues related to an authorized generic nasal naloxone product for the year ended December 31, 2021.

Anthrax Vaccines

Anthrax vaccine sales decreased $114.0 million to $259.8 million in 2021. The decrease in anthrax vaccine sales was primarily due to the timing of deliveries to the USG in 2021 as compared to 2020. During 2020, deliveries were larger than average due to the transition to AV7909 which had resulted in delayed deliveries the previous year. The price per unit of AV7909 was largely consistent year over year. Anthrax vaccine product sales are made under annual purchase options exercised by the USG. Fluctuations in revenues result from the timing of the exercise of annual purchase options and the USG purchases and Company delivery of orders that follow.

ACAM2000

ACAM2000 sales increased $6.2 million to $206.5 million in 2021. The increase was primarily due to standard inflationary price increases between 2021 and 2020 as the price per unit and number of units delivered remained consistent between 2020 and 2021. ACAM2000 product sales are made under recurring procurement contracts with the USG and any fluctuation in revenues are generally caused by the timing of delivery of orders.

45

Other Product Sales

Other product sales increased $18.8 million to $123.3 million in 2021. The increase was primarily due to an increase in the quantity of VIGIV offset by a decline in quantity of BAT. The change between 2021 and 2020 is primarily due to timing of deliveries to the SNS.

Cost of Sales and Gross Margin

Cost of product sales decreased $9.4 million, or 2%, to $382.6 million in 2021. The decrease was primarily due to contingent consideration charges for business combinations, as well as inventory write-offs associated with the Company's travel health vaccines of $44.3 million in 2020 that did not recur in 2021. This decrease was further impacted by declines in sales of Anthrax vaccines and other products that was partially offset by increased costs as a result of higher volume of certain products, mostly Nasal Naloxone Products.

Product gross margin percentage increased 3 percentage points to 63% in 2021. The increase was largely due to non-recurring charges in 2020 related to contingent consideration and inventory write-offs. Excluding those non-recurring charges, the gross profit margin decreased from 2020 and 2021 largely due to changes in product mix.

Services Revenues

CDMO services revenue increased $116.2 million to $310.3 million in 2021. The increase was primarily due to a full year of service to innovator customers whose products address the COVID-19 pandemic. The Company entered into most of these arrangements during the second and third quarters of 2020 and has provided services to them and new innovator customers throughout 2021.

CDMO lease revenue increased $26.9 million to $305.2 million in 2021. The increase was primarily due to a full year of service to Johnson & Johnson in 2021 as the arrangement was entered into during the second quarter of 2020. This increase was offset by a decrease from the COVID-19 development public-private partnership with BARDA of $4.7 million. This arrangement was terminated in November 2021.

Cost of Services and Gross Margin

Cost of Services increased $220.5 million to $365.5 million in 2021. The increase was primarily due to an increase in CDMO service activities at our Bayview facility. Additionally, the Company wrote-off inventory of $41.5 million and incurred remediation costs during 2021 as a result of the cross-contamination event at the Bayview facility identified during the three months ended June 30, 2021.

Services gross margin percentage decreased to 41% in 2021. The decrease was primarily due to inventory write-offs at our Bayview facility and remediation costs of our COVID-19 manufacturing activities.

Contracts and Grants

Contract and grants revenue increased $19.1 million, or 17%, to $134.2 million in 2021. The increase was primarily due to the termination of the Centers of Innovation and Advanced Development and Manufacturing ("CIADM") contract with BARDA and the recognition of $55.2 million for the release of contract liabilities offset by a decrease in developmental activities associated with the Company's COVID-HIG and AV7909 product candidates.

Principal Sources of Capital Resources

We have historically financed our operating and capital expenditures through existing cash and cash equivalents, cash from operations, development contracts and grant funding and borrowings under our senior revolving credit facility (the "Revolving Credit Facility") and senior term loan facility (the "Term Loan Facility", and together with the Revolving Credit Facility, the "Senior Secured Credit Facilities") and other lines of credit we have established from time to time. We also obtain financing from the sale of our common stock upon exercise of stock options. As of December 31, 2022, we had unrestricted cash and cash equivalents of $642.6 million and remaining capacity under our Revolving Credit Facility of $0.7 million.

Going Concern

The consolidated financial statements have been prepared on the going concern basis of accounting, which assumes the Company will continue to operate as a going concern and which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business.

As of December 31, 2022, there is $598.0 million outstanding on the our Revolving Credit Facility and $362.8 million on our Term Loan Facility that mature in October 2023, which is within one year of the date that the consolidated financial statements for the year ended December 31, 2022 are issued. The Company determined that there is substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued as a result of these pending maturities. This evaluation considered the potential mitigating effect of management’s plans that have not been fully implemented. Management may evaluate the mitigating effect of its plans to determine if it is probable that (1) the plans will be effectively implemented within one year after the date the financial statements are issued, and (2) when implemented, the plans will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern. The Company's plan to alleviate the substantial doubt includes amending its existing Senior Secured Credit Facilities that are due October 2023.

On February 14, 2023, the Company entered into a Consent, Limited Waiver, and Third Amendment to the Amended and Restated Credit Agreement (the "Credit Agreement" and “Third Credit Agreement Amendment”) relating to the Senior Secured Credit Facilities. Pursuant to the Third Credit Agreement Amendment, the requisite lenders consented to our sale of our travel health business to Bavarian Nordic substantially in accordance with the terms of the Sale Agreement. The proceeds from the transaction will be deposited into a cash collateral account with the Administrative Agent and will, unless otherwise agreed to by the Company and the requisite lenders, be used to repay the outstanding Term Loan Facility on the expiration of the Limited Waiver (as described below). We currently expect the transaction to close in the second quarter of 2023, but we can provide no assurance that the transaction will close prior to the October 2023 maturity of the Term Loan Facility, or at all.

48

Pursuant to the Third Credit Agreement Amendment the requisite lenders have agreed to a limited waiver of any defaults or events of default that result from (a) any violation of the financial covenants set forth in the Senior Secured Credit Facilities with respect to the fiscal quarters ending December 31, 2022 and March 31, 2023 and (b) the going concern qualification or exception contained in the audited financial statements for the fiscal year ending December 31, 2022. This limited waiver will expire on the earlier to occur of (i) any other event of default and (ii) April 17, 2023. During this period the Company is working with lenders under the Senior Secured Credit Facilities in connection with replacing such facilities before their October 2023 maturity with revised terms and conditions. The Company does not expect to be in compliance with debt covenants in future periods without additional sources of liquidity or future amendments to the Credit Agreement.

While the Company is in the process of replacing and expects to replace the Senior Secured Credit Facilities before they mature, management cannot make the assumption that it is probable that the Company will be able to obtain such debt refinancing on commercially reasonable terms or at all until a new credit facility is in place. The Company is currently working with its lenders to refinance the Senior Secured Credit Facilities with revised terms and conditions. The extent to which the Company will be able to affect such refinancing, replacement or maturity extension on terms that are favorable or at all is dependent on a number of uncertain factors, including then-prevailing credit and other market conditions, economic conditions, particularly in the pharmaceutical and biotechnology industry, disruptions or volatility caused by factors such as COVID-19, regional conflicts, inflation, and supply chain disruptions. In addition, rising interest rates could limit our ability to refinance the Senior Secured Credit Facilities when they mature or cause us to pay higher interest rates upon refinancing.

The Company has $642.6 million of cash on hand at December 31, 2022. On January 9, 2023, the Company announced the 2023 organizational restructuring Plan (the “Plan”) intended to reduce operating costs, improve operating margins, and continue advancing the Company’s ongoing commitment to profitable growth. The Plan includes a reduction of the Company’s current workforce by approximately five percent. These actions, in combination with other cost reduction initiatives, are expected to result in annualized savings of over $60.0 million when fully implemented.

Cash Flows

The following table provides information regarding our cash flows for the years ended December 31, 2022 and 2021.

Effect of exchange rate changes on cash, cash equivalents and restricted cash	0.5		(0.3)
Net change in cash, cash equivalents and restricted cash	$	66.3	$	(45.2)

Operating Activities:

Net cash used in operating activities of $34.1 million in 2022 was due to net income excluding non-cash items of $32.0 million offset by negative working capital changes of $2.1 million primarily due an increase in payments for our contingent consideration and other accrued expenses, an increase in prepaid expenses and an accumulation of inventory, partially offset by collections on receivables.

Net cash provided by operating activities of $320.2 million in 2021 was due to net income excluding non-cash items of $465.2 million offset by negative working capital changes of $145.0 million due to increases in receivables and associated changes in contract liabilities and the accumulation of inventory.

Net cash provided by (used in) operating activities decreased $354.3 million from 2021 to 2022. The decrease is due to a decrease in net income excluding non-cash items of $497.2 million offset by an increase in working capital changes of $142.9 million.

49

Investing Activities:

Net cash used in investing activities of $381.3 million in 2022 relates to payments for asset acquisitions, the purchases of property, plant and equipment and a royalty settlement payment.

Net cash used in investing activities of $224.1 million in 2021 relates to purchases of property, plant and equipment for increased capacity at our Rockville and Bayview facilities.

Net cash used in investing activities increased $157.2 million from 2021 to 2022. The increase is largely due the acquisition of worldwide rights to TEMBEXA® for $238.0 million, which closed in the third quarter of 2022.

Financing Activities:

Net cash provided by financing activities of $481.2 million in 2022 was largely from the $598.0 million of proceeds from our Revolving Credit Facility partially offset by repurchases of stock of $82.1 million and payments on our term loan of $33.8 million.

Net cash used in financing activities of $141.0 million in 2021 was primarily due to repurchases of stock of $106.0 million and payments on debt of $35.9 million.

Net cash provided by (used in) financing activities increased $622.2 million from 2021 to 2022. The increase is largely due to the proceeds from our Revolving Credit Facility of $598.0 million, partially offset by a decrease in cash payments on our Term Loan Facility.

Debt

As of December 31, 2022, the Company has $1.4 billion of fixed and variable rate debt with varying maturities, with $957.3 million payable within 12 months (see Note 9, "Debt" in the Notes to Consolidated Financial Statements in Part II, Item 8 of this Amendment).

Uncertainties and Trends Affecting Funding Requirements

We expect to continue to fund our anticipated operating expenses, capital expenditures and debt service requirements from the following sources:

•existing cash and cash equivalents;

•net proceeds from the sale of our products and CDMO services;

•development contracts and grant funding;

•proceeds from the sale of our travel health business to Bavarian Nordic (see Note 19, "Subsequent events" in the Notes to Consolidated Financial Statements in Part II, Item 8 of this Amendment); and

•our Senior Secured Credit Facilities and any replacement or other lines of credit we may establish from time to time.

There are numerous risks and uncertainties associated with product sales and with the development and commercialization of our product candidates. We may seek additional external financing to provide additional financial flexibility. Our future capital requirements will depend on many factors, including (but not limited to):

•the level, timing and cost of product sales and CDMO services;

•the extent to which we acquire or invest in and integrate companies, businesses, products or technologies;

•the acquisition of new facilities and capital improvements to new or existing facilities;

•the payment obligations under our indebtedness;

•the scope, progress, results and costs of our development activities;

•our ability to obtain funding from collaborative partners, government entities and non-governmental organizations for our development programs; and

•the costs of commercialization activities, including product marketing, sales and distribution.

50

If our capital resources are insufficient to meet our future capital requirements, we will need to finance our cash needs through public or private equity or debt offerings, bank loans, collaboration and licensing arrangements, cost reductions, assets sales or a combination of these options.

If we raise funds by issuing equity securities, our stockholders may experience dilution. Public or bank debt financing, if available, may involve agreements that include covenants, like those contained in our 3.875% Senior Unsecured Notes due 2028 (the "Senior Unsecured Notes") and the Senior Secured Credit Facilities, which could limit or restrict our ability to take specific actions, such as incurring additional debt, making capital expenditures, pursuing acquisition opportunities, buying back shares or declaring dividends. If we raise funds through collaboration and licensing arrangements with third parties, it may be necessary to relinquish valuable rights to our technologies or product candidates or grant licenses on terms that may not be favorable to us.

Economic conditions, including market volatility and adverse impacts on financial markets as a result of the COVID-19 pandemic, may make it more difficult to obtain financing on attractive terms, or at all. Any new debt funding, if available, may be on terms less favorable to us than our Senior Secured Credit Facilities or the Senior Unsecured Notes. If financing is unavailable or lost, our business, operating results, financial condition and cash flows would be adversely affected, and we could be forced to delay, reduce the scope of or eliminate many of our planned activities.

As of December 31, 2022, the Company had fixed lease payment obligations of $23.5 million, with $6.5 million due within 12 months. The Company has non-cancelable purchase commitments of $132.8 million, with an estimated $125.7 million being due within 12 months.

Critical Accounting Policies and Estimates

Our consolidated financial statements and related disclosures are prepared in accordance with US GAAP, which requires management to make estimates, judgments and assumptions that affect the amounts reported. Note 3, “Summary of significant accounting policies” of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Amendment describes the accounting policies and methods used in the preparation of the Company’s consolidated financial statements. Management considers an accounting policy to be critical if it is important to reporting our financial condition and results of operations, and if it requires significant judgment and estimates on the part of management in its application. Management bases its estimates on historical experience and on various other assumptions it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the reported amounts of revenues and expenses that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Management believes the Company’s critical accounting policies and estimates are those related to revenue recognition, contingent consideration, and income taxes.

Revenue Recognition

The Company's product sales are recognized at a point-in-time generally upon delivery to the customer, depending on the performance obligation which the Company is delivering. The Company's CDMO arrangements are generally recognized on a percentage of completion basis utilizing a cost-to-cost method. Revenues are recognized as a percentage of the work completed during the period in an amount that reflects the percentage of the consideration which the Company expects to receive in exchange for the product or services.

51

For contracts with multiple performance obligations, the Company allocates the contract price to each performance obligation on a relative standalone selling price basis using the Company’s best estimate of the standalone selling price of each distinct product or service in the contract. Certain contracts may include lease components which are recognized under Accounting Standards Codification ("ASC") 842. The primary method used to estimate standalone selling price is the price observed in standalone sales to customers, however when prices in standalone sales are not available the Company may use third-party pricing for similar products or services or estimate the standalone selling price based on the best available information.

Revenues are recorded net of reserves established for applicable discounts and allowances that are offered within contracts with customers. The Company makes estimates of the transaction price, including variable consideration that is subject to a constraint. Estimates of variable consideration includes allowances for returns, specialty distributor fees, wholesaler fees, prompt payment discounts, government rebates, chargebacks and rebates under managed care plans. Revenues from sales of products is recognized to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with such variable consideration is subsequently resolved. Provisions for variable consideration revenues from sales of products are recorded at the net sales price. For additional information on our revenues, refer to Note 12, "Revenue recognition" in the Notes to Consolidated Financial Statements in Part II, Item 8. of this Amendment.

Contingent Consideration

In connection with the Company's acquisitions accounted for as business combinations, the Company records contingent consideration associated with sales-based royalties, sales-based milestones and development and regulatory milestones at fair value, as applicable. The fair value model used to calculate these obligations is based on the income approach (a discounted cash flow model) that has been risk adjusted based on the probability of achievement of net sales and achievement of the milestones. The inputs the Company uses for determining the fair value of the contingent consideration associated with sales-based royalties, sales-based milestones and development and regulatory milestones are Level 3 fair value measurements. The Company re-evaluates the fair value of contingent consideration on a quarterly basis. Changes in the fair value can result from adjustments to the discount rates and updates in the assumed timing of or achievement of net sales and/or the achievement of development and regulatory milestones.

The Company's acquisitions accounted for as asset acquisitions may also include contingent consideration payments to be made for sales-based royalties, sales-based milestones and development and regulatory milestones. We assess whether such contingent consideration meets the definition of a derivative. Contingent consideration payments in an asset acquisition not required to be accounted for as derivatives are recognized when the contingency is resolved, and the consideration is paid or becomes payable. Contingent consideration payments required to be accounted for as derivatives are recorded at fair value on the date of the acquisition and are subsequently remeasured to fair value at each reporting date. For additional information on the Company's contingent consideration, refer to Note 7, "Fair value measurements" in the Notes to Consolidated Financial Statements in Part II, Item 8. of this Amendment.

Income Taxes

The Company recognizes deferred tax assets and liabilities for future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases and net operating loss and R&D tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the year in which those temporary differences are expected to be recovered or settled. Valuation allowances are recorded as appropriate to reduce deferred tax assets to the amount considered likely to be realized.

The Company’s income tax expense, deferred tax assets and liabilities and liabilities for unrecognized tax benefits reflect management’s best assessment of estimated current and future taxes to be paid. As tax laws are complex and subject to different interpretations, significant management judgement is required in (1) calculating the Company's income tax expense, deferred tax assets and deferred tax liabilities, (2) determining any valuation allowance recorded against deferred tax assets and (3) evaluating the amount of unrecognized tax benefits, as well as the interest and penalties related to such uncertain tax positions. The Company's estimates and assumptions may differ from tax benefits ultimately realized. For additional information on the Company's income taxes, refer to Note 14, "Income taxes" in the Notes to Consolidated Financial Statements in Part II, Item 8. of this Amendment.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Emergent BioSolutions Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Emergent BioSolutions Inc. and subsidiaries (the Company) as of December 31, 2022 and 2021, the related consolidated statements of operations, comprehensive income (loss), changes in stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2022, and the related notes and financial statement schedule listed in the Index at Item 15 (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated March 1, 2023, except for the effect of the material weakness in controls related to the state income tax process described in the second and third paragraphs of that report as to which the date is December 11, 2023, expressed an adverse opinion thereon.

Restatement of 2022 Financial Statements

As discussed in Note 2, "Restatement of consolidated financial statements", the 2022 consolidated financial statements have been restated to correct a misstatement related to income taxes.

The Company's Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 3 to the financial statements, the Company does not expect to be in compliance with debt covenants in future periods without additional sources of liquidity or future amendments to its Credit Agreement, has a working capital deficiency, and has stated that substantial doubt exists about the Company’s ability to continue as a going concern. Management's evaluation of the events and conditions and management’s plans regarding these matters are also described in Note 3. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

53

	Revenue recognition
Description of the Matter	As described in Notes 3 and 12 to the consolidated financial statements, the Company recognized revenues of $373.7 million for the year ended December 31, 2022 related to the sale of nasal naloxone products. For these product sales, revenue is recognized at a point in time, and the Company’s estimation of variable consideration includes allowances for returns, certain fees, discounts, rebates and chargebacks. Auditing revenue recognition for nasal naloxone product sales involved significant auditor judgment because it involves subjective assumptions and estimates made by management. For example, auditing management’s estimated rebates and returns for commercial arrangements are subject to significant judgment because their expected value is based on assumptions including sales or invoice data, expected utilization rates, historical payment experience, and changes in product pricing or customer contracts. These estimates are forward-looking and could be affected by future economic conditions and the competitive environment.
How We Addressed the Matter in Our Audit	We obtained an understanding, evaluated the design, and tested the operating effectiveness of controls over the Company’s revenue recognition for nasal naloxone product sales. For example, we tested controls over management’s review over the assumptions used in the estimation of the rebates and returns. We also tested management’s controls over the completeness and accuracy of the data used in the underlying calculations. To test revenue recognized, our audit procedures included the following primary procedures, amongst others. We estimated the rebates and returns accrual using the Company’s historical data as well as externally available information and compared the result to the Company’s estimated rebates and returns accrual. We evaluated the Company’s ability to accurately estimate the accrual for rebates by comparing historically recorded accruals to the actual amount that was ultimately paid by the Company.
	Evaluation of Goodwill for impairment
Description of the Matter	As of December 31, 2022, the Company’s goodwill balance was $218.2 million. As discussed in Notes 3 and 6 of the consolidated financial statements, goodwill is tested annually for impairment at the reporting unit level. The Company evaluated goodwill for impairment as of October 1, 2022 using an income based (discounted cash flows) approach. As a result of the Company's annual goodwill impairment test, the Company recorded a $6.7 million goodwill impairment charge related to the CDMO – Services reporting unit of the Services reporting segment, which is included in "Goodwill impairment" in the Consolidated Statement of Operations for the year ended December 31, 2022. Auditing management’s goodwill impairment tests involved a high degree of auditor judgment due to the significant estimation required to determine the fair value of each reporting unit. In particular, the fair value estimate for certain reporting units was sensitive to significant assumptions such as the determination of guideline companies, discount rate, revenue growth rates and operating margins used to estimate future cash flows, which are affected by expectations about future market or economic conditions.
How We Addressed the Matter in Our Audit	We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company’s goodwill impairment evaluation process. For example, we tested controls over management’s review of the data used in their valuation models and reviewed significant assumptions discussed above used in determining the reporting unit fair values. To test the estimated fair value of the Company’s reporting units, with the assistance of our valuation professionals, our audit procedures included, among others, assessing fair value methodologies and testing the significant assumptions discussed above. We compared the significant assumptions used by management to current industry and economic trends, the Company’s historical trends with consideration given to changes in the Company’s business, customer base or product mix and other relevant factors. We assessed the historical accuracy of management’s estimates and performed sensitivity analyses of significant assumptions to evaluate the changes in the fair value of the reporting units that would result from changes in the assumptions. We also evaluated the reconciliation of the estimated aggregate fair value of the reporting units to the Company’s market capitalization.

We have served as the Company’s auditor since 2004.

1. Nature of the business and organization

Organization and business

Emergent BioSolutions Inc. (“Emergent,” the “Company,” “we,” “us,” and “our”) is a global life sciences company focused on providing innovative preparedness and response solutions addressing accidental, deliberate, and naturally occurring Public Health Threats ("PHTs"). The Company's solutions include a product portfolio, a product development portfolio, and a contract development and manufacturing ("CDMO") services portfolio.

The Company is focused on the following five PHT categories: chemical, biological, radiological, nuclear and explosives ("CBRNE"); emerging infectious diseases ("EID"); travel health; emerging health crises; and acute/emergency care.

Asset Acquisition

During the year ended December 31, 2022, the Company acquired from Chimerix ("the Seller") the exclusive worldwide rights to brincidofovir, including TEMBEXA® and related assets (the “Transaction”). TEMBEXA is an oral antiviral medical countermeasure to treat smallpox approved by the FDA in June 2021. Under the terms of the Asset Purchase Agreement (the "Purchase Agreement"), the Company paid $238.0 million upon closing of the Transaction, and is subject to potential milestone payments of up to $124.0 million contingent on the potential exercise by the USG of procurement options. The closing payment and the milestone payments were based on the actual procurement value of the procurement contract (the "BARDA Contract") with the Biomedical Advanced Research and Development Authority (“BARDA”). Each milestone payment is associated with the exercise of future BARDA procurement options of TEMBEXA following the BARDA Contract base period. The Seller is also eligible to receive up to $12.5 million in regulatory milestones associated with the SymBio Pharmaceuticals Ltd. brincidofovir licensing arrangements assumed by the Company in the Transaction. The milestone payments will be recorded when the associated procurement options have been exercised and/or the regulatory milestones have been met and the consideration is paid or becomes payable. The total consideration paid in the Transaction was allocated based on the proportionate fair value of the assets acquired. We recorded $156.9 million in intangible assets, net and $82.3 million in inventories, net upon execution of the Transaction on our consolidate balance sheet.

The Seller may also earn a 20% royalty on future gross profit of TEMBEXA in the United States associated with volumes above 1.7 million treatment courses of therapy during the exclusivity period of TEMBEXA. Outside of the United States, the Purchase Agreement also allows the Seller to earn a 15% royalty on all gross profit associated with TEMBEXA sales during the exclusivity period of TEMBEXA on a market-to-market basis. Refer to Note 6 "Intangible assets and goodwill" for additional information around the impacts of this asset acquisition on the current period results.

2. Restatement of consolidated financial statements

As part of the Company's quarterly review process related to the preparation of its unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2023, the Company determined that its net state deferred tax liability was overstated as of December 31, 2022, resulting in an understatement of the income tax benefits reflected on the Company's consolidated statement of operations. This material error was associated with the use of incorrect state tax rates in the calculation of state deferred tax assets and related valuation allowances, which are non-cash items that resulted in an understatement of the Company's income tax benefit of $11.7 million for the year ended December 31, 2022. In connection with the restatement to correct this material error, the Company determined that it is appropriate to revise the financial statements as of and for the years ending December 31, 2022, 2021 and 2020 included in this Form 10-K/A to correct other unrelated immaterial errors that were previously either unrecorded or recorded as out-of-period adjustments.

The following tables present the impact of the financial statement adjustments on the Company's previously reported consolidated financial statements for the fiscal years ended December 31, 2022, 2021 and 2020. The "Previously Reported" amounts in the following tables are amounts derived from the Original Form 10-K filed with the United States Securities and Exchange Commission on March 1, 2023. The amounts in the columns labeled "Tax Adjustments" represent the effect of adjustments resulting from the correction of the overstatement of the Company's net state deferred tax liability and understatement of the income tax benefits of $11.7 million and the tax impact of all other individually immaterial non-tax adjustments of $2.2 million for the year ended December 31, 2022. The amounts in the columns labeled "Other Adjustments" represent the effect of other adjustments that relate to other unrelated errors in previously filed financial statements that were not material, individually or in the aggregate, to those filed financial statements. The effects of both the restatement for the Tax Adjustments and the revisions for the Other Adjustments have been corrected in all impacted tables and footnotes throughout these consolidated financial statements.

3. Summary of significant accounting policies

Basis of presentation and consolidation

Our financial statements are prepared in conformity with U.S. generally accepted accounting principles ("GAAP"). The accompanying consolidated financial statements include the accounts of Emergent and its wholly owned subsidiaries. All significant inter-company accounts and transactions have been eliminated in consolidation. Reclassifications of certain prior period amounts have been made to conform to the current period presentation.

During the year ended December 31, 2022, the Company revised the reporting that the chief operating decision maker (the "CODM") reviews in order to assess Company performance. The CODM manages the business with a focus on two reportable segments: (1) Products segment consisting of Government - MCM and Commercial products and (2) Services segment focused on CDMO services.

Going Concern

The consolidated financial statements have been prepared on the going concern basis of accounting, which assumes the Company will continue to operate as a going concern and which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business.

As of December 31, 2022, there is $598.0 million outstanding on the our senior revolving credit facility ("Revolving Credit Facility") and $362.8 million on our senior term loan facility ("Term Loan Facility" and together with the Revolving Credit Facility, the "Senior Secured Credit Facilities") that mature in October 2023, which is within one year of the date that the consolidated financial statements for the year ended December 31, 2022 are issued. The Company determined that there is substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are issued as a result of these pending maturities. This evaluation considered the potential mitigating effect of management’s plans that have not been fully implemented. Management evaluated the mitigating effect of its plans to determine if it is probable that (1) the plans will be effectively implemented within one year after the date the financial statements are issued, and (2) when implemented, the plans will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern. The Company's plan to alleviate the substantial doubt includes amending its existing Senior Secured Credit Facilities that are due October 2023.

On February 14, 2023, the Company entered into a Consent, Limited Waiver, and Third Amendment to the Amended and Restated Credit Agreement (the “Third Credit Agreement Amendment”, "Credit Agreement" and as amended, the "Amended Credit Agreement") relating to the Senior Secured Credit Facilities. Pursuant to the Third Credit Agreement Amendment, the requisite lenders consented to our sale of our travel health business to Bavarian Nordic substantially in accordance with the terms of the Sale Agreement. The proceeds from the transaction will be deposited into a cash collateral account with the Administrative Agent and will, unless otherwise agreed to by the Company and the requisite lenders, be used to repay the outstanding Term Loan Facility on the expiration of the Limited Waiver (as described below). We currently expect the transaction to close in the second quarter of 2023, but we can provide no assurance that the transaction will close prior to the October 2023 maturity of the Term Loan Facility, or at all.

Pursuant to the Third Credit Agreement Amendment the requisite lenders have agreed to a limited waiver of any defaults or events of default that result from (a) any violation of the financial covenants set forth in the Senior Secured Credit Facilities with respect to the fiscal quarters ending December 31, 2022 and March 31, 2023 and (b) the going concern qualification or exception contained in the audited financial statements for the fiscal year ending December 31, 2022. This limited waiver will expire on the earlier to occur of (i) any other event of default and (ii) April 17, 2023. During this period the Company is working with lenders under the Senior Secured Credit Facilities in connection with replacing such facilities before their October 2023 maturity with revised terms and conditions. The Company does not expect to be in compliance with debt covenants in future periods without additional sources of liquidity or future amendments to the Credit Agreement.

69

While the Company is in the process of replacing and expects to replace the Senior Secured Credit Facilities before they mature, management cannot conclude that it is probable that the Company will be able to obtain such debt refinancing on commercially reasonable terms or at all until a new credit facility is in place. The Company is currently working with its lenders to refinance the Senior Secured Credit Facilities with revised terms and conditions. The extent to which the Company will be able to affect such refinancing, replacement or maturity extension on terms that are favorable or at all is dependent on a number of uncertain factors, including then-prevailing credit and other market conditions, economic conditions, particularly in the pharmaceutical and biotechnology industry, disruptions or volatility caused by factors such as COVID-19, regional conflicts, inflation, and supply chain disruptions. In addition, rising interest rates could limit our ability to refinance the Senior Secured Credit Facilities when they mature or cause us to pay higher interest rates upon refinancing.

The Company has $642.6 million of cash on hand at December 31, 2022. On January 9, 2023, the Company announced the 2023 organizational restructuring Plan (the “Plan”) intended to reduce operating costs, improve operating margins, and continue advancing the Company’s ongoing commitment to profitable growth. The Plan includes a reduction of the Company’s current workforce by approximately five percent.

Use of estimates

The preparation of financial statements requires management to make estimates, judgments and assumptions that affect reported amounts and disclosures for asset impairments, revenue recognition, allowances for doubtful accounts, inventory, depreciation and amortization, business combinations, contingent consideration, stock-based compensation, income taxes, and other contingencies. Management continually re-evaluates its estimates, judgments and assumptions. These estimates are sometimes complex, sensitive to changes in assumptions and require fair value determinations using Level 3 fair value measurements. Actual results may differ materially from those estimates.

Cash, cash equivalents and restricted cash

Cash equivalents are highly liquid investments with a maturity of 90 days or less at the date of purchase and consist of time deposits and investments in money market funds with commercial banks and financial institutions. Also, the Company maintains cash balances with financial institutions in excess of insured limits. Restricted cash includes cash that is not readily available for use in the Company's operating activities. Restricted cash is primarily comprised of cash pledged under letters of credit.

Fair value measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability, an exit price, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value include:

Level 1 —	Observable inputs for identical assets or liabilities such as quoted prices in active markets;
Level 2 —	Inputs other than quoted prices in active markets that are either directly or indirectly observable; and
Level 3 —	Unobservable inputs in which little or no market data exists, which are therefore developed by the Company using estimates and assumptions that reflect those that a market participant would use.

On a recurring basis, the Company measures and records money market funds (Level 1), interest-rate swap arrangements and time deposits (Level 2) and contingent purchase consideration (Level 3) using fair value measurements in the accompanying financial statements. The carrying amounts of the Company's short-term financial instruments, which include cash and cash equivalents, accounts receivable and accounts payable approximate their fair values due to their short maturities. The carrying amounts of the Company’s long-term variable interest rate debt arrangements (Level 2) approximate their fair values.

70

Significant customers and accounts receivable

Billed accounts receivable are stated at invoice amounts and consist of amounts due from the USG, commercial CDMO customers, as well as amounts due under reimbursement contracts with other government entities and non-government organizations. The Company's branded and generic opioid overdose reversal product is sold commercially through physician-directed or standing order prescriptions at retail pharmacies, as well as state health departments, law enforcement agencies, state and local community based organizations, substance abuse centers and federal agencies. If necessary, the Company records a reserve for credit losses to allow for amounts which may be unrecoverable. This provision is based upon an analysis of the Company's prior collection experience, customer creditworthiness and current economic trends. Amounts determined to be uncollectible are charged or written-off against the reserve. Unbilled accounts receivable relates to various service contracts for which work has been performed and the Company has a right to bill but invoicing has not yet occurred. Contract assets include revenues recognized in advance of billings and the Company does not have a right to invoice the customer under the terms of the contract. The Company has receivables from contracts containing lease components. At each reporting period, the Company assesses whether it is probable that the Company will collect all future lease payments. The Company considers payment history and current credit status when assessing collectability. The Company does not adjust our receivables for the effects of a significant financing component at contract inception if we expect to collect the receivables in one year or less from the time of sale.

Concentration Risk

Customers

The Company has long-term contracts with the USG that expire at various times from 2023 through 2036. The Company has derived a significant portion of its revenue from sales of our Government - MCM products under contracts with the USG. The Company's current USG contracts do not necessarily increase the likelihood that it will secure future comparable contracts with the USG. The Company expects that a significant portion of the business will continue to be under government contracts that present a number of risks that are not typically present in the commercial contracting process. USG contracts for ACAM2000 and Anthrax Vaccines and other medical countermeasures products are subject to unilateral termination or modification by the government. The Company may fail to achieve significant sales of its medical countermeasures products, including ACAM2000 and Anthrax Vaccines to customers in addition to the USG, which would harm their growth opportunities. The Company's other product sales, largely Nasal Naloxone Products, are largely sold commercially through physician-directed or standing order prescriptions at retail pharmacies, as well as to state health departments, local law enforcement agencies, community-based organizations, substance abuse centers and other federal agencies. In 2022, we filed our supplemental New Drug Application for NARCAN® (naloxone HCI) Nasal Spray, as an over-the-counter emergency treatment which if approved would further broaden our customer base. Our CDMO customers are generally third-party pharmaceutical companies. Refer to Footnote 12, "Revenue recognition" for more information regarding significant customers.

Although the Company seeks to expand its customer base and to renew its agreements with its customers prior to expiration of a contract, a delay in securing a renewal or a failure to secure a renewal or securing a renewal on less favorable terms may have a material adverse effect on the Company’s financial condition and results of operations.

The Company’s accounts receivable do not represent a significant concentration of credit risk. The USG accounted for approximately 43%, 51% and 62% of total revenues for 2022, 2021 and 2020, respectively. The Company’s accounts receivable as of December 31, 2022 and 2021, consist primarily of amounts due from the USG or other large multi-national highly reputable customers for product sales, CDMO services or from government agencies under government grants. Management does not deem credit risk to be significant.

Financial Institutions

Cash and cash equivalents are maintained with several financial institutions. The Company has deposits held with banks that exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions of reputable credit and, therefore, bear minimal credit risk.

71

Lender Counterparties

There is lender counterparty risk associated with the Company's revolving credit facility and derivatives instruments. There is risk that the Company’s revolving credit facility investors and derivative counterparties will not be available to fund as obligated. If funding under the revolving credit facility is unavailable, the Company may have to acquire a replacement credit facility from different counterparties at a higher cost or may be unable to find a suitable replacement. The Company seeks to manage risks from its revolving credit facility and derivative instruments by contracting with experienced large financial institutions and monitoring the credit quality of its lenders. As of December 31, 2022, the Company does not anticipate nonperformance by any of its counterparties.

Inventories, net

Inventories are stated at the lower of cost or net realizable value with cost being determined using a standard cost method, which approximates average cost. Average cost consists primarily of material, labor and manufacturing overhead expenses (including fixed production-overhead costs) and includes the services and products of third-party suppliers. The Company analyzes its inventory levels quarterly and writes down, in the applicable period, inventory that has become obsolete, inventory that has a cost basis in excess of its expected net realizable value and inventory in excess of expected customer demand. The Company also writes off, in the applicable period, the costs related to short-dated, contaminated or expired inventory. Costs of purchased inventories are recorded using weighted-average costing. The Company determines normal capacity for each production facility and allocates fixed production-overhead costs on that basis.

The Company records inventory acquired in business combinations utilizing the comparative sales method, which estimates the expected sales price reduced for all costs expected to be incurred to complete/dispose of the inventory with a profit on those costs.

Property, plant and equipment, net

Property, plant and equipment are stated at cost less accumulated depreciation and impairments. subject to reviews for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. The cost of normal, recurring or periodic repairs and maintenance activities related to property, plant and equipment are expensed as incurred. The cost for planned major maintenance activities, including the related acquisition or construction of assets, is capitalized if the repair will result in future economic benefits.

Interest costs incurred during the construction of major capital projects are capitalized until the underlying asset is ready for its intended use, at which point the interest costs are amortized as depreciation expense over the life of the underlying asset.

The Company capitalizes internal-use software when both (a) the software is internally developed, acquired, or modified solely to meet the entity’s internal needs and (b) during the software’s development or modification, no substantive plan either exists or is being developed to market the software externally. Capitalization of qualifying internal-use software costs begins when the preliminary project stage is completed, management with the relevant authority, implicitly or explicitly, authorizes and commits to the funding of the software project, and it is probable that the project will be completed and the software will be used to perform the function intended.

The Company generally depreciates or amortizes the cost of its property, plant and equipment using the straight-line method over the estimated useful lives of the respective assets, which are summarized as follows:

Land	Not depreciated
Buildings	31-39 years
Building improvements	10-39 years
Furniture and equipment	3-15 years
Software	3-7 years
Leasehold improvements	Lesser of the asset life or lease term

Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is credited or charged to operations. Repairs and maintenance costs are expensed as incurred.

72

The Company determines the fair value of the property, plant and equipment acquired in a business combination utilizing either the cost approach or the sales comparison approach. The cost approach is determined by establishing replacement cost of the asset and then subtracting any value that has been lost due to economic obsolescence, functional obsolescence, or physical deterioration. The sales comparison approach determines an asset is equal to the market price of an asset of comparable features such as design, location, size, construction, materials, use, capacity, specification, operational characteristics and other features or descriptions.

Income taxes

Income taxes includes federal, state, local and foreign taxes. Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax basis and net operating loss and research and development ("R&D") tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the year in which those temporary differences are expected to be recovered or settled. Valuation allowances are recorded as appropriate to reduce deferred tax assets to the amount considered likely to be realized.

Deferred income tax effects of transactions reported in different periods for financial reporting and income tax return purposes are recognized under the asset and liability method of accounting for income taxes. This method gives consideration to the future tax consequences of the deferred income tax items and immediately recognizes changes in income tax laws in the year of enactment.

The Company's ability to realize deferred tax assets depends upon future taxable income as well as the limitations discussed below. For financial reporting purposes, a deferred tax asset must be reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized prior to expiration. The Company considers future taxable income and ongoing tax planning strategies in assessing the need for valuation allowances. In general, if the Company determines that it is more likely than not to realize more than the recorded amounts of net deferred tax assets in the future, the Company will reverse all or a portion of the valuation allowance established against its deferred tax assets, resulting in a decrease to income taxes in the period in which the determination is made. Likewise, if the Company determines that it is not more likely than not to realize all or part of the net deferred tax asset in the future, the Company will establish a valuation allowance against deferred tax assets, with an offsetting increase to income taxes, in the period in which the determination is made.

Under sections 382 and 383 of the Internal Revenue Code, if an ownership change occurs with respect to a "loss corporation", as defined therein, there are annual limitations on the amount of net operating losses and deductions that are available. The Company has recognized the portion of net operating losses and R&D tax credits acquired that will not be limited and are more likely than not to be realized.

Because tax laws are complex and subject to different interpretations, significant judgment is required. As a result, the Company makes certain estimates and assumptions, in (1) calculating the Company's income tax expense, deferred tax assets and deferred tax liabilities, (2) determining any valuation allowance recorded against deferred tax assets and (3) evaluating the amount of unrecognized tax benefits, as well as the interest and penalties related to such uncertain tax positions. The Company's estimates and assumptions may differ from tax benefits ultimately realized.

Asset Impairment Analysis

Goodwill and Indefinite-lived Intangible Assets

Goodwill represents the difference between the purchase price and the fair value of the identifiable tangible and intangible net assets when accounted for using the purchase method of accounting. Goodwill is not amortized but is reviewed for impairment. Goodwill is allocated to the Company's reporting units, which are components of our business for which discrete cash flow information is available one level below its operating segment. The Company evaluates goodwill and other indefinite-lived intangible assets for impairment annually as of October 1 and at interim if an event or other circumstance indicates that we may not recover the carrying value of the asset. If the Company believes that as a result of its qualitative assessment it is more likely than not that the fair value of a reporting unit or other indefinite-lived intangible asset is greater than its carrying amount, the quantitative impairment test is not required. If however it is determined that it is not more likely than not that the fair value of a reporting unit or other indefinite-lived intangible asset is greater than its carrying amount, a quantitative test is required.

73

The quantitative goodwill impairment test is performed using a one-step process. The process is to compare the fair value of a reporting unit with its carrying amount. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired. If the carrying amount of a reporting unit exceeds its fair value, goodwill of the reporting unit is impaired and an impairment loss is recognized in an amount equal to that excess up to the total amount of goodwill included in the reporting unit.

When the Company has material indefinite lived intangible assets associated with in-process research and development ("IPR&D") a qualitative assessment is performed. If the qualitative assessment indicates that it is not more likely than not that the fair value of the indefinite lived intangible asset exceeds its carrying amount, the Company compares the estimated fair value of the intangible with its carrying value. If the carrying value of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Determining fair value requires the exercise of judgment about appropriate discount rates, perpetual growth rates and the amount and timing of expected future cash flows (see Note 6, "Intangible assets and goodwill").

Long-lived Assets

Long-lived assets such as intangible assets and property, plant and equipment are not required to be tested for impairment annually. Instead, they are tested for impairment whenever circumstances indicate that the carrying amount of the asset may not be recoverable, such as when the disposal of such assets is likely or there is an adverse change in the market involving the business employing the related assets. If an impairment analysis is required, the impairment test employed is based on whether the Company’s intent is to hold the asset for continued use or to hold the asset for sale. If the intent is to hold the asset for continued use, the impairment test first requires a comparison of undiscounted future cash flows to the carrying value of the asset. If the carrying value of the asset exceeds the undiscounted cash flows, the asset would not be deemed to be recoverable. Impairment would then be measured as the excess of the asset’s carrying value over its fair value. Fair value is typically determined by discounting the future cash flows associated with that asset. If the intent is to hold the asset for sale and certain other criteria are met, the impairment test involves comparing the asset’s carrying value to its fair value less costs to sell. To the extent the carrying value is greater than the asset’s fair value less costs to sell, an impairment loss is recognized in an amount equal to the difference. Significant judgments used for long-lived asset impairment assessments include identifying the appropriate asset groupings and primary assets within those groupings, determining whether events or circumstances indicate that the carrying amount of the asset may not be recoverable, determining the future cash flows for the assets involved and assumptions applied in determining fair value, which include, reasonable discount rates, growth rates, market risk premiums and other assumptions about the economic environment.

Contingent Consideration

In connection with the Company's acquisitions accounted for as business combinations, the Company records contingent consideration associated with sales-based royalties, sales-based milestones and development and regulatory milestones at fair value. The fair value model used to calculate these obligations is based on the income approach (a discounted cash flow model) that has been risk adjusted based on the probability of achievement of net sales and achievement of the milestones. The inputs the Company uses for determining the fair value of the contingent consideration associated with sales-based royalties, sales-based milestones and development and regulatory milestones are Level 3 fair value measurements. The Company re-evaluates the fair value on a quarterly basis. Changes in the fair value can result from adjustments to the discount rates and updates in the assumed timing of or achievement of net sales and/or the achievement of development and regulatory milestones. Any future increase or decrease in the fair value of the contingent consideration associated with sales-based royalties and sales-based milestones along with development and regulatory milestones are based on an assessment of the likelihood that the underlying net sales or milestones will be achieved.

The associated payments which will become due and payable for sales-based royalties and milestones result in a charge to cost of product sales in the period in which the increase is determined. Similarly, any future decrease in the fair value of contingent consideration associated with sales-based royalties and sales-based milestones will result in a reduction in cost of product sales. The changes in fair value for potential future sales-based royalties associated with product candidates in development will result in a charge to cost of product sales in the period in which the increase is determined.

The Company's acquisitions accounted for as asset acquisitions may also include contingent consideration payments to be made for sales-based royalties, sales-based milestones and development and regulatory milestones. The Company assesses whether such contingent consideration meets the definition of a derivative. Contingent consideration payments in an asset acquisition not required to be accounted for as derivatives are recognized when the contingency is resolved, and the consideration is paid or becomes payable. Contingent consideration payments required to be accounted for as derivatives are recorded at fair value on the date of the acquisition and are subsequently remeasured to fair value at each reporting date.

74

Leases

The Company has operating leases for corporate offices, R&D facilities and manufacturing facilities. The Company determines if an arrangement is a lease at inception. Operating leases with future minimum lease payments in excess of 12 months and total lease payments greater than $0.4 million are included in right-of-use (ROU) assets and liabilities. The Company has elected to record expense on a cash basis for leases with minimum lease payments of 12 months or less and/or total lease payments less $0.4 million.

ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of the Company's leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The Company uses an implicit rate when readily determinable. At the beginning of a lease, the operating lease ROU asset also includes any concentrated lease payments expected to be paid and excludes lease incentives. The Company's lease ROU asset may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise those options.

Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are accounted for separately.

Revenue recognition

The Company recognizes revenue when the Company's customers obtain control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services by analyzing the following five steps: (1) identify the contract with a customer(s); (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies a performance obligation.

Multiple performance obligations

At contract inception, the Company assesses the products or services promised in a contract and identifies a performance obligation for each promise to transfer to the customer a product or service that is distinct, including evaluating whether the contract includes a customer option for additional goods or services which could represent a material right. A performance obligation is a promise in a contract to transfer a distinct product or service to a customer and is the unit of account under ASC 606. Contracts sometimes include more than one product, a lease, or options for customers to purchase additional products or services in the future for free or at a discount, which gives rise to separate performance obligations. For contracts with multiple performance obligations, the Company allocates the contract price to each performance obligation on a relative standalone selling price basis using the Company’s best estimate of the standalone selling price of each distinct product or service in the contract. The primary method used to estimate standalone selling price is the price observed in standalone sales to customers, however when prices in standalone sales are not available the Company may use third-party pricing for similar products or services or estimate the standalone selling price. Allocation of the transaction price is determined at the contracts’ inception.

Transaction price and variable consideration

Once the performance obligations in the contract have been identified, the Company estimates the transaction price of the contract. The estimate includes amounts that are fixed as well as those that can vary based on expected outcomes of the activities or contractual terms. The Company's variable consideration includes net profit received from sales of the Company's generic Nasal naloxone product, certain products sold on a net basis, cost-plus-fee contract terms and consideration transferred under its development contracts as consideration received can vary based on developmental progression of the product candidate. When a contract's transaction price includes variable consideration, the Company evaluates the variable consideration to determine whether the estimate needs to be constrained; therefore, the Company includes the variable consideration in the transaction price only to the extent that it is probable that a significant reversal of the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Variable consideration estimates are updated at each reporting date. There were no significant constraints or material changes to the Company's variable consideration estimates as of or during the year ended December 31, 2022.

75

Product sales

For our product sales, we recognize revenue at a point in time when the Company’s performance obligations have been satisfied and control of the products transfer to the customer. To indicate the transfer of control the Company will have a present right to payment, legal title must have passed to the customer, and the customer must have the significant risks and rewards of ownership. This point in time depends on several factors, including delivery, transfer of legal title, transition of risk and rewards of the product to the customer and the Company's right to payment.

The Company's contracts for the sale of the Company's Government - MCM products include certain acceptance criteria before title passes to the customer. The primary customer for the Company's Government - MCM products and the primary source of funding for the development of its MCM product candidate portfolio is the USG. The USG contracts for the sale of the Company's Government - MCM products are normally multi-year contracts with annual options.

For the Company’s commercial products, upon transfer of control of the goods the Company reflects estimates of the consideration that the Company expects. Prior to recognizing revenue, the Company makes estimates of the transaction price, including variable consideration that is subject to a constraint. Estimates of variable consideration include allowances for returns, specialty distributor fees, wholesaler fees, prompt payment discounts, government rebates, chargebacks and rebates under managed care plans.

Revenue is recognized to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with such variable consideration is subsequently resolved. Provisions for variable consideration revenues from sales of products are recorded at the net sales price. Calculating certain of these provisions involves estimates and judgments and the Company determines their expected value based on sales or invoice data, contractual terms, historical utilization rates, new information regarding changes in these programs’ regulations and guidelines that would impact the amount of the actual rebates, the Company's expectations regarding future utilization rates for these programs and channel inventory data. These provisions reflect the Company's best estimate of the amount of consideration to which the Company is entitled based on the terms of the contract. The Company reassesses the Company's provisions for variable consideration at each reporting date.

CDMO services

The Company performs CDMO services for third parties. Under these contracts, activities can include drug substance and drug product manufacturing services for injectable and other sterile products, and development services such as pharmaceutical product process development, process design, technology transfer, manufacturing validations, laboratory analytical development support, aseptic filling, lyophilization, final packaging, stability studies, and suite-reservations. These contracts vary in duration, activities, and number of performance obligations. Performance obligations identified under these arrangements may include drug substance and/or drug product manufacturing, technology transfer activities, and suite-reservations.

Drug substance, drug product manufacturing, development services and technology transfer performance obligations are recognized as revenue over-time because the Company’s performance does not create an asset with an alternative use and the Company has an enforceable right to payment for performance completed as work is performed. In drug product arrangements, the customer typically owns and supplies the active pharmaceutical ingredient (API), that is used in the manufacturing process; in drug substance arrangements, the customer provides certain seed material that is used in the manufacturing process. The transaction price generally contains both a fixed and variable component. The fixed component is stated in the agreement as a fixed price per unit with no contractual provision for a refund or price concession and the variable component generally results from pass-through costs that are billed at cost-plus over the life of the contract. The Company uses an input method to measure progress toward the satisfaction of the related performance obligations based on costs incurred as a percentage of total costs to complete which the Company believes best depicts the transfer of control of goods or services promised to its customers.

Suite reservations are classified as leases when the customer directs the use of the identified suite and obtains substantially all the economic benefits from the manufacturing capacity. If a customer reserves more than one suite, the allocation of contract value is based on relative selling price which varies due to size, location, capacity, production capability for drug product or drug substance, and the time of planned use. The associated revenue is recognized on a straight-line basis over the period of performance. For arrangements that contain both lease and non-lease components, consideration in the contract is allocated on a relative standalone selling price basis.

The Company’s CDMO customer contracts generally include provisions entitling the Company to a termination penalty when the contract is terminated prior to the contract’s nominal end date. The termination penalties in the customer contracts vary but are generally considered substantive for accounting purposes and create enforceable rights and obligations throughout the stated duration of the contract. The Company accounts for a contract cancellation as a contract

modification. The determination of the contract termination penalty is based on the terms stated in the related customer agreement. As of the modification date, the Company updates its estimate of the transaction price, subject to constraints, and recognizes the amount over the remaining performance period or measure of progress under the arrangement.

For contracts that contain lease components, the Company assesses the collectability of the lease payments. If the collectability of the lease payments is probable, the Company recognizes lease income over the term of the lease on a straight-line basis. If collectability is not deemed probable at any time during the term of the lease, the Company’s lease income is limited to the lesser of (i) the lease payments that have been collected from the lessee, or the straight-line recognition of the contract value. If the collectability assessment changes to probable after the Company has determined collectability is not deemed probable, any difference between the lease income that would have been recognized if collectability had always been assessed as probable and the lease income recognized to date is recognized as a current-period adjustment to lease income. Changes to the collectability of operating leases are recorded as adjustments to lease income in the consolidated statements of operations in the period that they occur.

Contracts and grants

The Company generates contract and grant revenue primarily from cost-plus-fee contracts associated with development of certain product candidates. Revenues from reimbursable contracts are recognized as costs are incurred, generally based on allowable costs incurred during the period, plus any recognizable earned fee. The Company uses this input method to measure progress as the customer has access to the development research under these projects and benefits incrementally as R&D activities occur. When applicable, the Company considers fixed fees under cost-plus-fee contracts to be earned in proportion to the allowable costs incurred in performance of the contract, the cost-to-cost measure of progress. The Company analyzes costs for contracts and reimbursable grants to ensure reporting of revenues gross versus net is appropriate. The USG contracts for the development of the Company's MCM product candidates are normally multi-year contracts.

Research and development

The Company expenses R&D costs as incurred. The Company's R&D expenses consist primarily of:

▪personnel-related expenses;

▪fees to professional service providers for, among other things, analytical testing, independent monitoring or other administration of the Company's clinical trials and obtaining and evaluating data from the Company's clinical trials and non-clinical studies;

▪costs of CDMO services for clinical trial material; and

▪costs of materials intended for use and used in clinical trials and R&D.

Comprehensive income (loss)

Comprehensive income (loss) is comprised of net income (loss) and other changes in equity that are excluded from net income (loss). The Company includes translation gains and losses incurred when converting its subsidiaries' financial statements from their functional currency to the U.S. dollar in accumulated other comprehensive income (loss) as well as gains and losses on its pension benefit obligation and derivative instruments.

Translation and Remeasurement of Foreign Currencies

For our non-U.S. subsidiaries that transact in a functional currency other than the U.S. dollar, assets and liabilities are translated at current rates of exchange at the balance sheet date. Income and expense items are translated at the average foreign currency exchange rates for the period. Adjustments resulting from the translation of the financial statements of our foreign operations into U.S. dollars are excluded from the determination of net income (loss) and are recorded in accumulated other comprehensive income (loss), a separate component of equity. For subsidiaries where the functional currency of the assets and liabilities differ from the local currency, non-monetary assets and liabilities are remeasured at the rate of exchange in effect on the date assets were acquired while monetary assets and liabilities are remeasured at current rates of exchange as of the balance sheet date. Income and expense items are remeasured at the average foreign currency rates for the period. Remeasurement adjustments of these subsidiaries are included in other income (expense), net in our consolidated statements of operations.

77

Net income (loss) per common share

Basic net income (loss) per common share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per common share is computed using the treasury method by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period, adjusted for the potential dilutive effect of other securities if such securities were converted or exercised and are not anti-dilutive.

Treasury stock

When stock is acquired for purposes other than formal or constructive retirement, the purchase price of the acquired stock is recorded in a separate treasury stock account, which is separately reported as a reduction of equity.

When stock is retired or purchased for formal or constructive retirement, the purchase price is initially recorded as a reduction to the par value of the shares repurchased, with any excess purchase price over par value recorded as a reduction to additional paid-in capital related to the series of shares repurchased and any remainder excess purchase price recorded as a reduction to retained earnings. If the purchase price exceeds the amounts allocated to par value and additional paid-in capital related to the series of shares repurchased and retained earnings, the remainder is allocated to additional paid-in capital related to other series of shares.

To determine the cost of treasury stock that is either sold or reissued, the Company uses the last in, first out method. If the proceeds from the re-issuance of treasury stock are greater than the cost, the excess is recorded as additional paid-in capital. If the proceeds from re-issuance of treasury stock are less than the cost, the excess cost first reduces any additional paid-in capital arising from previous treasury stock transactions for that class of stock, and any additional excess is recorded as a reduction of retained earnings.

Accounting for stock-based compensation

The Company has one stock-based employee compensation plan, the Fourth Amended and Restated Emergent BioSolutions Inc. 2006 Stock Incentive Plan (the "Emergent Plan") under which the Company may grant various types of equity awards including stock options, restricted stock units and performance stock units. For all of our share-based awards, the Company recognizes forfeitures and compensation costs when they occur.

The terms and conditions of equity awards (such as price, vesting schedule, term and number of shares) under the Emergent Plan is determined by the compensation committee of the Company's board of directors, which administers the Emergent Plan. Each equity award granted under the Emergent Plan vests as specified in the relevant agreement with the award recipient and no option can be exercised after seven years from the date of grant. The Company records the estimated fair value of awards in expense on a straight-line basis over the requisite service period, which is generally the vesting period. Where awards are made with non-substantive vesting periods (for instance, where a portion of the award vests upon retirement eligibility), the Company estimates and recognizes expense based on the period from the grant date to the date the employee becomes retirement eligible.

The Company determines the fair value of restricted stock units using the closing market price of the Company's common stock on the day prior to the date of grant. The Company's performance stock units settle in the Company's stock. The fair value is determined on the date of the grant using the number of shares expected to be earned and the ending market value of the stock on the day prior to the grant date. The number of shares expected to vest is adjusted each reporting period by assessing the probability that the performance criteria will be met and the associated targeted payout level that is forecasted will be achieved.

The Company utilizes the Black-Scholes valuation model for estimating the fair value of all stock options granted. Set forth below is a discussion of the Company's methodology for developing each of the assumptions used:

▪Expected dividend yield — the Company does not pay regular dividends on its common stock and does not anticipate paying any dividends in the foreseeable future.

▪Expected volatility — a measure of the amount by which a financial variable, such as share price, has fluctuated (historical volatility) or is expected to fluctuate (implied volatility) during a period. The Company analyzed its own historical volatility to estimate expected volatility over the same period as the expected average life of the options.

▪Risk-free interest rate — the range of U.S. Treasury rates with a term that most closely resembles the expected life of the option as of the date on which the option is granted.

78

▪Expected average life of options — the period of time that options granted are expected to remain outstanding, based primarily on the Company's expectation of option exercise behavior subsequent to vesting of options.

Pension plans

The Company maintains defined benefit plans for employees in certain countries outside the U.S., including retirement benefit plans required by applicable local law. The plans are valued by independent actuaries using the projected unit credit method. The liabilities correspond to the projected benefit obligations of which the discounted net present value is calculated based on years of employment, expected salary increase, and pension adjustments. The Company reviews its actuarial assumptions on an annual basis and makes modifications to the assumptions based on current rates and trends. Actuarial gains and losses are deferred in accumulated other comprehensive income (loss), net of tax and are amortized over the remaining service attribution periods of the employees under the corridor method. Differences between the expected long-term return on plan assets and the actual annual return are amortized to net periodic benefit cost over the estimated remaining life as a component of selling, general and administrative expenses in the consolidated statements of operations.

Derivative instruments and hedging activities

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company has entered into interest rate swaps to manage exposures that arise from the Company's payments of variable interest rate debt under its senior secured credit agreements.

The Company's interest rate swaps qualify for hedge accounting as cash flow hedges. All derivatives are recorded on the balance sheet at fair value. Hedge accounting provides for the matching of the timing of gain or loss recognition on these interest rate swaps with the recognition of the changes in interest expense on the Company's variable rate debt. For derivatives designated as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in accumulated other comprehensive income (loss) and subsequently reclassified into interest expense in the same period during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate debt. The cash flows from the designated interest rate swaps are classified as a component of operating cash flows, similar to interest expense. 

The valuation of the interest rate swaps is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each interest rate swap. This analysis reflects the contractual terms of the interest rate swaps, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments (or receipts) and the discounted expected variable cash receipts (or payments). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. To comply with the provisions of ASC 820, Fair Value Measurement, the Company incorporates credit valuation adjustments in the fair value measurements to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk. These credit valuation adjustments were concluded to not be significant inputs for the fair value calculations for the periods presented. In adjusting the fair value of the Company's derivative contracts for the effect of nonperformance risk, it has considered the impact of netting and any applicable credit enhancements, such as the posting of collateral, thresholds, mutual puts and guarantees. The valuation of interest rate swaps fall into Level 2 in the fair value hierarchy. See Note 8, "Derivative instruments" for further details on the interest rate swaps.

(2) Amounts for the Company's Services segment include gross carrying values of $6.7 million as of December 31, 2022, 2021, and 2020, and accumulated impairment losses of $6.7 million representing the aggregate impairment charges for the year ended December 31, 2022.

82

As a result of the Company's annual goodwill impairment test on October 1, 2022 the Company recorded a $6.7 million non-cash goodwill impairment charge included in "Goodwill impairment" in the Statements of Operations during the year ended December 31, 2022 in the CDMO - Services reporting unit within the Services segment. The CDMO - Services reporting unit and Services segment had no remaining goodwill balance as of December 31, 2022. The goodwill impairment charge resulted from a reduction in the estimated fair value of the CDMO-Services reporting unit due to changes to the long-term operating plan that reflected lower expectations for growth and profitability than previous expectations. The Company used a quantitative assessment, utilizing a income based (discounted cash flows) approach, Level 3 non-recurring fair value measurement, for our goodwill impairment testing for all of our reporting units in 2022. Outside of our CDMO - Services reporting unit, the assessments completed for all other reporting units during the year ended December 31, 2022 indicated no impairment.

On October 1, 2021, the Company reorganized its lines of business resulting in a change in the composition of two of its reporting units and performed its annual impairment testing using quantitative tests to determine fair values of the reporting units both before and after the reorganization of the lines of business and its reporting units. Using both a market based (comparable company multiple) and income based (discounted cash flows) approach, each a Level 3 non-recurring fair value measurement, the Company determined that there was a goodwill impairment of $41.7 million included in "Goodwill impairment" in the Statements of Operations in the Commercial products reporting unit within our Products segment. The Company used a qualitative assessment for our goodwill impairment testing for all other reporting units in 2021. The assessments completed for all other reporting units during the year ended December 31, 2021 indicated no impairment.

7. Fair value measurements

The table below presents information about the Company's assets and liabilities that are regularly measured and carried at fair value and indicate the level within the fair value hierarchy of the valuation techniques we utilized to determine fair value:

	December 31, 2022								December 31, 2021
	(As Restated)								(As Revised)
	Total		Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3

Total	$	8.0	$	—	$	—	$	8.0	$	44.5	$	—	$	6.1	$	38.4

Contingent consideration

Contingent consideration liabilities associated with business combinations are measured at fair value. These liabilities represent an obligation of the Company to transfer additional assets to the selling shareholders and owners if future events occur or conditions are met. These liabilities associated with business combinations are measured at fair value at inception and at each subsequent reporting date. The changes in the fair value are primarily due to the expected amount and timing of future net sales, which are inputs that have no observable market. Any changes in fair value for the contingent consideration liabilities related to the Company’s products are classified in the Company's statement of operations as cost of product sales. Any changes in fair value for the contingent consideration liabilities related to the Company’s product candidates are recorded in R&D expense for regulatory and development milestones.

83

The following table is a reconciliation of the beginning and ending balance of the contingent consideration liabilities measured at fair value during the years ended December 31, 2022, 2021 and 2020.

	Contingent Consideration
Balance at December 31, 2019 (As Revised)	$	30.4
Expense included in earnings	31.7
Settlements	(2.8)
Balance at December 31, 2020 (As Revised)	$	59.3
Expense included in earnings	2.9
Settlements	(23.8)
Balance at December 31, 2021 (As Revised)	$	38.4
Expense included in earnings	2.6
Settlements	(33.0)
Balance at December 31, 2022 (As Restated)	$	8.0

As of December 31, 2022 and 2021, the current portion of the contingent consideration liability was $3.4 million and $32.7 million, respectively, and was included in "other current liabilities" on the consolidated balance sheets. The non-current portion of the contingent consideration liability is included in "other liabilities" on the consolidated balance sheets.

The recurring Level 3 fair value measurements for the Company's contingent consideration liability include the following significant unobservable inputs:

Contingent Consideration Liability	Fair Value as of December 31, 2022 (As Restated)	Valuation Technique	Unobservable Input	Range
Royalty based	$8.0 million	Discounted cash flow	Discount rate	9.9%
			Probability of payment	25.0% - 50.0%
			Projected year of payment	2023 - 2028

Non-Variable Rate Debt

As of December 31, 2022 and 2021, the fair value of the Company's 3.875% Senior Unsecured Notes was $225.1 million and $433.3 million, respectively. The fair value was determined through market sources, which are Level 2 inputs and directly observable. The carrying amounts of the Company’s other long-term variable interest rate debt arrangements approximate their fair values (see Note 9, "Debt").

Non-recurring fair value measurements

Separate disclosure is required for assets and liabilities measured at fair value on a recurring basis from those measured at fair value on a non-recurring basis. As of December 31, 2022 and December 31, 2021, other than those outlined in Note 6 "Intangible assets and goodwill", there were no material assets or liabilities measured at fair value on a non-recurring basis.

8. Derivative instruments and hedging activities

Risk management objective of using derivatives

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity and credit risk primarily by managing the amount, sources and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company has entered into interest rate swaps to manage exposures that arise from payments of variable interest rate debt associated with the Company's senior secured credit agreements.

84

If current fair values of designated interest rate swaps remained static over the next twelve months, the Company would reclassify $8.5 million of net deferred gains from accumulated other comprehensive income (loss) to the statement of operations over the next twelve month period. All outstanding cash flow hedges mature in October 2023.

As of December 31, 2022, the Company had the following outstanding interest rate swap derivatives that were designated as cash flow hedges of interest rate risk:

	Number of Instruments	Notional amount
Interest Rate Swaps	7	$350.0

The table below presents the fair value of the Company’s derivative financial instruments designated as hedges as well as their classification on the balance sheet.

	Fair Value of Asset Derivatives					Fair Value of Liability Derivatives
		December 31,					December 31
	Balance Sheet Location	2022		2021		Balance Sheet Location	2022		2021
Interest Rate Swaps	Other Current Assets	$	8.5	$	—	Other Current Liabilities	$	—	$	4.5
	Other Assets	$	—	$	—	Other Liabilities	$	—	$	1.6

The valuation of the interest rate swaps is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each interest rate swap. This analysis reflects the contractual terms of the interest rate swaps, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair values of interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash payments (or receipts) and the discounted expected variable cash receipts (or payments). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. We incorporate credit valuation adjustments in the fair value measurements to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk. These credit valuation adjustments were not significant inputs for the fair value calculations for the periods presented. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as the posting of collateral, thresholds, mutual puts and guarantees. The valuation of interest rate swaps fall into Level 2 in the fair value hierarchy.

The table below presents the effect of cash flow hedge accounting on accumulated other comprehensive income (loss):

	Cumulative Amount of Gain/(Loss) Recognized in OCI on Derivatives				Location of Loss Reclassified from Accumulated OCI(L) into Income (Loss)	Amount of Loss Reclassified from Accumulated OCI(L) into Income (Loss)
	December 31,					Year Ended December 31,
	2022		2021			2022		2021
Interest Rate Swaps	$	8.5	$	(6.1)	Interest expense	$	(0.1)	$	(5.8)

9. Debt

The components of debt are as follows:

	December 31,
	2022		2021
Senior secured credit agreement - Term loan due 2023	$	362.8	$	396.6
Senior secured credit agreement - Revolver loan due 2023	598.0		—
3.875% Senior Unsecured Notes due 2028	450.0		450.0
Other	3.0		3.0
Total debt	$	1,413.8	$	849.6
Current portion of long-term debt, net of debt issuance costs	(957.3)		(31.6)
Unamortized debt issuance costs	(8.0)		(8.5)
Non-current portion of debt	$	448.5	$	809.4

As of December 31, 2022 there was a $598.0 million outstanding revolver loan balance. There was no outstanding revolver loan balance as of December 31, 2021. During the year ended December 31, 2022, the Company reclassified the debt issuance costs associated with the revolver loan to a contra account to directly offset the loan balance in other current liabilities on the Company's consolidated balance sheets. As of December 31, 2022, the Company had approximately $1.3 million debt issuance costs associated with the revolver loan that were classified as an offset to other current liabilities. Prior to 2022, the debt issuance costs associated with the revolver load were included in other current assets and other assets on the Company's consolidated balance sheets. As of December 31, 2021, the Company had approximately $2.0 million and $1.6 million of debt issuance costs associated with the revolver loan that were classified as other current assets and other assets, respectively.

3.875% Senior Unsecured Notes due 2028

On August 7, 2020, the Company completed its offering of $450.0 million aggregate principal amount of 3.875% Senior Unsecured Notes due 2028 (the "Senior Unsecured Notes") of which the majority of the net proceeds were used to pay down the Revolving Credit Facility (as defined below). Interest on the Senior Unsecured Notes is payable on February 15th and August 15th of each year until maturity, beginning on February 15, 2021. The Senior Unsecured Notes will mature on August 15, 2028.

On or after August 15, 2023, the Company may redeem the Senior Unsecured Notes, in whole or in part, at the redemption prices set forth in the related Indenture, plus accrued and unpaid interest. Prior to August 15, 2023 the Company may redeem all or a portion of the Senior Unsecured Notes at a redemption price equal to 100% of the principal amount of the Senior Unsecured Notes plus a “make-whole” premium and accrued and unpaid interest. Prior to August 15, 2023, the Company may redeem up to 40% of the aggregate principal amount of the Senior Unsecured Notes using the net cash proceeds of certain equity offerings at the redemption price set forth in the related Indenture. Upon the occurrence of a change of control, the Company must offer to repurchase the Senior Unsecured Notes at a purchase price of 101% of the principal amount of such Senior Unsecured Notes plus accrued and unpaid interest.

Negative covenants in the Indenture governing the Senior Unsecured Notes, among other things, limit the ability of the Company to incur indebtedness and liens, dispose of assets, make investments, enter into certain merger or consolidation transactions and make restricted payments.

Senior Secured Credit Agreement

Also on August 7, 2020, the Company entered into a Second Amendment (the "Second Credit Agreement Amendment") to its senior secured credit agreement, dated October 15, 2018, with multiple lending institutions relating to the Company’s senior secured credit facilities (the Credit Agreement, and as amended, the Amended Credit Agreement), consisting of Revolving Credit Facility and Term Loan Facility, and together with the Revolving Credit Facility, the Senior Secured Credit Facilities. The Second Credit Agreement Amendment amended, among other things, the definition of incremental facilities limit, the consolidated net leverage ratio financial covenant by increasing the maximum level, increased the permissible applicable margins based on the Company’s consolidated net leverage ratio and increased the commitment fee that the Company is required to pay in respect of the average daily unused commitments under the Revolving Credit Facility, depending on the Company’s consolidated net leverage ratio.

86

The Amended Credit Agreement includes (i) a Revolving Credit Facility of $600.0 million with a maturity date of October 13, 2023, and (ii) a Term Loan Facility with a principal amount of $450.0 million. The Company may request incremental term loan facilities or increases in the Revolving Credit Facility (each an Incremental Loan) as long as certain requirements involving our net leverage ratio will be maintained on a pro forma basis. Borrowings under the Revolving Credit Facility and the Term Loan Facility bear interest at a rate per annum equal to (a) a eurocurrency rate plus a margin ranging from 1.3% to 2.3% per annum, depending on the Company's consolidated net leverage ratio or (b) a base rate (which is the highest of the prime rate, the federal funds rate plus 0.5%, and a eurocurrency rate for an interest period of one month plus 1.0% plus a margin ranging from 0.3% to 1.3%, depending on the Company's consolidated net leverage ratio. The Company is required to make quarterly payments on the last business day of each calendar quarter under the Amended Credit Agreement for accrued and unpaid interest on the outstanding principal balance, based on the above interest rates. In addition, the Company is required to pay commitment fees ranging from 0.2% to 0.4% per annum, depending on the Company's consolidated net leverage ratio, for the average daily unused commitments under the Revolving Credit Facility. The Company is to repay the outstanding principal amount of the Term Loan Facility in quarterly installments on the last business day of each calendar quarter based on an annual percentage equal to 2.5% of the original principal amount of the Term Loan Facility during each of the first two years of the Term Loan Facility, 5.0% of the original principal amount of the Term Loan Facility during the third year of the Term Loan Facility and 7.5% of the original principal amount of the Term Loan Facility during each year of the remainder of the term of the Term Loan Facility until the maturity date of the Term Loan Facility, at which time the entire unpaid principal balance of the Term Loan Facility will be due and payable. The Company has the right to prepay the Term Loan Facility without premium or penalty. The Revolving Credit Facility and the Term Loan Facility mature on October 13, 2023.

The Amended Credit Agreement also requires mandatory prepayments of the Term Loan Facility in the event the Company or its subsidiaries (a) incur indebtedness not otherwise permitted under the Amended Credit Agreement or (b) receive cash proceeds in excess of $100.0 million during the term of the Credit Agreement from certain dispositions of property or from casualty events involving their property, subject to certain reinvestment rights. The financial covenants under the Amended Credit Agreement currently require the quarterly presentation of a minimum consolidated 12-month rolling debt service coverage ratio of 2.5 to 1.0, and a maximum consolidated net leverage ratio of 4.5 to 1.0 (subject to an increase to 5.0 to 1.0 for an applicable four quarter period, at the election of the Company, in connection with a permitted acquisition having an aggregate consideration in excess of $75.0 million). Negative covenants in the Amended Credit Agreement, among other things, limit the ability of the Company to incur indebtedness and liens, dispose of assets, make investments, enter into certain merger or consolidation transactions and make restricted payments.

On February 14, 2023, the Company entered into a Consent, Limited Waiver, and Third Amendment to the Amended and Restated Credit Agreement relating to the Senior Secured Credit Facilities. Pursuant to the Third Credit Agreement Amendment, the requisite lenders consented to our sale of our travel health business to Bavarian Nordic substantially in accordance with the terms of the Sale Agreement. The proceeds from the transaction will be deposited into a cash collateral account with the Administrative Agent and will, unless otherwise agreed to by the Company and the requisite lenders, be used to repay the outstanding Term Loan Facility on the expiration of the Limited Waiver (as described below). We currently expect the transaction to close in the second quarter of 2023, but we can provide no assurance that the transaction will close prior to the October 2023 maturity of the Term Loan Facility, or at all.

Pursuant to the Third Credit Agreement Amendment the requisite lenders have agreed to a limited waiver of any defaults or events of default that result from (a) any violation of the financial covenants set forth in the Senior Secured Credit Facilities with respect to the fiscal quarters ending December 31, 2022 and March 31, 2023 and (b) the going concern qualification or exception contained in the audited financial statements for the fiscal year ending December 31, 2022. This limited waiver will expire on the earlier to occur of (i) any other event of default and (ii) April 17, 2023. During this period the Company is working with lenders under the Senior Secured Credit Facilities in connection with replacing such facilities before their October 2023 maturity with revised terms and conditions. The Company does not expect to be in compliance with debt covenants in future periods without additional sources of liquidity or future amendments to the Credit Agreement. See Footnote 3 "Summary of significant accounting policies" for Going Concern considerations related to noncompliance with our debt covenants and the limited waiver.

Preferred stock

The Company is authorized to issue up to 15.0 million shares of preferred stock, $0.001 par value per share ("Preferred Stock"). Any Preferred Stock issued may have dividend rights, voting rights, conversion privileges, redemption characteristics, and sinking fund requirements as approved by the Company's board of directors.

Common stock

The Company currently has one class of common stock, $0.001 par value per share common stock ("Common Stock"), authorized and outstanding. The Company is authorized to issue up to 200.0 million shares of Common Stock. Holders of Common Stock are entitled to one vote for each share of Common Stock held on all matters, except as may be provided by law.

2021 Stock Repurchase program

On November 11, 2021, the Company announced that its board of directors authorized a stock repurchase program of up to an aggregate of $250.0 million of Common Stock (the "Share Repurchase Program"). The Share Repurchase Program expired on November 11, 2022. The Company utilized $187.9 million to purchase 4.4 million shares as of the program expiration date. The Share Repurchase Program did not obligate the Company to acquire any specific number of shares. Repurchased shares are available for use in connection with our stock plans and for other corporate purposes.

The following table details our stock repurchases under the Share Repurchase Program:

	Year Ended December 31,
	2022		2021
Shares of common stock repurchased	1.8		2.6

Total cost	$	75.5	$	112.6

Accounting for share-based compensation

The Company has one share-based employee compensation plan, the Emergent Plan, which includes stock options and performance and restricted stock units.

As of December 31, 2022, an aggregate of 25.4 million shares of common stock were authorized for issuance under the Emergent Plan, of which a total of approximately 2.9 million shares of common stock remain available for future awards to be made to plan participants. The exercise price of each option must be not less than 100% of the fair market value of the shares underlying such option on the date of grant. Options granted under the Emergent Plan have a contractual life of seven years.

88

The Company utilizes the Black-Scholes valuation model for estimating the fair value of all stock options granted. Set forth below are the assumptions used in valuing the stock options granted:

	Year Ended December 31,
	2022		2021		2020
Expected dividend yield	0	%	0	%	0	%
Expected volatility	54%-62%		47-48%		39-48%
Risk-free interest rate	1.54%-4.31%		0.43-0.94%		0.27-1.42%
Expected average life of options	4.5 years		4.5 years		4.5 years

Stock options, restricted stock units and performance stock units

The following is a summary of stock option award activity under the Emergent Plan:

	Number of Shares	Weighted-Average Exercise Price		Weighted Average Remaining Contractual Term (in Years)	Aggregate Intrinsic Value
Stock options outstanding at December 31, 2021	1.2	$	60.83		$	3.0
Stock options granted	0.7	$	39.11
Stock options exercised	—	$	27.71
Stock options forfeited	(0.2)	$	64.66
Stock options outstanding at December 31, 2022	1.7	$	51.74	4.1	$	—
Stock options exercisable at December 31, 2022	0.8	$	54.14	2.3	$	—

Cash received from option exercises for the years ended December 31, 2022, 2021 and 2020 was $0.5 million, $10.4 million and $27.6 million, respectively.

The weighted average grant date fair value of options granted during the years ended December 31, 2022, 2021, and 2020 was $17.85, $35.16 and $21.69 per share, respectively. The total intrinsic value of options exercised during the years ended December 31, 2022, 2021, and 2020 was $0.3 million, $15.7 million and $38.2 million, respectively. As of December 31, 2022, there was $12.0 million of unrecognized compensation cost related to stock options.

The following is a summary of performance stock unit and restricted stock unit award activity under the Emergent Plan:

	Number of Shares	Weighted-Average Grant Date Fair Value		Aggregate  Intrinsic Value
Stock awards outstanding at December 31, 2021	1.1	$	70.82	$	47.6
Stock awards granted (1)	1.9	$	34.49
Stock awards released	(0.5)	$	67.48
Stock awards forfeited (1)	(0.3)	$	55.46
Stock awards outstanding at December 31, 2022	2.2	$	42.30	$	25.8
(1) Performance stock units granted and forfeited during the year ended December 31, 2022 are included at the target payout percentage, or 100%, of shares granted.

The total fair value of restricted stock unit awards released during the years ended December 31, 2022, 2021 and 2020 was $30.9 million, $26.9 million and $34.1 million, respectively. As of December 31, 2022, there was $54.5 million of unrecognized compensation cost related to unvested restricted stock units. That cost is expected to be recognized ratable over a weighted average period of 1.9 years.

89

Performance stock units represent common stock potentially issuable in the future, subject to achievement of performance conditions. Our current outstanding performance stock units vest based on certain financial metrics over the applicable performance period. The vesting and payout range for our performance stock units is typically between 50% and up to 150% of the target number of shares granted at the end of a three-year performance period. The total fair value of performance unit awards released during the years ended December 31, 2022, 2021 and 2020 was $2.5 million, $3.8 million and $1.2 million, respectively. As of December 31, 2022, there was $5.3 million of unrecognized compensation cost related to unvested performance stock units. That cost is expected to be recognized ratable over a weighted average period of 1.9 years.

11. Net income (loss) per common share

The following table presents the calculation of basic and diluted net income (loss) per common share:

	Year Ended December 31,
	2022		2021		2020
	(As Restated)		(As Revised)		(As Revised)
Numerator:
Net income (loss)	$	(211.6)	$	219.5	$	305.8
Denominator:
Weighted-average number of shares-basic	50.1		53.5		52.7
Dilutive effect of employee incentive plans	—		0.6		1.1
Weighted-average number of shares-diluted	50.1		54.1		53.8
Net income (loss) per common share - basic	$	(4.22)	$	4.10	$	5.80
Net income (loss) per common share - diluted	$	(4.22)	$	4.06	$	5.68

Basic net income (loss) per common share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per common share is computed using the treasury method by dividing net income by the weighted average number of shares of common stock outstanding during the period, adjusted for the potential dilutive effect of other securities if such securities were converted or exercised and are not anti-dilutive. No adjustment for the potential dilutive effect of dilutive securities is reported for the year ended December 31, 2022 as the effect would have been anti-dilutive due to the Company's net loss.

The following table presents the share-based awards that are not considered in the diluted net income (loss) per common share calculation generally because the exercise price of the awards was greater than the average per share closing price during the year ending December 31, 2022, 2021 and 2020. In certain instances, awards may be anti-dilutive even if the average market price exceeds the exercise price when the sum of the assumed proceeds exceeds the difference between the market price and the exercise price.

	Year Ended December 31,
	2022	2021	2020
Anti-dilutive stock awards	2.8	1.0	—

For the years ended December 31, 2022, 2021 and 2020, the Company's product sales from Anthrax Vaccines, Nasal Naloxone products, TEMBEXA, ACAM2000 and Other products as a percentage of total product sales were as follows:

	Year Ended December 31,
	2022		2021		2020

ACAM2000	7	%	20	%	20	%
Other products	14	%	12	%	11	%

For the year ended December 31, 2022 there were two customers in excess of 10% of total revenues. The USG accounted for 43% of total revenues and the second customer accounted for 10% of total revenues. Both customer's revenue is attributable to the Products segment. For the years ended 2021 and 2020, aside from sales to the USG, there were no sales to an individual customer in excess of 10% of total revenues. For the years ended December 31, 2022, 2021, and 2020, the Company’s revenues from customers within the United States comprised 79%, 92% and 93%, respectively, of total revenues.

Termination of manufacturing services agreement with Janssen Pharmaceuticals, Inc.

On July 2, 2020, the Company, through its wholly-owned subsidiary, Emergent Manufacturing Operations Baltimore, LLC, entered into the Agreement with Janssen, one of the Janssen Pharmaceutical Companies of Johnson & Johnson, for large-scale drug substance manufacturing of Johnson & Johnson’s investigational SARS-CoV-2 vaccine, Ad26.COV2-S, recombinant based on the AdVac technology (the “Product”).

On June 6, 2022, the Company provided to Janssen a notice (the “Notice”) of material breach of the Agreement for, among other things, failure by Janssen (i) to provide the Company the requisite forecasts of the required quantity of Product to be purchased by Janssen under the Agreement and (ii) to confirm Janssen’s intent to not purchase the requisite minimum quantity of the Product pursuant to the Agreement and instead, wind-down the Agreement ahead of fulfilling these minimum requirements. Later on June 6, 2022, the Company received from Janssen a purported written notice of termination (the “Janssen Notice”) of the Agreement for asserted material breaches of the Agreement by the Company, including alleged failure by the Company to perform its obligations in compliance with current good manufacturing practices ("cGMP") or other applicable laws and regulations and alleged failure by the Company to supply Janssen with the Product. Janssen alleged that the Company’s breaches were not curable and that, therefore, termination of the Agreement would be effective as of July 6, 2022. The Company disputes Janssen's assertions and allegations, including Janssen's ability to effect termination pursuant to the Janssen Notice. The Company and Janssen disagree on the monetary amounts that are

92

due to the Company as a result of termination by any means. The Company believes the amounts due to the Company include, but are not limited to, compensation for services provided, reimbursement for raw materials purchased and non-cancelable orders, and fees for early termination. Janssen has alleged that no additional amount is due to the Company and that the Company should pay Janssen an unspecified amount as a result of the Company's alleged failure to perform under the Agreement. The Company has not recorded any contingent liabilities related to Janssen's allegations as the Company believes they are without merit and intends to vigorously defend the Company's position during the dispute resolution process through arbitration.

During the year ended December 31, 2022, there were no impacts on previously recognized revenue or depreciation related to the conclusion of the Agreement. As of December 31, 2022, the Company has no billed or unbilled net accounts receivable related to the Agreement.

Because the arbitration process may extend longer than one year, the Company reclassified $127.7 million from "Inventories, net" and $25.0 million from "Prepaid expenses and other current assets" to "Other assets" in the fourth quarter resulting in $152.7 million in long-term assets related to the Janssen Agreement on the consolidated balance sheet as of December 31, 2022. These assets include termination penalties, certain inventory related items and raw materials inventory representing materials purchased for the Agreement which Janssen has not reimbursed. The Company evaluated the net realizable value of the inventory as of December 31, 2022, concluding that because the Agreement specifies the Company is entitled to, among other things, reimbursement of raw materials and non-cancelable orders in the event of a contract termination for any reason, the Company is entitled to payment from Janssen for these raw materials. Additionally, the Company has $6.2 million of non-cancelable orders as of December 31, 2022 which have not been received and Janssen has not reimbursed.

BARDA Centers of Innovation and Advanced Development and Manufacturing Agreement

In 2020, the Company announced the issuance of a task order under its existing CIADM agreement with BARDA for COVID-19 vaccine development and manufacturing (the "BARDA COVID-19 Development Public Private Partnership"). The BARDA COVID-19 Development Public Private Partnership is considered a lease and is accounted for under ASC 842. The initial task order had a contract value of up to $628.2 million and included the reservation of manufacturing capacity and accelerated expansion of fill/finish capacity valued at $542.7 million and $85.5 million, respectively. Subsequently, the task order was expanded to include incremental capital activities which increased the value to $650.8 million. On November 1, 2021, the Company and BARDA mutually agreed to the completion of the Company's CIADM contract and associated task orders, including the BARDA COVID-19 Development Public Private Partnership. The Company did not recognize lease revenues under this arrangement during the year ended December 31, 2022. Total revenues associated with the base arrangement were $71.3 million and $15.8 million during the years ended December 31, 2021 and December 31, 2020, respectively, and are reflected as a component of contracts and grants revenue on the consolidated statements of operations. Revenues associated with the BARDA COVID-19 Development Public-Private Partnership were $243.1 million and $247.8 million during the years ended December 31, 2021 and December 31, 2020, respectively, and are recorded as CDMO leases on the consolidated statements of operations.

CDMO Operating Leases

Certain multi-year CDMO service arrangements with non-USG customers include operating leases whereby the customer has the right to direct the use of and obtain substantially all of the economic benefits of specific manufacturing suites operated by the Company. The associated revenue is recognized on a straight-line basis over the term of the lease. The remaining term on the Company's operating lease components approximates 2.6 years. The Company utilizes a cost-plus model to determine the stand-alone selling price of the lease component to allocate contract consideration between the lease and non-lease components. During the year ended December 31, 2022, the Company's non-USG lease revenues were $4.9 million, which is included within CDMO leases in the consolidated statement of operations. Excluding future amounts related to the Agreement as discussed above, the Company estimates future operating lease revenues to be $5.1 million in 2023, $0.9 million in 2024, $0.9 million in 2025, and $2.7 million in years beyond 2025.

93

Transaction price allocated to remaining performance obligations

As of December 31, 2022, the Company expects future revenues of approximately $378.2 million associated with all arrangements entered into by the Company. The Company expects to recognize a majority of the $378.2 million of unsatisfied performance obligations within the next 24 months. The amount and timing of revenue recognition for unsatisfied performance obligations can change. The future revenues associated with unsatisfied performance obligations exclude the value of unexercised option periods in the Company’s revenue arrangements. Often the timing of manufacturing activities changes based on customer needs and resource availability. Government funding appropriations can impact the timing of product deliveries. The success of the Company's development activities that receive development funding support from the USG under development contracts can also impact the timing of revenue recognition.

Contract assets

The Company considers accounts receivable and deferred costs associated with revenue generating contracts, which are not included in inventory or property, plant and equipment and the Company does not currently have a contractual right to bill, to be contract assets. As of December 31, 2022 and December 31, 2021, the Company had $34.8 million and $21.5 million, respectively, of contract assets recorded within accounts receivable, net on the consolidated balance sheets.

Contract liabilities

When performance obligations are not transferred to a customer at the end of a reporting period, cash received associated with the amount allocated to those performance obligations is reflected as contract liabilities on the consolidated balance sheets and is deferred until control of these performance obligations is transferred to the customer.

The following table presents the roll forward of the contract liabilities:

	Contract Liabilities
Balance at December 31, 2020 (As Revised)	$	100.1
Deferral of revenue	279.7
Revenue recognized	(363.4)
Balance at December 31, 2021 (As Revised)	$	16.4
Deferral of revenue	38.9
Revenue recognized	(23.6)
Balance at December 31, 2022 (As Restated)	$	31.7

As of December 31, 2022 and 2021, the current portion of contract liabilities was $26.4 million and $11.7 million, respectively, and was included in other current liabilities on the balance sheet.

Accounts Receivable and Allowance for Expected Credit Losses

Accounts receivable including unbilled accounts receivable contract assets consist of the following:

13. Leases

The Company is the lessee for operating corporate leases for offices, R&D facilities and manufacturing facilities. The Company determines if an arrangement is a lease at inception. Operating leases are included in right-of-use ("ROU") assets and liabilities. For a discussion of lessor activities, see Note 12, "Revenue recognition".

The components of lease expense were as follows:

	Year Ended December 31,
	2022		2021		2020
Operating lease cost:
Amortization of right-of-use assets	$	5.6	$	5.6	$	4.5

During the year ended December 31, 2022, the Company exercised the option to purchase its Rockville manufacturing facility. As a result, the Company removed the related operating lease right-of-use asset and operating lease liability of $3.5 million and $3.4 million, respectively. The purchased assets have been properly included in "Property, plant and equipment, net" on the Company's consolidated balance sheet as of December 31, 2022.

The Company's leases have remaining lease terms of less than one year to approximately 11 years, some of which include options to extend the leases for up to five years, and some of which include options to terminate the leases within one year.

14. Income taxes

The Company uses the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse. Valuation allowances are recorded as appropriate to reduce deferred tax assets to the amount considered likely to be realized.

The Company establishes valuation allowances for deferred income tax assets in accordance with U.S. GAAP, which provides that such valuation allowances shall be established unless realization of the income tax benefits is more likely than not. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible.

As of December 31, 2022, the Company reassessed the valuation allowance and considered negative evidence, including its significant losses in the current year and the substantial doubt about the Company’s ability to continue as a going concern through one year from the date that these financial statements are issued, positive evidence, scheduled reversal of deferred tax liabilities, available taxes in carryback periods, tax planning strategies and projected future taxable income. After assessing both the negative and positive evidence, the Company concluded that it should record an additional valuation allowance of $37.8 million on its global net operating losses, credits and other deferred tax assets.

The global intangible low-tax income (“GILTI”) provisions require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. The Company is subject to incremental U.S. tax on GILTI income. The Company has elected to account for GILTI tax in the period in which it is incurred, and therefore has not provided any deferred tax impacts of GILTI in its consolidated financial statements for the year ended December 31, 2022 and 2021. BEAT provisions do not have material impact on the consolidated financial statements.

For the year ended December 31, 2022, the Company has evaluated its historical indefinite reinvestment assertion in connection with the Company’s going concern uncertainty. The Company recognized a deferred withholding tax liability for the undistributed earnings of the Company’s international subsidiaries available cash and net working capital in the amount of $4.7 million. All other international subsidiaries’ outside basis differences are indefinitely reinvested.

Significant components of income taxes attributable to operations consist of the following:

As of December 31, 2022, the Company has approximately $70.5 million in U.S. federal net operating loss ("NOL") carryforwards, $36.0 million of NOL’s which will expire in varying amounts in 2031 through 2035 and $34.5 million which will carryforward indefinitely, although, limited to eighty percent of taxable income annually. The Company has U.S. federal tax credit carryforwards of $13.4 million which will expire in 2027 through 2042.

As of December 31, 2022, the Company had pre-apportionment state NOLs totaling approximately $1.7 billion primarily in Maryland which will begin to expire in 2025 and post-apportionment NOLs totaling approximately $146.5 million that will begin to expire in 2028. The Company has state R&D tax credit carryforwards of $5.0 million which will expire in 2027 through 2038.

The deductibility of such US federal and state net operating losses and credits may be limited. Under Section 382/383 of the Internal Revenue Code of 1986, as amended (the “Code”), and corresponding provisions of state law, if a corporation undergoes an "ownership change," which generally occurs if the percentage of the corporation's stock owned by 5% stockholders increases by more than 50% over a three-year period, the corporation's ability to use its pre-change NOL carryforwards and other pre-change tax attributes to offset its post-change income may be limited. Certain of the net operating loss carryforwards and the credit carryforwards are subject to an annual limitation pursuant to Internal Revenue Code Section 382 and 383 as a result of historical acquisitions. We may experience ownership changes in the future as a result of subsequent shifts in our stock ownership, some of which may be outside of our control, which may further limit our carryforwards. If we determine that an ownership change has occurred and our ability to use our historical NOL and

97

credit carryforwards is materially limited, it would harm our future operating results by effectively increasing our future tax obligations.

The Company has approximately $51.5 million in net operating losses from foreign jurisdictions as of December 31, 2022, $14.5 million of losses which will expire in varying amounts in 2022 through 2028 and $37.0 million will carryforward indefinitely.

The Company’s valuation allowance increased by $37.8 million due to the Company’s determination that it is not more likely than not to realize its global net deferred income tax assets and the current year losses incurred within the U.S. The valuation allowance has been recorded primarily against the Company's net operating loss and credit carryforwards.

Income taxes differ from the amount of taxes determined by applying the U.S. federal statutory rate to income before taxes as a result of the following:

	Year Ended December 31,
	2022		2021		2020
	(As Restated)		(As Revised)		(As Revised)
U.S.	$	(442.6)	$	100.1	$	368.2

Earnings (Losses) before taxes on income	(218.6)		303.4		411.9
Federal tax at statutory rates	$	(46.0)	$	63.5	$	86.5
State taxes, net of federal benefit	(13.5)		14.1		23.7

Foreign withholding tax	4.7		—		—
Permanent differences	3.2		(1.2)		2.1
Income tax (benefit) provision	$	(7.4)	$	83.7	$	106.1

The effective annual tax rate for the years ended December 31, 2022, 2021, and 2020 was 3%, 28% and 26%, respectively.

The effective annual tax rate of 3% in 2022 is lower than the statutory rate primarily due to the impact of a valuation allowance charge in the US, state and Foreign Jurisdictions, a charge due the Company’s indefinite reinvestment assertion, goodwill impairment, GILTI, and other permanent items. This is partially offset by tax credits, favorable rates in foreign jurisdictions, and the release of an indemnified unrecognized tax benefit.

The effective annual tax rate of 28% in 2021 is higher than the statutory rate primarily due to the impact of goodwill impairment, state taxes, GILTI and other non-deductible items. This is partially offset by stock option deduction benefits, tax credits, and favorable rates in foreign jurisdictions. The jurisdictional mix of profit has changed from the prior year largely due to lower U.S. CDMO margins, the termination of the CIADM arrangement in the U.S. and an increase in sales of NARCAN in which a portion of the profit is attributable to a foreign subsidiary.

The effective annual tax rate of 26% in 2020 is higher than the statutory rate primarily due to the impact of state taxes, GILTI, contingent consideration, other non-deductible items and the jurisdictional mix of earnings. This is partially offset by stock option deduction benefits, tax credits, and favorable rates in foreign jurisdictions.

The total unrecognized tax benefits recorded at December 31, 2022 and 2021 of $6.8 million and $12.7 million, respectively, is classified primarily as a non-current liability on the consolidated balance sheets.

98

The table below presents the gross unrecognized tax benefits activity for the years ended December 31, 2022, 2021 and 2020:

	Year Ended December 31,
	2022		2021		2020
	(As Restated)		(As Revised)		(As Revised)
Gross unrecognized tax benefits, beginning of period	$	12.7	$	12.2	$	8.9
Increases (decreases) for tax positions for prior years	(1.5)		0.3		—
Increases for tax positions for current year	0.7		0.2		5.1
Settlements	—		—		(1.8)
Lapse of statute of limitations	(5.1)		—		—
Gross unrecognized tax benefits, end of period	$	6.8	$	12.7	$	12.2

The total gross unrecognized tax benefit of $6.8 million, includes the release of $8.0 million of liability that related to the 2018 acquisition of PaxVax Holdings Company, Ltd. The liability was offset by an indemnification receivable, both of which were released due to a lapse of the statute of limitation during the year.

The Company includes interest and potential penalties related to unrecognized tax benefits in income tax expense. As of December 31, 2022 and 2021, the total amount of interest and penalties accrued was $1.6 million and $3.7 million, respectively. The Company recognized interest and penalty expense (benefit) in 2022, 2021 and 2020 of $(2.1) million, $1.1 million and $0.4 million, respectively.

The Company does not anticipate a significant change within the next twelve months for unrecognized tax benefits and when resolved, all of these liabilities would impact the effective tax rate. However, the Company maintains a full valuation allowance as of December 31, 2022 and the recognition of any unrecognized tax benefits would be offset with a change in the valuation allowance and therefore there would be no income statement impact.

The Company's federal and state income tax returns for the tax years 2019 and onwards remain open to examination. The Company's tax returns for Canada remain open to examination for the tax years 2014 through 2021. The Company's Irish tax returns remain open to examination for the tax years 2016 through 2021.

As of December 31, 2022, the Company’s 2018 Canadian Scientific Research and Experimental Development Claim is under appeal and the Company’s 2020 Canadian Scientific Research and Experimental Development Claim is under audit. The Company's 2016 and 2017 Canadian income tax returns for the Adapt entities are under audit. The Company’s Irish group is under Level 1 Compliance Intervention review for 2021. In addition, the Company’s 2019 and 2020 New York state income tax returns are under audit.

15. Defined benefit and 401(k) savings plan

The Company sponsors a defined benefit pension plan covering eligible employees in Switzerland (the "Swiss Plan"), which we have agreed to sell as part of our Travel Health business to Bavarian Nordic, described further in Note 19, "Subsequent events". Under the Swiss Plan, the Company and certain of its employees with annual earnings in excess of government determined amounts are required to make contributions into a fund managed by an independent investment fiduciary. Employer contributions must be in an amount at least equal to the employee’s contribution. The Swiss Plan's assets are comprised of an insurance contract that has a fair value consistent with its contract value based on the practicability exception using Level 3 inputs. The entire liability is listed as non-current because plan assets are greater than the expected benefit payments over the next year. The Company recognized pension expense related to the Swiss Plan of $0.8 million, $2.0 million and $2.4 million reflected as a component of selling, general and administrative expenses for the years ended December 31, 2022, 2021 and 2020, respectively.

The funded status of the Swiss Plan is as follows:

	Year Ended December 31,
	2022		2021
Change in Plan Assets:
Fair value of plan assets, beginning of period	$	29.3	$	27.6
Employer contributions	1.5		1.4

Funded status, end of period	$	(7.9)	$	(17.5)
Accumulated benefit obligation, end of period	$	34.0	$	41.8

Components of net periodic pension cost incurred during the years ended December 31, 2022, 2021 and 2020 are as follows:

	Year Ended December 31,
	2022		2021		2020
Service cost	$	1.9	$	2.4	$	1.9
Interest cost	0.1		—		0.1

Amortization of loss	0.1		0.6		0.2
Amortization of prior service credit	(0.1)		(0.2)		(0.2)
Settlements	(0.4)		—		1.0
Net periodic benefit cost	$	0.8	$	2.0	$	2.4

100

The weighted average assumptions used to calculate the projected benefit obligations are as follows:

	December 31, 2022		December 31, 2021
Discount rate	2.1	%	0.3	%
Expected rate of return	3.5	%	3.0	%
Rate of future compensation increases	1.8	%	1.4	%

The overall expected long-term rate of return on assets assumption considers historical returns, as well as expected future returns based on the fact that investment returns are insured, and the legal minimum interest crediting rate as applicable. Total contributions expected to be made into the plan for the year-ended December 31, 2023 is $1.6 million.

The following table presents gains (losses) recognized in accumulated other comprehensive income (loss) before income tax related to the Company’s defined benefit pension plans:

	Year Ended December 31,
	2022		2021
Net actuarial gain	$	9.0	$	5.9
Prior service cost	(0.3)		(1.3)
Total recognized in other comprehensive income (loss)	$	8.7	$	4.6

Future benefits expected to be paid as of December 31, 2022 are as follows:

Year	As of December 31, 2022
2023	$	1.8
2024	1.8
2025	2.0
2026	1.9
2027	2.1
Thereafter	27.6
Total	$	37.2

401(k) savings plan

The Company has established a defined contribution savings plan under Section 401(k) of the Internal Revenue Code (the "401(k) Plan"). The 401(k) Plan covers substantially all U.S. employees. Under the 401(k) Plan, employees may make elective salary deferrals. During the years ended December 31, 2022, 2021 and 2020, the Company made matching contributions of approximately $8.8 million, $8.9 million and $6.6 million, respectively.

16. Purchase commitments

Purchase commitments are agreements to purchase raw materials and services that are enforceable, legally binding, and specify terms that (1) include fixed or minimum quantities to be purchased, (2) include fixed, minimum or variable price provisions and (3) are longer than one year.

As of December 31, 2022 the Company has approximately $132.8 million of purchase commitments associated with raw materials and CDMO services that will be purchased in the next five years, of which the Company estimates that approximately $125.7 million will be purchased within the next year. For the years ended December 31, 2022, 2021, and 2020, the Company purchased $199.6 million, $110.7 million and $108.0 million, respectively, of materials and services under these commitments.

101

17. Segment information

The Company reports segment information based on the internal reporting used by management for making decisions and assessing performance. During the first quarter of 2022, the Company revised the reporting that the CODM reviews in order to assess Company performance. The CODM manages the business with a focus on two reportable segments: (1) Products segment consisting of the Government - MCM and Commercial product categories and (2) Services segment focused on CDMO services. The Company evaluates the performance of these reportable segments based on revenue and Adjusted Gross Margin, which is a non-GAAP financial measure. Segment revenue includes external customer sales, but it does not include inter-segment services. The Company defines Adjusted Gross Margin as segment revenue less segment cost of sales reduced for significant events, inventory step-up provisions and changes in fair value of contingent consideration. The Company does not allocate research and development, selling, general and administrative costs, amortization of intangibles assets, interest and other income (expense) or taxes to operating segments in the management reporting reviewed by the CODM. The accounting policies for segment reporting are the same as for the Company as a whole. The Company has recast the related historical information for consistency.

The Company manages its assets on a total company basis, not by operating segment, as the Company's operating assets are shared or commingled. Therefore, the Company's CODM does not regularly review any asset information by operating segment and, accordingly, the Company does not report asset information by operating segment.

102

The following table includes segment revenues and a reconciliation of the Company's segment adjusted gross margin to the consolidated statement of operations for each of the Company's reporting segments:

18. Litigation

Securities and shareholder litigation

With respect to the specific legal proceedings and claims described below, unless otherwise noted, the amount or range of possible losses is not reasonably estimable. There can be no assurance that the settlement, resolution, or other outcome of one or more matters, including the matters set forth below, during any subsequent reporting period will not have a material adverse effect on the Company's results of operations or cash flows for that period or on the Company's financial condition.

On April 20, 2021, May 14, 2021, and June 2, 2021, putative class action lawsuits were filed against the Company and certain of its current and former senior officers in the United States District Court for the District of Maryland on behalf of purchasers of the Company’s common stock, seeking to pursue remedies under the Securities Exchange Act of 1934. These complaints were filed by Palm Tran, Inc. – Amalgamated Transit Union Local 1577 Pension Plan; Alan I. Roth; and Stephen M. Weiss, respectively. The complaints allege, among other things, that the defendants made false and misleading statements about the Company's manufacturing capabilities with respect to COVID-19 vaccine bulk drug substance (referred to herein as "CDMO Manufacturing Capabilities"). These cases were consolidated on December 23, 2021, under the caption In re Emergent BioSolutions Inc. Securities Litigation, No. 8:21-cv-00955-PWG (the "Federal Securities Class Action"). The Lead Plaintiffs in the consolidated matter are Nova Scotia Health Employees’ Pension Plan and The City of Fort Lauderdale Police & Firefighters’ Retirement System. The defendants filed a motion to dismiss on May 19, 2022 and the Lead Plaintiff filed an opposition to that motion on July 19, 2022. The defendants believe that the

104

allegations in the complaints are without merit and intend to defend the matters vigorously. Given the uncertainty of litigation, the preliminary stage of the cases, and the legal standards that must be met for, among other things, class certification and success on the merits, the Company cannot reasonably estimate the possible loss or range of loss, if any, that may result from the consolidated action.

On June 29, 2021, Lincolnshire Police Pension Fund (“Lincolnshire”), and on August 16, 2021, Pooja Sayal, filed putative shareholder derivative lawsuits in the United States District Court for the District of Maryland on behalf of the Company against certain of the Company's current and former officers and directors for breach of fiduciary duties, waste of corporate assets, and unjust enrichment, each allegation related to the CDMO Manufacturing Capabilities.

The complaints seek monetary and punitive damages. On February 22, 2022, the Court entered an order consolidating these actions under case number C-15-21-CV-000496. On March 9, 2022, the parties filed a Joint Stipulation of Stay of Proceedings and Discovery, pursuant to which the parties agreed to stay all proceedings until 30 calendar days after a ruling on the defendants’ motion to dismiss the Federal Securities Class Action.

2023 Organizational Restructuring Plan

On January 9, 2023, the Company announced an organizational restructuring plan (the “Plan”) intended to reduce operating costs, improve operating margins, and continue advancing the Company’s ongoing commitment to profitable growth. The Plan includes a reduction of the Company’s current workforce by approximately five percent. Decisions regarding the elimination of positions are subject to local law and consultation requirements in certain countries, as well as the Company’s business needs.

The Company estimates that it will incur approximately $9.0 million to $11.0 million in charges in connection with the Plan, which it expects to incur in the first quarter of fiscal 2023. These charges consist primarily of charges related to employee transition, severance payments, employee benefits, and share-based compensation.

Agreement to Sell Travel Business

On February 15, 2023, we entered into the Sale Agreement with Bavarian Nordic, under which we agreed to sell our travel health business, including rights to Vaxchora and Vivotif, as well as our development-stage chikungunya vaccine candidate CHIKV VLP, our manufacturing site in Bern, Switzerland and certain of our development facilities in San Diego, California for a cash purchase price of $270.0 million, subject to certain customary adjustments. In addition, we may receive milestone payments of up to $80.0 million related to the development of CHIKV VLP and receipt of marketing approval and authorization in the U.S. and Europe, and sales-based milestones payments of up to $30.0 million based on aggregate net sales of Vaxchora and Vivotif in calendar year 2026. Approximately 280 employees are expected to join Bavarian Nordic as part of the transaction.

The transaction is expected to close in the second quarter of 2023, subject to certain customary closing conditions, including (1) the expiration or earlier termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (2) receipt of required clearances and approvals under Spain’s competition laws, (3) receipt of certain Swiss real property approvals, (4) no material adverse effect having occurred with respect to the Business, and (5) certain other customary conditions.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2022. The term "disclosure controls and procedures," as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company's management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2022, at the time the Original Form 10-K was filed, our chief executive officer and chief financial officer concluded that, as of such date, that the disclosure controls and procedures were not effective due to a material weakness in internal control over financial reporting related to the Company's inventory process. As a result of the subsequently identified material weakness in internal control over financial reporting associated with accounting for state income taxes that is described below and elsewhere in this Amendment, our chief executive officer and chief financial officer reaffirmed their prior conclusion that our disclosure controls and procedures were ineffective as of December 31, 2022 due to these identified material weaknesses.

Management's Report on Internal Control Over Financial Reporting (Restated)

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

At the time the Original Form 10-K was filed and as of the date of this Amendment, our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2022. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013 Framework). As a result of these assessments, our management concluded that, as of December 31, 2022, our internal control over financial reporting was not effective due to an identified material weakness related to the improper capitalization of inventory. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

More specifically, the material weakness related to capitalization of inventory is due to insufficient controls related to our assessment of pre-launch materials meeting the criteria for capitalization, which requires those materials to have economic value and a high probability of regulatory approval.

Subsequent to management's assessment of internal control over financial reporting at the time the Original 10-K was filed, management identified a second material weakness related to the design of our controls associated with the review of the calculation of our state deferred tax assets and liabilities and the operating effectiveness of the controls associated with the review of the valuation allowance calculation. As discussed in the Explanatory Note to this Amendment and Note 2 to the Consolidated Financial Statements contained in Part II, Item 8, “Financial Statements and Supplementary Data,” this material weakness resulted in the restatement of the Consolidated Financial Statements as of, and for the year ended, December 31, 2022.

Ernst & Young LLP, the independent registered public accounting firm that has audited our consolidated financial statements included herein, has issued an attestation report on the effectiveness of our internal control over financial reporting as of December 31, 2022, a copy of which is included in this Amendment.

109

Remediation

Inventory

We have initiated implementing measures designed to improve our internal control over financial reporting related to the capitalization of inventory, including documenting a formal policy on the accounting for pre-paunch materials purchased for use in R&D activities, providing additional training related to the new policy, implementing a monthly control to review pre-launch inventory with corporate finance to ensure proper accounting treatment. As a result of these efforts and given that the deficiencies relate to specific adjustments that were made during the period ended December 31, 2022, we believe that the Inventory Capitalization Issue has been remediated during the first quarter of 2023.

State Income Taxes

As part of our commitment to strengthening our internal control over financial reporting, we are implementing remedial actions under the oversight of the Audit Committee of our board of directors to address these deficiencies, including:

•Enhanced review and reconciliation procedures

•Additional training on the affected tax matters

We will continue to monitor the design and operating effectiveness of these and other processes, procedures and controls and make any further changes management determines appropriate.

Changes in Internal Control Over Financial Reporting

Except for the material weaknesses described above, there has been no change in the Company's internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) that occurred during the quarter ended December 31, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Emergent BioSolutions Inc.

Opinion on Internal Control over Financial Reporting

We have audited Emergent BioSolutions Inc. and subsidiaries’ internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, because of the effect of the material weaknesses described below on the achievement of the objectives of the control criteria, Emergent BioSolutions Inc. and subsidiaries (the Company) has not maintained effective internal control over financial reporting as of December 31, 2022, based on the COSO criteria.

In our report dated March 1, 2023, we expressed an adverse opinion that the Company had not maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on the COSO criteria, as a result of a material weakness in controls related to the Company's inventory process. Management has subsequently identified deficiencies related to the design of controls associated with the review of the calculation of state deferred tax assets and liabilities and the operating effectiveness of the controls associated with the review of the valuation allowance calculation, and has further concluded that such deficiencies represented a material weakness as of December 31, 2022. As a result, management has revised its assessment, as presented in the accompanying Management's Annual Report on Internal Control over Financial Reporting, to include the subsequently identified material weakness that existed as of December 31, 2022. Accordingly, our present opinion on the effectiveness of internal control over financial reporting as of December 31, 2022, as expressed herein includes an additional material weakness from our previous report.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weaknesses have been identified and included in management’s assessment. Management has identified a material weakness in controls related to the Company's inventory process. Management also has identified a material weakness in controls related to the state income tax process as described above.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2022 and 2021, the related consolidated statements of operations, comprehensive income (loss), changes in stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2022, and the related notes and financial statement schedule listed in the Index at Item 15. These material weaknesses were considered in determining the nature, timing and extent of audit tests applied in our audit of the 2022 consolidated financial statements, and this report does not affect our report dated March 1, 2023, except for the effect of the restatement disclosed in Note 2, as to which the date is December 11, 2023, which expressed an unqualified opinion that included an explanatory paragraph regarding the Company's ability to continue as a going concern.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

111

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
