Discontinued Operations and Disposal Groups [Abstract]
Divestiture	Divestiture On May 15, 2023, pursuant to the Purchase and Sale Agreement (the “Purchase and Sale Agreement”), by and between the Company, through its wholly owned subsidiaries Emergent International Inc. and Emergent Travel Health Inc., and Bavarian Nordic ("Bavarian Nordic”), the Company completed the previously announced sale of the Company’s travel health business, including rights to Vivotif®, the licensed typhoid vaccine; Vaxchora®, the licensed cholera vaccine; the development-stage chikungunya vaccine candidate CHIKV VLP; the Company’s manufacturing site in Bern, Switzerland; and certain of its development facilities in San Diego, California. At the closing, Bavarian Nordic paid a cash purchase price of $270.0 million, exclusive of customary closing adjustments for cash, indebtedness, working capital and transaction expenses of the business at closing. Bavarian Nordic may also be required to pay 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 earn-out payments of up to $30.0 million based on aggregate net sales of Vaxchora and Vivotif in calendar year 2026. As a result of the divestiture, during the nine months ended September 30, 2023, the Company recognized a pre-tax gain of $74.2 million, net of transaction costs of $4.0 million recorded within "Gain on sale of business" on the Condensed Consolidated Statements of Operations. During the three months ended September 30, 2023, a measurement period adjustment of $0.7 million was recognized, which reduced the gain. The reduction represents a working capital adjustment, payable to Bavarian Nordic. The Company determined that the disposal of the travel health business does not qualify for reporting as a discontinued operation since it does not represent a strategic shift that has or will have a major effect on our operations and financial results. No adjustments were made to prior period results as a result of the disposal. In connection with the divestiture, the Company entered into a Transition Services Agreement (“TSA”) with Bavarian Nordic to help support its ongoing operations. Under the TSA, the Company provides certain transition services to Bavarian Nordic, including information technology, finance and enterprise resource planning, research and development, human resources, employee benefits and other limited services. Income from performing services under the TSA was recorded within "Other, net" on the Condensed Consolidated Statements of Operations and was $1.2 million and $2.2 million for the three and nine months ended September 30, 2023, respectively.

Fair Value Disclosures [Abstract]

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 indicates the level within the fair value hierarchy of the valuation techniques the Company utilized to determine fair value:

Contingent consideration

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 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 on the Company's Condensed Consolidated Statement of Operations as "Cost of product sales."

The table below is a reconciliation of the beginning and ending balance of the Company's Level 3 contingent consideration liability:


	Contingent Consideration
Balance at December 31, 2022 (As Restated)	$	8.0
Change in fair value	0.3
Settlements	(0.7)
Balance at March 31, 2023	$	7.6
Change in fair value	0.4
Settlements	(0.6)
Balance at June 30, 2023	$	7.4
Change in fair value	(1.1)
Settlements	(0.9)
Balance at September 30, 2023	$	5.4

As of September 30, 2023 and December 31, 2022, the current portion of the contingent consideration liability was $2.1 million and $3.4 million, respectively, and was included in "Other current liabilities" on the Condensed Consolidated Balance Sheets. The non-current portion of the contingent consideration liability is included in "Other liabilities" on the Condensed Consolidated Balance Sheets.

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

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 10, "Debt").

Accounting Policies [Abstract]

Summary of significant accounting policies

Basis of presentation and consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of Emergent and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The unaudited condensed consolidated financial statements included herein have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X issued by the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in Amendment No. 1 to the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022, as filed with the SEC on December 11, 2023.

In connection with the 2022 adjustments described in Note 18, “Adjustments to quarterly financial data”, there were immaterial adjustments, both individually and in the aggregate, that impacted the Company’s 2023 quarterly filings for the periods ended March 31, 2023 and June 30, 2023. All other adjustments contained in the accompanying unaudited condensed consolidated financial statements are of a normal recurring nature and are necessary to present fairly the financial position of the Company as of September 30, 2023. Interim results are not necessarily indicative of results that may be expected for any other interim period or for an entire year.

Going concern

As of September 30, 2023, there is $211.2 million outstanding on the Company's Revolving Credit Facility and $202.1 million on Term Loan Facility that matures in May 2025. 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. This evaluation considered the mitigating effect of management’s plans that have been implemented as of September 30, 2023. 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 plans include (A) amending the agreement for the Senior Secured Credit Facilities, which occurred on May 15, 2023, with the Fourth Amendment to Amended and Restated Credit Agreement, Waiver and First Amendment to Amended and Restated Collateral Agreement (the “Credit Agreement Amendment”), and (B) the execution of the capital raise requirement prescribed in the Credit Agreement Amendment, as further described below.

While the Company executed the Credit Agreement Amendment and extended the maturity date on the Senior Secured Credit Facilities to May 15, 2025, the Credit Agreement Amendment also requires the Company maintain a minimum consolidated EBITDA through February 29, 2024 and to raise at least $75.0 million through the issuance of equity and/or unsecured indebtedness by April 30, 2024. As a result of these provisions, the Company has determined it is appropriate to continue to classify the debt as a current liability on the Condensed Consolidated Balance Sheets. Additional information on the nature and status of our debt covenant compliance is included below.

Debt Covenants

The Company has a senior secured credit facility that matures in May 2025 (the “Credit Facility”) which provides for (1) revolving credit commitments, (2) a term loan, and (3) the issuance of commercial letters of credit. As of September 30, 2023, we had $413.3 million outstanding under the Credit Facility. Under the Credit Facility, the Company is subject to a monthly minimum consolidated EBITDA covenant through February 29, 2024 and is also required to raise at least $75.0 million through the issuance of equity and/or unsecured indebtedness by April 30, 2024. As of September 30, 2023, we were in compliance with all of the covenants and restrictions associated with, and no events of default existed under, the Credit Facility. However, based on the timing of the USG procurement of the remaining 2023 order for CYFENDUSTM and a number of other product sales through the end of 2023, the Company anticipates that, absent a cure or waiver, it may be in breach of the minimum consolidated EBITDA covenant as early as the reporting date for the measurement period ending December 31, 2023. In the event the Company remains in compliance with the minimum consolidated EBITDA covenant through the measurement period ending December 31, 2023, the Company anticipates that, absent a cure or waiver of the minimum consolidated EBITDA covenant, it may be in breach of the minimum consolidated EBITDA covenant as early as the reporting date for the measurement period ending February 29, 2024. In addition, the Company is required to deliver audited annual financial statements without a “going concern” or like qualification or exception with respect to our financial statements for the year ended December 31, 2023 within 90- days of year end. The Credit Facility and the Company’s other debt facilities are described in more detail below in Note 10, “Debt” and in Note 9, “Debt” in Amendment No. 1 to the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

If the Company is not compliant with the covenants an event of default may occur under the Credit Facility and the agent and requisite lenders thereunder could take actions to exercise certain rights and remedies as described in the Credit Facility. Further, acceleration of the Credit Facility would result in a cross-default of the Company’s obligations under the 3.875% Senior Unsecured Notes due in 2028. If the Company would be unable to obtain a waiver or forbearance of such covenants or defaults, to successfully renegotiate the terms of the Credit Facility, or to cure the potential covenant breach or default, and the lenders enforced one or more of their rights upon default and/or the default resulted in a cross-default under certain other of the Company’s debt instruments, the Company would be unable to meet its obligations and could be forced into insolvency proceedings.

Based on the facts and circumstances described above, management cannot make the assumption that it is probable that these debt covenants will be met. As a result, the Company continues to evaluate a number of uncertain factors related to its assessment of its ability to satisfy the capital raise requirement, including its ability to comply with the terms and operating and financial covenants required by the Senior Secured Credit Facilities, other market conditions, economic conditions, particularly in the pharmaceutical and biotechnology industry, and disruptions or volatility caused by factors such as regional conflicts, inflation, and supply chain disruptions. The Company has engaged legal and financial advisors to assist with a comprehensive review of alternatives to enhance its capital structure, which may include taking steps to cure any potential defaults or seeking forbearance, waivers, further cost reductions or other alternatives to avoid an event of default.

The Condensed Consolidated Financial Statements have been prepared assuming the Company will continue as a going concern. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Revenue recognition

Beginning in the third quarter of 2023, the Company launched the over-the-counter NARCAN® (naloxone HCl) Nasal Spray, 4mg (“NARCAN® OTC”), which was approved by the FDA as an over-the-counter emergency treatment of opioid overdose, broadening our customer base and sales channels to retail pharmacies and digital commerce websites. Refer to Note 13, "Revenue recognition" for more information regarding revenue recognition accounting policies related to NARCAN® OTC product sales.

Pre-launch inventory

Within the Company's Products segment, costs relating to raw materials and production of inventory in preparation for product launch prior to regulatory approval are capitalized when the review process has progressed to a point where objective and persuasive evidence exists that regulatory approval is probable, the future economic benefit is expected to be realized, and the Company believes that material uncertainties related to the ultimate regulatory approval have been significantly reduced. Pre-launch inventory is recorded to research and development expense unless these criteria are met. For pre-launch inventory that is capitalized, the Company considers a number of specific facts and circumstances, including the product candidate’s current status in the drug development and regulatory approval process, results from related clinical trials, results from meetings with relevant regulatory agencies prior to the filing of regulatory applications, potential obstacles to the approval process, historical experience, viability of commercialization and market trends. This policy is not applicable to pre-launch inventory purchased to satisfy a performance obligation related to a CDMO contract as CDMO pre-launch inventory may be capitalized if it has future economic benefit based on the terms of the contract.

Significant accounting policies

With the exception of the policies on revenue recognition and pre-launch inventory discussed above, there have been no significant changes to the Company's summary of significant accounting policies during the nine months ended September 30, 2023, contained in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022, that have materially impacted the presentation of the Company's financial statements.

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, includes:


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.

New accounting standards

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board that the Company adopts as of the pronouncement's specified effective date. There were no new accounting pronouncements that were issued or became effective since the issuance of the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 that had, or are expected to have, a material impact on its consolidated financial position, results of operations or cash flows.

Income taxes	9 Months Ended
Income taxes	Sep. 30, 2023
Income Tax Disclosure [Abstract]
Income taxes	Income taxes The estimated effective annual tax rate as of September 30, 2023 and 2022 for the years ended December 31, 2023 and 2022, excluding the impact of discrete adjustments, was (5)% and 4%, respectively. The decrease in the estimated effective annual tax rate is primarily due to valuation allowance and goodwill impairment charges. The Company recorded a discrete tax expense (benefit) of $1.0 million and $1.0 million for the three and nine months ended September 30, 2023, respectively, and $(9.0) million and $(7.3) million for the three and nine months ended September 30, 2022, respectively. The discrete tax expense in 2023 was due to return-to-provision adjustments and share-based compensation activity which was entirely offset by a valuation allowance charge. The discrete benefit in 2022 was primarily due to return-to-provision adjustments and the benefit of the release of an indemnified uncertain tax position offset by share-based compensation activity. 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. At each reporting period, the Company considers the scheduled reversal of deferred tax liabilities and assets, available taxes in carryback periods, tax planning strategies and projected future taxable income in making this assessment. In 2022, the Company determined that it was more likely than not that certain deferred tax assets would not be realized due to reductions in estimates of future profitability and disclosure related to substantial doubt about the Company's ability to continue as a going concern. Accordingly, the Company recorded an additional valuation allowance charge of $163.1 million in calculating the estimated annual tax rate for the year ended December 31, 2023.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

(1) As of September 30, 2023, excludes the unamortized debt issuance costs related to the revolver loan which are included within "Other current assets" on the accompanying Condensed Consolidated Balance Sheet.

During the second quarter of 2023, the Company reclassified the debt issuance costs associated with the revolver loan to "Other current assets." Prior to the second quarter of 2023, the debt issuance costs associated with the revolver loan were classified as a direct offset to the carrying value of the debt within "Other current liabilities." As of September 30, 2023 and December 31, 2022, the Company had $9.4 million and $1.3 million of debt issuance costs associated with the revolver loan, 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% 2028 Notes. Interest on the 2028 Notes is payable on February 15th and August 15th of each year until maturity, beginning on February 15, 2021. The 2028 Notes will mature on August 15, 2028.

As of August 15, 2023, the Company may redeem the 2028 Notes, in whole or in part, at the redemption prices set forth in the related indenture, plus accrued and unpaid interest. As of August 15, 2023, the Company may redeem all or a portion of the 2028 Notes at a redemption price equal to 100% of the principal amount of the 2028 Notes plus a “make-whole” premium and accrued and unpaid interest as set forth in the related indenture. Upon the occurrence of a change of control, the Company must offer to repurchase the 2028 Notes at a purchase price of 101% of the principal amount of such 2028 Notes plus accrued and unpaid interest.

Negative covenants in the indenture governing the 2028 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 Facilities

On May 15, 2023, the Company entered into the Credit Agreement Amendment. The Credit Agreement Amendment amended the Existing Credit Agreement to, among other things, (a) extend the maturity date of the Senior Secured Credit Facilities from October 13, 2023 to May 15, 2025, (b) reduce the available commitments under the Revolving Credit Facility from $600.0 million to $300.0 million, (c) remove the Company's ability to incur incremental loans and (d) amend certain mandatory prepayment triggers, affirmative covenants, negative covenants and events of default thereunder. In connection with the Credit Agreement Amendment, the Company used the approximately $270.0 million of proceeds from the sale of its travel health business to Bavarian Nordic, which closed on May 15, 2023, together with approximately $217.2 million of cash on hand, to repay approximately $144.4 million in outstanding principal amount of loans under the Term Loan Facility and $342.8 million outstanding principal amount of loans under the Revolving Credit Facility. The Credit Agreement Amendment also requires that the Company make quarterly principal payments on the Term Loan Facility of approximately $3.9 million, which commenced on June 30, 2023 and will extend through March 31, 2025.

The Credit Agreement Amendment also (w) amended the consolidated debt service coverage ratio financial covenant to require the minimum level to be 2.25 to 1.00 for the fiscal quarters ending March 31, 2024, June 30, 2024, September 30, 2024 and December 31, 2024, and then 2.50 to 1.00 for each fiscal quarter ending thereafter, (x) amended the consolidated leverage ratio to require the maximum level to be 4.50 to 1.00 for the fiscal quarter ending March 31, 2024 and each fiscal quarter ending thereafter, (y) added minimum Consolidated EBITDA requirements and maximum capital expenditure requirements for each of the months ending April 30, 2023 through February 29, 2024 and a minimum liquidity requirement as of the end of each calendar month and (z) requires the Company to increase its liquidity by April 30, 2024 by raising at least $75.0 million of equity or unsecured indebtedness.

In addition, the Credit Agreement Amendment replaced the interest rate benchmark such that borrowings under the Revolving Credit Facility and the outstanding principal amount of the Term Loan Facility shall bear interest at a rate per annum equal to (a) a rate based on SOFR, EURIBOR or CDOR plus a margin of 6.00% until March 31, 2024 and thereafter, a margin ranging from 2.75% to 4.00% depending on the Company’s consolidated leverage ratio, or (b) a base rate (which is the highest of the prime rate, the federal funds rate plus 0.50%, and a SOFR rate for an interest period of one month plus 1%) plus a margin of 5.00% until March 31, 2024 and thereafter, a margin ranging from 1.75% to 3.00% depending on the Company’s consolidated leverage ratio. In addition, the commitment fee the Company is required to pay in respect of the annual daily unused commitments under the Revolving Credit Facility shall be 0.15% to 0.40% per annum, depending on the Company’s consolidated leverage ratio.

Under the Credit Agreement Amendment, the Company and the other guarantors also agreed to provide a lien over certain assets as additional collateral for the benefit of the lenders, including owned real property, equity interests of foreign subsidiaries and certain deposit accounts.

- Definition

Derivative Instruments and Hedging Activities Disclosure [Abstract]

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. From time to time, the Company enters into interest rate swap transactions to manage exposures that arise from payments of variable interest rate debt associated with the Company's senior secured credit agreements. The objective and strategy with respect to these interest rate swaps is to protect the Company against adverse fluctuations in interest rates.

During the second quarter of 2023, the Company terminated its designated interest rate swap transactions with a total notional value of $350.0 million. Hedge accounting was also discontinued at that time. As of September 30, 2023, the remaining accumulated other comprehensive income associated with the terminated interest rate swaps, before tax, was $0.5 million and will be amortized to earnings over the remaining term of the interest rate swaps prior to termination.

The table below presents the fair value of the Company’s derivative financial instruments designated as hedges as well as their classification on the Condensed Consolidated Balance Sheets:


		Fair Value of Asset Derivatives
	Classification	September 30, 2023		December 31, 2022
Interest Rate Swaps	Other Current Assets	$	—	$	8.5

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.

Segment Reporting [Abstract]

Segment information

The Company reports segment information based on the internal reporting used by management for making decisions and assessing performance. We manage our business with a focus on two reportable segments. Our Products segment, which includes the Anthrax - MCM products, NARCAN® products, Smallpox - MCM products and Other products, and our Services segment consisting of our 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 restructuring 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 chief operating decision maker ("CODM"). The accounting policies for segment reporting are the same as for the Company as a whole.

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.

Adjustments to quarterly financial data

Accounting Changes and Error Corrections [Abstract]

Adjustments to quarterly financial data

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. Refer to Amendment No. 1 to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, filed with the Securities and Exchange Commission on December 11, 2023 for more information regarding the restatement of the consolidated financial statements for the fiscal year ended December 31, 2022, contained in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022 (the “Original Form 10-K”). Due to the use of incorrect state tax rates in the calculation of state deferred tax assets and related valuation allowances along with other individually immaterial adjustments affecting the period, the Company understated the income tax provision by $8.1 million and $1.7 million for the three and nine months ended September 30, 2022. As a result, the Company determined to restate its interim financial statements for the three and nine months ended September 30, 2022. In addition to adjustments that impacted the Company’s financial statements for the fiscal year ended December 31, 2022, and interim financial statements as of and for the three and nine months ended September 30, 2022, there were other immaterial adjustments, both individually and in the aggregate, that impacted the Company’s 2023 quarterly filings for the periods ended March 31, 2023 and June 30, 2023.

The tables below present the impact of the financial statement adjustments on the Company's previously reported Condensed Consolidated Balance Sheets as of September 30, 2022 and December 31, 2022, the Condensed Consolidated Statement of Operations for the three and nine months ended September 30, 2022 and the Condensed Consolidated Statement of Cash Flows for the nine months ended September 30, 2022. The "Previously Reported" amounts in the following tables are amounts derived from the Original Form 10-K or the Quarterly Report on Form 10-Q for the applicable period. The amounts in the columns labeled "Tax Adjustments" represent the effect of adjustments resulting from the correction of the misstatement of the Company’s net state deferred tax liability and the income tax benefits and includes the tax impact of all other individually immaterial non-tax adjustments. The amounts in the columns labeled "Other Adjustments" represent the effect of correcting other unrelated errors that were previously recognized as out-of-period adjustments in previously filed financial statements that were not material, individually or in the aggregate, to those financial statements. The effects of the restatement and immaterial revisions have been corrected in all impacted tables and footnotes throughout these condensed consolidated financial statements. consolidated financial statements.

Summary of significant accounting policies (Policies)

Accounting Policies [Abstract]

Basis of presentation and consolidation

Revenue recognition

The Company's NARCAN® OTC customer contracts are fixed price contracts. The Company invoices and records revenue when the pharmacies and wholesalers receive product from the third-party logistics warehouse used by the Company, which is the point at which control is transferred to the customer. Revenues for NARCAN® OTC are recorded at the net sales price (transaction price), which includes estimates of variable consideration for which reserves are established. Estimates of variable consideration includes allowance for returns, specialty distributor fees, wholesaler fees and prompt payment discounts. Revenues from NARCAN® OTC are 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. The Company considers several factors in the estimation process for the allowance for returns of NARCAN® OTC, including inventory levels within the distribution channel, product shelf life and historical return activity, including activity for product sold for which the return period has passed, as well as other relevant factors. Because returned product cannot be resold, there is no corresponding asset for product returns.

Pre-launch inventory

Fair value measurements


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.

Litigation	9 Months Ended
Litigation	Sep. 30, 2023
Commitments and Contingencies Disclosure [Abstract]
Litigation	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 (the "Lead Plaintiffs") 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 Plaintiffs filed an opposition to that motion on July 19, 2022. A hearing on the motion to dismiss was conducted on April 19, 2023 and an order was entered on September 1, 2023, granting in part and denying in part the motion to dismiss. The defendant's answer to the complaint was filed on October 30, 2023. The defendants believe that the 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. In addition to monetary damages, the complaints seek the implementation of multiple corporate governance and internal policy changes. On November 16, 2021, the cases were consolidated under the caption In re Emergent BioSolutions Inc. Stockholder Derivative Litigation, Master Case No. 8:21-cv-01595-PWG. On January 3, 2022, the Lincolnshire complaint was designated as the operative complaint in the consolidated action. On April 13, 2022 the Court approved the parties' joint stipulation to and stay of the proceedings and discovery until the close of fact discovery in the Federal Securities Class Action. The defendants believe that the allegations in the complaints are without merit and intend to defend the matter vigorously. On September 15, 2021, September 16, 2021 and November 12, 2021, putative shareholder derivative lawsuits were filed by Chang Kyum Kim, Mark Nevins and Employees Retirement System of the State of Rhode Island, North Collier Fire Control and Rescue District Firefighters Pension Plan, and Pembroke Pines Firefighters & Police Officers Pension Fund, respectively, in the Court of Chancery of the State of Delaware on behalf of the Company against certain of its current and former officers and directors for breach of fiduciary duties, unjust enrichment and insider trading, each allegation related to the CDMO Manufacturing Capabilities. In addition to monetary damages, the complaints seek the implementation of multiple corporate governance and internal policy changes. On February 2, 2022, the cases were consolidated under the caption In re Emergent BioSolutions, Inc. Derivative Litigation, C.A. No. 2021-0974-MTZ with the institutional investors as co-lead plaintiffs. On March 4, 2022, the defendants’ filed a motion to dismiss the complaint. Ruling on this motion is stayed pursuant to a March 29, 2022 order staying all proceedings pending a final, non-appealable judgment in the Federal Securities Class Action. On December 3, 2021, December 22, 2021 and January 18, 2022, putative shareholder derivative lawsuits were filed by Zachary Elton, Eric White and Jeffrey Reynolds in the Circuit Court for Montgomery County, Maryland on behalf of the Company against certain of its current and former officers and directors for breach of fiduciary duty, unjust enrichment, waste of corporate assets, failing to maintain internal controls, making or causing to be made false and/or misleading statements and material omissions, insider trading and otherwise violating the federal securities laws, 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, and on November 2, 2023 the Court approved the parties' joint stipulation to extend the stay of the proceedings and discovery until the close of fact discovery in the Federal Securities Class Action. In addition to the above actions, the Company has received inquiries and subpoenas to produce documents related to these matters from the Department of Justice, the SEC, the Maryland Attorney General’s Office, and the New York Attorney General’s Office. The Company produced or is producing documents as required in response and will continue to cooperate with these government inquiries. The Company also received inquiries and subpoenas from Representative Carolyn Maloney and Representative Jim Clyburn, members of the House Committee on Oversight and Reform and the Select Subcommittee on the Coronavirus Crisis and Senator Murray of the Committee on Health, Education, Labor and Pensions. The Company produced documents and provided testimony and briefings as requested in response to these inquiries.

Stockholders' Equity Note [Abstract]

Stock-based compensation and stockholders' equity

Stock-based compensation

During the nine months ended September 30, 2023, the Company granted stock options to purchase 0.8 million shares of common stock, 1.6 million restricted stock units and 0.5 million performance stock units under the Emergent BioSolutions Inc. Amended and Restated Stock Incentive Plan. Performance stock units are presented at the target payout percentage of 100% of target shares granted and the maximum potential payout percentage is up to 200% of target shares granted. Typically, the stock options and restricted stock unit grants vest over three equal annual installments beginning on the day prior to the anniversary of the grant date. The performance stock units settle in stock at the end of the three-year performance period based on the Company's results compared to the performance criteria. During the nine months ended September 30, 2023, 0.9 million of stock options and 0.7 million shares of restricted stock units were forfeited prior to the completion of the applicable vesting requirements or expiration. Additionally, 0.3 million performance stock units were forfeited during the nine months ended September 30, 2023, as the award targets or vesting requirements were not achieved.

Stock-based compensation expense, net of forfeitures was recorded in the following financial statement line items:

At-the-Market Equity Offering Facility

We may, from time to time, sell up to $150.0 million aggregate gross sales price of shares of our common stock through Evercore Group L.L.C. and RBC Capital Markets, LLC, as sales agents, under an “at-the-market” equity offering program (the “ATM Program”) that we entered into on May 18, 2023. There were no sales of our common stock under the ATM Program during the three months ended September 30, 2023. Between the entry into the ATM Program and September 30, 2023, we sold 1.1 million shares of our common stock under the ATM Program for gross proceeds of $9.1 million, representing an average share price of $8.22 per share. As of September 30, 2023, $140.9 million aggregate gross sales price of shares of our common stock remains available for issuance under the ATM Program. We intend to use proceeds obtained from the sale of shares under the ATM Program for general corporate purposes.

2023 Inducement Plan

On September 28, 2023, the Company's Board of Directors adopted and approved the Emergent BioSolutions, Inc. Inducement Plan (the "Inducement Plan"), pursuant to which the Company may from time to time make equity grants to individuals not previously an employee or director of the Company or any of its subsidiaries (or following a bona fide period of interruption of employment) as a material inducement to their employment by the Company. The Inducement Plan was adopted by the board of directors without stockholder approval pursuant to New York Stock Exchange Listing Rule 303A.08. The board of directors reserved 5,000,000 shares of the Company's common stock for issuance under the Inducement Plan. The terms and conditions of the Inducement Plan are substantially similar to the Company's stockholder-approved Emergent BioSolutions Inc. Amended and Restated Stock Incentive Plan. As of September 30, 2023, no shares had been issued under the Inducement Plan.

2021 Share 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 "2021 Share Repurchase Program"), of which $187.9 million was utilized to purchase approximately 4.4 million shares. The 2021 Share Repurchase Program expired on November 11, 2022. During the three months ended September 30, 2022, there were no shares repurchased. During the nine months ended September 30, 2022, the Company utilized $75.5 million to purchase approximately 1.8 million shares. The 2021 Share Repurchase Program did not obligate the Company to acquire any specific number of shares. Repurchased shares are available for use in connection with the Company's stock plans and for other corporate purposes.

Goodwill and Intangible Assets Disclosure [Abstract]

Intangible assets and goodwill

The Company's finite-lived intangible assets consist of products acquired via business combinations or asset acquisitions. The following table summarizes the Company's finite-lived intangible assets:


	Weighted Average Useful Life in Years	September 30, 2023						December 31, 2022
		Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount (1)		Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount
Products (2)	13.5	$	855.4	$	272.6	$	582.8	$	982.1	$	253.3	$	728.8

Total intangible assets		$	889.5	$	306.7	$	582.8	$	1,016.2	$	287.4	$	728.8

(1) During the nine months ended September 30, 2023, the Company sold $102.9 million of intangible assets, net as part of the sale of its travel health business to Bavarian Nordic. See Note 3, "Divestiture" for more information on the sale of the travel health business.
(2) During the three months ended September 30, 2023, the Company recorded a $6.3 million intangible asset addition related to the contingent consideration payment to Ridgeback for the award of a 10-year contract by the Biomedical Advanced Research and Development Authority for advanced development, manufacturing scale-up, and procurement of EbangaTM treatment for Ebola. The related intangible asset was acquired through an asset acquisition that was completed in 2022.

Amortization expense associated with the Company's intangible assets was recorded as follows:


	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Amortization expense	$	16.3	$	14.0	$	49.4	$	42.0

The table below summarizes the changes in the carrying amount of goodwill by reportable segment:


	Products (1)		Services (2)		Total



Balance at December 31, 2022	$	218.2	$	—	$	218.2
Goodwill impairment	(218.2)		—		(218.2)

Balance at September 30, 2023	$	—	$	—	$	—

(1) Amounts for the Company's Products segment include gross carrying values of $259.9 million as of September 30, 2023 and December 31, 2022 and accumulated impairment losses of $259.9 million.

(2) Amounts for the Company's Services segment include gross carrying values of $6.7 million as of September 30, 2023 and December 31, 2022, and accumulated impairment losses of $6.7 million.

The Company performs its goodwill impairment evaluation annually, during the fourth quarter, or sooner if triggering events are identified. During the three months ended September 30, 2023, the Company observed continued market volatility including significant declines in its market capitalization and revised its financial outlook during the third quarter of 2023, which was identified as a triggering event. As a result of the quantitative assessments performed in connection with the preparation of the financial statements as of and for the quarter ended September 30, 2023, the Company recorded a $218.2 million non-cash goodwill impairment charge for the MCM reporting unit within the Products segment, which is included in "Goodwill impairment" on the Condensed Consolidated Statement of Operations for the three and nine months ended September 30, 2023. The MCM reporting unit and Products segment had no remaining goodwill as of September 30, 2023. The goodwill impairment

charge resulted from a reduction in the estimated fair value of the MCM reporting unit due to changes in the risk profile of the Company as well as revisions to the long-term operating plan that reflected lower expectations for growth and profitability than previous expectations. The Company used a quantitative assessment, utilizing an income-based (discounted cash flows) approach, Level 3 non-recurring fair value measurement, for its goodwill impairment testing.

Long-lived asset impairment and restructuring charges

Restructuring and Related Activities [Abstract]

Long-lived asset impairment and restructuring charges

Impairment of long-lived assets

The Company tests its long-lived assets that are held and used for recoverability whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable.

During the second quarter of 2023, due to deterioration in performance and resulting downward revisions to our internal CDMO forecast made during the second quarter, including future expected cash flows, the Company determined there were sufficient indicators of impairment on certain asset groups within the CDMO reporting unit to require an impairment analysis. As a result, the Company performed recoverability tests on certain asset groups within the CDMO reporting unit and concluded that the impacted asset groups were not recoverable as the undiscounted expected cash flows did not exceed their carrying values.

Asset groups are written down only to the extent that their carrying value is higher than their respective fair value. The Company, with the assistance of a third-party valuation firm, applied valuation methods to estimate the fair values for each of the assets within the different asset classes. An orderly liquidation value was applied to estimate the fair value of the personal property assets and market and cost based approaches were applied to estimate the fair value of the real property assets. All of the valuation approaches applied represented Level 3 non-recurring fair value measurements. Based on this analysis, the Company allocated and recognized a non-cash impairment charge of $306.7 million during the nine months ended September 30, 2023.

The table below presents the total impairment charge by asset class for the three and nine months ended September 30, 2023:


	Three Months Ended September 30, 2023		Nine Months Ended September 30, 2023
Buildings, building improvements and leasehold improvements	$	—	$	81.5
Furniture and equipment	—		117.5
Software	—		0.3
Construction-in-progress	—		107.4

Total impairment of long-lived assets	$	—	$	306.7

January 2023 Organizational Restructuring Plan

In January 2023, the Company initiated an organizational restructuring plan (the “January 2023 Plan”) intended to reduce operating costs, improve operating margins, and continue advancing the Company’s ongoing commitment to profitable growth. As part of the January 2023 Plan, the Company reduced its workforce by approximately 125 employees. The Company made a $(0.2) million adjustment to the incurred charges in connection with the January 2023 Plan during the three months ended September 30, 2023 and incurred approximately $9.4 million in charges during the nine months ended September 30, 2023. These charges consist primarily of charges related to employee transition, severance payments and employee benefits. All activities related to the January 2023 Plan were substantially completed during the first quarter of 2023. Restructuring costs are recognized as an operating expense within the Condensed Consolidated Statement of Operations and are classified based on the Company's classification policy for each category of operating expense.

August 2023 Organizational Restructuring Plan

In August 2023, the Company initiated the August 2023 Plan intended to strengthen its core business and financial position by reducing investment in and de-emphasizing focus on its CDMO services business for future growth. As part of the August 2023 Plan, the Company reduced its workforce by approximately 400 employees. The Company incurred approximately $20.5 million in charges in connection with the August 2023 Plan during the three months ended September 30, 2023.

Revenue recognition

9 Months Ended

Sep. 30, 2023

Revenue from Contract with Customer [Abstract]

Revenue recognition

We generate the majority of our revenues through product sales to our customers. We also generate revenues through CDMO services and suite reservations for and to third parties and contracts and grants revenue. 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.

Beginning in the third quarter of 2023, the Company launched NARCAN® OTC, which was approved by the FDA as an over-the-counter emergency treatment of opioid overdose, broadening our customer base and sales channels to retail pharmacies and digital commerce websites. The Company's Nasal Naloxone Products are now sold commercially over-the-counter at retail pharmacies and digital commerce websites as well as through physician-directed or standing order prescriptions at retail pharmacies, health departments, local law enforcement agencies, community-based organizations, substance abuse centers and other federal agencies.

The Company's revenues disaggregated by operating segment and major sources for the three and nine months ended September 30, 2023 and 2022 were as follows:


	Three Months Ended September 30, 2023						Three Months Ended September 30, 2022

CDMO operating leases

Certain multi-year CDMO service arrangements with commercial 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 weighted average remaining term on the Company's operating lease components approximates 5.3 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. The Company estimates future operating lease revenues to be $0.2 million in the remainder of 2023, $0.9 million in 2024, $0.9 million in 2025, $0.9 million in 2026, $0.9 million in 2027 and $0.9 million in years beyond 2027.

Transaction price allocated to remaining performance obligations

As of September 30, 2023, the Company has future contract value on unsatisfied performance obligations of approximately $408.6 million associated with all arrangements entered into by the Company. The Company expects to recognize $400.3 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 that the Company does not currently have a contractual right to bill, to be contract assets. As of September 30, 2023 and December 31, 2022, the Company had $38.4 million and $34.8 million, respectively, of contract assets recorded within "Accounts receivable, net" on the Condensed 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 amounts allocated to those performance obligations is reflected as contract liabilities on the Condensed 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 liability balances:


	Contract Liabilities
Balance at December 31, 2022	$	31.7
Balance at September 30, 2023	$	27.9
Revenue recognized in the period from amounts included in contract liability at the beginning of the period:	$	(7.3)

As of September 30, 2023 and December 31, 2022, the current portion of contract liabilities was $22.9 million and $26.4 million, respectively, and was included in "Other current liabilities" on the Condensed Consolidated Balance Sheets.

Accounts receivable and allowance for expected credit losses

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


	September 30, 2023		December 31, 2022
			(As Restated)
Accounts receivable:
Billed	$	156.6	$	102.7
Unbilled	61.0		57.2
Allowance for expected credit losses	(1.1)		(0.7)
Accounts receivable, net	$	216.5	$	159.2

We maintain an allowance for expected credit losses, which represents the estimated aggregate amount of credit risk arising from the inability or unwillingness of specific customers to pay our fees or disputes that may affect our ability to fully collect our billed accounts receivable. We estimate the current-period provision for expected credit losses on a specific identification basis and we consider factors such as the age of the receivables balance, knowledge of the specific customers' circumstances and historical collection experience for similar customers. Accounts receivable, net of the allowance for expected credit losses, represents the amount we expect to collect. Our actual experience may vary from our estimates. At each reporting date, we adjust the allowance for expected credit losses to reflect our current estimate.

2022 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 Janssen 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 Janssen 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 Janssen Agreement and (ii) to confirm Janssen’s intent to not purchase the requisite minimum quantity of the Product pursuant to the Janssen Agreement and instead, wind-down the Janssen 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 Janssen Agreement for asserted material breaches of the Janssen 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 Janssen 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 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 Janssen 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 three months ended September 30, 2023, there were no impacts on previously recognized revenue or depreciation related to the conclusion of the Janssen Agreement. As of September 30, 2023, the Company has no billed or unbilled net accounts receivable related to the Janssen Agreement.

Beginning in the fourth quarter of 2022, because the arbitration process is expected to extend longer than one year, the Company reclassified amounts related to the Janssen Agreement from "Inventories, net" and from "Prepaid expenses and other current assets" to "Other assets", resulting in $152.7 million in long-term assets related to the Janssen Agreement on the Condensed Consolidated Balance Sheet as of December 31, 2022. The long-term asset balance within "Other Assets" related to the Janssen Agreement as of September 30, 2023 was $153.8 million. These assets include termination penalties, certain inventory related items and raw materials inventory representing materials purchased for the Janssen Agreement which Janssen has not reimbursed. The Company evaluated the net realizable value of the inventory as of September 30, 2023, concluding that because the Janssen 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 $5.0 million of non-cancelable orders as of September 30, 2023 which have not been received and Janssen has not reimbursed.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Loss per common share

Earnings Per Share [Abstract]

Loss per common share

Basic loss per common share is calculated using the treasury method by dividing net loss by the weighted average number of shares of common stock outstanding during the period. Diluted loss per common share adjusts basic loss per common share for the effects of potentially dilutive common shares and is calculated using the treasury stock method. Potentially dilutive common shares include the dilutive effect of shares issuable under our equity compensation plans, including stock options, restricted stock units and performance stock units. Diluted loss per share excludes anti-dilutive securities, which represent the number of potential common shares related to shares issuable under our equity compensation plan that were excluded from diluted loss per common share because their effect would have been antidilutive.

The following table presents the calculation of basic and diluted loss per common share:
