Accounting Policies [Abstract]
Basis of presentation and principles of consolidation	Basis of presentation and principles of consolidation Basis of presentation 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 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 the Company's Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC. All 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, 2022. 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, 2022, there is $238.0 million outstanding on the revolver loan and $371.3 million on the term loan that matures in October 2023, which is within one year of the date that the consolidated financial statements are issued for the quarter ended September 30, 2022. 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 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 revolver loan and term loan that are due October 2023. While the Company is in the process of and expects to replace the current credit facility before it matures, 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 the new credit facility is in place. The Company is currently working with its lenders and expects to refinance the credit facility 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 our existing credit facility when it matures or cause us to pay higher interest rates upon refinancing. As the replacement of the Company’s current debt facility is conditional upon the execution of agreements with new or existing third parties, which are considered outside of the Company’s control, until such time as they are completed, the refinancing cannot be considered to be probable to occur as of the date of this report. 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. Significant accounting policies During the nine months ended September 30, 2022, there have been no significant changes to the Company's summary of significant accounting policies contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC that have materially impacted the presentation of the Company's financial statements. During the nine months ended September 30, 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 the Government - MCM and Commercial business lines and 2) Services segment focused on CDMO. This change is further outlined in Note 14, "Segment information". 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. The Company has cash held in money market accounts (level 1) and time deposits (level 2), contingent purchase consideration (level 3) and interest rate swaps arrangements (level 2) that are measured at fair value on a recurring basis (Note 7, "Fair value measurements" and Note 8, "Derivative instruments and hedging activities"). On a non-recurring basis, the Company measures its long-lived assets as part of impairment evaluations using fair value measurements. Goodwill is allocated to the Company's reporting units, which are one level below its operating segments. The Company evaluates goodwill and other indefinite-lived intangible assets for impairment annually as of October 1 and earlier if an event or other circumstance indicates that the carrying value of the asset may not be recoverable. 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. Long-lived assets such as intangible assets and property, plant and equipment are not required to be tested for impairment annually. Instead, long-lived assets are tested for impairment whenever circumstances indicate that the carrying amount of the asset may not be recoverable, such as when there is an adverse change in the market relating to those related assets. The impairment test first requires a comparison of undiscounted future cash flows to the carrying value of the asset. Determining the need for a detailed impairment analysis requires the exercise of judgment about several business factors, including the timing of expected future cash flows and assumptions about the economic environment. As of September 30, 2022 and December 31, 2021, the Company had no other significant assets or liabilities that were measured at fair value. Recently issued accounting standards From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (FASB) that the Company adopts as of the pronouncement's specified effective date. Unless otherwise discussed below, the Company does not believe that the adoption of recently issued standards have or may have a material impact on the consolidated financial statements or disclosures. Recently Adopted ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting In March 2020, the FASB issued Topic 848, which was further amended in January 2021. Topic 848 provides relief for impacted areas as it relates to impending reference rate reform. It contains optional expedients and exceptions to debt arrangements, contracts, hedging relationships, and other areas or transactions that are impacted by reference rate reform. This guidance is effective upon issuance for all entities and elections of certain optional expedients are required to apply the provisions of the guidance. As of September 30, 2022, the Company adopted this ASU with no material impact to our consolidated financial statements.
