(NYSE: EBS) today reported financial results for the first quarter ended March 31, 2026. “Emergent’s first quarter results demonstrate a strong and positive start to 2026, with healthy topline revenue of $156 million, above the high-end of our guidance range, and adjusted EBITDA of $36 million,” said Joe Papa, president and CEO of Emergent. “We are further strengthening our financial position in 2026 through our recently announced debt refinancing, which increases our strategic flexibility and meaningfully reduces interest expense payments. Additionally, we are pleased to have monetized our capability and capacity in our Canton facility by securing a strategic manufacturing partnership with Substipharm Biologics, which includes a manufacturing agreement and exclusive U.S. (future) distribution rights to its Japanese Encephalitis vaccine, following U.S. FDA approval. We maintained our market share position with NARCAN® Nasal Spray through our efforts across multiple distribution channels, as well as by launching a new carrying case and multipack presentations, and we continued to deliver our biodefense medical countermeasures to multiple government partners in the United States, Canada and around the world. Our mission to protect and save lives remains a prominent driving force for our entire team and we are proud to do so while executing our multi-year transformation plan and turnaround strategy to build several growing and profitable verticals over time."

The decrease was primarily attributable to lower sales of OTC NARCAN ® , driven primarily by an unfavorable price-volume mix in US sales, partially offset by increases in Canadian sales of branded NARCAN ® and the timing of the integration of KLOXXADO ® into the Company’s product portfolio. Anthrax MCM For Q1 2026, revenues from Anthrax MCM products decreased $26.3 million, or 55%, as compared with Q1 2025. The decrease was due to lower international sales of ANTHRASIL ® , mainly to the Canadian government, coupled with lower volumes of CYFENDUS ® sales to the USG, primarily due to the impact of timing. These decreases were partially offset by an increase in USG BioThrax ® sales due to timing of exercised purchase options. 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, the timing of USG purchases, the availability of governmental funding and the Company’s delivery of orders that follow. Smallpox MCM For Q1 2026, revenues from Smallpox MCM products decreased $42.2 million, or 40%, as compared with Q1 2025. The decrease was primarily driven by lower ACAM2000 ® sales, largely due to reduced international volumes and an overall decline in TEMBEXA ® sales driven by lower USG sales volume due to timing partially offset by higher international sales. These decreases were partially offset by an increase in CNJ-016 ® (VIGIV) USG sales due to timing. Fluctuations in revenues from Smallpox MCM result from the timing of the exercise of annual purchase options in the existing procurement contracts, the timing of USG purchases, the availability of governmental funding and the Company’s delivery of orders that follow. Other Products For Q1 2026, revenues from Other Product sales increased $13.7 million, or 596%, as compared with Q1 2025. The increase was primarily due to higher Canadian and other international BAT ® sales. All Other Revenues Services For Q1 2026, revenues from Services decreased $2.2 million, or 31%, as compared with Q1 2025. The decrease was primarily attributable to a decline in production at the Company’s Winnipeg facility. Contracts and Grants For Q1 2026, revenues from contracts and grants decreased $6.7 million, or 51%, as compared with Q1 2025. The decrease was primarily due to lower project spend on Ebanga™ related development work. Operating Expenses ($ in millions) Q1 2026 Q1 2025 $ Change % Change Cost of product and services sales, net $ 72.0 $ 88.5 $ (16.5 ) (19 )% Research and development (“R&D”) 10.5 15.1 (4.6 ) (30 )% Selling, general and administrative (“SG&A”) 46.6 52.4 (5.8 ) (11 )% Amortization of intangible assets 16.5 16.3 0.2 1 % Total operating expenses $ 145.6 $ 172.3 $ (26.7 ) (15 )% Cost of Product and Services Sales, Net For Q1 2026, cost of product and services sales, net decreased $16.5 million, or 19%, as compared with Q1 2025. The decrease was driven by reductions in cost of MCM Product sales of $13.4 million and cost of Services of $5.4 million, partially offset by an increase in cost of Commercial Product sales of $2.3 million. Research and Development Expenses For Q1 2026, R&D expenses decreased $4.6 million, or 30%, as compared with Q1 2025. The decrease was primarily due to lower project spend on Ebanga™ related development work, partially offset by increases in development overhead spend. Selling, General and Administrative Expenses For Q1 2026, SG&A expenses decreased $5.8 million, or 11%, as compared with Q1 2025. The decrease was primarily due to lower professional services, marketing, and administrative support expenses, primarily attributable to cost-saving initiatives implemented as part of the Company’s ongoing turnaround and transformation efforts. ADDITIONAL FINANCIAL INFORMATION (1) Capital Expenditures ($ in millions) Q1 2026 Q1 2025 % Change Capital expenditures $ 2.4 $ 3.6 (33)% Capital expenditures as a % of total revenues 2 % 2 % For Q1 2026, capital expenditures decreased largely due to reduced development activities across the Company’s facilities. REPORTABLE SEGMENT INFORMATION The Company manages the business with a focus on three operating segments: (1) a Commercial Products segment consisting of NARCAN ® Nasal Spray and KLOXXADO ® Nasal Spray; (2) a MCM Products segment consisting of Anthrax - MCM, Smallpox - MCM and Other products and (3) a services segment consisting of our Bioservices offerings (“Services”). Commercial Products and MCM Products are our two reportable segments. The Services operating segment no longer meets the quantitative thresholds of a reportable segment and did not meet the aggregation criteria set forth in Accounting Standards Codification 280, Segment Reporting, and as such is categorized within “All other revenues” along with “Contracts and Grants”. The Company evaluates the performance of these reportable segments based on revenues and segment adjusted gross margin, which is a non-GAAP financial measure. Segment revenue includes external customer sales but does not include inter-segment services. The Company does not allocate contracts and grants revenue, R&D, SG&A, amortization of intangible assets, interest and other income (expense) or taxes to its evaluation of the performance of these segments. FIRST QUARTER 2026 REPORTABLE SEGMENT RESULTS ($ in millions) Commercial Products Quarter Ended March 31, 2026 2025 $ Change % Change Revenues $ 42.9 $ 45.3 $ (2.4 ) (5 )% Cost of sales 26.8 24.5 2.3 9 % Intangible asset amortization 9.4 9.5 (0.1 ) (1 )% Gross margin * $ 6.7 $ 11.3 $ (4.6 ) (41 )% Gross margin % * 16 % 25 % Add back: Intangible asset amortization $ 9.4 $ 9.5 $ (0.1 ) (1 )% Segment adjusted gross margin ** $ 16.1 $ 20.8 $ (4.7 ) (23 )% Segment adjusted gross margin % ** 38 % 46 % * Gross margin is calculated as revenues less cost of sales and intangible asset amortization. Gross margin % is calculated as gross margin divided by revenues. ** Segment adjusted gross margin, which is a non-GAAP financial measure, for our Commercial Products segment is calculated as gross margin plus intangible asset amortization. Segment adjusted gross margin percentage, which is a non-GAAP financial measure, is calculated as segment adjusted gross margin divided by revenues. The Company’s management utilizes segment adjusted gross margin and segment adjusted gross margin percentage for purposes of evaluating our ongoing operations and for internal planning and forecasting purposes. We believe that these non-GAAP operating measures, when reviewed collectively with our GAAP financial information, provide useful supplemental information to investors in assessing our operating performance. Cost of Commercial Product sales increased $2.3 million, or 9%, to $26.8 million for the quarter ended March 31, 2026. The increase was primarily due to higher KLOXXADO ® sales due to timing of its integration into the Company’s product portfolio, and Canadian branded NARCAN ® sales. Commercial Products gross margin decreased $4.6 million, or 41%, to $6.7 million for the quarter ended March 31, 2026. Commercial Products gross margin percentage decreased 9 percentage points to 16% for the quarter ended March 31, 2026. The decrease was largely due to an unfavorable price and volume mix of OTC NARCAN ® as well as Canadian branded NARCAN ® . Commercial Products segment adjusted gross margin in the current year period excludes the impact of intangible asset amortization of $9.4 million. ($ in millions) MCM Products Quarter Ended March 31, 2026 2025 $ Change % Change Revenues $ 101.8 $ 156.6 $ (54.8 ) (35 )% Cost of sales 36.8 50.2 (13.4 ) (27 )% Intangible asset amortization 7.1 6.8 0.3 4 % Gross margin * $ 57.9 $ 99.6 $ (41.7 ) (42 )% Gross margin % * 57 % 64 % Add back: Intangible asset amortization $ 7.1 $ 6.8 $ 0.3 4 % Inventory step-up provision 0.1 1.8 (1.7 ) (94 )% Severance and restructuring benefits — (0.8 ) 0.8 100 % Stock-based compensation expense 0.5 0.3 0.2 67 % Segment adjusted gross margin** $ 65.6 $ 107.7 $ (42.1 ) (39 )% Segment adjusted gross margin %** 64 % 69 % * Gross margin is calculated as revenues less cost of sales and intangible asset amortization. Gross margin % is calculated as gross margin divided by revenues. ** Segment adjusted gross margin, which is a non-GAAP financial measure, for our MCM Products segment is calculated as gross margin plus intangible asset amortization, inventory step-up provision, severance and restructuring benefits and the portion of stock-based compensation expense that is recorded as cost of sales. Segment adjusted gross margin percentage, which is a non-GAAP financial measure, is calculated as segment adjusted gross margin divided by revenues. The Company’s management utilizes segment adjusted gross margin and segment adjusted gross margin percentage for purposes of evaluating our ongoing operations and for internal planning and forecasting purposes. In calculating these measures, we began excluding stock-based compensation that is recorded as cost of sales in the first quarter of 2026, as this reflects a non-cash expenditure that is not related to segment operating performance. As reflected in the table above, we have recast our 2025 results to also reflect this adjustment. We believe that these non-GAAP operating measures, when reviewed collectively with our GAAP financial information, provide useful supplemental information to investors in assessing our operating performance. Cost of MCM product sales decreased $13.4 million, or 27%, to $36.8 million for the quarter ended March 31, 2026. The decrease was primarily due to lower cost of sales for ANTHRASIL ® , ACAM2000 ® , CYFENDUS ® and TEMBEXA ® reflecting reduced sales volumes and the absence of significant prior-year non-recurring manufacturing related costs, including shutdown and severance expenses. These decreases were partially offset by an increase in cost of sales for CNJ-016 ® (VIGIV), BAT ® and BioThrax ® driven by greater sales volumes and increased overhead costs at the Winnipeg facility. MCM Product gross margin decreased $41.7 million, or 42%, to $57.9 million for the quarter ended March 31, 2026. MCM Product gross margin percentage decreased 7 percentage points to 57% for the quarter ended March 31, 2026. The decrease in gross margin percentage was primarily due to an unfavorable sales mix weighted more heavily toward lower margin products as well as product absorption-related variances. These impacts were partially offset by a decrease in shutdown and severance related costs compared with the prior year. MCM Product segment adjusted gross margin in the current year period excludes the impacts of intangible asset amortization of $7.1 million, the portion of stock-based compensation expense recorded as cost of sales of $0.5 million, and inventory step-up provision of $0.1 million. 2026 FINANCIAL FORECAST The Company provides the following updated financial forecast for full year 2026, reflecting management's expectations based on the most current information available.

NON-GAAP FINANCIAL MEASURES In the accompanying analysis of financial information, we sometimes use information derived from consolidated and segment financial information that may not be presented in our financial statements or prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). Certain of these financial measures are considered not in conformity with GAAP (“non-GAAP financial measures”) under the United States Securities and Exchange Commission (“SEC”) rules. Specifically, we have referred to the following non-GAAP financial measures: Adjusted Net Income Adjusted Net Income per Diluted Share Adjusted EBITDA Adjusted EBITDA Margin Adjusted Gross Margin Adjusted Gross Margin % Segment Adjusted Gross Margin Segment Adjusted Gross Margin % We define Adjusted Net Income and Adjusted Net Income per Diluted Share, which are non-GAAP financial measures, as net income and net income per diluted share, respectively, excluding the impact of non-cash amortization charges, severance and restructuring costs (benefits), inventory step-up provision, acquisition and divestiture costs, loss on assets held for sale, contingent consideration milestones, changes in fair value of financial instruments, stock-based compensation expense, other income, net and tax effects. In the first quarter of 2026 we revised our calculation of these measures to exclude the impact of stock-based compensation expense, as this is a non-cash expense that is not related to our operating performance. We use Adjusted Net Income for the purpose of calculating Adjusted Net Income per Diluted Share. Management uses Adjusted Net Income per Diluted Share to assess total Company operating performance on a consistent basis. We believe that these non-GAAP financial measures, when considered together with our GAAP financial results and GAAP financial measures, provide management and investors with an additional understanding of our business operating results, including underlying trends. We define Adjusted EBITDA, which is a non-GAAP financial measure, as net income before depreciation and amortization, income taxes, total interest expense, net, inventory step-up provision, changes in fair value of financial instruments, severance and restructuring costs (benefits), acquisition and divestiture costs, loss on assets held for sale, contingent consideration milestones, stock-based compensation expense and other income, net items. We define Adjusted EBITDA Margin, which is a non-GAAP financial measure, as Adjusted EBITDA divided by Total Revenues. In the first quarter of 2026 we revised our calculation of these measures to exclude the impact of stock-based compensation expense, as this is a non-cash expense that is not related to our operating performance. We believe that these non-GAAP financial measures, when considered together with our GAAP financial results and GAAP financial measures, provide management and investors with a more complete understanding of our operating results, including underlying trends. In addition, EBITDA is a common alternative measure of operating performance used by many of our competitors. It is used by investors, financial analysts, rating agencies and others to value and compare the financial performance of companies in our industry, although it may be defined differently by different companies. Therefore, we also believe that this non-GAAP financial measure, considered along with corresponding GAAP financial measures, provides management and investors with additional information for comparison of our operating results with the operating results of other companies. We define Adjusted Gross Margin, which is a non-GAAP financial measure, as Gross Margin, excluding the impact of intangible asset amortization, stock-based compensation expense, severance and restructuring costs (benefits) and inventory step-up provision. We define Adjusted Gross Margin %, which is a non-GAAP financial measure, as Adjusted Gross Margin as a percentage of Products and services sales, net. In the first quarter of 2026 we revised our calculation of these measures to exclude the impact of stock-based compensation expense, as this is a non-cash expense that is not related to our operating performance. We define Segment Adjusted Gross Margin, which is a non-GAAP financial measure, as a segment's Gross Margin excluding the respective impact of intangible asset amortization, restructuring costs (benefits), stock-based compensation expense and inventory step-up provision. We define Segment Adjusted Gross Margin %, which is a non-GAAP financial measure, as Segment Adjusted Gross Margin as a percentage of a segment's revenues. In the first quarter of 2026 we revised our calculation of these measures to exclude the impact of stock-based compensation expense, as this is a non-cash expense that is not related to segment operating performance. Non-GAAP financial measures are not defined in the same manner by all companies and may not be comparable with other similarly titled measures of other companies. The determination of the amounts that are excluded from these non-GAAP financial measures are a matter of management judgment and depend upon, among other factors, the nature of the underlying expense or income amounts. Non-GAAP financial measures should be considered in addition to, but not as a substitute for or superior to, the information contained in our Consolidated Statements of Operations and Consolidated Statements of Cash Flows. Reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures are included in the financial tables accompanying this press release.

GAITHERSBURG, Md., April 30, 2026 (GLOBE NEWSWIRE) -- Emergent BioSolutions Inc. (NYSE: EBS) today announced that Singapore’s Health Sciences Authority (HSA) has approved an expanded indication for ACAM2000 ® (Smallpox and Mpox (Vaccinia) Vaccine, Live) to include prevention of mpox disease in adults determined to be at high risk for mpox infection. The expanded indication in Singapore is supported by existing human safety data and data from a well-controlled animal study in which ACAM2000 ® vaccine was shown to be effective in protecting against mpox virus exposure. This regulatory milestone expands the authorized use of ACAM2000 ® in Singapore to support public health preparedness and response efforts. “The Singapore HSA approval of ACAM2000 ® for immunization against mpox in high-risk individuals demonstrates the strength and breadth of Emergent’s medical countermeasures portfolio,” said Simon Lowry, chief medical officer of Emergent. “We are committed to working with international regulatory authorities as part of our broader vision to become the leader in delivering protective and life-saving solutions to communities around the world.” ACAM2000 ® is a single-dose vaccine administered percutaneously via a bifurcated needle dipped into the vaccine solution and used to prick the skin several times in the upper arm with a droplet of the vaccine. The vaccine was first approved by the HSA in 2009 for active immunization for the prevention of smallpox disease in individuals determined to be at high risk for smallpox infection. With this expanded indication, the vaccine is now also approved for active immunization for the prevention of mpox disease in adults determined to be at high risk for mpox infection, for use during mpox outbreaks associated with severe or life-threatening disease where alternative vaccines are unavailable or contraindicated. Mpox is an infectious disease endemic to central and west Africa caused by the double-stranded DNA mpox virus. About ACAM2000 ® (Smallpox and Mpox (Vaccinia) Vaccine, Live) US FDA-Approved Indication and Important Safety Information Indication ACAM2000 ® is indicated for active immunization for the prevention of smallpox and mpox disease in individuals determined to be at high risk for smallpox and mpox infection.
