GAITHERSBURG, Md., April 22, 2015 (GLOBE NEWSWIRE) -- Emergent BioSolutions Inc. (NYSE:EBS) announced today that it has resumed full manufacturing operations of BioThrax^® (Anthrax Vaccine Adsorbed) after completing its internal manufacturing investigation of foreign particles discovered in a limited number of vials in two manufactured BioThrax lots. Following a comprehensive assessment, the company has identified a supplier component as the most probable root cause. As a result, the company is implementing certain targeted corrective and preventive actions in the operations of its suppliers and contract manufacturers, as well as its own operations. The investigation concluded that there was no impact to any BioThrax in distribution or to any of the company's other products or manufacturing operations, including the company's Building 55 operations and plans for licensure.

With the conclusion of its investigation, the company is re-affirming its financial outlook for full-year 2015, previously issued on January 11, 2015, and issuing preliminary results for the first quarter of 2015, both of which include the full impact of all decisions on BioThrax lot disposition.

2015 Financial Outlook

Full Year 2015

For the full year of 2015, the company re-affirms its previous forecast of total revenues of $510 to $540 million, driven by growth in BioThrax sales which are anticipated to be between $270 to $285 million, continued domestic and international sales of the other Biodefense division products, incremental growth in product sales and services revenues from the Biosciences division and continued robust development funding through contracts, grants and collaborations revenues. The company also forecasts full year 2015 GAAP net income of $50 to $60 million and adjusted net income of $60 to $70 million (see "Reconciliation of GAAP to Adjusted Net Income" for a definition of terms and a reconciliation table). The company's outlook for 2015 does not include any estimates for potential new corporate development or other M&A transactions.

Q1 2015

For the first quarter of 2015, the company expects total revenues of $62-$64 million and a net loss of $21-$23 million.

Reconciliation of GAAP to Adjusted Net Income

This press release contains a financial measure, adjusted net income, which is considered a "non-GAAP" financial measure under applicable Securities & Exchange Commission rules and regulations. This non-GAAP financial measure should be considered supplemental to and not a substitute for financial information prepared in accordance with generally accepted accounting principles. The company's definition of this non-GAAP measure may differ from similarly titled measures used by others. The non-GAAP financial measure used in this press release adjusts for specified items that can be highly variable or difficult to predict, or reflect the non-cash impact of charges resulting from purchase accounting. The company views this non-GAAP financial measure as a means to facilitate management's financial and operational decision-making, including evaluation of the company's historical operating results and comparison to competitors' operating results. This non-GAAP financial measure reflects an additional way of viewing aspects of the company's operations that, when viewed with GAAP results and the reconciliations to the corresponding GAAP financial measure, may provide a more complete understanding of factors and trends affecting the company's business.

The determination of the amounts that are excluded from this non-GAAP financial measure is a matter of management judgment and depends upon, among other factors, the nature of the underlying expense or income amounts. The company is likely to exclude the following items from its non-GAAP adjusted net income (loss) in the future, the effect of which is uncertain but may be significant in amount:

• Expenses related to completed and future acquisitions of other businesses, including transaction costs and integration costs;
• Amortization of intangible assets;
• Non-cash charges related to the impairment of intangible or tangible assets;
• Expenses associated with restructuring activities, including but not limited to, accelerated depreciation, severance costs and lease abandonment charges; and
• Other non-recurring charges.

Because non-GAAP financial measures exclude the effect of items that will increase or decrease the company's reported results of operations, management strongly encourages investors to review the company's consolidated financial statements and publicly filed reports in their entirety.

The following table provides a reconciliation of GAAP to Adjusted net income for its 2015 financial outlook.
