• Advances Biosciences Division toward profitability through significant commercial product and service revenue
• Broadens manufacturing capabilities with revenue generating fill/finish business
• Expected to be accretive in 2014, exclusive of transaction-related costs

ROCKVILLE, MD; USA I December 11, 2013 I Emergent BioSolutions Inc. (NYSE: EBS) announced today that it has entered into a definitive agreement with Cangene Corporation (TSX: CNJ) under which Emergent will acquire all of the outstanding common shares of Cangene in an all-cash transaction valued at $3.24 per share on a fully diluted basis for an aggregate purchase price of $222 million. The transaction is consistent with Emergent’s growth plan in that it diversifies the company’s revenue mix, adds commercial product sales and contributes to earnings growth. The transaction is expected to be accretive in 2014, exclusive of transaction-related costs.

The Boards of Directors of both companies have approved the transaction. Agreements are in place with shareholders who collectively control, directly or indirectly, approximately 61% of the outstanding common shares of Cangene, under which they have agreed to irrevocably support and vote in favor of the transaction. The companies expect to complete the transaction in the first calendar quarter of 2014.

“The acquisition of Cangene is consistent with our stated growth plan to acquire revenue generating products that leverage our core capabilities,” said Daniel J. Abdun-Nabi, president and chief executive officer of Emergent BioSolutions. “The addition of Cangene is expected to accelerate our growth driven by a substantially expanded biodefense franchise, a portfolio of approved specialty therapeutics sold through an established commercial infrastructure, and fill/finish manufacturing capabilities with growing contract revenues. The combined company presents a clearly attractive financial profile with pro forma total revenues of over $430 million and pre-tax operating income of approximately $55 million. This acquisition represents an important step in advancing Emergent’s leadership in specialty pharmaceuticals and positions us to drive significant growth in shareholder value.”

Cangene Corporation is a biopharmaceutical company focused on the development and commercialization of specialty therapeutics, primarily targeting biodefense applications as well as infectious disease, hematology and transplantation. Cangene has three specialty products that are included in the U.S. Strategic National Stockpile: BAT^® (Botulism Antitoxin (Equine) Heptavalent), VIGIV^® (Vaccinia Immune Globulin Intravenous (Human)), and AIGIV (Anthrax Immune Globulin Intravenous). Cangene also has four approved commercial specialty products: WinRho^® SDF (Rho(D) Immune Globulin Intravenous (Human)), HepaGam B^® (Hepatitis B Immune Globulin (Human) Injection), VARIZIG^® (Varicella Zoster Immune Globulin (Human)), and episil^®. Cangene maintains manufacturing and plasma collection facilities in Winnipeg, Manitoba, contract manufacturing facilities in Baltimore, Maryland, and a sales and marketing office in Philadelphia, Pennsylvania.

“This transaction represents an exciting and very promising opportunity for Cangene and delivers significant value to our shareholders,” stated John Sedor, president and chief executive officer of Cangene Corporation. “Cangene has a history of success in medical countermeasures while building a growing, profitable product portfolio supported by a strong, focused commercial platform and an established contract manufacturing operation. Our diversified business across biodefense, specialty pharmaceuticals and contract manufacturing is strategically consistent with Emergent’s infrastructure and vision for the future. We are confident the Emergent team believes in what we do, in our products, in our people and in our potential. We look forward to building a highly successful future together.”

Financing

In connection with the transaction, Emergent has secured committed debt financing from Bank of America Merrill Lynch along with PNC Bank and J.P. Morgan Chase Bank, N.A., totaling $225 million, which, when combined with existing cash reserves, will be used to finance the acquisition and repay existing indebtedness. The company also anticipates there will be approximately $35 million of cash from Cangene at closing.

Transaction Structure and Approvals

The transaction is structured as a Canadian court-approved plan of arrangement. Completion of the transaction is subject to approval by 66 2/3% of the votes cast by Cangene shareholders, approval by the Ontario Superior Court of Justice, certain regulatory approvals and customary closing conditions. Agreements are in place with shareholders who collectively control directly or indirectly approximately 61% of the outstanding common shares of Cangene, under which they have agreed to irrevocably support and vote in favor of the transaction.

Guidance

Taking into account the expected closing date of Q1 2014, the company is reaffirming its full year 2013 GAAP guidance for total revenues of $300 to $310 million and net income of $25 to $30 million. Excluding approximately $7 million in estimated transaction-related and other costs incurred in the current year, the company is providing a forecast for 2013 non-GAAP adjusted net income of $30 to $35 million (see “Non-GAAP Financial Measures” for a definition of terms and a reconciliation of Non-GAAP adjusted net income to GAAP net income).

The company expects that the transaction will be accretive for 2014 and beyond, assuming a Q1 2014 close. The company anticipates:

• revenue contribution of $90 to $100 million for the partial year period of 2014 with a compound annual growth rate of 4% to 6% over the following three year period (2015-2018); and
• pre-tax operating margin contribution of 4% to 6%, exclusive of transaction-related costs, for the partial year period of 2014, improving to a target of 15% over the following three year period (2015-2018).

Non-GAAP Financial Measures

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. The company views this non-GAAP financial measure as a means to facilitate management’s financial and operational decision-making, including evaluation of Emergent’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 Emergent’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 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 amortization of acquired intangible and tangible assets, and transaction costs;
• Expenses associated with any potential restructuring activities, including but not limited to, asset impairments, accelerated depreciation, severance costs and lease abandonment charges; and
• Other one-time or 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. A reconciliation of the non-GAAP financial measure to the most directly comparable GAAP financial measure is included in the following table.

Advisors

For Emergent, Bank of America Merrill Lynch is acting as financial advisor and DLA Piper and McCarthy Tètrault LLP are acting as legal advisors. For Cangene, Credit Suisse is acting as financial advisor, Raymond James Ltd. provided a fairness opinion and Miller Thomson LLP and Baker & Hostetler LLP are acting as legal advisors.

IMPORTANT SAFETY INFORMATION

Important Information about BAT^® — Botulism Antitoxin (Equine), Heptavalent (A, B, C, D, E, F, G) (See full prescribing information)

The effectiveness of BAT is based solely on efficacy studies conducted in animal models of botulism.

Animal reproduction studies have not been conducted with BAT. It is not known whether BAT can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. BAT should only be given to pregnant women if the benefits outweigh the risks.

The effectiveness of BAT has not been established in pediatric patients. Limited pediatric safety data are available. Dosing in pediatric patients is based on Salisbury Rule.

Important Information about VIGIV^® — CNJ-016, Vaccinia Immune Globulin Intravenous^TM (Human), (See full prescribing information for complete boxed warning)

WARNING: INTERACTIONS WITH GLUCOSE MONITORING SYSTEMS

Blood glucose measurement in patients receiving Vaccinia Immune Globulin Intravenous (Human) (VIGIV) must be done with a glucose-specific method (monitor and test strips) to avoid interference by maltose contained in VIGIV. Maltose in IGIV products may give falsely high blood glucose levels in certain types of blood glucose testing systems (for example those based on the GDH-PQQ or glucose-dye-oxidoreductase methods) resulting in inappropriate administration of insulin and life-threatening hypoglycemia. Cases of true hypoglycemia may go untreated if the hypoglycemic state is masked by falsely elevated glucose readings.

Carefully review the product information of the blood glucose testing system, including that of the test strips, to determine if the system is appropriate for use with maltose-containing parenteral products [see WARNINGS AND PRECAUTIONS (5.3)].

VIGIV is not indicated for isolated vaccinia keratitis or postvaccinial encephalitis.

Animal reproduction studies have not been conducted with VIGIV; therefore, it is not known whether VIGIV can cause fetal harm when administered to a pregnant woman or whether it can affect reproduction capacity. The risk/benefit of VIGIV administration should be assessed for each individual case.

Use VIGIV with caution in patients with pre-existing renal insufficiency and in patients at increased risk of developing renal insufficiency.

Important Information about WinRho^® SDF [Rh_o(D) Immune Globulin Intravenous (Human)] (See full prescribing information for complete boxed warning.)

WARNING: INTRAVASCULAR HEMOLYSIS (IVH)

This warning does not apply to Rh_o(D)-negative patients treated for the suppression of Rh isoimmunization.

Intravascular hemolysis (IVH) leading to death has been reported in patients treated with WinRho^® SDF for immune thrombocytopenic purpura (ITP).

IVH can lead to clinically compromising anemia and multi-system organ failure including acute respiratory distress syndrome (ARDS).

Serious complications including severe anemia, acute renal insufficiency, renal failure and disseminated intravascular coagulation (DIC) have also been reported.

Closely monitor patients treated with WinRho^® SDF for ITP in a healthcare setting for at least eight hours after administration. A dipstick urinalysis to monitor for hematuria and hemoglobinuria is to be performed at baseline and then after administration at 2 hours, 4 hours and prior to the end of the monitoring period. Alert patients and monitor the signs and symptoms of IVH including back pain, shaking chills, fever, and discolored urine or hemoglobinuria. Absence of these signs and/or symptoms of IVH within eight hours do not indicate IVH cannot occur subsequently. If signs and/or symptoms of IVH are present or suspected after WinRho^® SDF administration, post-treatment laboratory tests should be performed including plasma hemoglobin, haptoglobin, LDH, and plasma bilirubin (direct and indirect).

The safety and efficacy of WinRho^® SDF have not been evaluated in clinical trials for patients with non-ITP causes of thrombocytopenia or in previously splenectomized patients or in patients who are Rh_o(D)-negative.

WinRho^® SDF is not indicated for use as immunoglobulin replacement therapy for immune globulin deficiency syndromes.

Animal reproduction studies have not been conducted with WinRho^® SDF. It is also not known whether WinRho^® SDF can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. WinRho^® SDF should be given to a pregnant woman only if clearly needed.

Important Information about HepaGam B^® [Hepatitis B Immune Globulin Intravenous (Human)] (See full prescribing information)

Animal reproduction studies have not been conducted with HepaGam B. It is also not known whether HepaGam B can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. HepaGam B should be given to a pregnant woman only if clearly indicated.

It is not known whether HepaGam B is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when HepaGam B is administered to a nursing mother.

Important Information about VARIZIG^® [Varicella Zoster Immune Globulin (Human)] (See full prescribing information)

VARIZIG is indicated for post-exposure prophylaxis of varicella in high risk individuals. High risk groups include: immunocompromised children and adults, newborns of mothers with varicella shortly before or after delivery, premature infants, neonates and infants less than one year of age, adults without evidence of immunity, and pregnant women.

Administer VARIZIG as soon as possible following varicella zoster virus (VZV) exposure, ideally within 96 hours for greatest effectiveness. There is no convincing evidence that VARIZIG reduces the incidence of chickenpox infection after exposure to VZV. There is no convincing evidence that established infections with VZV can be modified by VARIZIG administration. There is no indication for the prophylactic use of VARIZIG in immunodeficient children or adults when there is a past history of varicella, unless the patient is undergoing bone marrow transplantation.

Animal reproduction studies have not been conducted with VARIZIG. It also is not known whether VARIZIG can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. VARIZIG should be given to a pregnant woman only if clearly needed.

It is not known whether VARIZIG is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when VARIZIG is administered to a nursing mother.
