2016 FINANCIAL PERFORMANCE

(I) Quarter Ended March 31, 2016 (unaudited)

Product Sales

For Q1 2016, product sales were $71.7 million, an increase of 292% as compared to 2015. This increase was driven by an increase in BioThrax sales due to the Company's decision to suspend shipments to the CDC in the first quarter of 2015 following the discovery of foreign particles in a limited number of vials in two manufactured lots of BioThrax in January 2015. As a result, there were no revenues for BioThrax product sales to the CDC for the three months ended March 31, 2015. The decrease in Other Biodefense revenues is due to a one-time milestone payment of $7 million recognized in 2015 for FDA approval of Anthrasil.

Contract Manufacturing

For Q1 2016, revenue from the Company's contract manufacturing operations was $7.6 million, a decrease of 38% as compared to 2015. The decrease was primarily due to the timing of fill/finish services to third parties and revenue from the production of an Ebola vaccine in 2015.

Contracts, Grants and Collaborations

For Q1 2016, contracts, grants and collaborations revenue was $31.7 million, a decrease of 4% as compared to 2015.

Cost of Product Sales and Contract Manufacturing

For Q1 2016, cost of product sales and contract manufacturing was $28.5 million, an increase of 52% as compared to 2015. The increase was primarily attributable to increased sales of BioThrax to the CDC.

Research and Development

For Q1 2016, gross research and development (R&D) expenses were $34.2 million, a decrease of 12% as compared to 2015. The decrease primarily reflects lower contract service costs associated with product candidates in the Biodefense business segment and product candidates and technology platform development activities associated with the Aptevo business segment.

For Q1 2016, net R&D expenses were $2.4 million, a decrease of 56% as compared to 2015. Net R&D expenses, which are more representative of the Company's actual out-of-pocket investment in product development, are calculated as gross research and development expenses less contracts, grants and collaboration revenues.

Selling, General and Administrative

For Q1 2016, selling, general and administrative expenses were $39.8 million, an increase of 15% as compared to 2015. The increase was primarily attributable to costs associated with the Aptevo spin-off and professional services to support the Company's strategic growth initiatives.

Net Income

For Q1 2016, GAAP net income was $4.0 million versus a net loss of $21.5 million in 2015. For Q1 2016, GAAP net income per diluted share is computed using the if-converted method. This method requires GAAP net income to be adjusted to reflect the add back of interest expense and amortization of debt issuance cost, both net of tax, associated with the Company's 2.875% Convertible Senior Notes due 2021. As a result, GAAP net income per diluted share for Q1 2016 is increased in the amount of $0.9 million, from $4.0 million to $4.9 million. With 48.4 million diluted shares outstanding, GAAP net income per diluted share for Q1 2016 was $0.10.

RECONCILIATION OF GAAP NET INCOME/(LOSS) TO ADJUSTED NET INCOME/(LOSS), EBITDA AND ADJUSTED EBITDA

This press release contains three financial measures (Adjusted Net Income/(Loss), EBITDA (Earnings Before Interest, Taxes, Depreciation and Amortization), and adjusted EBITDA) that are considered "non-GAAP" financial measures under applicable Securities & Exchange Commission rules and regulations. These non-GAAP financial measures 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 these non-GAAP measures may differ from similarly titled measures used by others. Adjusted Net Income/(Loss) 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. EBITDA reflects net income excluding the impact of depreciation, amortization, interest expense and provision for income taxes. Adjusted EBITDA also excludes specified items that can be highly variable and the non-cash impact of certain purchase accounting adjustments. The Company views these non-GAAP financial measures 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. These non-GAAP financial measures reflect 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 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. 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.
