ANNAPOLIS, Md., March 14, 2017 /PRNewswire/ -- PharmAthene, Inc. (NYSE MKT: PIP), a biodefense company developing medical countermeasures against anthrax, today reported its financial and operational results for the year ended December 31, 2016.

Fourth quarter and subsequent operational highlights include:

• On November 16, PharmAthene received a final payment from SIGA Technologies, Inc. which fully satisfied the judgment owed to PharmAthene. In total, the Company received payments of approximately $217.1 million (including interest) from SIGA.
• On November 17, PharmAthene declared a special one-time cash dividend of $2.91 per share of common stock, that was paid on February 3, 2017. The special dividend, totaling an aggregate payment of approximately $200.3 million, represented approximately 98% of the after tax net cash proceeds received from SIGA.
• On January 18, 2017, PharmAthene entered into a merger agreement with Altimmune, Inc. in an all-stock transaction. Upon completion of the merger, the former PharmAthene security holders will own approximately 41.8% of the outstanding equity securities of the combined company. The combined company, which will operate as a public company under the name Altimmune, Inc., is expected to trade on the NYSE MKT under the ticker symbol "ALT."

For the year ended December 31, 2016, PharmAthene recognized revenue of $5.2 million. Of such amount, $4.4 million was derived from an existing contract with the National Institutes of Allergy and Infectious Diseases for the development of a next generation lyophilized anthrax vaccine, SparVax-L, intended to be stored at room temperature and to provide extended shelf life.  The additional $0.8 million was the result of an audit by the Biomedical Advanced Research and Development Agency on a closed contract.

Research and development expenses for 2016 of $4.8 million were incurred primarily to advance the Company's next generation anthrax vaccine programs. General and administrative expenses for 2016 were $11.5 million compared to $6.2 million in 2015. The increase is primarily due to an increase in stock compensation and other expenses related to the proposal and protest submitted to and filed with the Department of Health and Human Services in response to its request for a next generation anthrax vaccine, as well as costs associated with merger activities, offset by a decrease in SIGA-related legal expenses.

Other income for the year ended December 31, 2016 primarily consists of payments of approximately $217.1 million received from SIGA pursuant to a judgment stemming from a lawsuit filed by PharmAthene in December 2006. The complaint PharmAthene filed against SIGA alleged, among other things, that PharmAthene has the right to license exclusively the development and marketing rights for SIGA's drug candidate, Tecovirimat, also known as ST-246.

For the year ended December 31, 2016, PharmAthene's reported net income of $193.9 million, or $2.95 per diluted share, compared to a net loss of $3.4 million, or $0.05 per diluted share, for the prior year. Cash and cash equivalents were $154.0 million and short-term investments were $66.8 million in 2016. In 2015, cash and cash equivalents were $15.6 million. The increase in cash, cash equivalents and short-term investments from 2015 were due to the payments the Company received from SIGA.
