Q1 2013 Key Financial Results

Product Sales

For Q1 2013, product sales were $30.4 million, a decrease of $4.0 million from $34.4 million for Q1 2012. This decrease was primarily due to a 14 percent decrease in the number of BioThrax doses delivered.

Contracts and Grants Revenues

For Q1 2013, contracts and grants revenues were $12.7 million, a decrease of $3.2 million from $16.0 million for Q1 2012. The decrease was primarily due to decreased revenues from the company's agreements with Abbott and Pfizer, which were terminated in 2012, and, to a lesser extent, decreased activity and associated revenue from the company's development contracts with BARDA and NIAID.

Cost of Product Sales

For Q1 2013, cost of product sales was $5.7 million, a decrease of $1.8 million from $7.5 million for Q1 2012. This decrease was substantially attributable to the decrease in the number of BioThrax doses delivered and the decrease in the average cost per dose.

Research and Development

For Q1 2013, research and development expenses were $30.7 million, an increase of $4.5 million from $26.2 million for Q1 2012. This increase primarily reflects higher contract service costs for product candidates and technology platform development activities within the Biosciences segment. Net of development contracts and grants revenue along with the net loss attributable to noncontrolling interests, research and development expenses were $17.2 million for Q1 2013.

Selling, General and Administrative

For Q1 2013, selling, general and administrative expenses were $20.0 million, relatively flat from $19.5 million for Q1 2012. This increase is primarily due to costs related to the elimination of the company's UK research and development operations, substantially offset by decreased spending related to professional services.

Financial Condition and Liquidity

Cash and cash equivalents at March 31, 2013 was $130.2 million compared to $141.7 million at December 31, 2012. Additionally, at March 31, 2013, the accounts receivable balance was $63.0 million and consisted primarily of unpaid amounts due from the US government under our procurement and development contracts.
