ANTARES PHARMA REPORTS FIRST QUARTER 2016 OPERATING AND FINANCIAL RESULTS

Total Revenues of $12.3 million increased 48% Over Q1 2015

EWING, NJ, May 9, 2016 -- Antares Pharma, Inc. (NASDAQ: ATRS) today reported operating and financial results for the first quarter ended March 31, 2016.  The Company reported revenue of $12.3 million compared to $8.3 million for the comparable period in 2015, and net loss per share of $0.05 for both periods.  

“The Company reported another solid quarter of top line growth, with the primary driver of that growth coming once again from an increase in product revenue.” said Robert F. Apple, President and Chief Executive Officer of the Company.   “Antares also reported significant progress on commercial and pipeline projects which included the approval of three additional interim dosage strengths for OTREXUP, completion of the QST-13-003 52 week phase 3 study in testosterone deficient men and the acceptance by the U.S. Food and Drug Administration (FDA) of an abbreviated new drug application (ANDA) filed by our partner Teva for teriparatide, a generic form of Forteo.  The teriparatide filing represents the fourth ANDA for which Antares is the device developer and we believe the third potential generic product with a first to file status using one of our devices.  Finally, we continue to prepare for the mid-year 2016 launch of generic sumatriptan with our distribution partner Teva.”  

First Quarter 2016 and Recent Highlights

First Quarter Financial Results

Total revenue was $12.3 million for the three months ended March 31, 2016, compared to $8.3 million for the comparable period in 2015, representing growth in total revenue of 48%. See Table 1 attached for further details on revenues.  

Product sales represent sales of our proprietary products and devices or device components to our partners.  Product sales were $10.8 million for the three months ended March 31, 2016, compared to $4.6 million for the comparable period in 2015.  The increase in product sales was primarily driven by the sale of $6 million in pre-launch quantities of the epinephrine auto injector to Teva and by increased sales of OTREXUP™.   The Company expects to complete shipment of pre-launch epinephrine auto injector devices in the second quarter of 2016.

Development revenues represent amounts earned under arrangements with partners in which we develop new products on their behalf.  Frequently, we receive payments from our partners that are initially deferred and recognized as revenue over a development period or upon completion of defined deliverables.  Development revenue was $1.1 million for the three months ended March 31, 2016, compared to $2.4 million for the comparable period in 2015. The decrease in development revenue is related to the completion of certain deliverables and development activities for the epinephrine auto injector, which accounted for substantially all of the development revenue in the first quarter of 2015.  The decrease was partially offset by additional development activities for the AMAG auto injector in 2016.

Licensing revenues represent the amounts recognized from up-front or milestone payments received from partners that are initially deferred and recognized over the life of our agreements.  Licensing revenue was $51 thousand for the three months ended March 31, 2016, compared to $0.9 million for the comparable period in 2015.  The decrease in licensing revenue is related to a promotion and license agreement with LEO Pharma, Inc., which was terminated on June 23, 2015.

Royalty revenue is recognized primarily from the in-market sales of products sold by our partners.  Royalty revenue was $0.3 million for the three months ended March 31, 2016, compared to $0.5 million for the comparable period in 2015.    

Total gross profit increased in the first quarter of 2016 to $5.5 million compared to $4.7 million in the same period in 2015. The increase was primarily driven by sales of pre-launch quantities of the epinephrine auto injector to Teva and an increase in OTREXUP™sales.

Total operating expenses were approximately $13.3 million for the first quarter of 2016 compared to $11.4 million in the comparable period of 2015.  The increase in operating expenses in the first quarter of 2016 was primarily driven by external expenses incurred in connection with the development of QuickShot testosterone and increased personnel costs.

Net loss was approximately $7.7 million for the first quarter of 2016, compared to $6.8 million in the comparable period in 2015.  Net loss per share was $0.05 for the quarters ended March 31, 2016 and 2015.

At March 31, 2016, cash and investments totalled approximately $42.1 million compared to approximately $47.9 million at December 31, 2015.
