Exhibit 99.1

ANTARES PHARMA REPORTS FIRST QUARTER 2017 OPERATING AND FINANCIAL RESULTS

Multiple Drug Device Combination Products Pending FDA Approval

EWING, NJ, May 9, 2017 -- Antares Pharma, Inc. (NASDAQ: ATRS) today reported operating and financial results for the first quarter ended March 31, 2017.  The Company reported revenue of $12.0 million and a net loss per share of $0.03 for the period ended March 31, 2017.

“We are pleased with the continued growth in OTREXUP and Sumatriptan Injection, both products developed and supplied by Antares for commercial sale.  With the potential for a late 2017 approval of QuickShot testosterone, we will leverage and look to expand our existing commercial organization and infrastructure to support the launch of QST into a large market opportunity which we believe may benefit from a new treatment option,” said Robert F. Apple, President and Chief Executive Officer of the Company.  “The Company’s first quarter results reflect a continued focus on growing product revenue, producing prelaunch quantities of commercial devices and controlling operating expenses with appropriate reinvestment in our future while we await potential FDA approval of four partnered drug device combination products as well as our own QST product.”

First Quarter 2017 and Recent Highlights

First Quarter Financial Results

Revenue was $12.0 million for the three months ended March 31, 2017, compared to $12.3 million for the comparable period in 2016. 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 $10.0 million for the three months ended March 31, 2017, compared to

$10.8 million for the comparable period in 2016.  The decrease in product sales was primarily driven by a reduction in sales of pre-launch quantities of auto injector devices for use with Teva’s generic epinephrine product, partially offset by increased sales of Sumatriptan Injection USP and OTREXUP^®. For the three months ended March 31, 2017, we recognized a one-time increase of $1.3 million in OTREXUP^® product revenue for amounts that were previously deferred in accordance with generally accepted accounting principles. In the first quarter of 2017, we began recognizing revenue, net of estimated returns, upon delivery to distributors.

Development revenue was $1.6 million for the three months ended March 31, 2017, compared to $1.1 million for the comparable period in 2016. The increase in development revenue was primarily a result of increases in development activities with Teva for the exenatide and teriparatide pen injector products and with AMAG for the Makena^® auto injector product, offset by a reduction in revenue for development activities with Teva in connection with the epinephrine auto injector.  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.

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, 2017 and 2016, respectively.    

Gross profit increased in the first quarter of 2017 to $5.8 million compared to $5.5 million in the same period in 2016. The increase was primarily attributable to the recognition of previously deferred revenue for OTREXUP^® sales, and sales of Sumatriptan Injection USP, offset by a reduction in epinephrine auto injector device sales.

Operating expenses were approximately $10.6 million for the first quarter of 2017 compared to $13.3 million in the comparable period of 2016.  The decrease in operating expenses in the first quarter of 2017 was primarily due to a reduction in external clinical and development costs related to QST and a decrease in personnel costs in connection with the departure of the former CEO in 2016.

Net loss was $4.7 million for the first quarter of 2017, compared to $7.7 million in the comparable period in 2016.  Net loss per share was $0.03 for the quarter ended March 31, 2017 and $0.05 for the comparable period in 2016.

At March 31, 2017, cash and cash equivalents totalled $23.7 million compared to $27.7 million at December 31, 2016.
