Exhibit 99.1

ANTARES PHARMA REPORTS FOURTH QUARTER AND FULL YEAR 2019 OPERATING AND FINANCIAL RESULTS

Record Quarterly Revenue of $37.8 Million – Earnings Per Share of $0.03

Record Annual Revenue of $123.9 Million, a 95% Increase over 2018 Annual Revenue

EWING, NJ, March 3, 2020 -- Antares Pharma, Inc. (NASDAQ: ATRS) (“the Company”) today reported operating and financial results for the fourth quarter and full year ended December 31, 2019.  The Company reported total revenue of $37.8 million for the fourth quarter of 2019 and $123.9 million for the year ended December 31, 2019.  Net income per share was $0.03 for the fourth quarter of 2019 and a net loss per share of $0.01 for the year ended December 31, 2019.

“Our evolution as a pharmaceutical technology company continued in 2019, as we delivered record revenue and the Company’s first full year of operating income. Our revenue of almost $124 million and first time annual operating income was driven by the successful launch of our proprietary product XYOSTED and Teva’s generic epipen,” said Robert F. Apple, President and Chief Executive Officer of the Company. “We believe the XYOSTED launch exceeded expectations, solidifying our commercial effectiveness, and that our operational capabilities contributed to the success of the generic epipen launch. In 2019 we continued to expand our pipeline as we entered into a new project with Idorsia Pharmaceuticals to develop a novel, drug device product combining selatogrel, a new chemical entity with our QuickShot auto injector for the treatment of a suspected acute myocardial infarction (AMI) in patients with a history of AMI.  As we look ahead to 2020, we believe our strong financial position and established commercial operations provide a foundation to help fuel continued growth of XYOSTED and progress of our pipeline.”

Fourth Quarter 2019 and Recent Highlights

Fourth Quarter and Year-to-Date Financial Results

Total revenue represents revenue generated from product sales, development activities and royalties.  Total revenue was $37.8 million for the three months ended December 31, 2019, compared to $18.8 million for the comparable period in 2018, a 101% increase.   For the year ended December 31, 2019, total revenue was $123.9 million, compared to $63.6 million for the comparable period in 2018, a 95% increase.

Product sales were a record $28.5 million for the three months ended December 31, 2019, compared to $14.2 million for the comparable period in 2018, a 100% increase.  For the year ended December 31, 2019, product sales were $92.1 million, compared to $47.9 million for the comparable period in 2018, a 92% increase.   

Sales of our proprietary products XYOSTED^® and OTREXUP^® generated revenue of $14.0 million and $39.2 million for the three and twelve months ended December 31, 2019, respectively, as compared to $5.7 million and $17.5 million for the three and twelve months ended December 31, 2018, respectively. The increase in proprietary product sales for the three and twelve months ended December 31, 2019 as compared to the three and twelve months ended December 31, 2018 was principally attributable to sales of XYOSTED^®, which was launched in late 2018.  

We sell devices, components and fully assembled and packaged product to our partners Teva, AMAG and Ferring Pharmaceuticals.  Partnered product sales were $14.5 million and $8.5 million for the three months ended December 31, 2019 and 2018, respectively, and $52.9 million and $30.3 million for the year ended December 31, 2019 and 2018, respectively. The increase in sales of partnered products for the three and twelve months ended December 31, 2019 as compared to the same period in 2018 is primarily attributable to sales of auto injector devices to Teva for use with their Epinephrine Injection USP. With the final payment received in October of 2019 related to the sale of our needle-free device to Ferring, we will no longer manufacture and supply needle free devices going forward.  

Licensing and development revenue includes license fees received from partners for the right to use our intellectual property and amounts earned in joint development arrangements with partners under which we perform development activities or develop new products on their behalf. Licensing and development revenue was $3.2 million and $7.5 million for the three and twelve month periods ended December 31, 2019, respectively, compared to $1.1 million and $6.8 million for the comparable periods in 2018, respectively. Licensing and development revenue for the three and twelve month periods was primarily from the Pfizer rescue pen and Teva pen development programs.

Royalties are recognized based on in-market sales of products sold by our partners. Royalty revenue was $6.2 million for the three months ended December 31, 2019 compared to $3.5 million for the same period in 2018, a 78% increase.  For the twelve month period ended December 31, 2019, royalty revenue was $24.2 million, compared to $8.9 million for the comparable period in 2018, a 171% increase.  The significant increases in royalty revenue for the three and twelve month periods were primarily attributable to royalties recognized from Teva on their net sales of Epinephrine Injection USP and from AMAG on their net sales of the Makena^® subcutaneous auto injector.

Operating expenses were $18.2 million for the fourth quarter of 2019 compared to $14.9 million in the comparable period of 2018.  Total operating expenses for the twelve months ended December 31, 2019 were $72.4 million as compared to $49.1 million for the comparable period in 2018.  The increase in operating expenses for the three and twelve month periods of 2019 was primarily attributable to additional sales and marketing expenses associated with the launch of XYOSTED^®.

Operating income was $5.6 million for the fourth quarter of 2019 compared to $6.8 million in the comparable period of 2018.  Total operating income for the twelve months ended December 31, 2019 was $1.0 million as compared to an operating loss of $4.1 million for the twelve months ended December 31, 2018. Net income was $4.7 million for the fourth quarter of 2019, compared to $6.1 million for the fourth quarter of 2018.  Net loss was $2.0 million for the twelve months ended December

31, 2019 as compared to $6.5 million for the twelve months ended December 31, 2018.  Net income per share was $0.03 and $0.04 for the three month periods ended December 31, 2019 and 2018, respectively, and net loss per share was $0.01 and $0.04 for the twelve month periods ended December 31, 2019 and 2018, respectively. The three and twelve month periods ended December 31, 2018 reflected a $12.5 million gain recognized from the sale of our needle free product line to Ferring Pharmaceuticals.

At December 31, 2019, cash, cash equivalents and short-term investments were $45.7 million compared to $27.9 million at December 31, 2018. During the second quarter of 2019, the Company amended the existing loan and security agreement with Hercules Capital and borrowed an additional $15.0 million upon execution of the agreement.
