2015 Third Quarter Financial Results

As of September 30, 2015, cash and cash equivalents and investment securities available-for-sale totaled $302.4 million compared with $141.6 million at December 31, 2014.

Research and development expenses were $7.2 million for the third quarter of 2015 and $21.8 million for the nine months ended September 30, 2015, compared to $7.2 million and $19.1 million for the comparable periods in 2014. The increase in research and development expenses was primarily related to the further clinical development of ETC-1002.

General and administrative expenses were $5.7 million for the third quarter of 2015 and $15.0 million for the nine months ended September 30, 2015, compared to $2.5 million and $7.7 million for the comparable periods in 2014. The increase in general and administrative expenses was primarily attributable to costs to support public company operations, increases in headcount, which includes increased stock-based compensation expense, and other costs to support Esperion's growth.

Esperion had a net loss of $12.8 million for the third quarter of 2015 and $36.7 million for the nine months ended September 30, 2015, compared to $9.8 million and $26.9 million for the comparable periods in 2014.

The Company estimates that current cash resources are sufficient to fund the Company through at least the end of 2018 and the potential approval of ETC-1002.

Esperion's Commitment to Cardiometabolic Disease

Esperion is committed to improving the lives of patients with hypercholesterolemia by developing therapies to lower LDL-C. Esperion scientists discovered ETC-1002 and the LDL-C lowering therapy is in late stage development. Esperion plans to develop both ETC-1002 and a fixed dose combination of ETC-1002 and ezetimibe with a particular focus on patients with hypercholesterolemia who are considered intolerant of statin therapy. It is estimated that approximately 10% of patients who are prescribed statins, 3.5 million patients in the U.S., are considered statin intolerant.
