2015 Second Quarter Financial Results

As of June 30, 2015, cash and cash equivalents and investment securities available-for-sale totaled $314.3 million compared with $141.6 million at December 31, 2014.

Research and development expenses were $7.2 million for the second quarter of 2015 and $14.6 million for the six months ended June 30, 2015, compared to $6.5 million and $11.9 million for the comparable periods in 2014. The increase in research and development expenses was largely driven by the further clinical development of ETC-1002.

General and administrative expenses were $5.3 million for the second quarter of 2015 and $9.3 million for the six months ended June 30, 2015, compared to $2.7 million and $5.2 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 $12.4 million for the second quarter of 2015 and $23.9 million for the six months ended June 30, 2015, compared to $9.2 million and $17.1 million for the comparable periods in 2014.

Esperion had approximately 22.5 million shares of common stock outstanding, with an additional 2.6 million shares issuable upon exercise of stock options and warrants, and $5.0 million of debt outstanding as of June 30, 2015.

2015 Financial Outlook

Esperion expects that the net cash used to fund operating activities in 2015 will be approximately $42 million and that its cash and cash equivalents and investment securities available-for-sale will total approximately $290 million at December 31, 2015. The Company estimates that current cash resources are sufficient to fund the Company through 2018 and the expected approval of ETC-1002.

About Esperion Therapeutics

Esperion Therapeutics, Inc. is an emerging pharmaceutical company focused on developing and commercializing first-in-class, oral, LDL-cholesterol lowering therapies for the treatment of patients with hypercholesterolemia and other cardiometabolic risk markers. ETC-1002 (bempedoic acid), the Company's lead product candidate, is an inhibitor of ATP Citrate Lyase, a well-characterized enzyme on the cholesterol biosynthesis pathway; the same pathway that includes HMG-CoA reductase, the enzyme target of statins. ETC-1002 and statins have the same mechanism of action; inhibiting cholesterol biosynthesis, decreasing intracellular cholesterol, up-regulating LDL-receptors, and causing increased LDL-cholesterol clearance and reduced plasma levels of LDL-cholesterol. ETC-1002 is being developed for patients with hyperlipidemia and mixed dyslipidemia. For more information, please visit www.esperion.com and follow us on Twitter at https://twitter.com/EsperionInc.
