AEGERION PHARMACEUTICALS ANNOUNCES

THIRD QUARTER 2012 FINANCIAL RESULTS

Cambridge, MA, November 7, 2012 - Aegerion Pharmaceuticals, Inc. (NASDAQ: AEGR), an emerging biopharmaceutical company focused on the development and commercialization of novel therapeutics to treat debilitating and often fatal rare diseases, announced its financial results and business highlights for the third quarter and nine months ended September 30, 2012.

As previously announced, the U.S. Food and Drug Administration (FDA) held a meeting of the Endocrinologic and Metabolic Drugs Advisory Committee (EMDAC) on October 17, 2012, to review Aegerion’s New Drug Application (NDA) requesting approval to market lomitapide as an adjunct to a low-fat diet and other lipid-lowering therapies, with or without apheresis, to reduce LDL-C, total cholesterol, apolipoprotein B, and triglycerides in adults with homozygous familial hypercholesterolemia (HoFH). The EMDAC determined by a vote of 13 to 2 that Aegerion has presented sufficient safety and efficacy data to support marketing of lomitapide for this indication. The FDA is not bound by EMDAC’s recommendation, but will consider the committee’s recommendation as the agency completes its review of the lomitapide NDA.

“We have made great progress in advancing the global lomitapide development program,” said Marc D. Beer, Chief Executive Officer. “In October, we achieved a positive recommendation for approval of lomitapide by FDA’s Advisory Committee. Last week, the Lancet published the full 78 week data from Aegerion’s pivotal Phase III study of lomitapide. Finally, we continue to execute on our pre-launch initiatives, and to build our commercial resources in anticipation of potential FDA approval.”

Financial Results

For the third quarter ended September 30, 2012, net loss was $14.9 million, or $0.59 per share, compared with a net loss of $10.1 million, or $0.48 per share, for the same period in 2011. For the nine months ended September 30, 2012, net loss was $40.5 million, or $1.76 per share, compared with a net loss of $25.6 million, or $1.36 per share, for the same period in 2011.

Research and development expenses were $6.5 million for the quarter ended September 30, 2012, compared to $7.3 million for the same period in 2011. Research and development expenses were $16.6 million for the nine months ended September 30,

2012, compared to $16.1 million for the same period in 2011. The decrease in research and development expenses in the third quarter of 2012 over the comparable period in 2011 was primarily related to decreases in clinical trial expenses related to trials which had been substantially completed in 2011, offset in part by increases in costs associated with the Company’s ongoing lomitapide drug substance manufacturing validation campaign, and increased headcount required to support the Company’s regulatory and medical affairs activities. The increase in research and development expenses for the nine months ended September 30, 2012 over the nine months ended September 30, 2011 was primarily related to increases in headcount required to support the Company’s regulatory and medical affairs activities, and increases in costs associated with the Company’s ongoing drug substance manufacturing validation campaign, offset by decreases in clinical trial expenses related to trials which had been substantially completed in 2011.

General and administrative expenses were $8.2 million for the quarter ended September 30, 2012, compared to $3.3 million for the same period in 2011. General and administrative expenses were $21.0 million for the nine months ended September 30, 2012, compared to $9.6 million for the same period in 2011. The increases in general and administrative expenses in 2012 over the comparable periods in 2011 were primarily related to increased headcount to support potential commercial launch of lomitapide and in administrative functions.

Cash, cash equivalents and marketable securities totaled $95.5 million as of September 30, 2012, compared to $73.2 million as of December 31, 2011.
